tl;dr: No, they're not.
Thanks for saving me 15 minutes 👍
Thank you for the long story short
not all hero's wear capes!
I feel stupid now XD I just bought a nzxt h440 white, but everything on my desk is racer XD only the pc and the desk is white lol
didnt think so thank you though
Not as bad for your pc as installing norton antivirus
Yes. Mcafee and AVG are better. 100% truth. Maybe some people just have such bad habits that Norton is scanning their system 24/7? Or, I know! Maybe people download Norton without properly setting up the timers and firewall!
Of course, a pre-loaded version of Norton is another story. If that's the case, delete it and re-install it. An Antivirus should remain idle at CPU usage until a certain point in time, hence, timers. Midnight is the standard.

“Front mounted radiators are bad”

Cars are a joke to everyone. :p

Uh late but bad analogy.
Cars are using coolant unlike PCs
@@Socarolapex that's just so the water doesn't freeze.
Jay, you should redo this test!
up.
for those using celsius: 90% of the world

95.6*
right?
Yea as an American i awlays find it stupid that we use Fahrenheit and not Celsius
My science teacher in the Philippines was so mad when he asked her why American uses Fahrenheit instead of Kelvin or Celsius
Here's the science: It takes 0.07/h watts to heat one lb of air 1 degree F so it takes .005 watts/h to heat 1 cubic foot of air 1 degree F. A typical radiator fan (NF-F12 in this case) can blow 55 cubic feet of air per minute. For an 85 watt TDP CPU that means that the air leaving the radiator will be exactly 2.58 F or 1.43 C warmer than the temperature that enters and because air temperature delta equals processor temperature delta, it can be concluded that the GPU would be 1.43 C warmer with the radiator in the front.
The H100i with its stock fans (radiator impedance included) has a max flow rate of 77 CFM. Since you probably don't want those fans at full speed, it's fair to assume that the actual CFM will be closer to the 55 I used in my calculations.
+AniXFreakSXMe believe me, I would've loved to. The numbers were all posted in imperial and I didn't want to spend the extra time to convert it. Ultimately I did convert the answer to a usable unit however.
Spot on, the temp difference is negligible.
wouldn't have the radiator mounted in a "blow" configuration somewhere else in the case mean the air cooling the radiator would be hotter to begin with? seems like it wouldn't make much difference either way, in one case you are using cooler air to cool your radiator and in turn, all your components but as a result warmer air is blowing into the system (which is cooled by the radiator anyways) vs having the radiator cooled by air that's already flowed through the system and is warmer thus your radiator (and your components) aren't being cooled as efficiently. maybe i'm oversimplifying it but seems like kind of a dumb argument. besides we've been using front mounted radiators for cars since like, ever, and no one's found it to be a problem.
Rodiculous
Exactly the most important thing is to have air circulating, a few degrees warmer or cooler is not going to make any difference whether its entering the case through the rad or being blown out of the case through the rad.
I live in Scotland - my house is about 10C - do I even need fans?!
Yeah, cause they won't move it.
RyanGamingXbox - Gaming and more I disagree. You can achieve the same result by moving your case rapidly and constantly.
Kucing miu miu 😂
My comment is very late, but I'd say yeah you should have fans. Your RAM, MOSFETs, etc. on the motherboard need cooling and could explode if they get too hot. Seeing how your ambient temperature is very low, I think you can get away with running the fans at a very low rpm unless your PC components produce a lot of heat.

I'd stick with Celsius for temperature benchmarks, pretty much the standard in the PC industry.
Fahrenheit is more precise
Celcius is more accurate and is the standard in science and industry. Farenheit is left over from the 19th century, move with the times or be left behind.
>Celcius is more accurate
Wrong. Different scales don't affect accuracy. They affect precision though, and Fahrenheit wins in that regard due to having smaller units.
Fahrenheit gives you more precision without delving into decimals but decimals are an integral part of the metric system and the metric system is a design of functionality and simplicity.
In metric, one millilitre of water occupies one cubic centimetre of space, weighs one gram, and requires one calorie of energy to heat up one degree centigrade--which is one percent of the difference between its freezing point and its boiling point. The imperial system is a hodge podge of out dated measurement systems which do not work with each other in a cohesive manner.
Scientists use the Kelvin scale because it is an absolute temperature scale that relates directly to kinetic energy and volume and is considered to be the most desirable system to use for temperature but it is closer in relation to the Metric system than the Imperial system.
@@vimzim8576 Amen
Old video, but it's been proven by other sources that it's actually beneficial to have the radiator front mounted *when using an open shroud* styled GPU. It can keep the CPU cooler by up to 10C compared to top mounted. Blower style, not so much.
it's literally other way around
or maybe I would say it hugely depends on the case and airflow. if you have two big and good fans on the front, it really does not matter for the cpu temps, since those fans will provide enough fresh air for both gpu and cpu. and if you obstruct intake with radiator, gpu will suffer from less airflow
@mmmdawe so throw some fans in the bottom. It's pretty universally acknowledged that radiator it front, hose down is the best configuration.

love your vids buddy
Good guy JZ, gives temperature in both ºF and ºC
Jay, you need to compare CPU temperatures and performance between front mount radiator which draws in ambient air, and top mount radiator pushing out the heated case air. Surely the GPU heating up the internal temperature will impact the cooling efficiency of a top mount radiator. That would be good to see, giving clear benefit to using top mounts for the biggest heat producers like GPUs.
What’s the story after 8 years? Lol. Just got an AIO finally and I can only front install
@@drewQ8 Best is mounting it at the top if you can't then front/side is Fine, do take note that this is base on Case Design.
In your case since you can't mount it to the top front is fine.
In terms of pump Noise when pump is inside the block then Top is Best but i think your talking about temps here? Front will receive room ambient temp vs top while receive case ambient temp +2-3 C.
But Front AIO will increase case ambient temp by 1-3C.
A room ambient temp +1 will increase case ambient temp by +1 a case ambient temp +1 will increase all hardware temp by +1.
You would only really want AIO rad at the top when you do max frequency possible & tightest timing possible RAM OC since some Die-type are temp sensitive.
Also if you have M-atx standard case (PSU shroud below not dual chamber) then front mounted AIO do affect GPU temp but if its mid-tower cases not really much its due to restriction of airflow w/ M-atx non-chamber case design.
@@drewQ8 Comment is base in experience.. i have Top 360mm rad w/ push fans & 240mm front rad w/ push & pull fan and have two thermal prob located both at the front & rear of the case, can monitor case ambient temp in HWinfo since thermal prob came w/ MOBO and has built thermal sensor connectors.
Front is always 1-2C higher than ambient room temp while Rear is +2-3 C higher than Front which mean 4-5C higher than ambient room temp, Rear sensor is hotter due to GPU @ stock cooler (going to replace w/ water block & external Radiator & pump).
Just like the this vid, front will only increase 1-3C case ambient temp and if you have more rads temp increase will be lessen since CPU will not fully saturate the rads in my case its 1 degree C. inc. max of 2 C. during summer since its 36 C ambient here @ summer.
And that 1-2C inc. in my use case is only when running prime95 small FFT during stability test or android emulation for 5days straight maximizing all core & thread that's a 2 degree's inc. during summer.
But since your using an AIO then expect 3C or above same as the video.
@@drewQ8lol same here, I hope it’s not a big problem? Coz I was thinking of changing the whole damn case lol
TL;DW: No.

It might seem counterintuitive - and correct me if I'm wrong - but if you compare 2 different systems running at the same conditions, the one with the more effective overall cooling is the system with the higher temperature difference between the exhaust air and intake air (i.e. hotter exhaust). The 2 systems should be generating the same amount of heat, meaning the one with the higher exhaust temperature is removing more heat from the system.
In theory, front mounted radiators with intake fans should give you a lower CPU temperature as the the radiator is coming into contact with the coldest air possible, though it will make your other components hotter. Top mounted radiator should yield a higher CPU temperature but a lower temperature for the rest of your system.
The ultimate goal is to transfer as much heat to the air flowing through your system as possible, so you are looking for the largest possible temeprature gradient at as many points in your system as possible. I can imagine a lot of factors that can affect this though...so it's really hard to say.
Next do a comparison between 3-way SLI and 4-way SLI

A remake of this video would be good for the community to see. It seems many people missed this one
I noticed when I had my radiator for the CPU at the top, the GPU would heat my CPU up too 75C, but putting it at the front, I only go to 64C and there is cold air blowing through the radiator. GPU went up by 1-2C after the CPU radiator was put on the front.
Who's here after the Gamers Nexus video about people mounting radiators wrong
Here. I didn’t watch the video. It was too long. Couldn’t find the part where they explained their side on front mounted radiators. What did they conclude?
@@johncena-zo1uf If it's front mounted, the tubes should be at the bottom of the radiator.
@@LettuceLand thanks bruh. Just remounted my aio. The hassle.
yep
@@LettuceLand do you have any pic of that?
why so complicated? i get your point but wouldnt it have been way easier (and more accurate even) to look at system temps with the rad in the front vs the rad in the top instead of all this theoretical stuff?
maybe running a stress test on your gpu affects the gpu and vice versa, nobody can know.
I can't stop admiring the color scheme of your setup in the background.
It still amazes me how components can reach temps that high and still function!!
correct me if im wrong but using common sense a front mounted radiator is the best option. heat RISES so you often put ur exhaust fan on the top of the case. you wouldnt want to pull or push warm exhaust air thru ur radiatior nor is making the top an intake very efficient due to the fact that heat rises
Good findings again.
That Titan was putting out HOW much Celsius? Wild.
thanks for doing this video wish you had done it earlier. I had this problem in my case with the gpu heating the air in the case so much that the radiator mounted at the top was constantly spinning the fans at max rpm. the noise level was too much for me and I mounted the radiator in the front instead. noise and temps went down a lot, but I like the look of a radiator mounted at the top more.
I think the question should be, would you choose to have cool air drawing in from the front or warm air? which is more efficient? Naturally you would choose to have cool air drawing in, of course the system won't overheat with front mounted rad, but as tech enthusiasts I think most people want what's more efficient even if it may be a bit ocd
You have good case ventilation. I'd rather have the AIO as exhaust though to minimize the need for more fans.
Heh, "all the components across the board".
If you think about it, don't cars have front mounted radiators? And the warm air from them passes over the engine.
"Now, I'm not using an opinion here, I'm using a thermometer" your best quote man haha
real mug/t-shirt level gold :P
LMAO, went to rewatch this video and of course the beginning video ad is the Honey ad hosted by Linus!! Linus narrating an ad on JayzTwoCents video... the world is ending lol
Doesn't seem like it would be a problem but I've always thought it was more ideal to have intake fans on the front of your case and then a radiator mounted on the top panel as exhaust. I feel like it's better for equalizing incoming air and air exiting your system.
It's a different story when you have a lot of heat to dissipate (both CPU and GPU watercooled) with more than one radiator. If the intake air is already warmed up due the heat dissipation in the first radiator, there wont be a lot heat dissipation in the second radiator. It'd be like trying to cool something with a hair dryer (or something else that blows warm air).
Naturally the position of the radiator doesn't matter if there's only one of them in the case.
Thanks, exactly what I wanted to know. I was considering an AIO water cooler, but realized the only way I could mount a 2 or 3 fan radiator in my case would be on the front panel. I figured it would only increase case temp a couple degrees, but it's nice to know.
Well, I'm a year later. But thanks Jay.. you are really great. Building new setup with WC and this helps on my research.
I mean it, Thank you =)
Keyllan same!
"gaming does not put a huge load on the cpu" - *cries in 4 cores with no hyperthreading*
Jay: shutting down the trolls. love this dude.
A Linus ad came on before this video and i was really confused
Jay, u could compare using H440. By using radiator at front and top, and compare them. U could use fans at push, pull and push/pull. Thks!
Sometimes the stupidity of people concerns me. Of course having a front rad is going to slightly increase the temperature of the air going into the case. But if that front rad is pumping out so much heat that it could potentially damage your system, having it at the front is the least of your concerns.
+Casual Alien Saying a rad on the front heats up your system is not stupidity what is stupidity is taking one single example and then concluding from the results that its fact that it does not. The reality is a radiator on the front will indeed increase temps but it all depends on the system its self as to much it will be effected for example type of CPU/GPU/size of radiator. In my case I have a FX6300 a 95w CPU / GTX970 with a non blower style cooler and because of my case I could not use a 240mm AIO so had to go with a 120mm AIO.
The idle CPU temp was around 26c and gaming load is around 40c to 50c pretty decent temps for an AMD but when I moved the rad around looking for the best system temps with it at the front the GPU temp increased by around 18C and GPU boost was limiting the clock speed way bellow its potential the mobo NB was running 21c hotter and ram also seen a jump in temps to the point they were physically hot to the touch but when I moved the rad to the back as an exhaust my CPU temps went up by like 2c but everything else came way down in temp GPU / NB / and ram was now cold to the touch and GPU boost was now running at the max boost speed. You might say well its only around 20c more but that is allot when a card is already running at 65-70c because if a card is at 70c and you add 18c that's 88c and while this is not a system killer it is a GPU boost killer and it will kill the performance as GPU boost is reliant on temps and the hotter the card the lower the clock speed to the point where it can even throttle it.
Smart people will take multiple tests covering multiple situations and combinations ( like they do in real science ) where as stupid people will take one test example and conclude it as fact.
+EQUINOX What case, and fan setup do you have? Because almost 20C difference just sounds like way to much. I have a CM Seidon 120V on an OCed i7 950, and I've had it oriented where the fan was intake, and then exhaust, mounted at the back so it was literally right next to the NB and at most I maybe saw a difference of 3-5C on it.
+EQUINOX that has nothing to do with hot air going to the gpu, that's cause your gpu isn't getting as much air as it would if you just had an unresticted fan.
givemeajackson No offence but do you even know what you are talking about? It has every thing to do with hot air coming out the rad and it also has everything to do with reduced air flow into the case. The GPU cools its self by pulling in air from the case and this air usual comes from the front fan and the cooler the air the cooler the GPU so rather than an unrestricted fan pushing fresh cool air to the GPU you have a fan with reduced air flow pushing hot air so not only does the GPU have less air flow but it is also being feed with hot air. If you cant grasp that then think of it this way you're in a room on a treadmill and you are hot and sweating and someone turns on a fan heater that then blows hot air onto you what do you think is going to happen? That's right you are going to get even hotter.
EQUINOX the problem isn't the temperature of the air, it's the amount of air. my s340 has a 280mm rad as the only intake, and guess what? if the fans are PWM-controlled, the more load i put on the cpu (5820k @ 4.5ghz and 1.3 volts), the cooler my gpu gets (înno3d gtx 980 airboss x4, 63° in furmark without any cpu stress test, 49 when running aida64 simultaneously) if i hold my hand against the radiator if it's running aida64, the temperature of the air coming through is barely above ambient. we are talking about a difference of maybe 1-2° C. the problem is entirely down to restriction, not heat dissipated by the rad. solution: push pull, or simply better fans. many AIO units come with absolutely shit fans, my nepton 280l included. also, check if your fan seals properly against the radiator. some idiot companys (like cooler master, and corsair on some of their products) think it's a good idea to put a round fan on a square radiator. all the air is blown onto the rad and exits out the side with barely any actually going through the rad.
Glad I caught this video. My plans for my next build involved a front mounted rad (along with a top).
Why can't we have a PC Case that has a separate chamber to mount the radiator in so that it does not take in or exhaust into the main chamber of the case where all the components are at?
Make a radiator mounting chamber on the right side of the case with the radiator mounted on the front and the exhaust exits thru the back of the case. Leave a hole big enough to run the heat sink and hoses thru, with some kind of split rubber grommet/gasket to seal around the hoses, into the main chamber.
Front mounted radiator is actually better than rear mounted one. Cooler CPU.
You know the reason why ?
Yeah, but what looks *cooler*
A E S T H E T I C 5. Puns
Can we get an updated video about aios and liquid temperatures?
Glad i saw this video.
I recently modded an old Asetek LCLC 120mm AIO to maximize cooling in a HP Z420 Workstation case :D
90mm Rad in the Rear, 120mm Front, 150mm Reservoir, 6/8mm Softtube. Both with single fans as pull.
Cycle is: CPU - 90mm (700 rpm) - 120mm (1400 rpm) - Res
CPU 60°C, GPU 75°C (Ryzen 5 1600x, GTX 1060)
Works fine, silent enough. My only concern so far is the single 120mm fan in the front is the only intake and has to provide airflow to the gpu, top mount PSU is ony other exit apart the mesh pcie slots. Case has fully closed sides, front, bottom.
It makes more sense to get a case that supports a front and top mounted radiator.
Mount the radiator at the front as an intake and messure the temperatures of GPU and CPU.
Then mount the radiator at the top as an outtake and do the same.
Also put the ambient room temperature in there and let us know the delta temperature as a result. That is a lot more accurate.
You should also do that test without any additional case fans, cause that can change the results dramatically, depending on where they are located.
I think your testing method is very inaccurate.
Not really linus tech tips has a video showing something similar. those radiators are nowhere near 100% efficient. although in this case exhaust makes sense as you can have 2 fans at the front so get positive pressure
+taief miah I don't think you did understand my comment, because your arguement doesn't apply to my comment. Can you link me the video from LTT please?
Senzelian it's one of the most recent ones testing number of case fans and placement (where) and then comparing gpu and cpu temps just released this week I'm currently doing something else. Besides gpu cooling performance is constant even still all you need to do is see his measurements of air passing through the radiator against room temperature as that is your delta in temperature entering the case. As gpus go at a certain performance they produce the same amount of power and heat therefore the thermal energy produced by the gpu is going to be constant so the difference should always be less than the delta. However running both cpu intestine and gpu intensive tasks simultaneously will show nothing in real term performance as nothing bar benchmarks makes both perform at peak simultaneously
+taief miah Oh you mean that video. Yeah I have seen that one and because of it I think he should messure it without case fans and just use radiator fans.
I think if you have your radiator mounted to the front as an intake, then CPU temps will be lower and GPU temps higher and if you mount it to the top as an exhaust it will be the other way around. The performance differences you're talking about don't interest me. And that's my whole point. And I would like to see some test and not just theorys.
I also don't like how Jay doesn't have any consistency in his "tests".
Senzelian not necessarily the gpu being at the bottom of the case meaning that although it intakes out or midway through it will most likely dissipate through the back. Either way the radiator isn't 100% efficient initially so a minor rise in temps is not that big of a deal. As not all air flows through the intake to the decided exhaust. Again a lot of what we have to work with is theory almost everywhere in science . Most of this is easy to understand with simple understanding of the way these systems work
If the tubes are up its probably gonna pump air. Most aio's cant reach a front mount with tubes on the bottom... so that's bad.
Hi, I’ve about to get the NZXT z73 on the case p500a, so I’m wondering if the radiator better sitting on top of the case or in front of the case please?
@@tikkoy8396 top is better
@@Ali-pt2vy thoughts about a 360 radiator on the meshify 2? (case)
As long as the top of the radiator is higher then the pump you are going to be fine.
Jay I fuckin love you. Most of these things are pure science but it's fantastical that you make all these videos for people that aren't so PC savvy. Professional quality and nice, detailed explanations. Make the "I digress" tshirt and take my money already jeez.
Haha, I just noticed that your background picture is a exhaust flame from your PC. Love it!
The FuryX is awesome, because it pushes all the hot air out (I have mine on the top of the case, 100% of the heat is ejected)
I'd never put a radiator pushing that heat into my case, I mean that FuryX produces a LOT of heat, you can literally warm your hands from it.
guess why it generates so much heat. amd
TheArtVe the gud Yes it runs cooler than the 980 ti and TitanX - Nvidia is the hot cake now my friend. (even the air cooled Fury runs cooler than both of those cards)
PS: jay's? Room must be quite small for the GPU to manipulate the ambient temperature so much.
I have 5 gaming rigs (In my admittedly very large room) always running and they don't make "much" of a difference, - 1 FuryX rig, 2 290xs, and 2 R9 270xs.
I wanna case with top exhaust too. I can warm my hands with my Psu tho
+Patriot 03 close but nope. his name is jay :p
i love it when Jay reks the newbs
A problem occurs when your GPU blow the hot air inside your case (all custom gpu).
JayzTwoCents have a 50°C out from the GPU if you put this hot air in the case and you add the hot air from the front radiator the temperature start to grow very fast and you can reach 40°C on your MoBo ( try by myself).
To resume if you put the radiator in front your cpu is cool but your system is hot
If you put the radiator on the top the cpu is hot but the system is cool (relative to the first case)
Thank you for making this. I am a newb and I was forced to hook the radiator of my H110i to the front of my master case pro5. I had the intention of mounting it on top, but there wasn't enough clearance for the radiator. Plus it was a pain trying to line it up. I ended up going with the front mount. I haven't yet bought my graphics card yet (Waiting on Pascal) so I haven't been able to heat up my system. Watching your video makes me think I'll be alright. Thanks
Thanks so much man! I'm planning on doing a build in the Fractal Design Define R5 and didn't want to compromise the silence by removing the covers up top to mount my radiator. I'm happy to know that I won't have much to worry about by mounting it up front. Keep up the good work, Jay! I'm learning more and more every day from your channel.
if you pushing air out of case thru radiator arent you trying to cool radiator with hot air ?
Pasotintojas1 he's pulling in air through the front and that's where the radiator is
A Hobo Panda
i know :))))) not that stupid :)))))but most people put radiator at a top and pushing out im asking about that
A Hobo Panda isn't that pulling or pushing the hot air that the rad is attempting to disperse into the case, then? It's strange if that's the case how he's able to get such low temps
It's a give - take situation, yes you are pulling warm air through the rad but your also pulling it out of the case. What I do is install a front rad and mount the fans pulling cooler air into the case and using the larger rad at the top pulling it out. Only makes a degree or two difference but I do it anyway.
radiators ment to cool liquid that goes thru it so it can cool cpu or whatever you are cooling why da fuck its called cooling solution when ? Its...
Hey JayZ. Thanks for this vid! just got my NZXT S340 Elite and mounted my Radiator in front blowing inside and with the top and rear exhausting. All is working well.
Thanks for the Tips! Keep up the good work
Look at baby Jay! 😅👉👈 This reminds me of when I first started following the channel! I needed this refresher! Thanks Jay!
Thanks for putting some of the bullshit misinformation out there to rest, Jay! I've been thinking about this lately and I'm curious to find out whether ~30% exhaust (largely positive pressure and all intake through radiators) is sufficient to maintain reasonable case temps with both cpu and gpu under water, but the overall message of this video was encouraging.
I'll keep my AIO in the front, thanks Jay!
Bitwit has made a video about this switching between blower style and a "regular" card. He found out that (if I recall correctly) that it does not matter for either CPU or GPU when having a blower style GPU.
But with a "regular" card, the GPU temps are still not influenced significantly but the CPU temps differ 10 degrees C. When the radiator is mounted above the mobo, the cpu went up by 10 degrees C compared to mounting it in the front.
I'm going to mount mine in the front for sure (don't have a choice anyway because I do not have space for a 240mm rad above my mobo)
Just finished setting up my rad for the front... then I saw the title for this. Bummed out for a minute, then watched the video. I feel a lot better now haha.

You should just use Celsius and save yourself the trouble of repeating both all the time. Eventually everyone will get used to it.
i haven't personally ever recommended Exhaust mounted Radiators because intake mounting is going to 'break your computer' - i only personaly suggest Exahust Radiators because one or two degrees on your Liquid loop is a small price to pay for any extra cooling capacity the components that don't have access to beefy Heatsinks.
the components you talked about that you didn't have the practical way to test temperatures on, are the ones i'm basically thinking of in this situation.
VRM's, Mosfets, and System Memory (and North Bridge on older machines) already can get quite toasty. if i can reduce their temperatures by increasing the CPU/GPU Temperatures one or two degrees, i'll gladly do it.
as again, the components with the beefy Heatsinks and Liquid Cooling are already doing pretty well, they won't mind.
but yeah, intake mounted Radiators isn't some devil sin. just a little bit less ideal IMO.
the heated air coming through the front radiator should be barely hotter to affect more than one degree on other components. This has already been tested.
@@MrRaphaelLippi
you need to learn how to read.
i said in exact words in quite some detail that my preferences for Radiator placement is based on all of the components OTHER THAN THE FUCKING CPU AND GPU.
things that have little to no cooling themselves and whatever less restricted air they can get to help overcome that, the better since people tend to have sealed up RGB boxes with inadequate cooling all around.
especially the smaller SMD's that go implied here.
learn how to read.
oh, and also, learn how to read.
the volume of air absorbs the heat and is very low difererence. if you decrease the times of same volume of air change in the chamber then you see a increase in the temperature.

Thanks Jay,was just trying to make sense of mounting the h110i and the front does look like a nice home for that rad.
Jay, I agree with the test. And I would say that the front mount radiator would have more "problem" if you don't created a good airflow in the case, because than you have the warm air stuck into the case.
"we wanna pump some heat" then uses 14nm chip. use a 3930k or something. the old x79 boards mosfets would get 100c+. more heat is coming from the vrm than the cpu or rad. i have a 3930k and the heat from my mosfet heatsink over 2 years combined with power draw of the cpu melted the connector on my 8 pin power and caused the psu to short. i can feel an extreme heatwave coming out of the exhausts when its under load. way more than 3 degrees above ambient as your tests show. probably like 20-30f higher than ambient. cpu is only 70c at 4.4 which brings up another question how a 6 core 32nm chip at 4.4 1.32v runs 30c cooler than a 4 core 14nm at 4.7 with less voltage. also using an h100i btw. forget the thermal paste of something? lots of questionable choices in your test methodology
Heat us not temperature. 6700ks don't pump lots of heat, but their temperatures can be pretty high. As you decrease chip size, heat gets spread over a smaller surface. When dissipating heat, temperature is what matters because that's the density of the chip. Also, he has a 6700k system built already, bot worth the hassle to build a new PC. If you disagree with all I say, at least acknowledge that.
+EZOVERDOSE or just use amd - Kappa
+MisterBlack83 Please get your twitch memes out of here. That said, you're right. Every cpu heatsink should be tested on an overclocked Centurion.
+EZOVERDOSE There is nothing wrong with his testing methodology. It's an apple to apple comparison. If it doesn't increase here it wont increase anywhere else.
jeroen wilmink
he shouldve used something that made a ton of heat to exaggerate the situation for a worst case scenario. not the smallest die most efficient low heat chip on the market for a best case scenario
Why think in 2 dimensions.
Why not just turn the fans around and make the front of the PC the exit instead of the intake.
Or both the back AND the front as outlet and the sides (or mabye even the top and bottom) as intake.
Air doesn't have to go from front to back.
Because everybody does it like that doesn't mean that you have to do it like that too.
air filter also the back has 1 fan slot. makes more sense to exhaust through top with rad and have 2 intake fans at front. (due to convection and dust filters). that way you also have postie pressure. BT it's also due to the way most cpu coolers are installed and ways to reach the gpu. intake at the back will hit the cpu first but won't go to the gpu. again it's the way cases are designed. to cover the whole cade with intake from the front
***** this is air ebeingbheated so convection is a thing. It doesn't travel up the sides of the case as per say. Convection is also a factor for how aire moves in a room. Also static pressure fans are to help with cooling a radiator. For cade fans you want high airflow ones
+MsUltrafox Depending on the case, that could work. I'd like to see a followup video with that test actually. If you had a fan or two at the bottom of the case, it should work no problem.
+MsUltrafox This. I currently have 3 radiators (CPU+2GPUs) inside my PC. All of them act as exhausts. While doing tests it was clear that blowing hot air outside the case was better but It was important to provide enough air to feed the fans. So I did a little test, measured the air flow while the case was open, then gradually closed the case to find the smallest opening required to keep a good flow from the fans then modded the window and added a filtered mesh on a new laser cut acrylic window. More cool air is coming from 2 bottom filtered fans so my whole heat dissipation happens in a down-up motion. Fan speed at 950~ rpm, very silent. I'm happy with it.
+davidcapi that actually sounds like a good way to do it. I have a 240 top mounted as exhaust (cpu) and a 360 front mounted also exhaust (gpu), as well as a rear exhaust. I've had nothing but low temps however I'm going to try your bottom filtered intake fans x 2 and check for any changes.
I think a lot has to do with air flow. I was running a CORSAIR Hydro Series H55 with a Kraken G10 on an HD 7970. the radiator was mounted in the bottom of the case in pull exaust.
I noticed the air coming from under my case was pretty warm when I was running Valley, so I added a second fan in push, the air flow went up and the air no longer felt so warm. The slower the air moves through the fins the more heat it picks up. With higher air flow it still picks up the heat but the heat is spread over a lot more air.
I have an H80i with push and pull fans mounted in same spot as you in this video, 2500k 4.2ghz/1.275v, the air coming out of the top exhaust does heat up about 5 degrees or so when the cpu is over 50% on all 4 cores.
Jay this test seems too unscientific to me. A better test would have been to try moving the radiator to different locations around the case to demonstrate that the GPU/motherboard temperatures were not significantly affected by the position of the CPU cooler.
A proper result.

more radiators are better, radiators in the front are better than not having radiators in the front!
+BackinBlack are you suggesting that water cooling is better than no water cooling? or something..?
Michael Dyer Im suggesting that more is always better, even if you don't need it.. t still better and cooler.... wtf
+BackinBlack I think that you could have really bad water cooling or really good air cooling, air would be better.
matt beef sure.. if you dont have enough rads... but honestly anything over 120mm X 120mm X 30mm rad for each component will generally be better than air. anything over that should be great. otherwise position of rads does not make that big of a difference... number of rads is more important.
BackinBlack true
I just have my front 200mm rad exhausting and my top 240mm exhausting as well. If you only have one radiator I guess it won't make that much difference but when I feel the hot air blowing out the front of mine I am very glad it isn't going back through the top rad! there are 140 (rear) 120 (bottom) and 200 (side) fan intakes in my case so the rads have good airflow.
Basically whether it's better to set a radiator up as intake or exhaust depends on whether you're going for maximum CPU cooling or better all around cooling.
-Setting it up as intake will allow for the max possible CPU cooling, but the trade off is that you're slightly reducing the cooling effectiveness of every other component, since you're dumping all that heat right back into your case.
-Setting it up as exhaust slightly reduces CPU cooling performance, but since you're immediately exhausting that heat, overall case temps will be a little lower and your other components will be able to cool a little better.
Personally, I have my h100i configured to exhaust out the top. It works just fine that way. My 4790k temps never exceed 70C and the waterblock temp never exceeds about 40C in a 25C room.
"For those of you who use celcius", you mean, "The rest of the world"?
Do you feel special now that you stated that... you know he didn't say for those few or those of majority who use Celsius... right? He actually just said for those of you so use Celsius. That's not negative or derogatory
Sisrace I mean, there's 320+ million people around me that use Fahrenheit.
Nihlus and there is at least 5 billion+ who use Celsius. What's your point?
Who Cares Celsius is for plebs
They switched to Celcius to make it simpler for kiddies to learn it, who needs simplicity, seriously, just fucking get smart m9. If you're too stupid for IMPERIAL, you can just find a nice bridge and have at it.
thx for doing °c .. i was expecting american numbers that i dont understand
+Pálmar Sig It's actually pretty funny how much America has transitioned to metric, etc without us really noticing. I think this is mostly because there's a world economy. We see it in auto (5.0L engine), beverage (2L soda) and so on.
Its funny how you low lives bitch about americans and how bothered you low lives are yet americans dont give a sht about you. Hahahaha
@@blaaaaaaaa2017 Nobody care about you morons.
Pálmar Sig PCs only record temps in Celsius...
@@blumac9801 pretty much
case temps are usually reliant on the room temp, if the room is cool the case will be cool. unless you have a mini itx where air generally doesnt have room to flow, anything above that micro atx or higher should not affect the case temps. I think people are over estimating how hot a radiator can get, its not like a car where the radiator can boil water.
Your builds have come a long way, Jay.
After 12 minutes, I am a bit lost what the conclusion is.
Nothing is planned or tabulated.
Why is anything happening ??
Too many words.
He got no conclusion .. cause he is completely wrong.
FRONT OR TOP WHAT DO I CHOOSE?!?!
For those who use celsius. 96,5% of the world
96.5%* most of the world uses a proper decimal.
So many people act like they know physics and thermodynamics. At least somebody was willing to do a actual test about it. Was there problems? Yeah, but Jay isn't a scientist so don't go crazy saying "This experiment is invalid because ....." Good video +JayzTwoCents
Thanks man. Got a smaller profile case thing going on and looking at this. Makes me feel a lot better. :P I'll be going for it. So thanks!
I like the "other word"
I fixed my car radiator on roof. Now hot air don't come in
Jay the only arguement really hear about front mounted radiators has to do with premature pump failure because the radiator is mounted too low or the pump is too high in the loop causing premature failure.
this was 5 years ago lol
If it is a blower style card put it on top but if it is not the put it on the front to get the most optimal cooling.
OC3D used to run 2x 295x2 front mounted and he said his case is hot to touch, lol
+Sadaki I think the difference here is CPU vs GPU. Not a big deal for CPU but yeah, not a good idea to have the GPU radiator front mounted.
Yeah but thats a 550 watt gpu vs a 91 watt cpu.
+Sadaki you are out of topic you know that right?
+Cirno does that matter? we could of been talking about fallout 4
+applemaggot I have my Titans front mounted with no issues. Helps to have a good case too, with good fans.
Hmm. A 19 minute Gatorade ad. Starting to see the upside of UA-cam Red now. :D
Can't you switch the fans to the top of the rad in top mount position to pull the cool air from outside just like in the front mount position?
just because you have a front mounted radiator, doesn't mean you "MUST" pull air in. If your case is vented, you can actually blow the heat out the front of the case. There is no rule anywhere saying that front fans must pull air in. Plus too by "exhausting" the hot air out the front, it makes cleaning the dust off the radiator a "LOT" easier.
To save 17 minutes where should I put the radiatior?
Outside the computer case is the best :) No heat going inside and it does not draw in hot air from rest of computer system.
I do that but with aircooling... Even my GTX980ti max overclocked at 100% never get over 60C (can not get it lower as that is as low as the automatic fan setting allow)
In the water
I've just turned my fridge into a pc so I never have heat problems.
You will have heat problems when the fridge dies because it is running too much, assuming your fridge is capable of cooling the PC now.
+befru I think Darren ment it ironicly..
+FLUX indeed
Linus already done it.And.. There is nothing happen plus the temperature in the fridge increase. sooo. no ... DO NOT PUT YOUR GAMING PC IN THE FRIDGE. Xcept freezer. that is ok i thing.....
+HAZARDIE amir What the heck is a linus
If you're testing the temps and radiator placement, you should have used a card that didn't vent through the rear as most people don't use a titan. Would have been nice to see the temp difference when moving the radiator from the front to the top and also using front and top radiators. I know it's only a 3 - 8 degree typically difference depending on the case and air flow, but it would help others understand.
I don't OC and using the stock cooler that came with my 3600XT so I have no use for a radiator, but I still like to see stuff like this.
I was going to write this in response to someone else, but since it seems like so many people don't fully understand I'll post it here: the laws of thermodynamics state that heat will always move from a hotter place to a cooler place.
In the case of watercooling, a pump pushes a lower temperature coolant over a hot component and it picks up the heat from it. This in turn has to dump that heat to somewhere cooler at a rate equal or greater than it is being introduced, otherwise the coolant temperature would continue to rise uninhibited along with the components being cooled (heatsoak). Obviously, the radiator does this by dumping heat to the atmosphere. If the atmospheric air going through the radiator is not less than the temperature of the coolant the heat will not move anywhere - no matter how big it is or how fast the fans are running.
In any watercooling system, the aim is to have more than enough radiator surface area to get the temperature of the coolant down as close to ambient temperature as possible, ideally without having to run high speed fans. One thing Jay only touched on at the end for front-mounted radiators was the issue of case temps being slightly increased for the components relying only on air cooling. If you can get all the big heat-producing components watercooled, having the radiators at the front is even less of an issue and may even yield a slight improvement for those components. This is because the cooler the air that's being pushed through the radiator is, the greater the temperature drop of the coolant will be (assuming decent efficiency), which in turn drops the temperatures of those components being cooled. Are the other air-cooled components going to show a slight increase in temperature? Yes, but practically within margin of error as demonstrated by Jay and definitely not to their detriment. I highly doubt a 2 degree rise in MOSFET temps are going to impact anyone's overclocking headroom.
This is also why delta-T should be used: to get an idea how many degrees above ambient the system is. The lower the delta-T, the more efficient your cooling is. If you had a 100% efficient cooling system, the delta-T would be zero. If your system somehow manages to get below ambient temperature (a negative delta-T), you should probably be awarded the Nobel prize in physics.
