I always go with enough fans to make the case hover off my desk
xD
+Second Burst Very True. It becomes difficult to clean it sometimes when it floats away though lol
Not enough, it needs to outperform a commercial airliner
+That Guy Sully Nah just install the fans ON the desk then your monitors hover too
AzBo Gaming I agree, it's very minimal. I honestly just put a fan in every spot that is made for one and it works wonders
I'm really enjoying this "older" videos, when we got useful information for plebs like me without top of the line hardware.
I enjoyed Luke's workshop videos, too bad they didn't make too many of them.
Somebody knows why now only linus is in every video?
@@darkwowpg Maybe because it's called Linus Tech Tips? Just a wild guess out of the blue.
He works at Floatplane now I think
@@darkwowpg luke works for floatplane
That guy at the end really couldn't wait 30 seconds for him to finish recording huh? lmao
that looks bad
@@operadores2 yeahh, guess he really just doesn't give a fuuuck 😅
how can you come in to a video not even say hello and doing your thing.... moron'
So F disrespectful!
you guys know that was part of the 'show' right? just to emphasize Luke is in a hurry XD
Steps:
1. Locate all places where a fan could physically fit
2. Fill these places with Noctua
Nope I fill mine with Ezdiy rgb fans because how much of a good deal they are
I feel like Inwin fans are underrated though. Good value and RGB that doesn't suck ass compared to other non-RGB fans in the market
Make sure fir them to be 3000rpm do it can fly
@@pipeqez911 I have those fans to they are great they should be more popular.!!
Any PC that has fewer than 8 Noctua fans (3 exhaust, 3 intake, 2 for your NH-U12S) is unworthy of being called a PC.
Why buy fans when I can just manually blow air into the system?
Because, as a nerd, you're supposed to be productively lazy. Outsource the air blowing to your fans. Duh.
Build a UA-cam channel, and have your fans come over and blow air into your case. Problem solved.
dude just fart into it. that'd neutralize the air.
You can liquid cool it with urine
Or spend $10 for a small desk fan add just have it blow into the case
Gosh... can you stop joking?!
Can’t you just download more cooling ?
Naaa u need more RGB...
Lol made my day😂
no that's illegal. You have to buy the dvd
nana, RBG is for those higher fps. common knowlegde

Once my tower is 5 decibels louder than a Huey helicopter I know I've installed enough fans.
Why not just install a Huey in your in your pc?
If you play Rising Storm 2: Vietnam it would be very immersive
@@bigboyexpress6668 I did that a few weeks ago, now my house is boobytrapped and i keep finding tunnels in my floor
@@maxvisser9528 I also installed a Huey and, for good measure, I also put in a sabre engine so that I can effectively remove heat from the case and use it for heating my hot coco
Can relate
I have three fans intake, three exhaust, not counting the ones on the CPU cooler or video card. I read at least 10 emails a day, so you can never be too safe! :P
Meh, I'd rather have an additional 500 GB SSD then. ;)
it's better to have more intake than exhaust
@@Zeroneii3 why?
@@Banana-sb1hi reduces dust
basically it's better in the long term
@@Zeroneii3 Um....no. The better the air moves straight through with no "kinks" the better. Try putting some smoke through so you can see the flow. I test mine several times a day....;)
There's only space for 5 120s in my Neo Air case. two front, two top, one rear. But I still fit 6. I front mounted a 120 AIO with push pull fans.

stop stealing comments 🤡
I like how this is recommended to me the day after I installed 9 more fans into my pc and upgraded 2 others to bring my total fan count to 21.
you can fit that many? All 120mm right?
@@BB-nq5cxnot all 120mm. On my intake I have 2 200mm fans, and then behind it are 3 140mm fans. The 200mm look nice but considering the front is tempered glass, I do need more static pressure than the 200mms can provide. On my CPU 360mm rad, which is mounted on the side of the case, I have 6 120mm, and then my gpu rad, which is also 360mm, has 6 120mm fans as well. Then my exhaust fan is a 140mm. The other 3 are the chipset fan, (x570), the gpu vrm fan which is 92mm, and then the psu fan, which is 130mm or something weird like that.
@@dapz oh I didn't know we were counting built in fans (like psu and gpu ones). also I didn't realise there were 200mm ones. You must have a massive case right?
@@BB-nq5cx yeah, its pretty big, and wide too.200mm fans are one of the largest fans you can commonly find in pcs, though 250mm fans have been made for pcs, just very uncommon. not including built in fans i would have 18. its about 65 decibels at full volume, i actually have a vid of it on my channel.
@@dapz oh nice. That is, a lot
Intake and exhaust orientation should've been mentioned.
I agree completely.
hey i wanna ask something, if i put radiator in front panel, it's better to use push or pull fan setup? thanks b4
+hadron89 In my Define R4 I would do intake front and bottom, so that's three fans intake. 2 140 in front (with filter) and one high pressure fan at the bottom. Now with the exhaust, I have a H80i and the fan is pulling instead of pushing air on the fins. I have two 140s at the top exhausting also. So that's three intake and three exhaust which is neutral air pressure.
+hadron89 or bottom if your case allows it.
+EmbeddedGenius But bottom sucks more dust as dust falls down onto surfaces.
Enough fans to feel the breeze from the PC in your face!
+TechSource oh hi there! love your vids man
+TechSource It gotta be cold if you feel it, right?
funny seeing you hear was just watching your episode 23 set up wars
Or the heatwave if you're on amd
+TechSource yo mom
This is easily one of the most useful videos. Coming from a stock Dell XPS Desktop setup, I think just adding 1 front fan would make a lot of difference.
I have the same, added the iograded heatsink and fan, i9, 3080, a noctua too fan and maybe will add a 2nd noctua. People arw crazy to expect better. Its hated on but enough for gaming and great at desktop and I added more RAM just in case haha.
It's amazing they didn't mention fan orientation although it IS possible to tell by watching the video, The "back" side of a fan (where visible wires run along the frame towards center) is the side air will be blowing towards, so for example at 9:28 - 9:30 when it shows the closeup of the top fan you can see the wires so it is setup as an Exhaust fan. We can of course assume the front & rear fan orientation as it wouldn't make any sense otherwise (rear = exhaust / front = intake).
Awesome video Luke! Would love another test for positive/negative setups with one, two, three fans at different locations on the case...hmmm... maybe a video idea for something i should do :p
Yesssss Plzzzzzz
I love that I can't help but read your comment in your accent xD
+HardwareCanucks yes do it. just do it. please do it.
+HardwareCanucks c'mon, do it, i'm so curious! and of course i love your style :D
+HardwareCanucks and one fan. lots of cases only come with the one in back, like mine.

@@larry570 Years ago, I saw a build on a forum. They got a bar fridge, built the PC inside, drilled holes for the cables & sealed them with silicone, then put in a TON of moisture absorbers.
Ran pretty cool, overclocked real well.
12:25 My friend when they don't care what I'm saying
Thank you for making and posting this video. It's helped me understand the cooling requirements for a build I'd like to undertake. Thank you again.
Kudos to Canada for using degrees Celsius!
+Dmytro Lienko #metricmasterrace
The superior measurement
Computer temps are just in Celsius as a standard, even in America. Not sure why.
+David Dao Because the USA is basically the only country left that uses Fahrenheit as the normal.
+Dmytro Lienko They tried to get metric going in the US didn't they? Americans just got too confused. Like wtf 'murica. They use "calories" instead of kilocalories. So if you try to explain to them how much joules go in a calorie they'll think you're off by a factor of 1000.
Super finds Luke! One interesting thing I've found through my own experiments is that having a *direct* flow of air to a particular component helps temperatures significantly (rather than having to go around components etc). Not something that's easily done in a normal case unfortunately though.
+DIY Perks Well you also designed your own case to take advantaje of that ;)
+DIY Perks It's also easier to get direct airflow on a GPU with a CPU tower heatsink as in your build. Out of curiousity, how much did it cost you to build a case rather than buy one?
+DIY Perks Your case is superior in design to what anyone could find out on the market. The closest thing that I could find to it was the Silverstone FT05 (or RV05). These cases have the rotated motherboard design and also have VERY good case fans that provide direct flow of air, the Silverstone Air Penetrators. But a case like this doesn't have room for a tower heatsink on gpu like yours does.
+Daniel Schulz The whole case itself cost only £50 in materials iirc, including the wrap and paint etc.
No shit m8 ...
Looking back at the old videos, the improvement in production quality is massive. Audio is so much more crisp, and the lighting is perfect and diffused. And that's just at first glance.
Missing Luke hosted videos though lol
Also the obnoxious music is gone
Always enjoy going back to see how far they have come. Luke with more to say, "So, a" cuts to tunnel bear. And then the tunnel bear notes on his phone on the desk.
The other guy seemed pissed you were using his stuff haha
I kinda dislike that while the sets seem to be more professional, ltt seems to be moving towards more of a vloggy handcam direction with less concise points and more view into the background of the videos. I feel like its almost more behind the scenes than actual content.
couldn't agree more.
actually, thinking about it, it kinda reminds me of the old LTT videos... so maybe its not too bad :D
+Beef Ingot basically what cnet became!
+Beef Ingot yeah I admit this recording was definently rushed haha. Results and content was still interesting though
Using three-point or five-point lighting technique in order to get professional video is good. They only thing that this video lacks is they forgot to put less light on background. My two cents.
10/10 editing guys! "soTUNNEL BEar!"
Very informative and well done. The one consideration that I thought you would include is the CFM of the fans. CFM airflow determines how much air is being moved into the case (intake) or removed from the case (exhaust). I would think that a balanced CFM would be the goal of cooling the compartment. You want the intake and exhaust airflow to be near the same. There are cheap devices that measure airflow. I think they are called airspeed measurers. I would also advise using fans that are speed adjustable. This would help you to balance the case airflow. It's not all that important that you agree or disagree with me as long we both agree that warm air RISES.
that ending was hilarious.... that guy couldn't wait two seconds to let him finish signing off hahaha. what a tool.
i know right!
"They're kicking me out the door" :P
Adds to the humour. Brilliant
Hodor
It was poorly edited (only the end)
The golden rule?
Just put in as many fans as possible to make the system sound like an airplane, especially if you´re building a silent pc
+TheWuerstchenwasser Just add wings and you can fly away on it :3
Sawko
I agree with that :D
+Sawko Don't forget to fill your liquid cooler loop with RedBull xD
mohammed shahien
Go ahead :D
My Enthoo Luxe and its 7 fans sounds like a GE90 jet engine running at idle.... As an aero engineer, this pleases me greatly.
My approach to case fans (after 2 factory fitted ones included with the case failed) is. Buy a case without fans if possible, or remove if not. Buy some decent ones. Depending on how sensitive to noise and tone you are this can be quite in depth. Also pay attention to airflow (usually given in m³/h or cubic meters per hour) I'd say you want a minimum of 50m³/h for a 120 or 140 mm but higher is better, a high quality fan will get close to double this and should be much quieter. If you can live without LED's you'll often get a better quality fan (Corsair for one the AF 140 with LED's is lighter than the non LED variant) Pay attention to the bearing type, sleeve bearings are entry level, ball bearings are better. Personally I use Noctua fans. I use their Redux model for my case fans. Many cases can fit 3 X 120 mm fans in the front or 2 X 140 mm, here I would say it's marginally better to use 3 X 120 mm if this leaves no open spaces between the fans or case rather than 2 X 140 mm that leave gaps at the top and bottom. It also looks better aesthetically in my opinion. The airflow is similar for example 2x NF-P14 Redux PWM 1500 RPM move 267.4 m³/h compared to 3x NF-P12 Redux PWM 1300 RPM move 276.9 m³/h. The NF-P14 PWM 1500 is noticeably louder tho' @ 25.8 dB(A) compared to the NF-P12 PWM 1300 @ 19.8 dB(A) + 6db(A) is much louder, I believe we perceive sound as doubling for every +3db(A) These figures are obviously specific to these exact model types and other fans will vary wildly. If fan noise bothers you it is worth going into detail. Be Quiet fans are appropriately very quiet but they sacrifice RPM and by extension airflow to achieve this. Depending on how much heat your system generates these may be an excellent low noise solution but if your overclocked CPU and powerful GPU are working hard for long gaming sessions you may require more airflow. Fan placement is not as straightforward as you might think except for the obvious front to back flow. Top mounted fans while it would seem intuitive to have them exhausting hot air (I mean heat rises, right?) I was amazed to find that flipping them over and using them as intakes, I was able to knock 10°C off my VRM temps and a couple of degrees off my RAM temps without increasing any other temps. 10°C! That's a big reduction just for flipping your fans orientation. Bottom mounted fans, I would recommend some caution here, the last thing you want to do is to be sucking dust from underneath your PC and introducing it to the interior of your case. Unless you're struggling with high temps and you've no other options I would avoid bottom mounted fans unless used with filters. In general tho' unless you live in an extremely dusty environment I don't advise the use of mesh airfilters, especially if your case has a perforated panel in front of the fans. Adding that second layer of filtration absolutely kills the fans performance, far better to run without them and invest in an air duster and regularly give your case interior a blow out. The single most important factor when it comes to airflow management is the case. If you're running high performance components then the best approach is to choose a case which is designed to optimise airflow (Gamers Nexus channel has a comprehensive guide to help you choose a high airflow case) if however your PC is more modest then you can probably get away with choosing a case design purely on aesthetic grounds. Good luck with your build.
So weird to look back at these videos from around the time when I started watching LTT. Luke is in them and the content seems so unprepared and quickly put together. Also Nick doing simple tasks like getting some peripherals for the WAN show set instead of only sales is odd. Now there are people for the inventory and loads of writers to prepare everything for a video.
I miss Luke
I miss these old days. Scrolled to the comments to see if anyone else was feeling the nostalgia
@@elijohnson3090 samezees
These are so nostalgic, tbh its sometimes refreshing to see it a bit less prepered, there is a reason (except lasiness that @TechnologyConnections does no effort november).
Sidenote, tech has advanced so much in these 7 years that this production quality can perfectly be achived by 2 brothers, a phone and a decent pc
"lots of people freak out over fans"
being popular isn't easy :(
i want to see a follow up on how positive and negative air pressure affect cooling.
It doesn't really affect cooling but more dust goes into your case if you have positive air pressure.
Edit: Edited words.
I vent from positive to negative by changing the rear to exhaust and i get less dust.
Easy Skater pardon... negative means there is more air exiting the case and positive is when there is more air entering the case

Luké Ruké lol trust me you could, i plan to use an itx board for JUST the fan headers seeing as how 1 of them can lift off okay, so if you use a lightweight itx board, 3-4 fans, and than an extension cord (for the psu) it should be fine.

@@allipse8224 i love that album
@@mi-rek Didn't say "random access memory", he said "random random access memory".
the sentence aged like milk lel.
The pattern here seems to be that if an intake fan has a matching exhaust fan, it has a good effect on cooling, and front fans cool the gpu better (the lower the better maybe) and exhaust fans help cool the cpu better. You guys should repeat this test, but use AIO radiators of different sizes and mix and match the fans.
I always go for a positive pressure setup with inntake in the front and sometimes 1 in the bottom of the case if there's room and a filter that covers the position I want, then I go for a 2-3 exhaust fan setup in the roof of the case and 1 in the rear. This creates a front/bottom to back/top airflow with positive pressure, 4 inntake fans (+ PSU) and 3 exhaust fans.
I have 10 fans in my system. 2 front, 2 rear, 2 top, and 4 taped onto the window.

Why are computer temps the only thing in America measured in Celsius?
I'm going to assume that it'd just because it's a lot more widely used, and PC culture is a lot more widespread than other things worldwide.
That or other countries measured temps earlier than Americans
+Sunset Rider We are too lazy to change the software settings back to F'.
So we have to slowly learn things, all we really know is C stands for computer temps.
+Sunset Rider This show is in Canada.
Because Celsius is actually used in America quite often for accurate measurement and professional measuring.
+Sunset Rider Because people actually care about getting a logical, accurate reading.
so much efforts to put in to make a good benchmark videos like these. appreciate it..! and thanks you.
So funny to see how far the production quality has come 😄
Smoothest cut to the post ad so far.
that dude at the end of the clip seemed really passive aggressive
The total average delta T between the baseline configuration and the addition of more fans represents the total cooling capacity of the system. Due to the specific heat of air, it takes so many watts to raise a volume of air 1 degree C. Therefore going from the T4 CPU cooler alone to 1 front fan + 1 back fan represents adding 480W of cooling capacity. When you add the second front fan it goes up to 600W. Adding the next top fan gets you up to 720W and at that point you are removing heat way faster than your computer can produce it.
This test is really well done, very straightforward, insightful for sure
Maybe I'm stupid but a fan orientation might've made things a bit clearer.
Front fans are intake and Back fans are exhaust? How about the ones on top?
The top fans are most likely exhaust fans. Other two are just like you said.
Hey, when i was building my pc i made a quick search on it too, front are intakes, rear are exhausts, top is for exhausts too beacause the heat rises to the top so that makes sense.
Cant the top be used as intake and add fans at the bottom for exhaust (yes I know heat rises)? I know a person with a Haf X that does that.
You can do what you want. I have my front fan bringing it in, left side panel bringing it in, top fan bringing it in, and top exhausting it.

A discussion of case pressure - negative vs positive - & dust avoidance when equipping 1 or more intake fans with dust filters, might be a great topic, & it's related to this one.
Amazing tests, I always wondered about it.

+MightKeeper Yeah because the price of the case is going to be such an enormous variable in this test.
+MightKeeper if you're like me and like your stuff to match and be visually appealing( most cp builders like that idea) then you'll spend a minimum of $90 on a case.:)

Thanks UA-cam, I actually need this video today
I'm building my first PC struggling so much with all the cables but your video out of the others really helped me although wish you had better lighting would of made the process better.
I mean, this video is 7 years old. Maybe thats the reason for bad lightning :D
you shouldve tested a side panel fan and its effect on the gpu.
My strix 1070 idles at 33 degrees with a side intake fan and no gpu fans running.
Without it is 53 degrees so it's a huge difference at idle but under load it doesn't matter much at all.
Custom Zombies idle Temps mean nothing. I've personally tested my HAF 932 and the side panel fan made very little difference on my gpu Temps but surprisingly dropped my cpu load Temps by about 3 Celsius. if you have a gpu with a good cooler like the wind force 3x case fans don't make much of a difference gpu wise.
My 780 ti idles at 32 when ambient is 36 xD
980 idling at 38 with a Corsair H90 AIO, but at 1525mhz and 1.275V XD
yea im gonna put in a side intake fan on my rig, its an 80mm antec with blue led and 3 speeds, hope it turns out good!!
I disagree with you, it's not that more fans is a diminishing return, it's that when you increase the internal pressure by installing more fans it will need to be balanced. You need to tune the individual fan speeds to create an optimal pressure and flow pattern. Try using a fan controller and smoke to balance the flow pattern, then use a photohelic or a manometer etc. to set your case pressure. You may need to tape off case vents (since no pc cases on the market have flow gates that I know of) to achieve a good balance. That's how to make the fans do their job and give you the biggest bang for your buck.
I've worked in the Semiconductor cleanroom industry for 30+ years, I know this topic well.
K.
Can you shorten it Down
I get the feeling that the equipment needed to measure the flow as perfectly as described probably costs 4k$ or even more.
@@JoelHernandez-tz3vk I just use a vape so I can visible see how the air moves
@@jaspervn4722 I think I saw jayztwocents using incense for this process, wonder if this is accurate enough for most people.
I know it's 7 years old, but I wanna point out the thing this video missed: *Noise levels.* He focused only on temps, which isn't the primary reason for loading up a bunch of fans. A couple of fans can run fast and blow a lot of air, but it's noisy. If you have many fans, you can run them slower to move the same amount of air, making the PC *much* quieter.
The whole time, even before watching the video, I had one fan configuration in mind that I was curious about. But due to the design of the case, this wasn't something that you could test. I was curious if you had a top vent/exhaust/intake, would a) two fans as intake, b) two fans as exhaust, or c) one push and the other pull (perhaps swapping as well) result in better thermals? Otherwise the rest of your setup is indicative of my own. And what about lowering fan speeds with more to be quiet (obviously many more variables and hard to fully test). Awesome as usual and thanks!
Actually really digging this kinda video Luke. It's relevant for the consumer and viewer instead of the 4 TitanX black benchmarks. It's interesting to watch. Easy to play around with even if the viewer is the avg John Doe fiddling with his PC and will give huge improvements over the usual craycray stuff that gives a 0.1% improvement for a loooot of work. So thumbs up on the idea for this video. Really enjoyed watching it even for a tech veteran.
er, the '2 in the front' the added second fan is blowing 90% into the PSU enclosure lol
Just ordered 2 more fans because of this video. Small fan for top and back and big fans for front. Trying to create positive pressure to minimize dust all while keeping my Pc as cool as I can.
The test would be more interesting by adding some fans to the sides! 😀
One thing not mentioned...Using a variable speed (PWM) fan array: more fans @ lower RPM make less noise than fewer fans @ higher RPM. So, if noise is a concern for you, keep this in mind.
Would've been interesting if you also switched between all intake, all exhaust, and push/pull.
I'd like to see comparisons between having only exhaust fans vs intake and exhaust fans. for example; 2 exhaust (back and top) only vs. 1 back exhaust and 1 front intake. Also would like to see comparison using same fan config and components in a smaller mid tower vs that giant full tower, and maybe even a mini ATX tower.
Why am I addicted to videos that Luke is in?
Fans are blowing in or out? How do you forget to tell us that?
Marc Marc in more than out is always better
Usually, front fans are pulling fresh air in, top and rear fans are pushing hot air out. I think he did this way ;)
Why the hell is it not obvious to you? Top and front are intake and rear fans are exhaust.
The norm is rear & top are exhaust (heat rises) & front is intake... Centiliter is trying to troll you.
Tim Beals he's actually right. It's not fair to call him a troll. Some cases have the top configured for an intake. Such is the case with my, well, case. It has a removable dust filter on the top. I can configure it as an intake or exhaust as I see fit. Though in most cases, this isn't the case. You are also correct. Most cases use the top vent as an exhaust. The whole "heat rises" thing doesn't have much of an effect in the case as per Linus. I would assume it's because the air is moving fast and in a small space that it doesn't rise much.
Edit: my case also has a side vent with no dust filter. Thought my cpu cooler fan seems to be an intake rather than a exhaust. Some cases are built with a different setup in mind.
you did not test push, pull, that also makes a huge difference, pulling the heat out or blowing cool air in
I was thinking the same thing. Also he never said whether the fans on the top of the case where intake or exhaust.
i found making them "intake" is a big NO NO, cause it sucks in all the dust that falls on top of the case, but it should be intakes for this reason alone ,water cooling, all the hot air from CPU is going up into the water cooler(if you do have a water cooler) and so the top fans should not suck in that hot air through the water cooler
+drink15 uhm fans is for airflow, comes down to what airflow you get from how much fans you put in
+drink15 was not arguing wat the video was about, just trying to give advice on future videos he would make, think of all the agles
I would like to see luke or linus do a video on Teraflops on GPUs and why the AMD R9 480 has 5.5 Teraflops but is still significantly slower then the Gtx1060 with only 4.4 Teraflops.
Wow, I actually understood the benchmarks in this video, lol. When others start comparing CPU clock speeds and such, I'm clueless as I'm thinking, "Does it really matter if it's 2 milliseconds faster?" But here I can understand why you'd want the CPU a few degrees cooler.
Looks like I had my fans set up for the best performance the whole time. 2 in the front, one in the back and one on the top
Cool ^^ Hmm, making me rethink buying 2 fans to install in the front of my case rather than 1 fan. The Cooler Master Q300L case only comes with 1 pre-installed rear fan.
You can buy 4pack fans fr cooler master, its cheap
You definitely need more than the one for that case. The reviews are very critical of its airflow.
I have the same case. What did you end up going with and how did it work it out?
I have this exact case and I have been trying to figure out the best fan set up. I have two intakes at the front and 1 exhaust, but I am debating installing one more intake or exhaust
I had 2 on the front wall and 3 on the top of the case.
The cooler: Wraith Prism.
Idle temp (3800X): around 50-55C
Load max temp around 80C
Chipset temp: 60-65C
Then I replaced the Wraith Prism with NH-D15S and surprisingly the temps didn't change at all. After several hours of trying to fix it I decided to see what happens if I remove the three top fans and add one on the back wall. It was a huge surprise to see the temps afterwards. CPU idle temp now 36-42C and max load temp when doing normal stuff 58C. Chipset temp 51-56C. The three top fans messed up the airflow that badly. Also now my PC is very silent.
I always looked out to get the most amount of fans in my system while caring for a good airflow. Front bottom as intake and rear/top as exhaust works usually very great. But fans in the side panel are often times counter productive for that kind of airflow, so I use them.
My last PC was pretty much the only one, where I ditched my usual airflow build since it's build in a "Tacens aluminium extreme" case which got an insane 40cm intake-fan in... or rather AS the side panel. This baby spins at only 800rpm and while completely silent it just pushes around 250 cfm of air in the case. Used it as only case fan and with the silent "Arctic Cooling Freezer Xtreme Rev. 2" on a Phenom II X6 945T and a Gigabyte GTX 960 4GB with dual-fan design, that system was basically completely silent & cool. Still runs today like a charm ;D
Great video, thanks for posting. I just swapped out the 3(120's) fans that came with the case and added one extra to the top(140's). Seems like I'm bring in more from the front but the top one isn't extracting much. I still have one more for the top and them I guess I'll have to dial them in..
Cheers
My ceiling fan will do.
"How many fans should you have?" Short answer: All of the fans.
this gradual approach was great
Excelent video! I cant find any better nowadays
THANK YOU : very clear and interesting vidz !!! thx from France !
Very clear? I would have appreciated him explaining which one's intake and which ones are facing out
I just moved my GPU from vertical mount with PCI extender cable back to board mount and temperature dropped from 72C to 62C. When vertically mounted it was pretty close to the glass so that's probably why. Plus the PCI extender cable adds a touch of lag to the GPU so also better board mounted.
I have a filter on top of the case for mounting the water cooling radiator with its two exhaust fans, and only one other fan. I'm currently using it as exhaust on the back, but you've convinced me to try it in the front, lower, as intake. My other option was to mount the radiator as intake in the front, but I was thinking it would just blow warm air in so I skipped that. Warm air would still excape through the filter on top and through the back fan hole, of course (my PSU is encased in the bottom). Of course, adding more fans is a good idea according to this video so I'm going to do that. Maybe I'll also run a milder benchmark too and return with results. I know it's old, but thanks for the video - it's helpful / informative.
I think you’re seeing diminishing returns due to excess air pressure. Your 1 exhaust fan is bottlenecking your 4 intake fans. You could possibly further increase cooling possibilities by adding bottom mounted exhaust fans, turning one of the top fans around, or using an exhaust fan that’s much stronger than the intake fans
Yeah. Once again, a place where tilting the computer on the side would probably help some if it has fans bellow the MOBO or close to it not getting the turblance and convections effect vertial towers create. Titlt the whole fucking thing on the side kind of like an Xbox or something and then you work better with physics, at least for fans colder heavy air tending to cockblock the hot air...it'd seem like you'd get a little better improvment.
Pluse you get a preemo monitor stand to boot.
@@gorkskoal9315 That's very interesting. Could you expand on the idea ? Why would a tower build work against physic, compared to tilting it ?
If you look closely, he actually adds exhaust fans on the top. So with 2 front, 1 rear and 1 top, it is in fact equalized, and slightly negative with the final config.
@@Syldar well the positive pressure is better so he should have thought about doing this experiment with negative and positive pressures with all the different fan variations.
Should've put a couple spinning HDDs in there to monitor those temps under load as well. I always make sure at least one fan is blowing on my HDDs as well to protect them during those hours-long copy operations.
the Asus company says they get their name from PegASUS...Pegasus...shouldn't the name be pronounced like the tail end of Pegasus, not like the mexican version of Jesus?
Thanks for the tip. When I heard him I was wondering if I've been saying it wrong my whole life.
Some ppl say it Ayy Zeus while others say asus as in pegasus so idk
No difference whatsoever. It’s English, however he pronounces it it’s wrong.
I've always said it as "Eh-sis". But that's just me.. and because i want to watch the world burn. 🤷♂️
The german pronounciation for example would be exactly like in "pegasus". i've said it right my whole life :D
im such a big "fan" of ur channel ;)
haha..
+SMURF oKING heh
nah ill stay
+SMURF oKING LMAO I loved this one m8
Nailed it! xD
I just got my new case and it only came with 1 fan, good thing I decided to watch this.
In the beginning, my eyes were messing with me because that lighting makes you look like an animated cardboard cutout! I'm not hating, just found it entertaining :) Thanks for the video!
