Could you do a Pull vs Push-Pull comparison?
Edit: Didn't watch the entire vid, sorry.
Doughnut already been done
+RidiculuzPrime have a link? Everything I found was just talk with no evidence
+Doughnut the delta between the two is marginal at best
Doughnut again?
You didn't watch the video did you :)
What about balanced fans
Wow this is my first time seeing a big youtuber commenting and got no likes
Here's a like, buddy
@@juparkjr1285 this was back then when he didnt have many subs lmao and its cool seeing him here 😂
@@babyyoda3828 right...
Lol..
didnt expect to see you here
Speaking of pc parts, how's Terry Crews comp coming along
Aku Chan in a recent periscope he mentioned that he won't be doing anything with that until after the holidays
That's not soon enough >~<
Jkjk
Thanks, I should pay more attention to other things I suppose
you didnt know, not your fault
It's cool, I'll just sit at top comment
In his last tech talk he mentioned he now has the parts... not much else though
JAY I'VE BEEN RANDOMLY UNSUBBED FROM YOU TWICE NOW LMAO
David me too
same...
Same here..
Don't worry. UA-cam keeps saying NOTHING IS WRONG! No wonder UA-camrs are complaining about random sub drops.
UA-cam IS BROKEN!
THE WORLD IS ENDING!!!
"I'm going to get to the point..."
2 minutes later: still hasn't started. lol
How to spot a USA youtuber.
Paused at 0:00 to finish listening to something before watching, and the freeze frame of Jayz face was absolutely priceless.
Well at least you have lots of fans now!
Lol
I like the consistency with your channel, non of that random of topic stuff like a lot of of other channels. Plus the quality of your work is a lot better than most other people. Your videos do help me out when it comes to informed buying decisions. I do recommend this channel to anyone who wants to learn more about computer components. Keep up the good work man.
P.S. Your videos are a lot more interesting than most others.
The fans keep asking for videos about fans.
That's "fan"tastic.
FANtastic would be a good case fan company name
The rather interesting thing about this test are the specifications on the fans. The AF120 QE pushes 38 CFM at only .5 mmH2O. The SP120 QE also pushes 38 CFM, but at 1.29 mmH2O, comparable to a lot of other 120mm case fans. So better static pressure makes a difference, but the gain appears insignificant: over 2.5x the static pressure, only 5C reduction in temperature in the test. I wonder how much of a temperature reduction you'd get going with the SP120 HPE, which pushes 62 CFM at 3.1 mmH2O (but also 35 dB/A, yikes!).
Another test would be pairing two fans of the same static pressure but different airflow ratings to see how much of a difference the greater airflow makes. There are plenty of fans that are similar to the SP120 QE on static pressure while providing better airflow. The Bitfenix Spectre Pro, for example, is similarly rated to the SP120QE on static pressure, but pushes 56 CFM. The Nanoxia Deep Silence 120mm (1300RPM) can push 60 CFM while running at only 14.2 dB/A and is also similarly rated to the SP120QE on static pressure.
But but but Jay... You OBVIOUSLY need static pressure fans... Don't you KNOW, otherwise you're radiator will melt!
This is a great video, I really liked how the video was made into a relatively brief vid. Excellent work Jay!
I used to be a fan...
Now I'm an AC.
TehObLiVioUs old joke already herd it
Artistry Minds Sorry couldn't think of anything more clever at the moment.
TehObLiVioUs I used to be a fan... Now I'm liquid cooled.
HERD? Xd COME PLAY ROBLOX WITH ME GUYS SNORK
Oh my god...
Its always good to see the basics for folks that may have questions.
We don't need AF fans the eye can only see SP fans :/
Obviously you don't having gaming glasses. I can see up to 7 AF fans with gaming glasses at 20C room temp and 1.35V
I put my computer in water and it doesnt work now. :/
@@DannyGruesome bro 💀
Don't forget that fin density will make a difference too. In this test you used a fairly dense radiator. With less fins per inch the difference between fan types would be less as there is less resistance. In fact, it would be interesting to see that experiment as with less resistance you would expect the AF fans to do better. Next video perhaps Jay?
dude, u love cars and computers. U ARE MY fav UA-camr!!!!!
Hell yeah man. This guy is the reason I gave up console gaming and got into PC.
i love cars
This is the only video, I've found on YT that actually does test the performance difference on a radiator, between a pressure optimized fan and an airflow fan. And the result is really what I've expected in terms of difference. And just like Jay have said in the video: you don't have to have Noctua NF-F12 or Corsair SP-120 fans for radiators. Although I have Noctuas in one of my rigs. I've actually been using Noisblocker Blacksilent Pro PL-2 fans in my main rig for 7 years now. I mean they are 7 years old and still as good as new. They aren't really optimized for one or the other. Just a very good overall performance, all black, dead silent and start and run at 4.5V (unlike my Noctua NF-P12).
So if one doesn't like the Noctua looks, or bored of Corsair, there are fans out there, you can buy instead. Not all of them are good, but you can find good ones. I'm just starting to buy some BeQuiet fans to try them out. They look promising, from what I've seen and heard from them. But I still love my NBs. :)
Great video btw, Jay!
Geniuses tend to procrastinate
I bought the FTW Hybrid based on your review of it, set it up with a push/pull based on your other video. I also set up my front H100i in push pull as well. All are SP fans. Great info for keeping my case as cool as possible.
NEW Question : In push pull what is the difference between SP push & SP Pull or SP push & AF pull or AF push & SP Pull ?? :D
id imagine the best configuration would be AF for pull and SP for push
@@thepersonguy1192 SP fans build pressure in the push configuration not pull
@@cbrunnem6102 sorry, i meant the other way around. its fixed now.
Wow. Only about 2 hours ago i finished my build, with THAT GPU, and questioned using a pair of AF120s i purchased, forgetting they were to go on a radiator. In my case, they were going to go on an H100i v2. A quick google and i learned the difference between SP and AF. So naturally I decided against it and went with the fans that came with the cooler, forgoing the cool lighting. I mean, what would the neighbors think? The results surely would have been catastrophic. And now, I hop on UA-cam, on my new rig, and Jay drops some knowledge on me outta nowhere. Tomorrow, the AFs go on. On a liquid cooled setup, what's 5 degrees? Thanks for putting my mind at ease Jay.
Jay, my man... haven't watched your channel in a minute. You look great, dude... congratulations on the weight loss.
xSirDingo Probably typo
You guys are idiots. It's a figure of speech.
Really, the determining factor of the performance of high air flow (HAF) and static air pressure (SAP) differences is, the thickness and the fin density of the radiator. Cheap single layer AIOs won't benefit as much from a SAP fan, but double thickness ones or higher fin density ones will benefit greatly from SAP.
This is what I've discovered from tinkering with a 120mm double thickness AIO, a 240mm single thickness AIO, and a 360mm high fin density custom radiator. However not a true test thanks to different radiator sizes.
Love the attention to detail in this video especially with the visuals. Great work.
I'm going to install my ceiling fan to keep the temperature under 5 degree on AMD Zen
vishal Sharma lool 5 degrees above boiling point of water because amd zen will run at 2V!
higher voltage doesnt always mean higher temps if you're not talking about the same architecture. It's about the tdp. AMD already stated that their tdp's would go down a lot. i'm an intel user myself, but if amd is right then the competition will be on again
We'll see. If it was 2v though, that is insane for a cpu (atleast if it's not nitrogen cooled). It will have a high tdp if it is 2v.
Abhinav Praveen there's no correlation between voltage and wattage without knowing how many amps go through the chip. if the voltage doubles and the amps half, the wattage is constant. if the new amd chips have a higher resistance than intel then amd could very well hit 65 watts tdp on the non oc ones
Youri Dv If the amps half and voltage doubles, resistance would increase, and each resistor generates heat. That will also decreasw efficiency increasing wattage either way.
What about push/pull delta using all SP fans, and 1 SP/1 AF?
Haha... you would hear only fans not the game sounds...
I have a 420mm rad in the front in push pull. Push fans are EK static press and pull is Corsair air flow. Idea was to push alot of air through the rad then the flow fans to spread out the air. Should I rather put static pressure in pull as well?
Hi Jay, can you do this same test with Corsair's Magnetic Levitation fan? Thx.
Thank you for the early video. Wasn't expecting it till tomorrow. I've going with a 480 rad with push/pull using 120 Vardar FF5s. They've been shipped out and should all be here in the next few days. Wouldn't have known about Vardar or PETG or anything nearly as much without your videos. Thank you for the knowledge you pass on and also the random stuff you and Coconut Monkey come up with.
Am I the only one going crazy trying to figure out where the hell he's linking this supposed push/pull comparison video?
Can someone link me it??
A year later. ua-cam.com/video/IJmE13sG9PI/v-deo.html
for all the goofy little "full of fails" this video had, it was EXTREMELY GOOD. keep up the good work!!!!
I'd be interesting to watch this same experiment be done in a CPU tower
The most important thing that your audience needs to know is that the CFM advantage of an airflow fan is going to be completely negated by any amount of static pressure and there is very few situations that do not require static pressure (like an open air test bench). In an average case static pressure fans are going to move so much more CFM than airflow fans will because of the static pressure in the average case (even high end). JUST BUY STATIC PRESSURE FANS ALWAYS.
Here's the thing about running airflow fans as case fans. If you have a restrictive filter on the front of your case and the airflow fan does not have enough static pressure to overcome the filter it will not pull in air through the filter.
I did this test with a Fractal Define S and Fractal HF 14. The fan was recirculating air inside the filter and could not pull in air through the filter(there was no way that I could completely seal the area). I put in a Fractal HP 14 (static pressure fan) and noticed how much air it moved through the filter.
I also did thermal testing with various fans on my case in different configurations. Static pressure fans dropped my gpu temps by 10-20c compared to airflow fans.
Radiators are much more forgiving than some good case filters because they don't require a static pressure level to overcome. This can be partly attributed to the air seal that the radiator gives to the fan itself.
This test was also done using lower rpm fans on a thin radiator which doesn't require a large amount of static pressure, yet there was an obvious difference. There was also no baseline recorded with no fan on the radiator too.
I love you Jay but, you should check out the testing methodology done by Thermal Bench and possibly Gamer's Nexus. Now I do agree with the conclusion that you came to that airflow fans are okay for a 120mm radiator but, I really strongly disagree that it sends the message that static pressure fans just give you a few extra degrees of cooling. Please make sure your fans know that they should be buying static pressure fans for almost every single situation or they are losing performance period. You don't run an i3 with a 1050ti because your setup has more performance. Don't run airflow fans when static pressure fans cost the same and give better performance. There is so much data to back this up.
new name suggestion jayzabitwit
LinusSexTips
TheWarewolf911 yeah compensators 3
My radiators which are Nemesis Black Ice(yeah...I know...) are making an acrid smell and are using TT Riings which are custom PWM versions but I believe are airflow fans. The company who makes the Rads claim it is a solvent issue under the paint on the rad but I wonder if they are overheating because of the fans I am using. I should have went with EK or XSPC rad and EK Vardars SP fans.
This is my favorite channel because your test methodology follows the scientific method to the letter.
AF fans are bad AF (see what I did) this is a bad joke
Phillip truong
Well, If you had an open case, using a High Airflow Fan would we way better than a SP fan... So for a case fan AF fans are lit AF
whoosh
yourcurtainsareugly Whoosh
Edited comments strike again
I think I have a good question. Not sure if you'll be able to test it, Jay, but AF fans push air throughout the entire surface of the fan, while the SP fans usually push a lot of air through the centre of the fan which can disrupt air movement inside a case.
So to the question. Would putting an SP fan in a push configuration and an AF fan in a pull configuration on a radiator work well for cooling the radiator while maintaining low noise, low RPM and and an even airflow?
- High pressure
- High volume
- Low noise
- Low cost Pick any two.
JayceStardasher low noise high pressure
or pick 3 with the 4th being the opposite of what one would want for example: noctua HIGH cost, high pressure high volume, low noise...
although i suppose we could talk about a 5th choice - aesthetics
I have to agree with Jon on this one. There are several available that do at least three of those without a doubt. An example would be the LEPA LP-BOL12R rated at a high 81.5CFM and a quiet 18dB while only costing $12. And I'm sure if you looked hard enough you'd be able to find a fan with good airflow, good pressure, low noise, and low cost.
First 2. I'm all about performance over aesthetic and noise, which come second.
This "high pressure" of Corsair SP is Cute :)
I will pick three : 1-st, second, and fourth :
Why ?
Because ebay.com and Delta AFB1212SH (113CFM/10,9mm H2O) :D
Great video Jay. Sometimes, videos like this can get drawn out and boring but you hit the sweet spot with this one. Good job.
Next is push-pull configuration :D
DARKRENGIN PRODT. It you watch to the end he says he's done that video
Ikr but we need a newer one :D
...it's recent...
but why its been done and it's only a few months old.
DARKRENGIN PRODT. the time when it was done will not change the outcome. 100 years ago if you fell off a building you hit the ground, same holds true today.
Ive needed this video for a few weeks now! Thank you! Keep up the great work Jay
i use which ever cheapass fans that work
Leon lol
that's the spirit! but don't combine that with AMD plz
Good video, I know im being one of those people but I would have liked to see the test with different radiators. See the problem with this test is that its a slim, likely less dense fpi whereas using a thick, dense fpi would see a larger gain from static pressure optimization as well higher speeds. A perfect example is the ekwb coolstream thin fans... The SE I believe? They work great with either fan type. Use a thick hardware labs and see what happens.
Jay shows the haters science again.
Very good test Jay, I have mixed fans on my setup and I always wandered how much it would improve if I had the proper fans. Looks like it's not worth bothering.
i dont even kno what static pressure is....
really?
static pressure fans are for obstacles such as radiators or cpu cooler fins. High airflow fans are for open environment best suites as case fans. Now I am writing this before I see this video so who knows, but thats what they are intended for :P
RusoGTR yea never heard of it before
static pressure means that the airflow is limited between a certain space such as a fan and a radiator, there's not much airflow available, that's why there are fans designed for static pressure.
What ? No. When the "airflow is limited", we talk about pressure drop. Static pressure is what it is, just a pressure. When a fan is optimised for static pressure, it only means that it converts a higher percentage of given power to pressure and less, since power is conserved, to air flow.
There is so much miss information in water cooling. So many people on forums telling people what to do and they don't even know. Fans, radiator thickness, what coolant you use won't effect temps that much. Pick fans based off sound and looks.
Love the generic title :D
Nice vid Jay i really like this kind of "myth breaker" video, and i really appreciated that this one has not a single chart.
Maybe we are moving little by little from charts in the future?
Just a feedback.
(personal maybe? someone can tell me if i are one of the few people who prefer to see the raw data and how those data are tested, is way more interesting than see a chart only, even tho the process to get there is almost the same).
Are you psychic? I was literally searching for a video on this today.
Thanks for doing this test and showing data. Was thinking about getting good SP fans for my 120mm rad.
the video starts at 69:59
Great comparison Jay, puts the debate in perspective. I was hoping for a high school lesson on error bars! :)
I lolled completely when you hit the mic, and again when you almost hit it again. Love it when you leave the fails in! :'-D
I prefer this kind of short videos. More entertaining than long ones.
I'm Rick Harrison and this is my pawn shop. I work here with my old man and my son, Big Hoss. Everything in here has a story and a price. One thing I've learned after 21 years - you never know WHAT is gonna come through that door.
Holy bananas, I got so frickin scared when you hit the mic with the cable... Love that you keep some fails in your videos, good stuff!
Jay, you could probably make a video about anything and I'd still enjoy watching it. I also don't skip your ads :)
id be interested if you ran the same test also comparing not just static vs AF, but also push vs pull
Admit It Jay Is the Most Entertaining Tech UA-camr Ever!!!!!!!!!!😃😃😀😀
Great video. The paper on the rad is a nice tell all.
There's one thing that haven't being tested is the push or pull on a case between a pressure fan vs a airflow fan.
I'm pretty sure that a pressure fan work much better for negative pressure in a case & using a airflow fan work better at positive pressure.
So I have a high supposition that a pressure fan is a must for output air & airflow for input. I also believe that if you only use airflow fan or only use pressure fan on a case it negate the best out of it.
interesting test. It's good to see the actual results support the argument for having specific fans for specific things
Jay should do a video of full watercooling system maintenance (cleaning the blocks inside and such) and also adding new components like motherboard and such and, if you need to strip apart your loop.
Could you do a comparison on AIO radiator orientation and its affects on temperature, and noise?
I know AIO coolers aren't filled to the brim with liquid to allow for metal expansion, and I have read, and think, that having the inlet/outlet ports on the top can affect temperature and mainly pump noise, but it'd be nice to have some actual testing done.
thanks for the demo Jay. love to see these videos. silent majority stand up!
Much needed video, well done. I wonder how much worse it gets putting a dust filter in there as well.
One thing overlooked in this test - It stands to reason that the more resistance in the set-up, the larger the delta would be right? A SP fan would handle more resistance than an AF fan right? So if you threw a thick mesh fan filter in front of that rad or put it in a case like the Phanteks P400 or the NZXT S340 where the air is being pulled in two small vents at the top and bottom of the front panel, would you not expect the delta to be a wider spread? And of course, thicker radiators would also have this effect. Amiright?
Jay, while I definitely understand the difference for rads between SP and AF fans, would you recommend using SP fans for cases that have very little space in front? IE: the Corsair 750D (Non-Airflow edition) or even a lot of the tempered glass cases that only allow air in from the sides of the front (If that makes any sense)
New video topic idea? Testing cases with AF vs SF and what it does to temps?
If Jay keeps this up the internet info will be more correct,
Such badass >u>
Thanks for the video Jay! I can't recall seeing a direct SP vs AF comparison (usually just talking about it), so an actual test as nice to see.
Thanks for the great video J. Now I am not so freaked out about the fans I'm going to put into my new 750d case.
240mm Rad w/noctua SP 3K RPM fans. Inside a case I made (imagine a DAN Case ff but windowed) w/ CPU+GPU water cooled loop.
plus modded PSU fan for further case cooling with the addition
of two more 120mm AF fans. Just a tad bigger than a shoe box weighing in at +20lbs
Wow! I didn't think it would make THAT much of a difference. Great video as always Jay.
Noones done a test for static vs AF for pulling force (induction side) of the fan. For pull through setups
I would love to see a review of fans with cost vs noise vs performance for radiators. Need some fans for my custom water cooling setup.
Not sure if this has been answered but which combination of these should we use for push pull? Should it be airflow exhaust pressure intake? Should they both be pressure? Does it make any difference?
hey jayz have you tried comparing the two in a pull setup? what will be their temps?technically sp are designed to push air through obstacles while af are designed to push high volume of air..
I got a 120mm radiator (54mm thick) with a Vega 64. I saw that it's supposed to be rated for 400w, but i am thermal throttling. Hard. Even after undevolt. This video showed me that the issue could be the HA-fan I have on it is probably not pushing enough air out.
I personally would still recommend SP fans. My result was with my 2 360mm rads, I used 6 chinese really low pressure airflow fans and the temps were about the same as 4 SP on the same radiators while being audibly louder.
Airflow fans: Aigo Dr12 Pro RGB
Static pressure fans: Arctic P12 PWM PST
In the end, the cost is about the same when comparing single fan prices. RGB and no Pressure resulting in higher temps or higher noise or black fans with good pressure and lower operating noise and thermals. If you don't care about performance, you could go for airflow RGB fans and simply let the system run hotter(while remaining within safe temps). I personally prefer the blacked out look in my build and the nearly silent operation while under heaby load and gaming. My noise bottleneck are my 3 HDDs and their 40mm cooling fan. The rest is more silent
Hey Jay can you make a 550 dollar gaming pc build guide for the holidays and possibly a benchmark video after that? I would really appreciate it keep up the good work!
Thanks for leaving the little bloopers in the video!
thanks for this video Jay! I'm planning on upgrading my fans and wasn't really sure what difference it would make between them. this helped a lot.
ive watched most of your videos but i can't remember, was there a video comparison between a full case layout with sp vs af with no radiators? i assume most people watching don't have any radiators on their videocards or cpus and so it would be a bit more applicable to most viewers. perhaps even on an mitx case like a fractal core 500. get fractal josh to send you two cases so you can run both at the same time, to maybe help with changes in ambient temperature a little
Hey jay, I'm really new to the computer hardware stuff and was wondering if you could do a beginner guide to computer hardware. I keep hearing all of these letters and number for things and i really don't know if they are better then others or not. Thanks for the vids and keep up the good work, love learning all this new stuff.
I didn't think there would be a difference between the two type of fans. very interesting video Jay!
Thanks Jay for this informative video as always from yourself. cool you left in the part where you caught mic with fan cable adds a light hearted chuckles time.
Hey Jay, nice vid once again, the piece of paper was a nice idea. Could you maybe in the future try this test again with the radiator mounted inside a closed case to see how the lack of static pressure would affect the case's internal temperature? I'd also think that the fan grille would also add some resistance, would like to find out. Keep up the good work
Jay what if you did SP for air entering the radiator, and then AF for pulling air away from the rad. Basically Push-pull with SP for rad intake, and AF for rad exhaust.
I really like your videos but I think you should have used good radiator fans like the noctua NF-F12. (don't even know if youll read this..). But for starters the SP quiet edition from corsair are crap and only produce 1.29mmH2O of static pressure. There are two AF (one that produces 1.1 and other that produces 0.5mmH2O). So basically this would perform very similar. Now if you compare this to the corsair SP high performance edition which produces 3.1mmH2O of static pressure or noctua NF-F12, then there will be a difference. I do agree that if someone bought the wrong fans its not going to burn your system down......
Anyways keep doing a great job!
Thanks Jay, this will help people just starting out alot.
Jay - Now how about a video on customizing AIO water coolers. Like with the EK Predator, replacing stock fittings with maybe 45degreee swivel, shortening hoses or replacing hoses with shorter length, etc???
John
Thanks.
You should have also compared them at the same air output (lower rpm of HP fan such that both move the stick to the same angle). Then check for cooling temp and noise output.
Also an idea, try something in a case, like are air flow fans are useful in cases, without water cooling, fans just as intake or exhaust fans
Your videos lately have been totally kick ass. Keep up the great content man!
I expected a much greater difference to be honest. It wasnt that far off each other. Nice video. btw congrats with misses jayztwocents
videos are well informed, and at times funny, keep up the great work Jay
Great content, like everytime. One of the best Hardware and PC based Channels on UA-cam, thanks Jay!
Could you do a part 2 inside of a case instead of a test bench?
Hey! I've been an avid follower of your channel. You've been doing great work. Godspeed to 1 million subscribers. Cheers👍
