***** Hello Jay :). I have a Fractal Design Arc Midi R2 and I'm going to buy new front fans. My bottom hdd cage is full and the upper one is removed. So if I get your info right I should go for a SP140 in the lower front intake and a AF140 in the upper front intake? :-) Or should I just go straight SP140's in the front :-). Going for white led version to match my white build :-).

[@sreekumarUSA]

Greetings from California. This is very informative and Thanks. I had an issue for several days, with over heating Bridge and Mains Power supply Transformer on my Yaesu FGR7700. This is a Communications Receiver. But dissipating Heat is common to all devices, I’m sure you are with me. So, I tried Heat sink and it workers satisfactorily .. I’m all smiles Yo. I beat the heat! So closed the bottom cover and switched ON. 20 minutes later The receiver power supply area got tremendously hot to touch. AIR AIR... need Air says the Receiver. So, now what? Removed all the cumbersome heavy heat sinks, and fitted AAVID 50mm*50mm ball bearing fan ran the device. Cool.. system ran cool. Proud to have redesigned a system. Closed the bottom cover. Switched on and AGAIN . 20 minutes later The receiver got hot as before !! What The $#$@@ ! Removed the cover and I realized that the space between the fan intake and the Cover was jus over 2mm !!!! There was no Air Pressure ! Fan was spinning with no air movement due to almost blocked intake. I relocated the fan, to an area of free flow and pressure. Put the cover on... Fingers crossed... 20 mts later , 40 mts later 60 mts later NO HEAT ! I was substantiating your theory. Thanks buddy. Stay safe. 73s

[@sulinsugathan7188]

hi, I've a full tower case and there is a dust filter in-front of the fans. I want to change them, so should i go for static or airflow?

[@Diamondviper911]

Best video I could find explaining static pressure vs air flow. Thank you!

[@theentertainer1097]

Nice explanation! I have a question, regarding static pressure. It's perfecly clear now, that if you want to use a radiator in a "push" configuration, you need a SP optimized fan, because it's more capable of pushing air throughout the tiny cavities of the radiator. My question is about the "pull" configuration: what about the static pressure that is generated BEHIND the fan? If you use a fan in a PULL configuration, the air is "pulled" within the radiator from the rear part of the fan and since an AF-optimized fan moves "more air", shouldn't it be more effective than an SP fan?

[@Thiccyg]

Let me know if you discovered which type is better to put on either side of the radiator. Looking at mountjng fans on both sides of my front panel radiator and am trying to find this too

[@drbalaclava]

The static pressure fan makes the same pressure in push or pull when mounted on a radiator. The radiator makes the same resistance both ways

[@richardveljkovic5526]

EK Vardar Furious, for an example, as SP fan is a bit better in pull than in push (as stated by EK on their website). But anyway, always use SP on radiators.

[@priyanks5651]

The gift that keeps on giving. JayzTwoCents to the rescue!!

[@Gohrek]

Very helpful video, thank you. I admit, I know very little about fans in general, but I know for a fact that when I'm in need of one, I always choose Noctua, since I always hear they're the best when it comes to fans, and I've yet to have one fail on me. Subscribed.

[@noahsworldonline]

Hey, I'm currently working on my first computer, and I plan to replace the stock fans in the case I have. I'm going with Jay's advice and using an AF120 for exhaust and SP 120 for front intake, but I would also like to populate the two fan slots on the top and the extra on the bottom, by the power supply. Here's where I get confused; should I use airflow or static pressure on the top? Should the top be taking in air and the bottom exhausting? If so, should I use an SP fan on the bottom to overcome the somewhat small gap between the case and the floor?

[@noahsworldonline]

Thanks for your input! After doing some more research and reading your comment, I've come to the conclusion of dual SP front intake (air has to make it through the drive cages), AF bottom intake (case will be on wood desk), AF rear exhaust, and perhaps AF top exhaust, but natural convection should be alright for now. What do you think?

[@verisimilitudeteller]

***** I have airflow fans on the front of my case in spite of it being adjacent to the air filter, I did remove the hard drive cages and relocate my drives to the unused 5.25" optical bays, so the air flows right into the case, directly at the underside of my GPU. I don't think the air filter gives enough resistance to justify using sp fans, but I guess it depends on the type of filter you're using, I've seen people cut white fish tank filter material thinly to use as an air filter on their case. My case came with the magnetic type filters so I'm not sweating it really. I could be wrong and if I am I'm open to discussion on it, but really unless you let the filter get clogged up with dust I don't see a real problem.

[@verisimilitudeteller]

***** Well I use Noctua's throughout, and if you go onto the Noctua site where you get designations of what type of fan to use for which application it's not absolute. It basically rates the fans on how well they function as static pressure vs high airflow, it's a good/better/best thing, so you can use any fan in any situation, it's just a matter of how optimized for that particular situation it is, but as you said, any fans can be used. Jay said it himself, when Corsair decided to specifically label their fans for specific functions is when it all got more confusing as if to say you can't use a high airflow fan on your rad, you can, but it won't be as good as a static pressure one... etc.

[@verisimilitudeteller]

***** Big motive for using Noctua's for me though is the silence of them, I have a silence optimized case as it is, but unless I'm running Furmark and OCCT at the same time to stress the system, you simply never hear the fans. The ones I got with the case from Corsair were audible in the same circumstances.

[@verisimilitudeteller]

***** And that's fine. *grin* Just be sure to keep that positive airflow controlled as well. Intakes made faster in Speedfan than the exhaust ones, I know you knew that already, just saying for the sake of anyone else reading who didn't.

[@Nolen87]

Might be old but still wonderful, thank you very much for making this Jay!

[@adn8695]

1 simple question, i have a nzxt s340, should i get 2 sp fan on the front as intake or af fan as intake? i don't use radiator. using the cryorig r1 for the cpu cooling.

[@dogchainsaw3923]

Aiden xyz af means airflow so get that u only need static pressure unless you're using a radiator

[@adn8695]

PC MASTER RACE!!! alright mate, thanks

[@adn8695]

PC MASTER RACE!!! alright mate, thanks

[@zs2977]

I also have an s340. I just tested some airflow stuff out and found out that the filter and the front panel really restrict the airflow for the intake. I have a normal airflow fan for intake and whenever I take the front panel and filter off the airflow increases by alot. I'm probably gonna get a static pressure fan for intake since the filter and front panel block alot of air off

[@adn8695]

***** after get the sp fan let us know the result man. means lot

[@PIagueAsus]

Thanks for the clarification! I could have easily just did a little research and found my answer but you make the learning experience a hell of a lot cooler.

[@STEELERS743]

I always see people fighting over positive airflow vs negative airflow inside the case...what one do you recommend?

[@Jayztwocents]

Positive pressure when possible, it assists with dust IF you have filtered intakes.

[@STEELERS743]

Awesome!! Now you made a whole video on it....you the man Jay!

[@VincentAndre_HK]

+JayzTwoCents actually, the key for the dust would be the filtered intake rather than positive or negative pressure. no?

[@VincentAndre_HK]

Those spaces will effectively become intake. So,... The thing is with positive pressure, you normally control the intakes and that is easy to filter. In negative pressure mode, you control the exhaust and as you said, the intakes become uncontrolable and then, difficult to filter

[@VincentAndre_HK]

But the thing to filter the intakes is still valid

[@johnnymann7929]

Oh my! Jay looks so young!! 😄

[@pinchpeak5203]

He looks pretty similar. It's his voice though omg

[@BoomBaQ]

So I have an NZXT S340, i need 2 intake fans. Does the front bezel stop the airflow that much so that I need to get 2x SP Fans for intake or are 2x airflow fans good enough? I specifically want one that can blow on my GPU which gets no direct air so it gets hot.

[@isaiahrubio5548]

I have the same case and I think you are right

[@gavin6570]

Abra Cadabra I just bought two Corsair AF140s, they're pretty good for this case.

[@BoomBaQ]

Gavin Power Thanks a lot. I really wanted to put 2x 140mm fans in the front for a good intake. Now I know I can. How quiet are they at around 800-1000rpm?

[@gavin6570]

Not sure, mine are stuck at max RPM and they're kinda loud. Albeit this could be my cpu fans aswell.

[@BoomBaQ]

Gavin Power My fans are at "TURBO" in my motherboard software ( aka 1000RPM ) and I seriously can't hear them even if i try... but of course they have low CFM and they are the stock fans...If I put it into full speed you can clearly hear them, they get kinda loud.

[@cincostones]

Still helpful Jay, this helps me so much and make me return the fans i bought. Had no clue about fans at all...

[@Yosh06]

Just buy noctua they last forever

[@GGamer720]

They also look like shit forever.

[@softrockification]

I have never had a fan die on me before so.....

[@KinaestheticDmaw]

Considering that most of the Noctua brands aren't server grade (except for the stupidly expensive Industrial PPC versions), buying Noctua is utterly stupid. Most of their fans are overpriced, and don't perform as well in ALL metrics against other cheaper fans. You should aim for Scythe, Delta, etc. fans, which ARE made for constant server usage.

[@almightydeity]

KinaestheticDmaw They are mainly made to be quiet, I've had good luck with them and though the price premium is high, they are nearly inaudible. Their LNAs work well for further quieting down the system and though they don't push as much air, that's not what the NF line focuses on. Fans are fans and unless you need low power or server grade fans this is a market largely controlled by opinion as the main difference in most of these fans is 1 or 2 degrees celsius unless you want to crank them to 3000 RPM+.

[@TwenOalley]

GGamer720 They look nice imo

[@rameklee3529]

I look forward to your videos everyday Jay.I Learn everything about tech from you.

[@rameklee3529]

I prefer jay over linus

[@peoplez129]

I disagree with the suggestion. Static pressure should be the exhaust, while regular fans should be the intake. Static pressure fans are also typically high RPM fans, which means high CFM. A 3000 RPM Noctua static pressure fan can push 160 cfm. That's 2-4x the amount of a normal fan. Since the optimal setup is a negative pressure environment, you need more outtake than intake. If you do it the other way around, with a static pressure fan as an intake, the problem is you'll be pumping in more air than you can exhaust, which means air ends up lingering around components, especially in areas without direct flow. So what you want is a stream that can create negative pressure, which will keep air from lingering, and flow right on through as fast as possible. High static pressure fan as an exhaust will even help to pull in air through the intake, all the way from the back as an outtake.

[@Falcryx]

Nice point there, but what about putting it on a radiator at the front of the case? Which is better? Air flow or Static pressure..

[@peoplez129]

Falcryx In that case, a static pressure high CFM fan will still be optimal as exhaust, because it will quickly pull out all of the hot air the radiator is pumping in. You especially don't want air bouncing around the case after its been heated by the radiator, you want it to go straight out ASAP. As for an optimal radiator configuration, I would say that Static pressure at the front of the radiator (just to more easily force air through the impedance) and a regular fan at the back of the radiator would be optimal and cost effective. After all, the regular airflow fans will be receiving an airflow through the radiator from the front, so it doesn't need to suck in as much air. From there, the exhaust will do the rest. Even with radiators, I think it's still crucial to have a second unimpeded intake for fresh unheated air, or to simply use them as an outtake. My case has 2 intakes. Of course, there's a lot of different types of cases.....but if one wants optimal airflow, they should choose an optimal case to begin with. I would use a radiator on outtake just to keep it from heating up other components. Might make the radiator a little warmer, but it's sure to keep everything else cool, like VRM's, other motherboard components, etc.....those are the kinds of components that can cause a system to fail. I'd say that with liquid coolers, there's typically room to allow a few C in temperature. Most people probably have headrooms of 10-20c or more.

[@Falcryx]

C North Thanks for your effort on writing an essay xD. Yeah I agree to use radiator on the outtake, but I'll be building with an S340 which is somehow a problem for the radiator size stuff like that. I've seen that many people are using the radiator at the front tho so...

[@peoplez129]

Falcryx Well it's more so if others read it, not just for your benefit :) Most people use radiators at the intake to get fully cooled air, rather than slightly warmed air by other components, to it first. I think this approach is flawed though. While this could lower CPU temps by a few degree's, it also increases the temps of every other component. So you're essentially blowing whatever temperature the radiator exhaust is, right into the case, which is probably in the realm of 30-50c or more. I would say that outtake radiators would run cooler if the airflow is optimal, such as in my node 304 case which has a short and direct path from intake to exhaust. Since good coolers typically never get near a risky temperature, there's no harm in letting it get 2-3c hotter from running as exhaust.....but plenty of benefit for every other component.

[@D3ViiANT]

I'm really glad I stumbled across this. I was on the Corsair website and they suggested the same thing as Jay. Airflow as exhaust and Static Pressure as intake. However, your comment seems to make much more sense so I'm going to do it the other way around. Since I'm not going liquid cooled I was going to purchase a handful of fans. Two 120mm AF in the front, one 120mm SP in the rear and two 120 mm SP in the top. I think my case has an option for a single bottom mounted fan if I remove the drive cages so I'd do one 120mm AF in the bottom. That's 3 intake and 3 exhaust however all the exhaust would be SP and all the intake would be AF. 120's because I can't find 140's on Corsair's site. Corsair does have those new magnetic levitation fans that are supposed to be an AF/SP hybrid but they're LED fans and I don't want 6 fans with bright lights that I can't easily turn off in my case.

[@donfitzpatrick4647]

Jay: I've been researching cooling fans today and ran across your video. You gave great information and have helped a bunch. Let me tell you what project I am trying to finish up. I'm a slip seat driver and just put together a combination c.b. radio/am-fm radio box for the different trucks that we use at YRC. Freight trucks are bare basic trucks. Nothing inside for comfort of the drivers. I'm 60 years old and know nothing about computers. However, I am wanting to use 2 computer cooling fan in the radio box, to funnel air thru the Subarua Outback AM/FM Cassette Weather Band Radio cooling slots. And around the Corba c.b. radio. Some of the trucks are very hot inside, due to no working A/C. I wanted to keep the slip seat box contents as cool as possible. All of the remaining open spaces have been closed off with 3" foam blocks to allow the air flow only past, or thru the radios. The box itself is a military (M80./7.62mm) ammo box, which measures 17.5" x 14.0" x 7.75". I am limited to using an 80mm fan however because of the lack of space remaining after all of the kicker speakers and twitters were installed. There is nothing within 2.5" of the back of the fans locations. So, I'm thinking according to your information that I should use high cfm to push air from the lower air intakes and out the open top of the box as the air passes thru, or around the items themselves. I know this is a long comment. And one that you may not have ran across before. As, I mentioned before your information helped more than all of the other videos I've wasted time watching. Wish I would have ran across yours first. DUH!!! Thanks for the input on my question. I'll check back for your reply. Semper Fi. OUT!!!!!

2021 and the good informations never get aged

[@markcastleton9956]

Great info from a reputable source really appreciate it

[@munenemugera5548]

Good one ,I am working on bigger fan for Mechanical ventilation, but this is good demonstration

Jay for Talking about the check the check was taken

[@AbstractDucky]

Video helped me choose what fans I needed for my case! Thanks!

[@Dan-The-Orange]

I literally was going to ask you to do ta video like this soon... Thanks for being psychic!

All those fans are "free-air". The static pressure from them is honestly insignificant, but a decent comparison for per-fan purchase. The garbage about blowing sideways, vs through and gaps in blades, is also irrelevant and half BS. It is all about the blade inclination and "power", at any specific RPM. The less inclination and more power, the more static pressure and less volume. The more the blade is twisted, more inclination, the more "flow" it can produce, if there is enough power and RPMs to manage it. True fans designed for "static pressure", have little air flow. They are "blower fans", or "squirrel cage fans". You sacrafice "flow" for "pressure". It is harder to restrict an actual static pressure fan than it is to restrict a fan designed for flow. At the end of the day, given the same "power", both free-air fans, designed for static or not, will output nearly the same "flow", at the same "resistance". But the free air, low static pressure fan, will ALWAYS flow more, once unrestricted. The more blade coverage, the more potential pressure you can produce, but you can have the same blade coverage and have horrible pressure and massive flow too. Gaps are irrelevant between blades that spin so fast that the "chop gap", is literally the same. At 2000 RPM, they are "chopping" through the air with a micro-meter gap, which is almost immeasurable with any standard tool. The Vacuum created, in the chop, is what captures the drawn-in air and ultimately drives it out, as it compresses across the blades surface. That requires power. The less power you have, the less flow and pressure you will get, at any inclination. Also, that is where all the sound is generated. Also, stop calling it "water cooled", it's air-cooled with a water buffer. It takes more fans to extract that same heat OUT OF WATER, which also generates more heat, by the fans, which need more power and higher static pressure, as well as your water pump, which is also heating up the water. That's like blowing on yourself to cool yourself down. It's a redundant third-party, which contributes to the issue it is attempting to resolve. Like using an air conditioner to cool the air conditioner, so it works better. Ignoring the fact that the AC, and it's helper AC, are both creating heat in the process. Having both running inside, generating more heat than either could ever cool, at the end of the day.

Q300l case I got 4 140mm static pressure fans seems ridiculous I know but the case happens to be more metal than perforations so. 🤷🏽‍♂️ It happened to be the perfect choice after watching a listening, obstructed airflow so static pressure was the best bet and it works!

[@ravenblaylock13]

Wow I didn't even know I had them questions on fans lol. Thanks for another great vid !!

[@jonathanoxlade4252]

is it fans or fans like subscriber fans it's very hard its like we have three as free 3G three network is free lol

[@Synthematix]

Yea thats a point, why dont they make fans with changeable blades? i reckon they would be good sellers as i sometimes swap motors and blades from different brands

[@ciderandthorazine]

many thanks, Jayz - that was exactly everything i wanted to know, and nothing tangential. 'preciate it.

[@tenshi7angel]

Jayz loves water cooling, I love air cooling. Because I know that the heat has to go somewhere, and thus if your air cooling is sufficient with proper air flow, water cooling won't do much better. All a matter of buying the right fans that are designed for silent run, descent aftermarket cooler, setting up those fan profiles, so you have quiet cooling that is effective, and getting that air flow happening. Although if you want to, you can turn those fans up a bit and get some ultra cooling happening. For example, if I turn my fans up a bit, without much gain in noise, the Noctua cooler I have on my Intel i7 4790K, the cooler feels cold to touch when the CPU is idle. Obviously if you are on load, the cooler is busy moving heat, and thus it will be warmer. But the temps you will get will be impressive, because there is proper air flow along with that descent aftermarket cooler. Thing to watch out for is, any heat from the GPU. Wanna avoid sucking that kind of heat into the air cooler of the CPU. Play around with your setup so that you can avoid putting heat into the cooler from the GPU, and have fresh air coming in, and warm directed out of the case.

Thanks +jayztwocents . I wish I saw this before I bought AF fans.

[@Cessna9417l]

I've been using AF120s on my H100i with no problems, as long as the case is nice and wide open, clean and wire free, shouldn't have to be too picky about fans. Corsair 4 life

I’m a “fan” of this video. Thx for the info.

[@codybroken]

I thank you for the no-bs info
