I am assuming the CFM and pressure increases, but is it additive, multiplicative, is there a point of diminishing returns?

Hi, any suggestion for best fans for radiators? I have 1 360mm 27mm thickness and 1 140mm 29mm thickness, the EKWB fans that came with the kit are so noisy even at low speeds (1200rpm) and I dont seem them push air that much. your advise is needed for for best static pressure fans, and best value fans as well. thanks.

Hi There, I'm looking for some advice on some static pressure fans to replace the stock ones for my Kraken X62! The stock ones were crap and the frame snapped on both while mounting them before they were even tight. I don't want to go through the hassle of an RMA just for the stock fans. I'd prefer black, but it's not a big deal since they are mostly hidden by the radiator in the front of the case. I have the X62 mounted in the front of my case because the tubes are way too freaking long to top mount. I have the stock fans still in right now but I'd like to replace them since the frames are broken on both. Currently, the cooler is mounted in the front of the case with the fans mounted in front of the radiator (towards the outside of the case) pulling in air from outside and pushing it into the radiator. I also have 3 x Corsair ML120mm White LED fans in the top of the case exhausting air out as well as 1 x Corsair 140mm White LED in the rear exhausting. If you think this set-up is incorrect and needs revising let me know. My computer specs are listed in my signature but I'm using a Phanteks Enthoo Evolv TG case. I'm hopefully looking for a mixture of performance and quietness but performance is valued higher. The case isn't very quiet as is because of the tempered glass side panels and open design so there's no sound dampening foam so complete silence isn't achievable as is. I have included a picture of my PC as it is now. I'm currently thinking of Noctua NF-A14 iPPC-3000 PWM ?

Hi everyone, I am trying to upgrade my fans in my pc at the moment as the fans that I have are quite loud and I cannot ammend the speed without doing power changes. Could you please reccomend some fans to me run with. My case is the 540 air by corsair, I have a h100i v2 in there and was thinking of getting 120mm noctua industrial 3000 rpm pwm fans for the h100i and replace my corasir af 120 LED's with industrial 140mm 2000rpm pwm for all my case fans for airflow. I am looking for high performance if needed while being as quite as possible most of the time until I need the cooling to be better when running benchmarks and overclocking harder than normal. any advise would be amazing.

I am in the process of planning a build and have fell deep into the rabbit hole on the cooling aspect. Hence the probably way too in-detail post. I apologize if I scare you off with this wall of text and deeply appreciate anyone who replies with advice. As this question applies to both water cooling (CPU & GPU) AIOs and case fans I have submitted this query to both Air & Liquids forum boards in hope of reaching a wider audience as I have seen posts on AIOs in both. Question: I am looking at replacing the stock fans on both the case and AIOs with something quieter/better performing. At the end of my post are the specs for all fans (stock & considered). First question being, what option below will provide best cooling performance for the CPU while maintaining a low db level? Options: [1] Kraken X52 (240mm) - 2 fans in Pull, Exhausting Top - 146CFM/5.86mm-H20 (with stock fans) [2] Kraken X52 (240mm) - 4 fans in Push/Pull, Exhausting Top - 293CFM/11.72mm-H20 (with stock fans) [3] Kraken X62 (280mm) - 2 fans in Pull, Exhausting Top - 196CFM/5.42mm-H20 (with stock fans) My case has a removable Radiator Bracket on top (hence why I plan to place the radiator on top in exhaust) and I plan to mod the top bracket to allow for option 2 if needed. I have done enough research to know that option 3 is better than option 1 as there is more surface area for cooling. I also know that option 2 is better than option 1 due to increased static pressure and flow due to more fans. I also know that 120mm fans are better at static pressure when trying to achieve low db levels and I want to stay low as possible (20db-30db) Second question is how much would I improve or hurt performance if I changed the fans? I am looking at replacing the stock NZXT AER P 120mm on the Kraken X52 with the be quiet! BL070. That would gain me 200 higher max RPM / equal CFM / 0.44 higher mm-H2O / 7.4 lower db. This seems like a no brainer. However the Kraken X62 is another story. After looking at be quiet!, Corsair, EKWB, Fractal Venturi, NZXT, & Phanteks I can't seem to find a fan with good static pressure and low db. (I know you can't have your cake and eat it too but I am going to try my best) Only one fan I found beat the static pressure of the stock Aer P 140mm and that was the Corsair ML140 which had 0.3 more mm-H20 but equal CFM and db levels. The closest quiet fan is the be quiet! BL071 which would lose me 200 max RPM / 20 less CFM / 0.55 less mm-H2O but gain me 9.9 lower db. Would it be worth the performance hit to drop nearly 10db? Again, the fan spec chart is below for comparison. If anyone can provide a make and model of a fan that can get me something better please do so. My third question would be on positive versus negative air pressure in the case. I know that positive is best to help prevent dust from seeping in the cracks, but also to balance it so there is a good amount of airflow. With this in mind, is Flow (CFM) the only value to look at (other than db) or should I still consider the Static Pressure (mm-H2O) since I will be pulling air in from a meshed intake? If I swapped out the 3 stock Phanteks PH-140SP with their 82.1CFM/1.33mm-H2O used for intake (1 Fan-Back & 2 Fans-Front)(246CFM/4mm-H20 combined) and use both the be quiet! BL071 with 77.57CFM/2.16mm-H20 (1 Fan-Back) & the BL070 with 73.3CFM/3.4mm-H20 (3 Fan-Front)(298CFM/12.3mm-H20 combined) for intake, it would be a 52CFM/8.3mm-H20 increase to change from stock Phanteks to be quiet! with a 9.1 db decrease as well. That’s great, but is still only 5 SCFM more than the option 2 exhaust. Would that be enough difference if option two provided to be the best solution? Fourth question is about the GPU radiator. Should I put my 120 radiator for the GPU on front infeed(Pull) or back exhaust(Pull)? If I put it in the back I'll lose the 140mm BL071 fan to a 120mm BL070 fan and lose 4.27CFM leaving with me with almost no case pressure. Also, if I do front I would have room to do Push/Pull as well. Is it worth the extra heat dissipation to have a 3 stack (fan|rad|fan) in the front of my case and have a harder time cleaning the radiator? Last question; am I overthinking any or all of this, & why? Background: I will be building in a ENTHOO EVOLV ATX TG Case. I plan to use either the NZXT Kraken X52 or 62 to cool my CPU. I will be using either a 1080 or 1080Ti. For a 1080 I would go with the EVGA GeForce GTX 1080 8GB Hybrid. I am hoping for a water cooled 1080Ti, but such a thing has not been revealed yet. The mobo is a ROG CROSSHAIR VI HERO with support for 5 PWM connections and the case comes with a PWM HUB that control up to 6 fans (reading only the RPM of FAN1). The Kraken supports 4 PWM fan connections. I would prefer all PULL configurations with fans and radiators as I have researched that this allows for easier cleaning with what dust does infiltrate the case. Please keep in mind when replying that this is my first large ($$$) build and I do not feel comfortable attempting a custom loop (as sexy as they can look). I also am not looking to go the EKWB predator route or anything similar. Thanks again for any advice or support you can give.

Hey everyone, I need new case fans for my Rosewill Thor V2 as the bearings are going bad. I was looking at corsairs af140mm but I'm only finding static pressure and I wanted to hook them up to the built in fan speed controller. Would I still be able to change the speed with them connected even though they're static pressure or would I need pwm fans?

Hi, guys.... So this is going to be a dumb post but bear with me. I'm getting a Phanteks Enthoo Evolv ATX TG edition case and i wanna know what the best fan config is for it. This is what i was thinking. An AIO cooler for the CPU at the top, which is 2 * 140mm fans . (dual Corsair SP140 exhaust) -yeah i think i prefer the radiator at the top not the front. One fan at the back (Corsair AF140 exhaust) at the front, you have room for dual 140 (which can be put on the top 2 slots or the bottom 2 slots but you can't have 3 140mm fans) or triple 120. Now for the front is where my problem comes in. as you might know in this case the hard drive cage is at the bottom of the case so half your bottom fan is going to blow down there. My question is, should i put 3 120mm fans or two 140mm fans in the bottom two slots? (All Corsair AF and all intake) Also in Linus's video The Most Popular PC - Viewer's Choice Nov 2016 (check it out if you haven't) he mentions that we should be buying Corsair's SP fans because they are better all round. what does this mean? are SP's better for air flow than AFs? i'm confused. Should i just buy all these fans as SPs? coz the only SPs i was gonna buy are for the AIO cooler (which by the way I've decided to go with the NZXT Kraken X62) also please note that my graphics card is either gonna be a Gigabyte G1 Gaming 1080 or an ASUS GTX 1080 Strix or an EVGA GTX 1080 FTW Gaming (side note--- which of the three should i get? lol) all airflow intensive cards. help?

I am hoping to get some feedback on what I am thinking in terms of my cooling strategy for a new build. I am also trying to double check if I will need any additional power adapters or extensions, so I can make sure to order all the parts that I will need. It would be very valuable to me if anyone wants to walk me through specifically how you would expect to power the fans, either through the motherboard or directly off the power supply. I am interested in what connections, extensions, or adapters you would need to do that which I will need to order. I am new to building PCs so this is as much about learning how to do it as it is about getting better performance. I understand that some of what I am doing may be over-thinking a fairly basic build but I want to learn what I can at the same time as I try to make things a little bit better. I value silence highly, though I understand that I will need to put up with more noise than I would wish. I also value performance. I do plan to learn to overclock with this machine so that may factor in as well. I do not care at all about RGB lighting and would prefer not to deal with it. A matching color scheme to the components is also irrelevant to me. The new build I am working on is here: https://pcpartpicker.com/list/qRHgVY I already have the Case, Power Supply, Optical Drive, and Keyboard. I have already placed an order for the GPU, RAM, and Motherboard. I am in the process of building my final orders with retailers trying to make sure I get the number of fans and any additional wires I need correct to save on headaches and shipping. I am new to shopping for parts, so am not very familiar with brands or the level of quality they represent. A lot of the reviewers I have been watching seem to favor Noctua for performance, but I am open to other brands as well. I have been watching some videos to become familiar with concepts like positive pressure, and static pressure vs airflow. I am going to shoot for positive pressure in my system. The case I picked out has 2x 120mm fans that came with it; one is on the front as an intake, the other at the rear as exhaust. I was planning to leave them in place. The front panel has filtering on it, so I was going to add another 120mm fan with good static pressure on the front even though it will be somewhat obstructed by the drive shelves behind it. So that would be 2x 120mm fans on the front for intake. Then the open side panel has ventilation and places to install fans so I was going to install 2 more fans (140mm) there as intake with a filter in front of them. I was thinking going for static pressure fans for those as well. Then the top of the case has a lot of ventilation cut into it with room for more fans. I was thinking of just using one 140mm high-airflow fan on top at the rear without a filter for exhaust. So I would end up getting 3x 140mm and 1x 120mm fans, plus the 2x 120mm fans the case came with. I would be pulling air in from the side and from the front, and pushing out the back and top. There is more ventilation on the top, back, and bottom where I hope the positive pressure will be pushing air out. The fans from the GPU seem a little odd to work around without creating a bunch of turbulence but it seems to me like the GPU fans won't conflict with the setup and will help push some air out the bottom of the case. The PSU is on the bottom but seems isolated by the walls of the PSU, except for what may come back in through the bottom of the case; but I think the positive pressure with some help from the GPU fans should take care of that. The ventilation in the side panel starts near the top. It looks like it would set the intake fans next to the CPU cooler. I am not 100% sure the top one would fit with the CPU cooler installed. Another thing I may consider is trying to rotate the CPU cooler to push air up instead of towards the back of the case, if the mounting system will allow for that. With all of these fans (I realize it may be a bit overkill) I will expect to have the 2x 3pin connectors from the fans that came with the case, plus another 4x 4pin connectors from the additional fans to plug in. I am having trouble telling exactly how many fan connectors there are on the Asus motherboard. I also don't know if I will need anything extra to plug some of the fans into the PSU. There is a "Peripheral" cable that came with the PSU which has 4pin connections that seems promising, but that seems like it would be female to female connections, unless the needed parts are included with the fans. Obviously I don't know what that cable is really supposed to be used with. Any help or insight is appreciated. I will continue doing research into the fans and trying to figure out the pins, cables, and connections. -JD

Hey fellas, I live in Chennai, India. Ambient temps will be around 30c-35c during non summer time, and easily 35c+ during summer easily, wanna keep my components cool as much as possible. lemme know which of the fan setup is better for the time being, looking to replace fans. In my opinion my current setup doesn't exhaust well good at top coz of low air flow pressure of Phanteks stock 120mm fan and the case's top dust filter and honey comb (mesh) structure which is at top, after few hours of gaming the dust filter gets warm, the dust filter doesn't get this much warm when i had 2*120 mm Cooler Master SickleFlow X as top exhaust. And I bought 120 mm Cooler Master SickleFlow X's without thinking abt cfm of these and static pressure, coz of intake restriction p400 got, only small slits to intake at front of the case. Current fan setup: 3*120 mm Cooler Master SickleFlow X as intake and 1*120 mm Cooler Master SickleFlow X as rear exhaust, and 2* Phanteks stock 120mm fans as top exhaust. Previous fan setup: 2*120 mm Cooler Master SickleFlow X as intake and 1* Phanteks stock 120mm fan as front intake. 2*120 mm Cooler Master SickleFlow X as top exhaust. 1* Phanteks stock 120mm fan as rear exhaust. Need fan suggestions which is perfect for my P400 build CPU Intel i7 6700k Motherboard Asus Z170 Pro Gaming RAM 1*16 GB DDR4 2400 MHZ GPU nVidia EVGA GeFore GTX 770 SC (soon to be upgraded) Case Phanteks P400 Storage 1*7500 RPM 2TB HDD WD Black PSU Seasonic M12II-850 Fan suggestions: Best 120mm which I can mount on my front to draw as much air as it can from the slits. Best 120mm/140mm fan at rear exhaust to push as much air out of my case. Best 120mm/140mm fan at top exhaust to push as much air out of my case and air filters. One more doubt all say CM's JetFlo 120mm which has around 95 cfm is inferior to Noctua's 120mm whose cfm is 55-65. higher the cfm means it can allow more air flow right? Enlighten me, Ty in advanced.

Hey there Digitec currently has a sale on Fans (Digitec is like amazon in switzerland). So i would like to replace the Fans of my corsair h100i v2 with some that sound less like a jet starting right next to your ears when under load. I would run them in pull (not push/pull since that wont solve the noise problem and my wallet would not be happy neither). But for pull should i use fans that have a high static pressure or that are more Airflow optimized? I want to run them in pull so that maybe my GPUs that are in SLI can breathe a little bit more. The two candidates would be: https://www.digitec.ch/de/s1/product/cooler-master-masterfan-pro-120-air-pressure-rgb-120mm-1x-pc-luefter-6474462?tagIds=76-526 https://www.digitec.ch/de/s1/product/noctua-nf-f12-pwm-120mm-1x-pc-luefter-288033?tagIds=76-526 Also as i said they should be more silent in the higher RPMs, since they dont run if the CPU isnt doing anything. Thank you for your answers.

I'm going to buy NZXT H440 (New Edition Silent Ultra) white case and it comes with 3x 120mm fans in front and 1x 140mm on the rear. The case is lovely but has somewhat restricted airflow in the front and on the top. I'm going to use Kraken X62 AIO cooler on top. Would replacing the front 120mm stock fans with NZXT's new Aer-P static fans do any notable difference? Case: here Aer P fans: here Thank you in advance!

I recently bought a coolermaster k380 case and since it isn´t a very common case I wanted to gather some thoughts about which type of fan I should use for every spot possible. I attached a picture of the case FYI.

Hi guys, So I saw a listing of the Scythe Gentle Typhoon 5,400 RPM 120mm fan. There seems to be other versions of this but with lower RPM, I found it interesting because I've never heard of a 5,400 RPM 120mm fan so I thought of checking it out and some videos of it was really loud. I was just wondering if this fan would be nice for my Cooler Master Hyper 212X. Is it good enough? I wouldn't want it to run the full 5,400 RPM, but I think it has a molex fan header instead of the 3 or 4-pin fan header. The only downside I see is it doesn't have the bling I want, like LEDs and stuff. Just a thought though. Any insights? And out of topic - just want to share this cool insane video I just saw It's sooo crazy.

I would like to replace the stock fans in my PC case, the Cooler Master MB500. I am putting a 360mm radiator in the front, and I want to put ARGB static pressure fans on that radiator. The fans I'm thinking of using in the rest of the case are Deepcool CF120 fans. They seem really good for airflow (exhaust in the top and rear of the case). If anyone can tell me about some good fans to choose from, I'd really appreciate it.

So I was looking this this NF-B9 redux-1600 PWM compared to this NF-A9 PWM. The Redux will better match my build but the static pressure of the redux is 1.61mm compared to the NF-A which is 2.28mm. This seems like a large difference and the fan will be pulling through a CPU cooler and a side panel the CPU cooler is pushed mm away from. Is the static pressure going to make a difference? Couple degrees? Thanks!!!

Hey everybody, I'm looking to add some new fans in my case, because I currently have only one stock intake fan that came with my Phanteks p350x. Currently, I am deciding between the Be Quiet! silent wings 3, and the Corsair Ml140's. I am wondering what the better of the two is for intake cooling options. I keep finding conflicting opinions about these fans. I know there are many other good intake fans, and if there are any that you feel passionate about, go ahead and tell me about them, I am open to any opinions about your favorite fans. I am mostly looking for a fan that isn't noisy, has pretty good static pressure for intake airflow, and looks decent (not Noctua brown, just like a solid black or something). Hopefully, yall can help me figure this one out. Thanks, -Earn

I recently learned about the differences between static pressure fans and air flows fans, and after naively thinking that CFM was all that mattered, have decided to reevaluate the intake fans I've chosen for an upcoming build in order to make sure that I am maximizing efficiency. The case I'm going to be using for the build is the Cooler Master MasterCase H500, which allows the owner to choose between a mesh or acrylic front panel. I'll be going with the mesh panel to restrict airflow as little as possible. Additionally, the case supports 3x 120mm fans, 2x 140mm fans, or 2x 200mm fans as intake fans. Now, with that being said, I'll list what I've chosen and my reasoning for it below: I chose: 2x Cooler Master MegaFlow 200mm fans Reason: Back when I thought CFM was the only thing that mattered, I came to the conclusion that out of all possible combinations of fans that operated under 25dBA (that I knew of), these two fans achieved a higher total CFM than others while being less costly to acquire. However, after learning about static pressure, I realized that the static pressure of this fan is rated at a low 0.595 mmH2O. If a higher static pressure rating helps fans push and pull air through small spaces such as heatsink grills and the small holes in a mesh filter, then wouldn't the MegaFlow have trouble pulling air inside of the case even with the acrylic front panel replaced by the mesh panel? Should I seek out fans with higher static pressure to use as intakes instead?

Looking for high CFM, good RPM and excellent static pressure high-end 4 pin PWM controlled fans (not concerned with sound levels) for the somewhat "airflow deprived" Phantek Evolv X chassis. All help is appreciated

I'm buying cooling fans for my Fractal Design Node 804 today. I've decided on the BioniX line from Arctic. I cannot decide if the static pressure optimized version (P) is better suited for my Node 804 or their case fan variant (F)? Both offer similar CFM (high 60's) The pressure optimized has a 2.62 rating and the case fan variant doesn't publish static pressure measurements. For those who are familiar with the Fractal Node 804, it does have a (very) restrictive front panel and grille slits cut in the top fan positions as well (and 3 filters total). I'm buying 8 fans so I want to be certain. 4 front intake 1 top intake and 1 top exhaust and two rear exhausts. Should they all be pressure optimized versions or mix of the two versions? I am trying to keep the fans all the same for PWM and temperature tuning reasons. This is a split chamber design computer case. Pic one is the pressure optimized BioniX. (With less blades) At bottom is their non-pressure optimized version. (More blades, thinner blades)

I was wonderring what type of fans are better for exhaust. Air Flow fans or Static Pressure fans. Without radiator ofcourse

I built a gaming/editing PC recently, specs are as follows: CPU: AMD Ryzen 5 2600X RAM: Corsair Vengeance RGB Pro 16gb 3200mhz Motherboard: MSI B450 Gaming Pro Carbon AC GPU: XFX RX 580 8GB Black Edition PSU: Bitfenix Formula Gold 650 Watt Case: Cooler Master Masterbox MB500 I'd like to replace the stock fans with new ones, and I'm even planning on putting a 360mm radiator in the front. I'm thinking of using Corsair HD120 RGB fans in the entire thing, but I've read that they are mostly good for static pressure situations, and not so much for airflow... is that true? Should I switch to the LL fans? Or would I put HD fans on my radiator and LL fans on the top/back for the exhaust?

Using really long screws could you mount a 140mm fan onto a 140mm radiator with this adapter and funnel the 140mm fans static pressure through a 120mm opening to have superior airflow? __ ___ ~~ X \ | | ~~ X \ | | ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X | | ~~ ~~ X / | | ~~ X__ / | __ | __ ~ X _/ | | ~ Air Fan Funnel Radiator Air NOTICE: Air is 14 units wide before at 140mm fan and after 120mm Adapter is only 12 units wide.

Alright, so I'm building my first ever PC very soon. The case I chose was the Phanteks P400s TGE. However, I chose it for its sleekness and tempered glass not for it's functionality. I know it doesn't have the best air flow so that's why I'm here. I need to find some good 140mm static pressure fans, preferably between $10-$20.

Hi I’m going to build a pc and I’m wondering roughly how much radiators restrict airflow in CFM. I will be using static pressure fans on a 30 mm thick radiator with 3 exhast fans. Thanks.
