Accordingly, I devised a simple test where the only changing variable was the number of fans used, or how they were mounted. However, if you go for an AIO, you can certainly get away with 2 intake fans. Step 5: Push / Pull is about how you position fans to move air through a heat sink or radiator. Just food for thought. On a rad you can get most by blowing air through it while fans like to cake on the blades and it can be hard to get in each nook lol. Overclocking Why do my GPU fans need a push start? Lets make it more specific, instead of thinking of the effect of other fans on the system, lets consider a radiator outside of the case with 2 fans pushing air through the fins or 4 fans in push pull configuration. What do I need to know? As a direct comparison, if you were to add a (matching) fan to a given AIO, they could develop greater static pressure working together. To get accurate data from comparing various fan configurations, it was very important I devised a scientific and easily repeatable test. CPU fan pushing air … I bought more Corsair "quiet" PWM fans when I saw the 2-pack at Fry's. Push-pull fan configuration will allow you to get even better thermals and make sure you squeeze some more MHz out of your hardware.

I tryed what he did and it seems to work on my G75 VW as well. Generally the push fans are high static pressure (usually 3-pin DC). In Eurpose, metric fans are rated in m3/hr - cubic metres per hour (m3/hr). For a GPU, the difference comes in how those fans on your graphics card get rid of that excess heat. To get a temperature reading, I ran Prime 95’s (version 26.6) Small FFTs test for 10 minutes before noting down the maximum CPU temperature. The cable coming from the fan header has two in-line 4-pin connectors. But as said it depends on the fans and the radiators. I was wondering which way would be better for the fans since the whole enclosure is external. pull would be easier to clean but I feel push would be more efficient.

Depending on the graphics card length, you can also run a push-pull setup like I do for my personal system at home. Do you guys use any special kind of fans for that, does it need to be at a certain speed to be able to pull through the filter? So you can run the fans slower for the same cooling. However, I remember feeling very confused about how I should mount the fan to the heatsink – some people said ‘just stick it on any way’, while some online pundits were certain that I HAD to use two fans in a push/pull configuration or else my PC would burst into flames at any moment. *laughs* I mean, yeah, you’ll have better cooling with push-pull than with just push or pull. To properly air cool your computer, you need have enough case fans to push or pull air into and out of the case. That means a 70CFM fan will move 70 cubic feet of air in one minute.

Lots of people like push but as much hate as Ill get pull has its advantages. First of all they have long warranties, typically 8 years, and you don’t want to upgrade to a more powerful CPU or GPU … Most GPU coolers blow air to the GPU, but there are some reference coolers that push air out the case. It's just that one is pushing air into the heatsink, and the other is pulling air out of the heatsink. Push or pull makes no difference for the radiator. Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. These fans take in the hot air from the inside of your PC case. Another thing we’d like to note, not related to the push-pull configurations is that Vardar fans do slightly better in pull configurations. With this we conclude the push-pull testing, and we hope that we’ve helped you choose what kind of fan configuration is right for … Step 4: Simply, pull out the GPU by following Step 2 of “cleaning the fan”, that is mentioned above.
