Fan Setup Help

[hamo158]

Hey guys,

Just wondering what the best fan setup for my system would be.

At the moment I have:
two 140mm fans as intake at the front
one 120mm fan as exhaust at the back
and two 120mm fans also as exhaust going through the top mounted radiator.
Everywhere I look they say positive air pressure is better, but if I had the two top fans as intake that would only leave one 120mm fan as exhaust..

Thanks, Hamish

As far as airflow goes, its better to have more positive air pressure to keep the dust out vs having negative airpressure. I dont think they explained that, even though if more air goes out your case, the heat/temperature aspect will remain the same due to the dust that remains present. My recommended setup would be what you have right now. What case are you using?

I'm using the BeQuiet Silent Base 800, so there is space for two more fans on the side panels.

Great, so if you can, add one more fan on the side (preferably a 140mm for better noise), and then you should be fine. I'd recommend one of Be Quiet's Silent Wings series.

Thanks heaps!
Also, the stock fans that came with the H100i GTX are quite loud, do the fans that cool the cpu have to be of high rpm or does it not matter so much?

It matters more about the radiator size than fan speeds. The heat will dissipate from the radiator faster if the fans are faster, but if you have the money you may want to replace the fans on that unit.

Sweet, thanks for your help!
