120 vs 140mm case fans positioning

Mr_Random_Guy · October 25, 2016

I'm getting the cooler master mastercase pro 3 soon and it has space for two 120/140mm fans in the top (exhaust) and space for two 120/140mm fans on the front (intake). I have two 120mm 1500 rpm fans I'm going to put in, and the case comes with two 140mm 1200 rpm fans. So my question is: which size fans should be intakes or exhausts?

Thanks in advance

More in than out.

I'm in the camp of more intakes than exhaust, provided of course you have dust filters for the intakes.

Agreed. I currently have 2x140mm intake and 2x120mm out fans, it's the perfect balance to limit dust accumulation while still getting good airflow to blow out hot air quickly

If you have filtered intakes use them. As long as you have a strong intake from the front of the case with multiple exhausts in the back it should be good.
