My setup:


I have the following installed:


  • ■Stock 200mm front case fan (on the lower half)
    ■Stock 140mm rear case fan
    ■Stock 120mm CPU cooler fan

My questions:

  1. ■Should I keep the 1x 200mm front fan, or replace it with 2x 140mm (or 3x 120mm)?
    ■Is the single fan on the CPU cooler enough? Is it on the correct side? Should it be sucking or blowing? (I'm not sure what it's currently doing)
    ■Should I mount a second fan on the other side of the cooler? Should this be blowing or sucking?
    ■Is having 2x 140mm (or 3x 120mm) at the front and one smaller one at the back optimal? According to the case support image below, I can fit lots more in (3 up top, 2x on the bottom)

Here is what my case supports:

Solution
Your PSU fan should be facing down if the case is vented on the bottom.

Cooler fan works better if it's on the other side pushing air through the heatsink towards the rear exhaust.

Additional fan added to the EVO doesn't improve performance.
