I understand that the golden rule is:
Top and back: Exhausy
Front, bottom and side: Intake
However, my setup seems a bit odd.
So, as you can see the CPU fan is blowing downwards, towards the video card which itself has a fan blowing downwards. Both of these are blowing towards the side fan, which I have configured as intake.
I purchased that CPU cooler
because I was always seeing high temps with the standard heatsink. I'm not seeing much of a difference.
So I'm wondering if I should turn that side fan around and make it an exhaust. I know it's recommended in some situations, so I'm wondering if this is one. That's an awful lot of hot air blowing downwards, struggling to find it's way upwards - that CPU cooler is a strong fan.
