Hello

I recently purchased a fire breathing 7990 and need to make sure my case cooling is optimal before I integrate it into my system.

Notes
  • The large black block is the cpu radiator.
  • 9 fans in total
  • Corsair C70 case
  • The gpu has 3 fans exhausting air DOWNWARDS along the length of it
Any advice is appreciated, thanks!
 
Personally, I would have the top and rear exhausting and use high static pressure fans on the intake as they will help cool the GPU more.

What temps are you getting?
 
Does the GPU really blow that way?

Normally they blow towards the bottom or out the back.

If its one that blows out the back of the card (and the card exhaust is near the front) it may be worth reversing your airflow. [top and rear IN, Front OUT].
 
I'd go with:

Intake:

Front (4) and Top (2)

Exhaust:

Rear (1) and Side (1 - only on the lower 120mm vents).


That creates two independent airflows - one for the upper half (memory/CPU/northbridge), and another for the lower half (GPU/southbridge). You'd have 1 x 120mm fan left over, could keep as spare if there's no room on the floor of case.

Reason I wouldn't use the upper 120mm vents on the side panel is because then there'd be "fighting" between the rear exhaust fan and that one, and the air intaked from the top won't be drawn across the motherboard and out the rear (as much).

I would definitely not have one top fan as exhaust and another top fan as intake, as pictured in the diagram, for the same reason.
 
I think the front panel works fine, i've always been unsure of the cpu cooler being at the top. Does this case have enough exhausts?

Thanks for comments...
