Intake or Exhaust side fan? - Page 3

post #21 of 34
If you have a front-bottom intake fan, it would be better because those cards also need fresh air. Fresh air usually lowers temps upto 5-7c. My intake for my single card is on the side, but in your case, since your cards exhaust towards the side fan, you need to set it as exhaust, remove filter but keep the mesh. A front-bottom(or a bit above) might help cooling cards better.

Yes thats usually the way but just with these particular ASUS gpu fans which would be blowing hot air exactly against the cold air from the side fan, not sure how much it would help.
Will try exhaust first, monitor the temps and then try intake too, see which is better.

Haven't got a chance to test intake yet, been busy but the only other bad thing might be is that since I had to mount the fan on the outside, there is a small gap (~0.5cm) between the fan and the plastic window on the side panel, since the fan is attached to the metal grill.
That might not be good for exhaust since its not a vacuum at the mount point.

Nothing to attach the fan onto then. Since the side window only lets you put it inside but no room due to CPU heatsink so needs to go outside

Ok intake seems to be the same, maybe 1C less but hard to tell.
Probably need a fast/loud fan to see bigger difference, this fan is ~1300 rpms at full speed.
