Intake or Exhaust side fan? - Page 2

post #11 of 34
It's a clip fitting, so try it both ways biggrin.gif
And if you do run it as exhaust, remove the filter smile.gif

On my 900/2 I had that fan as intake! Mainly because that fan spot has a filter. So I figured it was intake headscratch.gif
But my DF-85 has no filter! So I tried as exhaust, and yeah I'm happy with it that way too smile.gif

Have you tried having a fan in that side spot??
Because, I had to mod a fan so it cleared my CPU cooler thinking.gif

if its on the side facing the GPUs then do intake, always do intake for more cool air to them

Yes will have to mount it outside since the cpu heatsink takes up one of the corners so it won't fit inside.
But might give your "cutting corners" idea a shot wink.gif

Not sure if that will help much since I will be blowing cold air onto the gpus but the gpus will push hot air onto the fan in the same spot.

Wow there are so many threads about this and basically it goes 50/50 intake/exhaust.
If you go at it mathematically I have 2x 120mm = 240mm intake and 1 x 120mm + 1 x 200mm = 360mm exhaust therefore if its intake it will even out 360/360.
Then again I have my gpus in slots 1 and 3 since they were getting hotter in 1 and 2, the lower gpus is 15C cooler than the top one even at idle and the side fan will probably not blow anything on it being lower, and the one in slot 1 will blow hot air over the fan.
Hmmm

The only way to know is do both and monitor!

I would normally think you want cold air blowing onto the gpus so they can suck it up?

You can try exhaust, be aware this will most likely result negative pressure (dust buildup). Whatever you do, set it to low speed so that GPU can still sucks air in.

I would say, since it only takes a few seconds to switch it from exhaust to intake, try out both and compare your temps... Heck of a lot faster than waiting for someone to tell you what will definitively work best for you. thumb.gif

I agree to this. Try both and see which one works better for you. It is a very quick fix to flip the fan around.
