Case Fan Question

**BrokenApe** · 09-30-11, 12:45 AM

In my case I have a space that I can attach a 120mm to the clear side panel I actually have 2 questions... is the air supposed to be blowing out of the case (drawing heated air away from the video card/cpu the opening is over) or facing in drawing cooler air to cool said components.. also it's a fan with a 3 speed controller high-medium-low which I won't be able to monkey with on the inside of the case.. do I just leave it on High and let the smart fan controls built into the mobo deal with it?

Personally, I would make it an intake, especially if your exhaust fans are closer to the top of the case. Cool air in the bottom, hot air rises out.

It will probably work better as an intake blowing cool air onto your GPUs.

*nods* I know that can vary quite a bit depending on case and fan placement, it's an antec 1200 and most of the fans are indeed at the top of the case, intake it is then

Hi, The side panel fan/fans should be mounted as exhaust & the fan should be at full speed 100% of the time. If you look at the experienced/professional case builders,you will see the fan mounting on the side panel has no dust filter due to it being an exhaust,no filter required. Your mobo temps will rise alot if its mounted as intake.
