Power Supply Up Or Down?

Ben3991 · 8 Oct 2011 at 19:58

Hi,

A silly question i'm sure, but is it best to have the power supply fan facing up into the case or down onto the floor?

My power supply is an xfx 650w

Thanks

Doesn't matter really, my case has vents at the bottom so I have it facing down.

Mine has vents at the bottom to. I just think face down it has minimal air flow to it. But im not sure if its an exhaust fan or intsake fan

It's intake, PSU's blow the hot air out the back. Mine never gets very warm at all.

Ok thanks, yer so I guess fan down, and an external fan to help air flow under case would be best then

Thanks again

I wouldn't worry about an external fan, unless your case sits right on top of carpet or something.

is your PSU mounted on the top or bottom of the case

and

does your case have vents at the bottom?

My fan is up.

Reason is even though I have vents in the bottom my tower sits on the floor and would suck up loads of dust

That would be facing down unless you have the case on deep pile carpet which will block the vents.
