Air in or Out??

[racerboy45]

What's the norm out there when installing a PSU?, or is there one? Do you have the PSU sucking air from outside the case and then have it sent out the back of the case or do you suck air out of the case and send it out the back??

Thanks..

PSU's always exhaust warm air from the case. Unless you open the case (thereby voiding the warranty) and reorient the fan backwards, it will exhaust the air from the case.

Tracking on the PSU exhausting the air out the back, maybe my question wasn't stated in the best manner. My case causes me to mount the PSU on the bottom, so depending on how I mount it there I can either have the intake fan bring in cool air from outside the case thru the bottom and get exhausted out the back or I can have the intake fan facing up and inhaling the air from inside the case and then exhaust it out the back. I was just wondering if there are any advantages or disadvantages of doing it either way.

@OP
Does your case have any other exhaust fans? If the answer is no, then set the PSU upright so that it takes in air from inside the case and exhausts it out.
On the other hand if your case already has one or two exhaust fans already you could try placing the PSU upside-down and get better cooling for the PSU. [Assuming there is sufficient space between the bottom of the case and the floor].

Come to think of it, if the Case is standing on the floor, you're going to clog the PSU fans easily with dust and that can damage it too.

In conclusion, I'd say upright would be better

Thanks, I think I will go with it pulling air from inside the case, I have 2 140s on the top of case sucking air out, H50 push/pull from the back and a 120 from the front and 1 from the side pulling air in.
