If I have a case with power supply on the bottom and a vent on the bottom of the case as well, does it matter which way the fan is facing? I've done it facing down always and never had a problem. However my manager says it should be facing up

Your manager doesn't know what he or she is talking about. redface.gif

It should be facing down because the fan is an intake fan and therefore it pulls in the cool air from underneath the case through that vent, and it pushes it out the back.

it doesn't really matter, but facing down just makes it pull it cool air from outside the case.
I have mine facing down only because that puts my cables all coming out right next to the cable management hole. It also makes the sticker on the back of the supply face the right direction.

Thank you. I had him and an employee get on me for installing it facing down for a customer.

If your case is sitting on carpet then it should face up because carpet will block most of the air. Otherwise face it down.

lol! I'm not surprised. It seems like every single time I hear about something someone said who is not an OCN member but just some person out in the world somewhere, they always turn out to be wrong.

If they insist that we are wrong, then ask them to tell you which side of a fan is intake: the open side, or the side that has those 4 'bars'. If they don't know, then you can point out to them that the intake side of a fan is always the open side (the side where there's nothing between you and the fan blades).

After that, have them study the fan inside the PSU and ask them to tell you which side is facing up: the open side, or that side with the 4 'bars' (there should be a normal fan in there).

If they still don't believe you, then tell them to just get out of your way and let you do your job.

Since you said it has a vent on the bottom and it's mounted at the bottom, definitely have it as an intake. Just be sure that there's some sort of dust filter covering the PSU, I lost my last PSU thanks to dust build-up.

that is always 100% true. I have a fan down stairs that intakes from the closed side, and exhausts from the open side, I was like confused.gif when I first turned it on. I would also like to say that the fan is a 120v fan, not a normal computer 12v fan.

Then they should do what I did, here's one of my computers:

picture.php?albumid=3818&pictureid=21854

now they can face the PSU fan down with no worries.smile.gif
