case fan

lucius octavion · August 6th, 2006, 02:05 PM

Hmm, a question. Should a case fan in the back of a pc blow air into or suck air out of the case?

The thing is... I really don't know which way the fan is supposed to face into the case...

It has kind of a grille on one side.... And the screw holes aren't really threaded

A case fan should do the opposite of power supply fan.

What does the power supply fan do? Or does that depend as well?

Any fan towards the top of a case should blow out... fans at the bottom should blow into the case. Heat rises so out would be exhaust. Most fans (On the edge near the power cord) have arrows that show the direction of the fan. Most fan screws are self tapping so threads are not needed.

PS fans in the rear of the unit blow out, secondary fans on PSUs in most cases blow into the PSU.

What do you mean by self tapping?

Self tapping screws cut (create) the threads as you turn the screw into the hole.

Yeah, I'm just worried about stripping the screws
