post #1 of 15
Thread Starter 
For PSU's with one 120mm fan (facing down when mounted at the top), which way does the air flow?

doitallman is right, it would blow out the back. Your case may get warm after awhile if a PSU would blow into the case I guess it would depend on your case setup to see where you wanted the fan. My Thermaltake 430W's airflow goes from front to back, but my Corsair 520HX sucks from the bottom. I would think that sucking from the bottom would be better, since it would get rid of some of the CPU HSF's heat.

Blowing out into your case. It is taking the heat inside your PSU and releasing it.

I thought doitallman was saying that the 120mm fan is blowing out, as in away from the unit, which would be a downward airflow if mounted at the top. But then that air would be sucked out by the rear exhaust.

That poses another question: With case fan in the rear, are they all taking air out of the case, or bringing air in? Or is this up to the user?

See, now that's exactly what I thought, but I didn't want to assume anything.

my psu (see sig) pulls air from inside the case and blows it out the back. i also have a 120mm rad fan that is also pulling air out the back. additional case fans are up to as to which way they go. every psu that ive ever seen takes air from inside and blows it out.
