PC tower ventilation fans

I want to fit a fan to the bottom/front of an ATX tower. Does it suck or blow :-)

Blow in at the front - Out at the back!

Sorry, just read my own response - Suck in at the Front - Blow out at the Back.

Thanks Technotiger. That's IN to the case?

OK, cheers. TVM ;-)

Sorry about this: And the fan on the rear of the case - sucks OUT of the tower?

sucks OUT of the tower?

The idea is to draw cold air in from the front and blow hot air out from the back....

OK thanks. The huge fan on the PX unit (facing down to the bottom of the tower), presumablly that takes cold from outside - through the unit and in to the tower where it's sucked out by the front/rear case fans?

Sorry - sucked out by the rear fan....duhhh.

The fan on the PSU (if that's what you meant) sucks air from inside the tower and blows it out through the PSU.

If you fit a fan to the bottom of an ATX case it should suck from the outside (ie blow into the case).

Intels suggested design for ATX case shows such fans - the idea is to blow the hot air away from pooling under the graphics card.

PX unit = PSU ????

At the bottom of the case?? - that's unusual.
