daft question but....

back

does air get sucked in at the back and blown out the side? I've got a vent from the CPU stock cooler out the side of the case, I'm sure it's a vent so am I right in thinking that air is sucked in from teh back?
 
the fan is on but hard to tell, I think the back fan is the vent and the intake is the side...ah well, just a general query ;)

cheers
 
If it's an exhaust fan you'll definitely be able to tell if the air is coming out. The intake is more likely to be at the front/side.
 
Just like Microwave said, most cases tend to have the intake at the front (possibly a side vent too). In almost all cases the exhaust comes out at the back.

If there's only one fan in your case, and it's at the back, I'd say it was an exhaust.

Hold a sheet of paper at the fan and see if it gets blown away, or sucked in.
 
the best arrangement for fans in a standard ATX case, which that looks like, is intake low and front, exhaust high and rear.

Someone might correct me on this, as i've never had to use one, but I thought the best way to use a side fan is blowing into the case -unless its REALLY close to your heatsink and would then work against the heatsink's fan. Used as an intake, side fans give a bit of flow to your cards, and a bit of fresh to the heatsink.

I've always set up pcs so there's more extract than intake (negative pressure) or the extract/intake are very close. That fan grille on the back of the case is really restricting airflow.

e2a: had a better look at the pic, you don't have any intake fans if your side fan is used as extract - your intakes should be at the front in front of your hard drive.

used the paper method, the fan is so quiet and soft I could barely feel it with my hand but the paper showed me that the side is the vent intake and rear is the exhaust.

thanks anyway folks for your input ;)
