i recently came across a HUGE fan. it is about 8 inches in diameter. i wanted to put this on the side of my pc case. my question is should have have it blow air in, or blow air out of the computer? thanks

Depending on the location of the fans you could create a decent air flow over
your hot spots with one in one out. I suggest blowing out however.

Really? I would think that would be bad as it would just blow the hot air onto the motherboard. If the fan was below the graphics card that would be even worse.

If it's going on the side I would say exhaust.

no, because ambient temperature is cooler than case temp. so if he sets the fan as intake it will help cool the components.

it would also depend on what component it's closer to. i had a cpu fan that blew air away from cpu (stock fans blow air towards heatsing/cpu) in that case an exhaust would help get rid of warm air. but if using a stock cooler or any variant that blows air towards the cpu, then the side fan would work best as intake.
if it's closer to video card, i think it would be better as intake as well.
 
Hot air rises, Exhaust fans should be over half way up, intakes in the lower half. The Video cards fans are intakes, the fan would supply cool air to it plus blowing cool air on the board.

If you put a big fan like that on the side or any fan in my opinion as a exhaust in the side, it will fight the back exhaust - CPU fan and top fans if you have them for air. Starving them all somewhat.

...What? Air outside the case is usually cooler...

No, I meant as in removing the hot air as opposed to bringing in more air. I learned this when I switched around the 120mm fan in my old case and my gpu temps raised by about 10*C. This may be because my 8800GT is single slot cooled. Anyway, I have the fan pulling warm air out instead.

I suppose I'm not making much sense today. :(

Odd, ive had better luck with positive pressure vs negative, then again in my case positive pressure is two 250mm fans lol. Only have a 120mm and a 200mm exhaust and my ambients are around 18-19c
 
Generally bottom/front/side intake, rear/top exhaust, side fans over a GPU are generally good so they push cool air into the GPU fan, only if you're lacking exhaust should you use the side as exhaust
 
I would vote making it an intake fan. Not only do you get active cooling blowing on all of your components, but you get positive air pressure inside the case. This helps to keep out dust, assuming you have filters on the other fans. The positive pressure allows air to blow out of the unfiltered ventilation holes in the case.
