4850 in there...

fan under my PSU that blows air out to the back...The fan there at the back is a 80mm (exhaust), and my CPU fan sucks air in.

Now, should I buy a fan and put it in here for intake...(bottom front of the case...80mm max, cant put a 120mm in that spot). It blows are directly under the 4850 --> [------card------] <~~air~~ [fan spot]

Or put one here...(side panel) blowing air in as the CPU fan sucks air in (like i said before). BUT, the 4850 blows air out from the copper side bit (as you can see in the photos). If you think I can't put a fan there because there are no screw hole/mount, well, I figured out a way


So should I put it at one of the spots, or at both locations....not sure if it will cause any air intake/exhaust problems (turbulance? i dunno). Oh yeah, My PSU has ONE "case fan only" cable that allows it to control a case fan's speed.
