Which way should the wind blow?

[Brangwen]

I'm using a FOP32 fan/HS and Artic Silver II CPU grease to cool a 1.2 GHz T-Bird. My temps run from 30 - 49C depending on what I'm doing. A question for my colleagues: I have a front case fan -- nothing huge -- blowing at roughly 2800 rpms. I have it configured to suck air into my midsize tower. Should I instead be exhausting air out, allowing cool air to enter the venting on the sides of my tower? Or is sucking air into the case best?

Thx!

PS: Have 32 MB NVidia vidcard with small fan and 30 GB IBM 7200rpm ATA100 HD running as well.

Would be better to create a natural path since heat rises, cool fresh air in the lower front, then across all your heated up components resulting in the warm nasty air being pushed out the powersupplys vent, make sure your p/s fan is "exausting", some suck inward, in that case flip the fan around for better results...

Oh yeah it may be better to tape off some of those side vents to force your airflows pathway, make changes and monitor your temps as each situation can vary...ive cut 80 or 92mm holes in the caseside over the cpu--v/c along with an equal blowhole in the top for even more dramatic cooling, many have resorted to this simple method of added airflow... (easy for me as I have access to a Greenlee holepunch)

It wouldn't hurt at all to add an exhaust fan toward the upper rear of the case, this would increase your air a lot! Cool in at the bottom front, warm/hot out the upper rear.

Thanks a lot for your comments. Sounds logical to me!
