I am about to upgrade and add some fans to my system and I was wondering how it worked. Fans like my CPU and Vid Card fan, do those blow toward the chip or do they take air away from the chip? I tried sticking my hand infront of the chips but I can't tell where the air is coming from.
Furthermore, cases that have fans mounted on walls or top, is that like an exhaust system or is it actually sucking air in? like so: http://lib.store.yahoo.net/lib/xoxide/clear5.jpg
And on a regular computer with only the fans from the psu, cpu, vid card, the air comes in from where? and then gets flushed out the psu right?
Thanks, just trying to understand the air flow before I go upgrade/add fans.
