Hey guys. I am stuck here waiting for a 2 min. HD YouTube video to encode, easy task right? Wrong. My MacBook insists that it needs to get it's one little fan spinning up over 6,200 RPM (making an annoying sound) to cool down it's 2.0 GHz cpu. This is seriously bugging me, and I want a way to keep my MacBook cool, but without all that annoying whirring. What I'm looking for is a case or something that will get more airflow going through the mac, keeping it cool enough to watch a movie on without it getting it's singlr fan up over 3,600 RPM. Do you know of anything to buy, or any DIY ways to give my setup more robust cooling? (This is my only comp, so it's basically a laptop/desktop for me.) Thanks.
