decided to throw a 60mm case fan in my 360, for additional cooling. you could call it a supercharger i suppose. it's pulling air directly from the outside of the case and blowing it on the heatsinks for the cpu and gpu, then through the shroud and it's being pulled out by the factory fans. figured my 360 already red ringed twice, so i'd try and extend the life a bit more. and i got the fan for 2.84 shipped, so it's a win win. modded the outside of the case to allow the fan to pull in air, will probably add pix when it's painted up.
