with my macbook the fan is on quite a bit, and the bottom gets really hot, is there any hardware mods that i could do to make it run cooler? kinda like with xbox 360, you can do the x-clamp fix and it runs cooler....i know theres apps to change like the speed and hw often the cooling fan turns on and off, but i wanna make it run cooler(i wanna try and make the fan not come on as often, or not stay on for so long)
