I curretly have an acrylic case with five 25mm fans, and an aluminum heatsink fan combo (stock). My Cpu is usually running around 135 ferhenheit. And the temperature in case is at 100-98 degress ferhenheit. Everything is running pretty well but i dont think that my 3.2GHz p4 is running at full capacity, I beleive that it is due to the heat. Should i think about upgrading my heatsink to copper and get bigger fans?
