I have a P4 2.4B overclocked to 3.0. It works fine with the stock Intel heatsink and fan, but if I stress the cpu (like encoding a DVD) the temperature gets up to and slightly over 60 degrees Celsius. I was considering getting an Alpha or a Swiftech heatsink to bring the 100% load temps down slightly, but I wanted to get some suggestions from you guys first. Thanks for you help.
