Most folks recommend getting the Zalman 7000 series heatsink, but they are huge and more importantly weights a lot. It just seems like it may damage the cpu (if it goes off its mounting) if it were used in a lan party pc where it may get lugged around. Does anyone recommend a much lighter heatsink that work as well or almost as well (light enough that if you move the PC regularly, it won't damage the cpu?) that's equally quiet?
