Heat problems are not limited to operating temps. If your fan fails or if the heatsink assembly comes off, in oh lets say transport, there can be some PROBLEMS. Its called CPU suicide, even tom makes note that improperly seated heatsinks or fan failure can result in a dead cpu in seconds. And since I like to attend LAN parties and move my computer from dorm to house over breaks there is a possiblilty that the heatsink just might come unseated. Not to mention my prior luck with AMD wasnt the best, Ill stick to Intel. And call me an outcast but i dont see the need to OC everything in my damn computer. I drive 300ZX Turbo, doest that mean that I have to drive it at its absolute limits? No, but it is fun to take it out and see what it will do every once and a while. Thats the same way I see overclocking.
