Jut an FYI... Any Processor CAN run without a fan. Case in point. I'm currently banging on a stock Compaq Deskpro with a slot one Celeron 400mhz. No fan at all. The heat sink is large and the case is large but, the heat build up is not bad at all. BTW. The users here love them because they are soooo.. silent.
