Not too worried about a silent PC, but the seller said the machine was noisy so the fans might just need lubed, replaced, or he isn't used to a windtunnel mac.

I assume the fans might be controlled by a sensor monitoring CPU temp and the CPU heatsink might be clogged with dust or they used too much heatsink compound on the CPU and it has dried up causing them to overheat. Will find out when UPS gets here, I strip my machines when I get them anyway to clan them and look around so I will see whats up.

I will probably just keep my 1.25Ghz QS in my room, that machine is quiet enough to leave running.
