lol @ chalex's doom guide :P

1 of our pcs downstairs was running for over a year with teh fan not plugged in for the processor and the heatsync alone was enough to keep it from overheating :P - and if anything does overheat they all have a built in cutoff that will shut down your pc if they go over a certain temperature. also remember that the graphics fan may not spin after you first turn on teh pc as some dont spin when theres no load - and if you buy a retail processor you dont need to bother with thermal paste yourself as the heatsync will come wiht it pre applied.
