I shudder to think how hot it would get with a P4 system rather than my X2.
Oh that is such a load of BS, and not just because of your exaggerations. We have labs of prescott P4's and celerons at work... and the monitors (15 and 17" CRTs) give off a lot more heat than the computers do.
Another load of BS.
Who's exagerating? I'm cursed with a heavy build (and a couple of pounds i could afford to lose) and a tendancy to sweat. The temperature rises notably when the computer is on. You open my door and get a blast of cool air from the rest of the house.
Now, my room is aproximatly 4m x 4m x 3m, that works out at 48m^3. The SHC of air is roughly 1 and the mass of air is very roughly 1kg/m^3. That means to raise the temperature in the room by 1*C you need to put in an additional 48000 Joules of energy.
As you know watts are joules per second, so a computer idling that draws 75W will take 640 seconds to generate enough heat to raise the temperature by a single degree. 10 minutes (edit, ok closer to 11).
Of course that heat is being moved elsewhere by convection currents in the air, but unless you have good aircon it'll warm up the local area quite a bit.
