It's not I wanna tell you it's that temp it's that temp.
And yes they are both in celcius, These are old school celerons from the good batch that run at well over 500mhz.
Just goes to show what a case fan can do, considering the fan on the linux cpu doesn't spin, where the windows machines case fan is toast. =P both are open case stuffed under a dusty desk.
Windows is a resource whore, theres just to much you can't do(read: turn off). code is code, when it gets down to it it's the same instructions, you can't argue the linux kernel has more overhead then windows, you can argue gnu lib bloat and we can go on an individual basis if ya want =)
But I'll refrain from MS bashing, because if nothing else we owe them for the 500$ computers. Really when it comes down to it it's the same instructions, if the heats high there should be some serious work going on.
Oh and the excessive heat in the windows computer is probably the 4 harddrives bolted to the bottom of two cd burners... Mmmmm toasty
