CPU Temp.

Interesting....
Looking at the CPU temp this am it was 121f.
Not bad...but a little toasty...so I pull the CPU, blow out the heat sink and new CPU paste.
Fire it up and start windows and log on the web....wow! jumps to 136f!
Restart in linux...log on...check temp...109f. hmmmmm...........

Always thought Linux was the cooler of the two.

'cause when things get warmer...they get bigger. Electrons are the "things" I am referring to in this instance.
As electrons move thru a conductor...your CPU has many conductors...the friction of that movement creates heat. As things heat up the electrons movement is inhibited and move slower...hence the "actual" speed is slower, but power consumption is greater.
This has nothing to do with the frequency (*hz.).

My point was...the difference between loading lin and windows created a temp. difference of almost 20 degrees.
One could extrapolate that it takes around 20% more power to load win than lin.

Actually, it doesn't have much to do with CPU load differences between Win/linux :). Linux sends HLT instructions to the CPU, effectivelly turning it "off" when it's idle. Windows does not incorporate that code (actually NT/W2k does). That's why those CPU "cooling" programs like "rain" work.
