Windogg,
You are right...
A good friend of mine, and a member of AT, didn't seat a peltier on his 600mhz well enough. After a bit of OCing, he couldnt figure out what was wrong with his box, so he checked MBM and it read his CPU temp at 220F. His CPU was doing an impression of a lightbulb... the bastard then tried to sell his burnt up CPU to me... what a friend!
If you plan to run your CPU stock, I don't think it matters much where you get it from. I'd look for quality if you plan on OCing, and for that I'd get it from manufacturer.
