Now I don't know very many details about this, but it's pretty interesting. I have a friend who uses a phase change cooling system (not sure what kind) that normally runs his P4 machine at around -45C. Well a few weeks ago, he OC'd everything to the absolute maximun and his CPU is supposedly running around 50C with load now! I haven't seen the machine, but I believe him, since he's never lied to me before. But how could you possibly generate THAT much heat OCing?! He's either lying or he's running an insanely unstable machine. Supposedly he got his graphics card running at 300% stock and got somewhere around a 60-70% increase on his CPU. I find it very hard to believe, but very interesting if it's true. If it is true, I guess that's he's real close to the record for an OC with his model of CPU. Don't really know. I'll see him again in a few weeks and see if he can hook me up with some pics/screenshots.
