They talk a lot about "stable" overclocks, but I wonder, just how hot are these suckers running? They never actually show the core temps for their quads. lol they're probably around 80-90 degrees C. Whether it is stable or not, it wont be forever at that temperature. And if any little thing goes wrong with your setup, there is no tolerance for it and you could be out an awful lot of money. Like that bridge in minneapolis...
Seriously, you people thinking about buying a Q6600 to overclock it, you better understand that you will be pushing some seriously high temperatures inside the cores, even at stock speeds. Under full load, my cpu temp sensor reads only 49C, but my core temps are up over 68C, at stock speeds. At 3GHz under full load, my cpu temp sensor reads 54C but my core temps are up around 85C. That's scary hot! I can't imagine it lasting very long at those temps. But what should be of greater concern is the sheer number of times the CPU will be forced to run that hot, and then relatively cooler when idling, then super hot again, then cool, etc. All I know is I'm not using my cpu to find out how many times it can take that before it breaks. That's what Tom's hardware is for! They need to get on it!
