Btw, "VRM" is a terribly vague term. It doesn't mean any specific component exactly. What you appear to refer to is the Vitec/Pulse inductor-pack that has a maximum operating temperature of 125ºC. They wont break immediately above 125ºC - their performance simply goes down the drain. The actual voltage converters the temperature readings in GPU-Z come from are the little dark grey rectangular chips and their max operating temp is NDA protected data so one would be well advised to keep them way below 100ºC...
Largon (or anyone else) I'd love to see some documentation on all the chips on the 4870 - which chip does what, which get hot (and therefore need cooling), etc. Anyone?
