sweet, i like that program for graphing the heat. i just use a CPU heat gauge widget to check mine. Usually it is the highest right after i play some UT2k4 (around 68c). i wouldnt worry too much about 70c, 80 is the melting point. i dont know this for a fact but i think it will be ok up to about 74c after that it will probably get unstable and shut itself off before it would really overheat and get damaged. anyone want to test this? yeah i didnt think so.
