did u try other temp monitoring software? CPU Temp or Speedfan? i wonder if its an erroneous reading or the software is incorrect.
Thanks for the consideration - I did us speedfan and today the startiup temp2 (at room ambient of 83F) is 53C (my GPU is 51C but I haven't seen it exceed 60C). I've been running a Flt Sim (fairly heavily loaded) and temp2 is up to 79C and climbing slowly.
