I use Coretemp for monitoring all 8 cores on my AMD 8 core CPU. I was just sitting there on facebook, cpu % at like only 1-4%, at like 25c. Then, randomly, it said core 7 was critical even though it was at 27c. Should I be worried? Note - I just started using speedfan and have the cpu fan at 50% load and 50% idle. My idle temps are around 20-30c, and load temps are about 55-65c. Should I worried?
