I also used AMD Overdrive. But did not notice any of the extreme peaks in temp there. I alsi thought the cpu would be broken if it really had reached that temp.
It is a amd fx8350 chip and a asus m5a78l. I have been testing it with this new cpu for about a week and only just started getting spikes in temp in cpuid hwmonitor.
I left it running so did not actually see the peak in temp, i just saw it when i loomed at the cpu min max temps.
In bios the temp was normal when i looked, about 40c, but like i say i did not witness the rise in temp from the usual 40c to >100 >200c just the max temp it recorded but only in hwmonitor not amd overdrive. Dont know whats happening!
Thanks fir all the help n advice much appreciated.
