The temps on my 8350 are VERY strange. When its idle its something between 19 and 25-26C. Its going up and down all the time. When I am playing it can jump up to 70 and even 80. But thats not constant temperature. I am using CPU meter + Core temp to monitor my temps but I never experienced such difference with my old Phenom II processor. I don't know whats going on really. I am not using the stock cooler btw.
This is my cooler http://www.arctic.ac/en/p/cooling/cpu/15/alpine-64-pro-rev.2.html and yesterday when I was playing Red Orchestra 2 I got these temps http://i.imgur.com/RwE1x5T.jpg Should I must be worried?
