I recently upgraded my CPU from 720 BE to 955 BE. I'm using an Arctic Cooling 7. With my 720 BE I idled at 23'C. With the 955 BE it idles at 43'C and while running prime95 it sits at 58'C. The only thing that changes is I bought and applied this thermal removal and purifier from Newegg. http://www.newegg.com/Product/Product.aspx?Item=N82E16835100010. What do you all think?
