i have a amd 8120
i installed a new cpu cooler today the corsair h100i it works fine.
after i have been playing games like bf3/4 the first few minutes are fine and
smooth but then after that all 8 cores max out at 100% and the game becomes unplayable and laggy
is there any advice
i did use 99% isopropanol alcohol to clean my cpu could that affect it this way
