I have a fx 4100 which is bottlenecking my gtx 960. So I OC it to 4ghz and now there is a vast difference in performance and max temp is 65c on stock cooler. But if I OC it to 4.2ghz I get even more performance but the max temp rises to 82c. If I buy the evo 212 cooler how much OC will it withstand and what will be the max temp?
