OK this opinion is not very popular but I had a similar issue with a FX-6100 with stock cooling; everybody recommended me to upgrade the CPU cooler but the options seemed bad quality unless I was willing to expend 90%+ the cost of the CPU itself which seemed just illogical, I went and tried to keep the case fresh instead and worked like a charm and all it took was three 120 mm fans well placed (2 outakes in the upper part, one intake in the lower part, my cpu rarely hits 60 degrees on full load. How ae you cooling your case?
