I got my Fx 6300 a week ago and I oc it to 4.0 Ghz with stock cooler,was playing BF3 for like 2h max temp was 57 on cpu and around 50 on socket.Btw Fx 6300 gets hotter on stock.on stock his voltage wen under heavy load 1.475 that is allot for stock.My OC to 4.0 Ghz is at 1.25 v and runs cooler and better.So if u have good mobo just OC it, it is rly easy.u can set all votages on auto and offset mode manual set Ht and NB to default and RAM and bump ratio to 20 and there u have it nice littel OC and u will see performance gain.Best of luck.
