I replaced my stock fan for i5 3570k with an evo 212 hyper, my idle temps did not change. I then overclocked to 4.2Ghz and max temp is about 64c- 70c after gaming, have I fitted it properly? I only ask because I read reviews of people seeing the idle temp drop after installation. I know idle temp means nothing but I just want to know if I fitted the Evo right. Thanks
