I still using my old cm330 case and Q6600@3.2ghz with xigmatek achilles cooler with cpu idle at 48/50...is there anyway to drop the temperature

Load temps?

65c

65C while doing Prime95?

Your vcore how much ? I'm using Q6600 as well yet clocked at 3.1ghz only . Idle around 39C while load 57C

65c is with just occt or dirt2 + wprime and the 3.2ghz is at stock voltage VID1.325

Your temp is perfectly fine with the vcore . You can try Linx which I think it make truly 100% stress your proc and hence getting the highest temp of your proc .

thanks for the answer^^..but do you think I can lower the temperature even more if upgrade the to haf 912 or 690 II case...since my cm elite 330 don't have good air flow..even the HDD is 40c

Wrong place to ask. Thread moved

Yes for sure . More air hole and fan = more fresh air and better temp for sure . Since you already hav a aftermarket cpu cooler , it is a good choise to change for better case .

recommend u cm 690 II advanced

temp wise, not much u can do bout it
u can try lower the vCore cause i think 3.2 dun nid that much .
mine last time 3.6 required 1.45v and it loads around 67C on WC

its still in the safe zone so no worry .
get a better casing for better flow .

I nt sure how much is mine to go 3.6 . But currently using 1.275vcore at bios to achieve 3.1ghz

haf 922 or 932 are good cases IMO. bigger space that can accommodate almost anything (of course except SR-2), and has a good cable management at the back of the mb tray.
