Im getting a QX9650 tomorrow and i dont think my CoolerMaster TX3 with Arctic Cooling F9 Push/Pull will handle it at 4.0Ghz. If i get a Coolermaster Seidon 120V will it handle it at 4.0-4.3Ghz?
It is all up to the silicon lottery.. If your cpu has good silicon and low temps you may hit above average speeds.. Till you test it only stock settings are certain..
