yeah, i couldnt go past 891 on the core clock without upping the voltage. my temps are actually better now than they were with the overclock i originally posted with lower fan speeds. In battlefield 3 mp, it hits about 83 at around 60% fan speed, but bf3 is the worst, alan wake, nfs the run etc, run at about 68 degrees at around 50% fan speed. thats not pushing it to hard is it? i wouldnt go any further.
