I have my i7 920 OC'd to 3.65GHz on 1.23125vcore. The vcore itself seems a little high for only 3.65. Coretemp and speed fan are reading 75 degrees celsius with prime95 running for about half an hour now. I have the Xigmatek Dark Knight HSF and a Lian Li PC-6070b case. I've tried lowering the vcore and using different bclk multipliers but to no avail.
