I know this is a long shot, but I now have a DQ6 and E6600. I'm raising my FSB 10Mhz at a time, and now up to 370 (3.33 Ghz) w/o a hiccup. I'm running Prime95 and SuperPi (32M) concurrently (till SuperPi completes) for each stress level. My CPU is just starting to creep into the 60s at 370 with stock HS anf fan under that load. Chipset is fine at 30c. The Gigabyte S/W fan control is disabled (for some reason!), and the fan is only running at 1800 RPM max - I think the 100% is around 2400 RPM. Tried Speedfan, no luck there. So the question is - why would the Gigbyte fan control be disabled? I have the fan control method set to Auto/Auto in BIOS. I'd like it to run at full thottle above 60c. Any insights? I have BIOS F5 (not quite the latest). And BTW, I LOVE THIS BOARD (so far).
