I've been hanging out here learning for the last couple of weeks before attempting my first OC. Had everything running pretty smoothly at about 42-44C idle, 49C loaded (measured with MBM). I replaced my original HSF (a big generic aluminum thing my local vendor sold me) with an Alpha PAL 6035 with the standard YS Tech fan and Artic Silver and my temps actually went up! I took the HSF off and cleaned the base and the core, and reinstalled with new Artic Silver, and I'm still getting 53C idle. The fan is drawing up through the HS as Alpha suggests. My motherboard temps are ok, I think, at around 30C with a big 120mm Panaflo blowing in on the board through the side panel, and an 80mm blowhole fan on top. This seems too warm to me. Things are stable but I'd like to push it further. Any advice for this new OCer?
