For anyone that still cares, I have my 1045T running 3.6GHZ stable @ 1.275 volts with this same motherboard. The bus is running 267MHZ and HT Link 2403MHZ. I am using a Hyper 212+ with the stock Push Fan and have a 120mm case exhaust fan. It idles at 37c and never goes passed 53c on full load (prime95 and linx at same time). If I try to push the chip anymore the mobo downclocks it, I think the VRM's are getting too hot.
I've prime95 and linx 50 loops at the same time with no issues.
