Yeah It's mounted right. Remounted twice and the contact patch was good both times. The chips idles at 48-50C with 4 cores at >1.3v . Don't know how high the temps get because windows locks up. It's an old skt 939 era cooler but it keeps my x3 720 at 35-38C idle and 48-50C load. With 2 cores it doesn't go over 45C at load. I was planning on getting a new cooler anyway so I guess I'll be looking for something tomorrow.
