Wheels, nice clock and temps. I assume you're using 95 as TJMax for Coretemp? What was the ambient temperature at the time of that screenshot? Is the CPU the only component in that loop?

My temperatures after about an hour of Prime are very similar to yours, except with the overclock @ 3.6GHz. But I am running a dual rad, not a triple. I imagine if I ran a triple, I would be mid 40's at 3.8Ghz.
