Temps are pretty good. It might peak at 53C. But I have to repaste, because I took the cooler off 3 times when I was troubleshooting the new RAM. The cooler completely covers the last slot. I have some Conductonaut liquid metal left over, so I'm going to put that down and see what happens.
I have it at 4GHz. I tried listing that in the details, but it kept switching back to 3.7. :P The good thing is that I only have it set to 1.2625V, and it is perfectly stable. So I have absolutely no worries about longevity.
