I've currently got my 3960x @4.8ghz with 1.45v (as far as I'm aware, that's not a crazy voltage for X79, but I stand to be corrected).

It reaches 70C under full synthetic load (aircon in room -cheating?), but doesn't go above 60C in games.

I'm having trouble getting the clock up to 5Ghz with a 50x Multiplier under voltages I'm comfortable with.
Anyone with experience with this CPU/Mobo with a few pointers?

I'm running a Corsair TX850W PSU currently - whilst a bit old, Johnnyguru gave it great review.
