I couldn't be more happy with my Ultra Extreme. It beat my Tuniq in both idle and load temps and I'm finally able to do 3.6GHz w/o breaking 60C full load (55-57C after 2 hours @ >1.48V (~1.43-1.44V BIOS)) using OCCT @ 75-77 ambient.

I would definitely check the flatness of your IHS and make sure you don't over due the thernal paste or, better yet, get yourself some liquid metal and .
Well I got say this Ultra extreme is pure crap...
I have L47G that I ran on water in main box, with setup in my sig
3500 @1.525v I would have a delta of 20C..loads in 58-60C on Prime

So I know the IHS is pretty good

This Ultra extreme twists easily sideways...I have the screws as tight as they will go....3420 with 1.48v idle at 40C....load shots up to over 65-68C in like 2min on Prime95 and system reboots....
Moreover the heatpipes/bottom of the HS is not getting warm as if there is no heat transfer

Any suggestions on how to get this thing to work...I am not lapping it.. Iwill send it back for a refund before I do anything...no way I should have to fix a HS....garbage
