Your temp reading is off. I have the same board as you and I am running 1.35 max on load on the 1950x to get 4 ghz stable. I have a 480 hwlabs gts with a d5 for the cpu loop and 4 ml120s on it (one of the best fans out there atm in terms of performance). It's odd that your showing such a low temp something is definitely not right. I would try flashing the latest beta then doing a cmos clear and re-entering your settings.
I'll try giving it a go later (although I flashed this bios not long ago and did a cmos clear at that point) - out of curiosity what are your idle temps?
