Hey, you could be even worse off. My 6700K runs with ~1.3V at 4.4GHz, getting it stable at 4.5GHz requires about 1.4V. I can get it to boot at 4.6GHz with 1.4V, but I don't even want to try to get it stable at that frequency. Would probably need closer to 1.5V for that, and I'm rather certain I'd hit thermal throttling limit (100C) when trying to launch a benchmark then :-) It's worth noting the CPU's VID values fluctuate around 1.35V - 1.4V with the 4.4GHz OC. Looks like Intel actually measures their chips pretty well before shipping.
4.4GHz is the sweet spot for my chip it seems, the amount of extra voltage required for the next 100MHz is rather excessive. For daily use I have set DVID -0.035V at 4.4GHz, it keeps it nice and stable (used to have -0.050V, but running AVX prime95 for several hours caused a crash so I bumped it up a bit. Been working just fine after that.) - VCore with this setting fluctuates around 1.28V - 1.31V during heavy use. My motherboard is sort of a feature reduced version of a mainstream OC platform, Gigabyte GA-Z170-GAMING K3-EU. It suits my needs (although in retrospect I should've just paid extra ~30€ for one of the flagship motherboards, even though they tend to come with about a million unnecessary features)
Temps in non-AVX heavy use / torture applications stay generally just under 70C or at the very most in low 70s. In AVX applications we cross the 80C line, hours of Prime95 small FFT torture will get it close to 90C, but for example Folding@Home with a work unit utilizing A7 core only ramps up to mid-80s occasionally, and generally stays just around 80C. In my more usual gaming scenario core temps rarely go above 60C for longer periods of time. True idle temps will stabilize just a few degrees C above ambient, generally under 30C (waiting for that summer heat wave...). With usual background activity (read: cookie clicker on firefox) idle temps fluctuate roughly between 30 and 40C.
The system is air cooled, CPU heatsink used is Thermalright's Macho Rev. B. Case is a Fractal Design R5 - I really love the acoustic padding around the case, makes my machine run rather quiet even at full fans.
