I'm building 2 i5 6600k's. This is my first one, the other should be in a month or so. I was going to build a i7 6700k for myself, but I killed the chip trying to naked mount it, I think the PCB is too thin and it flexed, breaking some bumps or something. EK's website and facebook both stated their kit would support the 6 series, then edited their pages to say nevermind. Even with the cap on, it is dead, tried in 2 boards, so I naked mounted my 4790k and will keep it another year, it did drop my temps 10c vs the delid, clean up, re-lid method. I'm not salty over this (besides the editing of their "support" of the chip), in my 20yrs of building PCs I have now killed 1 chip, and 1 board (replacing a DFI-SLI NF4 chipset fan), so I am ok with that track record. I was upgrading a friend from a C2Q, was going to sell him my 4790k/board/ram, bought a 6600k instead and he gets my new board/ram.

On to the meat of this post:
I am very surprised how cool this chip ran, temps were not a factor, I hit a wall at 4.9ghz (with 1.4v or 90c being the max I want to run). In hindsight, I could have maxed out the 6700k without deliding.
I set him up 3 profiles
-Stock clock
-4.6ghz @ 1.385v (normal use)
-4.7ghz @ 1.400v (benchmarks or the "look at me" clock)
I didn't take a shot of 24hrs but here is a shot just so you can see it is stable and how low the Linpack temps are:
