Concerns:
I don't think they are normal values...
What do you guys think?
I haven't tested it on Windows. I'm assuming the results will be the same?

Do you have your own water cooling loop
 
I am running 5.3Ghz 7700k (granted i won the silicon lottary) and after 2 hours of 800% cpu not exceeding 75C with the Corsair H115 however i added 2 x ML140 fans, I see nocturna fans talked about alot

I would also suggest forgetting about push/pull and contrary to conventional thought exhaust through the radiator yes the air being pushed will be a few degrees higher but to get the hot air out of your case is the goal

http://www.corsair.com/en-us/ml140-pro-140mm-premium-magnetic-levitation-fan

p.s then for shits and giggles i underclocked my chip to 4GHz, ran 800% Cpu and I have my idle rpm set at 900rpm which is in-audible and the cpu after 30min had not exceeded 50C which is where I have my fans set to spool up. I was more impressed with this then the 5.3GHz

600Q case granted but filled with ML fans and i'm happier to run at 4GHz then 5.3 and have a silent box

Is common knowledge that 7700K shouldn't be overclocked as per Intel guidance which is stupid. The whole idea of buying a K is to overclock it. When I got my 7700K I knew about the overheating issue but it was only $10 difference so I just got this. Intel dropped the ball big time on this one

Thanks for the info!
 
OP have you updated your BIOS? There was a known fault. They stuffed up the voltage values on the auto clocking for Kaby Lake and it runs way too hot.
What version is yours now?

No wonder, that heat sink is not meant for overclocking an i7 to those frequencies. It only weighs 480grams. Go get yourself a CPU cooler with more mass and 140mm fans. The greater the mass the greater the heat transfer is.

Noctua NH-U14s (770g) or NH-C14s (820g) would be much better! If you have the space go for even a NH-D15s (980g).

Edit: I have the NH-C14 and my i5 6600K @ 4,5Ghz never goes above 50-55°C with the fans at 25-30% speed.

How is your case ventilation set up. Enough air intake / exhaust?
 
Hey,
are the temperatures of hwmonitor the real temperatures of the sensors, or are they just calculated by cpu frequency and usage because I tried it and with the fakesmc-plugins the temperatures went up and dropped down really fast and were totally unreal

(this was in the intel power gadget too)
