I have a Core i7 7700k with a Hyper 212 LED cooler and a Gigabyte Z170X Ultra Gaming motherboard. At default motherboard settings, with no overclocking whatsoever, I'm getting temperatures of 95C when stress testing using Ubuntu's "stress" package. I'm pretty sure prime95 would have overheated my CPU, because it's a more strenuous test than "stress".
I then set Vcore manually to 1.2V and ran prime95. It crashed immediately. 1.225V was also unstable, with prime95 crashing after 6 hours, but 1.235V seems stable. The problem is, I'm getting an average temperature of around 82C with Prime95 at 1.235V, with rare temporary spikes up to 86C and dips down to 75C. With Ubuntu's "stress", I get temperatures of 77C; with ordinary programs that still use 400% CPU, I get a very reasonable 68C.
I have hyperthreading disabled, XMP enabled (@3000 MHz, with Profile1), and a manual Vcore at 1.235V, but everything else is default--Turbo Boost is enabled, C states are auto (I think), etc.
My question is: are these temperatures and voltages reasonable for stock? 1.235V and 82C both seem too high for stock frequency.
