OC-ed my i7 6700k, temp at 80C
I upgraded my i7 6700k to 4.7ghz with VID 1.355v and 1.375v underload. During benchmarking with AIDA64, temperatures reached up to 85°C. When playing games, the highest temperature recorded was 77°C. I'm using the Hyper 212 evo at stock clock and voltage. Are those acceptable temperatures? Should I reduce the clock speed at bit rate?
I believe the chip performed better than expected.

What percentage can achieve an overclock with a reasonable 1.40v Vcore?
I7-6700K
4.8 18%
4.7 56%
4.6 87%
4.5 100%
Maintain vcore below 1.4v.
Temperatures remain acceptable during load.
The hyper212 works adequately, though not optimal.
It will suffice.
If idle temps sit between 10-15°C above ambient, the cooler installation is solid.
Apply speedstep and adaptive voltages.
This will lower voltage and multiplier when the CPU isn’t under heavy stress.
I’d slightly reduce the target; what’s your actual requirement?
Any cooler requires adequate airflow to function properly.
Leaving case covers off can significantly impact performance—be mindful of case cooling.
Intel advises a slightly reduced temperature likely. It's usually been around the low 70degC for recent models.
Throttling could reach about 100degC, but we're focusing on your CPU's lifespan.
Taking into account the almost negligible real-world variation, I recommend lowering to 4.5GHz and setting voltage as low as possible to ensure stability. Voltage is what mainly affects temperature.
I haven't experimented with SKYLAKE, but on my i7-3770K there were settings for adjusting frequency based on core count.
For instance, in Task Manager I found:
1-core: x39 (3.9GHz)
2-core: x38
3-core: x37
4-core: x36
I didn't adjust voltage and ended up with x43 for 1 and 2 cores, and x42 for 3 and 4 cores, never dropping below 4.2GHz (Task Manager showed 4.16GHz).
Speed step would fall below 4.2GHz for less demanding tasks to save power. I wouldn't recommend disabling it; I believe Skylake changed the name.
In your situation, which is probably a bit different, you might achieve a similar result while significantly reducing temperature and maintaining most performance—though this may not show much difference in gaming.
Update: The Intel CPU diagnostic (Intel site) seems to reset my CPU back to default without Turbo, requiring a reboot. This doesn't really confirm my settings. You could try Task Manager with the test running, or consider using Prime95 for confirmation.

Your temps are acceptable during load.
The hyper212 works, though it’s not the best.
It will suffice.
If idle temps sit between 10-15c compared to ambient, the cooler is properly positioned.
Apply speedstep and adaptive voltages.
This will lower voltage and multiplier when the CPU isn’t under heavy stress.
I’d ease back slightly; how essential are you really?
Any cooler requires fresh air to function optimally.
If you leave the case covers off and notice a significant impact, focus on case cooling.
I can’t enable speedstep; I’m unsure why my BIOS blocks it. I’m using an MSI z170A PC MATE.
