Advice on 8700K High Temperatures Under Stress Testing
I know this is a question that has no doubt been asked many times but if someone could put my mind at rest I would be grateful. (BTW this is not a PC I've built, someone was selling it locally and I got a good deal on it. Previously had not been overclocked.)
So I've just been putting a mild overclock on the CPU and found a stable setting running @ 4.7ghz with 1.280v. Ran OCCT stress test for 4 hours with no errors but temps peaked at 93 degrees (Celsius) and most of the time sat between 70-85. Idle temps peak at 50 but most of the time sit at 30.
CPU fan is running at 500-700rpm during idle and hit just under 2000rpm during stress test. All fans set to auto configure is bios.
I know that this cooler (see below) is a limiting factor and 4.7ghz is the top end of what is safe to run. Also I know this case is thought to not have the best air flow by some. I have two intake fans and one exhaust installed.
Ambient temps are quite cool at the moment (live in the UK) but will increase when summer arrives.
So question is are these temps acceptable or should I reduce the core speed by 100mhz and dial back the voltage a bit?
Thanks for any help or advice!

The maximum height you can achieve with a chip is influenced by three factors.
These include the quality of your chip, the performance of your cooler, and the voltage you can handle.
As of 3/22/2018, the data shows specific percentages for I7-8700k chips under certain conditions.
I've adjusted the core speed to 4.6ghz and slowly reduced the voltage to 1.16. Running much cooler, with maximum temperatures reaching 81 under stress. Think that's a solid approach.
As a relative newcomer to OCing, I believe I've gained more by fixing issues myself and steadily achieving stable speeds and temperatures.

Hey thanks for your reply.
The cooler isn't the best, but it's okay for my needs. I wasn't looking for anything faster—I just wanted to explore what I could get with what I already have.
I've picked up a lot about OCing in a short time. It's not about chasing numbers, just trying to future-proof things as much as possible.
Interestingly, the build I had before was similar to yours. I stripped it down and sold everything, but it seems that case was more efficient than this one I have now!
