The temperatures during overclocking for the Intel i7 7700k are excessively high.
I attempted to boost my processor (Intel i7 7700k @4.2Ghz) to 5.0Ghz, reaching a stable overclock of 5.15Ghz at 1.35v. However, the Cinebench r15 results show temperatures around 88°C. I considered lowering the target to 5.0Ghz but still saw temperatures near 87°C. With a Kraken x62 AIO water cooler, I’m unsure if voltage settings or cooling performance are the issue. My idle temps range from 35-40°C and ambient stays between 20-24°C. I expected better results initially, so I’m questioning if the cooler is faulty or just less efficient.
Voltage plays a major role in generating heat. If you have a strong overclocker, try setting it to 1.3v. A few users achieved 5Ghz at just 1.28v, which is quite impressive. The key is your 5.15Ghz performance at 1.35v is excellent, with the top being around 1.33v. For more details on clock to voltage settings, check this guide.
Voltage is the big heat maker. It sounds like you have a good overclocker so try 1.3v. Some have hit 5Ghz on only 1.28v which is about the best. Point is your 5.15Ghz at only 1.35 is very good with the best being 1.33v. Here is some information on clock to voltage.

Great work, man, the overlock is fine. You can adjust the PLL OC voltage to lower the temperatures, though it looks like no one has confirmed if this is effective.
Here are the mines after the prime test at 4.8ghz. At 5ghz it was just a few degrees higher, but I'm worried they might not be real.
Using Kraken too, three fans consume about one exhaust.
