i7 7700k was overclocked to just 4.7 GHz. With the enermax liqmax ii 120 liquid cooling system installed, I experienced temperatures reaching up to 94°C during games like DayZ and streaming. I stopped playing right away. It seems the thermal paste is working well. The worst part is that my PC didn’t shut down on its own.
I suggest you slightly lower your overclock along with the voltage, assuming you've increased it as well. It's enjoyable to experiment, but it becomes too hot for regular use. You might discover that even 4.5 Ghz runs significantly better. There comes a limit where adding more voltage and boosting clocks causes the CPU to consume far more power and produce excessive heat.
Dennis_4 shared his experience with an i7 7700k running at just 4.7 GHz, using a liquid cooling system. While streaming and playing games, temperatures rose to around 94°C, causing him to stop immediately. He believes the cooler is handling it well. He also mentioned that his PC didn’t shut down on its own, suggesting possible thermal issues. He advises against overclocking by hand and notes that 95°C is usually safe, though close to the limit.

Notice that a 120mm CLC style cooling solution such as the $60 enermax (Corsair H55) isn't quite as effective as the $25 air cooler (Hyper 212). Nonetheless, I still think there might be an issue with the mount or the CLC. The 5.0 Ghz frequency shouldn't be a concern with the 7700k. Could you check the core voltage while running using HWiNFO and sensors only?
You seem to have had some bad luck with the bin, or your cooling system might not be working properly.
Four out of five will function at around 4.9.
Any cooler, whether liquid or otherwise, requires a supply of fresh air to operate effectively.
What is your situation? Where is the cooler installed and how is it mounted?
Some liquid cooler mounts can struggle to apply enough pressure on the CPU die for a proper seal.
The shutdown temperature approaches 100°C.
