Hi,
my i7-8700k OC to 4.9ghz with custom waterloop CPU and GPU, the CPU temperature fluctuates up and down every second during the stress test, between 65C to 85C. Is this a waterloop issue or just normal behavior?

The 8700K fits into the silicon pool like the rest, but you'll need either to desolder it or get improved cooling for the CPU to achieve higher clocks. Motherboard BIOS settings might also play a role—sharing your hardware details would be helpful, and clarifying how you reached the 4.9ghz overclock would be beneficial.

The 8700K fits into the silicon range similar to other chips, but achieving higher clocks requires either better cooling or adjusting the CPU temperature.
Motherboard BIOS configurations might also play a role, so it would be useful to note your hardware details and explain precisely how you reached the 4.9ghz overclock.

The 8700K fits into the silicon range similar to other chips you might have, but unless you improve cooling or fix the CPU, higher clocks won't be possible. BIOS settings on the motherboard can also play a role regarding your overclock adjustments—please share your hardware details for more guidance. I used an ASRock Z370 Extreme4, set the CPU ratio to x49 and the CPU voltage core voltage to auto. It runs stably, but the temperature fluctuates between 55°C and 70°C. Will every i7-8700k maintain a stable temperature?

If the system isn't undergoing stress tests using benchmarking tools, you'll notice temperature changes every second. Gaming doesn't qualify as a load test because system demand rises and falls frequently.
The only instances where temperatures don't change much are during full system load and complete idle periods.
