Just got this problem recently. My i7 7700k got 96°C - 100°C static using AIO Id-Cooling Icekimo 120. Nothing overclock. Already trying change thermal paste, checking pump if tight or not but the problem still remain. Here I provide image from cpu-z, HWmonitor and Intel Extreme Tuning Utility https://imgur.com/a/3MD8WKA
p/s: My main suspect here is AIO. But need confirmation from expert before buy new cooler.
