i7-8700k overheat + throttle on High Sierra while fine on Win 10

[truemetal]

I've got i7-8700k running on Asus Z370-F Gaming and cooled by ARCTIC Liquid Freezer 240, and I'm having problems with this setup on High Sierra.

While on Windows 10, it runs 4.3 Ghz and doesn't really go above 82 C, on High Sierra it can throttle and go up to 87-88 C.

Any ideas?
Thanks

Anybody have i7-8700k overclocked running successfully on High Sierra?

Im kind of having the same issue, I have a 4790K and get's overheated on high sierra 10.13.6, don't know what to do. Replaced the thermal paste, on my case I had too much thermal paste. I clean it up and add less thermal, now I get better results, but still going 86c, I have an Cooler master Evo 212, no overcloking, just XMP profile 1 activated.
