Are you using any kind of fan control or thermal management software?
I have a Clevo PB51DDS and I’m using Obsidian Fan Control.
Win10 optimized with all rules, maximum performance power profile, everything.
I can reproduce glitches and dropouts after some time when I use the “silent” profile for fan control. I have to run the fans at some higher rpm, creating some more fan noise, especially during GP loading or background activities of Windows. No fan noise during normal performance.
