I upgraded to windows 10 version 1903 a few weeks ago. Shortly afterwards I noticed that my fans were running extremely fast and my CPU temps per core were running in the mid 50s C at system idle. Previously they were running in the mid to high 30s C.
Task Manager shows my CPU usage at 100%. I get things back to normal if I disable the Power service, but as soon as I enable it again, my fans begin to race and the temps go up. My system uses an ASRock motherboard with an Intel i7-8700k and an 8500 watt
power supply. I use the Balanced power setting profile. Diagnostics for Power doesn't pick up anything and I can't find anything with Google for anyone with a similar problem. I had a similar issue a couple of years back, but it was caused by me using the
High Performance power profile. Once I changed to the Balanced profile the problem disappeared. This time, the problem is occurring with the Balanced power setting. Any suggestions on how to resolve this would be appreciated.
