Fans and CPU running very high Windows 10 Build 1903

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.

    After disabling Cortana, I confirm that I have a noticeable decrease in the CPU usage and CPU works 5 °C cooler. However, it can still be better than what it is now. I don't believe that Cortana is so much inefficient in resource usage.

    TheSETJ, very interesting.  I always have Cortana disabled.  I never use it.  My temps run mid 50's when I have Power service enabled and mid 30's when I disable it.  I have not checked to see if enabling Cortana would have an effect on either temperature range.  I have 6 fans and am water-cooled.  I will leave the Power service disabled until Microsoft comes out with a fix.

    Agreed, Cortana was one of the bigger resource hogs - on my rig I ave a total of 5 others that are disabled which has improved the temps both on CPU, GPU, Memory and Power.  Like Richard I also am water cooled with dual 240 mm fans for the CPU. with 6 other 140 mm fans - unit I have in degrees F rather than Celsius and temps are running CPU about 85 average - GPU 77 F average Liquid 84 F average and power 87 F average - when gaming I am in the high 90's F to around 105 F.  I do have 2 programs that monitor temps, fans, mem, and power the NZXT Cam as well as the EVGA Precision XOC these programs work great

    Same issue here with me. But I noticed something. This is probably not the issue with many of you who replied to this thread, but I run a headless home automation server on win10. So when I configure it, I RDP to the PC.

    This build 1903 has also peaked my CPU (ran from ~8% to ~54% after the update). I tried all the suggestion in this thread to no avail.

    But I noticed that when I was RDP to the PC, the cpu ran ~15-20%. But when I logged out of the RDP session, the CPU went back up to +50% (I can tell because the automation software runs a WMI poll of CPU and MEM, which I trigger an email on if it exceeds 40%.)  

    Anyway, I added a monitor, keyboard, and mouse to watch the PC when not RDP'd in to see if I could catch a process spiking the CPU. I was thinking it was a maint task, or scan.

    But to my surprise with a monitor and keyboard/mouse attached, the PC runs back down ~8-10% again.

    Just to be sure, I removed the monitor keyboard and mouse again, rebooted, waited a few and it spiked again.

    I think I found my issue, Not sure this is the same use case as others, but thought I would mention it.

    Hey there - glad for the reply - I can see that you are prob one of the few that run the headless home auto server - I would suggest to take screenshots and compile a record to send to Microsoft - the issue with the temps is ongoing and for Me I have resolved them however it took a lot of time and effort to find the fixes for my systems and this should not be the case - hopefully MS will resolve this major issue soon.  I have sent everything I could to them but nothing other than they received it.  Glad you responded to this issue
