Windows 10: Unstable fan speed after 1803 update

    Unstable fan speed after 1803 update

    I updated to 1803 and everything looked fine except one of the fans is cycling up and down about every 2 seconds. I think it is the GPU fan but can't be sure unless I open the case. Quite noisy and annoying.
    Interestingly, if I put the computer to sleep mode and then return to normal mode then the fan is running quietly, but reverts the strange behavior after a restart.
    I have reverted to 1709 and everything is back to normal with the fan, but I have Win Home and I cannot stop the update. My computer shows that it is now downloading 1803 again !

    Any suggestions would be appreciated.

    Same here (CPU fan) with previous Insider builds. To stop 1803 from showing in WU, try the cmd line below. Run Disk Cleanup first.

    Powershell admin:
    reg add "HKLM\Software\Microsoft\WindowsUpdate\UX\Settings" /v "HideMCTLink"  /t REG_DWORD /d "1" /f

    You could use HW Monitor and watch your fan speed rpm's

    I used HW Monitor and it was showing GPU temp going from 0C to 50C, and fan going from 40% to 100% every couple of seconds.
    The GPU is (on board) AMD Radeon HD7650A and it is causing other problems like very slow computer operations.
    I was unable to find a driver that works properly so I have disabled it in device manager, and now fan is quiet and computer is responding very fast.

    Actually, I might be imagining things. But I am noticing my CPU fan is running erratically. I have the PM set to balance. I have a custom desktop. Specs are Asus Sabertooth Z170s, i5 6600K 4.2 ghz using a Coolmaster EVO cooler. 16 gigs DDR4-3000 (2 x 8 gig sticks), Gigabyte GTX 1080 G1. I am also using HW Monitor.
