system fans cut to half speed after loading into windows

[Rodneyg87]

So here's the thing got on this morning all exited about the new nvidia driver, well after downloading that and finding for some reason freesync with my gtx 1080 ti will not engage I restarted my pc one last time to see if it would kick in. Well when I hit the sign in window all of a sudden my fans which I normally keep at 100% for maximum cooling kicked down to 50% speed then I put my password in and open up Asus AI suite to turn them back up. Once I hit the turbo button all of a sudden my system shuts down. Restart after having to cycle the power button on the power supply all is normal except the fans anyone have any ideas? And any time I try to kick the fans back up in windows the system shuts off go into bios turn the curves back up the work like normal till I hit sign in screen once again then back down cycle keeps repeating.

ok that's weird after writing this threat I thought to myself why not try uninstalling AI suite all of a sudden now my fans are staying at their normal 100% speeds without a system shut down. But that program has been on my system since I built it due to it being part of the chipset package for my motherboard.

There have been some Windows system updates recently.  Maybe the program isn't compatible with the latest update.
