Hi !
 
Since updating to NVIDIA drivers higher than version 560.70, I have been facing the same issue: once the update is done, the GPU fans stop working. I can no longer get any fan speed information in the X1 software. When the card is stressed in a game and reaches the maximum temperature, it goes into safety mode, resulting in a black screen! If I downgrade back to version 560.70, everything returns to normal.

Was X1 is OFF, when you update your Nvidia drivers?

Hello! Good question.
 
I had to perform the Nvidia driver downgrade about ten times (using DDU, notably). Whether it was with or without X1 running, I couldn’t say. I’ll run another test in the next few days. I doubt that X1 is related to the problem encountered. When I use the control panel integrated with Nvidia, the fan speed information is just as inaccurate.


Thank you for your help.

Known issues
---> if you update/ install Nvidia drivers with Any GPU, OC software running, make sure "start with PC" is unchecked & then turnOC software  off before changing drivers
 
--->>> Make sure Fast Boot is off in MB BIOS settings
 
---->>> turn Windows Fast Start Off, or at the very least "Clear the Widows last good start file"  (hold shift key down, select shut down, keeping shift down till all power is Off to PC)
