I running an nvidia 770 and recently the fans have been ramping up/down. Just idling at the desktop the gpu temp is showing 33degC and fan speed is variable, between 25 and 30% nothing changes but every 10-15seconds it ramps the fans up to 100% for a second and then drops back down.
The drivers are version 415.18. I have enabled 'coolbits' '4' and in the nvidia-settings panel changing the fan control to manual has no effect, the fan speed continues to be automatic and variable.
Any ideas on what might be causing this?
Thanks.

Hi,
i have a similar question. I'm running an RTX2070 Nvidia Card. This gpu has 2 fans. When i boot up, i got 1 fan running at normal speed the other fan boosts up and down. nvidia settings show stable values for fan1 at 1500 rpm 41 % speed. However the speed values from the second fan go vom 2000 rpm to 18000 rpm up and down. Setting coolbits to 4 didnt have any effect for getting both fans at a stable rpm rate.
Nvidia driver version would be 455.28.
It seems as if the sensor didnt get the correct rpm signal? Is this a hardware related thing or are there any other reasons with caused this behaviour?
Thanks in advance
