With the previous drivers I was able to lower the fan speed of my GPU to 20%. Now I can only set it to 55% (the default speed after X is started) or higher. None of the following methods work:
Setting the fan speed in the nvidia-settings GUI. Any value I try below 55%, it just sets back to 55%.
nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUCurrentFanSpeed=20"
Attribute 'GPUFanControlState' (NightFury:0[gpu:0]) assigned value 1.
Attribute 'GPUCurrentFanSpeed' (NightFury:0[fan:0]) assigned value 20.
But the fan speed remains the same if I try to set it below 55% (I can hear it so and I can check it in the nvidia-settings GUI).
"nvclock -f -F 20" previously worked, but now I get a segmentation fault. I know nvclock isn't something officially supported, but I thought you should know anyway.
I want to mention that the GPU temperature is not an issue. Previously with 20% fan speed it would stay around 55C. Now it's at 47C.
I have attached the output from nvidia-bug-report.sh
