Linux Mint 20 as well as Ubuntu 20.04 No Fan with RTX 2080 in SLI

Hi there,
I tried to install Linux Mint 20 today and as soon I start the live system, the fans on my GPU’s stop completely. I can start the live system and run it for about 10-15min before the GPU’s hit 85C and I have to switch off the system. I’ve also tried Ubuntu 20.04 and it’s the same.
On Mint, I’ve loaded the Nvidia driver 440.xx but nothing changed. I also tried to run the command nvidia-setting -a ‘[gpu:0]/GPUFanControlState=1’ -a ‘[fan:0]/GPUTargetFanSpeed=90’ but it didn’t work.

My current system is Windows 10 Pro and I don’t have any issues with the GPU’s there.

Thanks
