I use a Gigabyte GTX 1660 S for deep learning of neural networks under Ubuntu 18.04.
When I boot the PC, fans are idle --> OK
Under heavy gpu load, fans turn on to full blow --> OK
When I come back to gpu idle (temp back to 25 degres), fans remain at full blow --> KO
When I reboot the PC, fans are back to idle --> OK
nvidia-smi reports correct temperature, but fans are always at 0% (idle or full blow)
What is the procedure for automatic control of the GTX 1660 s fans with temperature under ubuntu 18.04?
Are the two fans controllable separately?
Thanks in advance. Regards.
