Ubuntu – Fans always ON and overheating on DELL XPS 15 9570 with NVIDIA GPU enabled


I have Ubuntu 19.04 on my DELL XPS 15 9570, with the 5.0.0-15-generic kernel version. This laptop has a NVIDIA GeForce GTX 1050 Ti GPU and all the time the fans are on around 3200/3700 RPM.

If I switch on Intel (Power saving mode) with PRIME Profiles of NVIDIA X Server Settings, the problem disappears and the fans turn around 0/2500 RPM.

How can I solve this problem? I don't want to bypass my NVIDIA GPU.

Thank you.
