[Rishi Sharda (rishica2022)]

BIOS updated but fan still running high

[AaronMa (mapengyu)]

nvidia gpu is too hot, if GPU usage is low and it should be not that hot.
You can try NVIDIA runtime D3 too.

[Rishi Sharda (rishica2022)]

how do I enable this?

[Rishi Sharda (rishica2022)]

Please advise - GPU usage is minimal and fan still running high.

@rishi,

 Could you try 'sudo prime-select on-demand'? Thanks!
