@rathod-sahaab I'm also using A5M, please let me know if you found any solution for the fans and thermal management for linux.

[arunn03]

I am too using the same model (Modern 15 A5M). Please support this model.

Hello, I am thinking about buying Modern 15 A5M (AMD 5500U). Can you please tell me if the fan control problem still exist? Thx.

[ng0177]

Same here. Appreciate the hard work! Please support :+1:

[kuznet1]

I did some research, you can control fans if set fan_mode to Advanced (0x8C). But you can't set fans speed less than 45%, only stop if set speed to zero. It seems like a common msi thing. Tried 155LEMS1.104 and 155LEMS1.106 EC firmware versions, same thing

[ng0177]

True. On an MSI desktop machine w/ NVIDIA, I had to flash VBIOS. Setting the speed to zero is no issue when e.g. Freon Gnome Shell Extension is used to monitor the temperatue.
