Thermal problem with Asus laptop running Linux

[Lt Australia]

I have been running CoH on my desktop using Linux/Lutris nicely with both Tequila and HC launcher. However I got frustrated with Win10 being slow on my relatively new AMD laptop (A12 with discreet Rawdon graphics) so installed Linux to play the game when staying at Mum's place. 

 

The game installs and runs, but shuts the computer down after a short period of play. Not a reboot, it looks like an automatic shutdown and my guess it is thermal shutdown. 

 

I am running the standard amdgpu driver from Ubuntu (20.10 x64) and I don't want to install the AMD pro driver, in part because AMD uses 20.10 for its own version release, which is slightly confusing. 

 

Any ideas to help reduce the heat as it is only CoH that causes it as I am running Gnome Boxes with Win10 guest so I know it is not system load 🤷‍♀️

Gnome Boxes is a big clue.  Are you running the game in Virtualization?

 

If that is the case, I'd try for Wine over QEMU personally.  Virtualized video cards are going to come up fairly short compared to Wine or DirectX.
