When playing any windows game the PC heats up to 90 no matter what it is doing. This doesnt happen a lot on other type of games like Wii or GC games (dolphin flatpak). Is there any solution or do I really need to find out how to disable TurboBoost?

FIXED: I dropped ChromeOS and switched to Fedora. It doesn't heat crazy anymore.

If you want an explanation of why this happens with most games:

ChromeOS has LXC Containers support natively, and they use them. Inside a virtual machine. Yes. Host > VM > LXC > Your game.
