Not the greatest guide. 2 and 3 shouldn’t be causing overheating unless you are running a potato. I don’t know the impact of 4, but I can’t imagine that its much on modern PCs. 1 and 5 are the only real advice. Blocked vents and dust are the other two good points, everything else seems questionable. Tab overload isn’t a problem anymore, both Chrome and Firefox manage and deactivate tabs you haven’t recently used.

Heroic Launcher on Linux lets you install Epic games and add them to Steam to launch. You don’t get any Steam features, you can just launch the game from Steam. This works both in desktop and steam deck.
