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.
