On a laptop that old it might be worth opening it up to blow all the dust out with a compressor or air duster. I’ve often found that to work wonders on old MacBook Pros.

The other issue is that unless the battery has been replaced relatively recently its charging efficiency may not be that great and the high load being placed on it might be causing it to get hotter than it would have done when new.

Hold my beer. I'm going to run Qwen on this 3rd-generation iPod... somewhere my partner can see

Could be in need of a thermal paste refresh etc.?
