You can pick up a cooling fan for a couple bucks...they actually work pretty well. This is a fancy one - but you can buy them anywhere cheap and they do work!
@FairyGirlGemma I've had the same one that's outlasted 3 laptops....and if anyone ever asks "did you get into some kind of computer nerd talk with FG Gemma"...I'll deny it! :) Have a great weekend!
@luctoretemergo In my experience (but I suppose it varies from laptop to laptop) those things do little in terms of lowering the internal temperature. Sure the bottom feels cooler at touch but in general if you have overheating issues (like abrupt shutdowns, or in modern machines, performance loss) those usually don't help much.
On the other hand, as hilarious as it may sound, with my current laptop all I needed to fix the overheating issues was a simple 0.70€ eraser cut in four pieces
