I don't know what to do. It gets super hot and uncomfortable to type. I already can't use it on my lap because I would literally burn my thighs. It also gets super loud (fan) if I try to add a game to the mix and everything starts stuttering till I just shut it down.
Looks like you can pull the bottom panel and the fan and clean it that way. Here’s a decent guide:

Thanks!
Lmk if you hit a snag. Like I said make sure you disconnect the battery as soon as you can. Poking around in computers that can still turn on is bad news.
