That growling/grinding I kept hearing? It was the right cooling fan. I noticed that when checking the fan speed, the right one was considerably slower than the left one, when the noise was going on (left: around 3000rpm, right: 900rpm). Mr. Giantpaper thought that the fan motor was dying, but just in case it wasn’t, he decided to apply some machine oil just in case.
It worked. đŽ I guess it took a while for the oil to lubricate the entire thing, because after turning it on after putting it back together, we heard a constant low hum from the right fan (sounded like r-r-r-r-r-r, like it kept hitting something). It went away after about an hour. Now I can’t hear the fans period. :O The laptop also stays a bit cooler now. It’s still a little warm, but not cook-eggs-with-this hot like it used to be.
