Basically I can't play OW anymore, or any moderately demanding game. My fan goes crazy and my GPU gets to about 90C. It's a GTX660. It used to not be this bad.
My first idea would be to dust really well, because I have a ridiculously fluffy dog, but I'm not sure what I can take off and what I can't. I'm not sure what to do or where to post this. I tried to dust a little but I couldn't get anything notable.
EDIT:
I was to clean and change the thermal paste. Now it maxed at 64C.
