Yellow posted... Oh hi.
It isn't recommended to re-use thermal paste as it can dry out and crack, or create gaps of air. That probably goes double for the stuff that comes pre-applied. If you have some laying around, I'd clean it off with some alcohol and a swab and re-apply, it's pretty cheap. If you don't have any laying around, I'd put it back together, order some off the internet, and when it gets in the mail I'd re-apply it.
It won't hurt your computer if it thermally throttles. It will bring down the clock speed to protect itself if it has to.
Thanks, bro. Alcohol wont negatively affect anything?
