It's highly unlikely that you have damaged your 1055T.
If you did, it probably wouldn't even allow you to post, let alone boot into Windows.
We all learned some new info in how to read AMD CPU temps here:
If you reached 90C on any core temp, the 1055T would have gone into thermal shutdown.
AMD states a max. operating "core" temp of 62c with it's Phenom II CPU's.
As you can see, this threshold (62c) leaves a huge margin of safety.
Take your case side panel off and then monitor your CPU temp.
If you see improvement with it off, then you need to improve your case airflow.
