93 is pretty darn hot. Definitely not temperatures you want for a card to last long.

1. Make sure your case has open air around it. Not in shelf where it can’t breathe and get cool air.

2. Make sure your case has good airflow as well. Neutral pressure is bad. I’ll link a video to explain the best way to have nice airflow in a case.

Make sure the GPU fans are spinning as well. Trial and error my friend.
