i have got all current drivers on everything as i done a fresh install 2 days ago. i successfully played for an hour earlier with no crash with side panel off. My temps were at least 5 degrees lower. Going to keep trying over the course of the next few days and if it is heating then i will get new case and fans.
Nice, hope you manage to enjoy it, or else , yes consider new fans.
be sure if its overheating though, as a fresh install of everything cant lower your temps !
