With the default Windows Balanced profile, this is what I got during a Cinebench R23 run, with a final score of 13700. Hitting 90 degrees Celsius is not ideal for sure.
Yep. 90c is throttle temp. You might want to check cooler mounting or your thermal paste application.
Also, as @tabascosauz mentioned, make sure you clear CMOS completely.
