The Witcher 3 is creating a lot of folk posting your exact question.
Also, FORGET measuring temps. Do the work like this link suggests.
I've run into gamers that resist doing the work. They tend to suffer longer than most.
As some of you may know I have already been on this forum once asking for help because my computer was "overheating". I have come to find out that my temperatures are fine, but I still have frame throttles that will make my game drop from 60fps to anywhere from 5-35 fps. What could be the cause of this? My computer is very newly built with no errors on the hardware ( at least, I don't believe so). Here are some additional pictures of my fps, my GPU temp while gaming at medium settings, and my specifications: http://i.imgur.com/KO8KNUG.png http://i.imgur.com/EljO8ri.png and http://i.imgur.com/ngEKMov.png
