Hi there, have tried to monitor the temps of your GPU? there is a utility called GetThermal , search the forum for it. my temps are like this after putting arctic silver 5 on my GPU : idle 62 playing games 77 or st like that.
So if you have any high temps contact sager w\o telling them about the getthermal thing because it will void you warrantly, and tell them about the problem. bye
