How much temperature reading is shown when you are playing games and you are not??normally gpu heat when load is increased.most probably for gaming editing and other graphics oriented programs.your gpu is good and heating will not be a problem when temp readings are between 75-80 while playing games.if the idle temp is equal to the load temp,,let me know that??coz that must be of different reasons and depends on several factors like room setup,cabin placement,cabin type etc.so let me know what temp readings are shown when u r playing games and you r not.thankz
