Hi,i have a question...my GTX260 Gigabyte runs in 52-57c in IDLE and 75-85 in LOAD when i play games like Battlefield 3 multiplayer and Assassins Creed Black Flag.
Those temps are well within safe ranges, 105C is the max for that gpu. It wouldn't hurt to put in a case fan to blow cold air onto it or maybe do some cable management (if applicable) to get the temps down.
The above poster is right and for my Radeon R5 M230, my Idle temp. is 50.C, 57-58.C during normal work and around 70 during gaming, coincidentally Battlefield 3 as well Just for reference. As a tip you might want to check out the dust in your fan or whatsoever, thats my maximum knowledge for computer already 😛
