With its upgraded cooler, the HIS Radeon HD 7750 maxed at 64 degrees under stress in FurMark, which is the same temperature reached by the Gigabyte GeForce GTX 460. The majority of low-end to mid-range graphics cards operated at around 60 degrees, so nothing there’s out of the ordinary here. On the other hand, AMD’s Radeon HD 7770 reference design got quite hot at 81 degrees. We should note that at this temperature, the graphics card fan didn’t make any more noise than the chassis fans. Additionally, the HD 7770 is one of the few products using a reference cooler in the above graph.
