Conclusion: Radeon GPUs have always been pretty hot (temperature-wise). I remember two years ago, when AMD/ATI released their Radeon HD 4850 ... Boy! the temperature produced by the graphics card was blisteringly hot, easily reaching 60-80 degrees. Luckily, their Radeon HD 5770 GPUs ain't as hot as its predecessor. Still, HIS made sure that their Radeon HD 5770 are properly cooled by their IceQ5 cooler.
