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.
Excerpt: AMD has wasted no time bringing its DirectX 11 GPU architecture to a more affordable, mainstream-class GPU in the HD 5770. HIS is one of the first manufacturers to bring the HD 5770 to market. At around $160, the card is priced similarly to existing Radeon HD 4870 cards. It’s the lowest-cost card in the roundup, and given the 180mm2 die size (that’s incredibly tiny for a GPU), prices are likely to eventually come down even further.
Pros: Affordable; DirectX 11 support; only one power connector needed.
Cons: Only a one year warranty; toolkit bundle from Newegg only
