iCooler III Cooling Technology

iCooler III features a high performance dual slot cooler. Massive amount of cool air is drawn from the central cooler to cool down the internal fins directly. Heat from the 4770 GPU can rapidly transfer to internal fins that extend under the cooler. The optimized iCooler fan design allows air flow to pass in and out and removes heat effectively. With efficient central powerful cooling, the iCooler III offer excellent cooling and noise control performance for the system. The noise level is under 24dB, which is 20dB lower than reference cooler

Key Features

• Faster: Heat transfers rapidly out of GPU and reduces temperature instantly
• Cooler: Award-winning and performance leading iCooler technology
• Quieter: iCooler III excel in noise management. It's extremely quite and noise level is less than 24dB

Massive amount of air is drawn from the central cooler to cool down the fins underneath	Noise level is less than 24dB, much lower than the reference cooler (44dB)

 

Beat the GeForce 9800GT and 9600GT

" It's also faster than the GeForce 9800 GT, by a significant amount in some cases, and doesn't lose a single benchmark to it......It's also the fastest of all in Enemy Territory " - Benchmark by Hexus.net

" Even at 1680x1050, we see HIS' Radeon HD 4770 snag a definitive victory over the GeForce 9800 GT, to the tune of over 40%. " - Benchmark by Elite Bastards

Benchmark provided by AMD

" In Stalker DirectX10.1 environment, cards calibrate excellently as well. Two HIS Radeon HD4770 achieved about 20% better results than GTX285 and GTX275.......In STALKER game the profit over a single card 4770 is very high. Performance gain is almost 200%! We can see unquestionable advantage over single card construction as well from similar price range.  " - Review by Benchmark.pl

" Looking at the comparison between the 4770 and 9800 GT we see once again that the ATI card is a better performer " - Benchmark by Driver Heaven

Lower Power Comsumption due to the industry's cutting-edge 40nm process technology
