Ultimate Cooling Weapon for ATI Radeon HD5970 As an extension of the acclaimed Accelero XTREME series, this 3-fan cooler is specially designed for the ATI Radeon HD 5970. The performance is exellent 40C cooler then the stock cooler running at only 0.5 Sone. Overclocking can be maximized to a new level, making the Accelero XTREME 5970 the most effective cooler for this high-end graphic card. Main features Unmateched cooling performance - 300 Watts 3 ultra quiet 92mm PWM fans with low noise impeller 8 heatpipes and 119 fins for efficient heat dissipation Patented fan holder eliminates the buzzing sounds RAM and voltage regular cooling Pre-applied ARCTIC MX-2 CrossFire compatible Excellent cooling performance Both models are equipped with three 92mm PWM fans running from 900 to 2,000 RPM, generating 81 CFM airflow for efficient heat dissipation from the core(s). The Accelero XTREME 5970 is designed with an 8-heatpipe and 119-fin architecture to achieve 300 watts cooling for the dual-GPU Radeon HD5970. A layer of the ARCTIC MX-2 thermal compound is also pre-applied on the base of Accelero XTREME 5970. The results are very promising– the GPU temperature of Radeon HD5970 is now 40°C lower than using the stock cooler. This enhances not only the overclocking performance, but also extends the service life of your valuable VGA card. Whisper quiet Using three fans does not mean the noise level will be high. The precise fan blade design improves the laminar airflow and helps reducing the noise level to a minimum - only 0.5 sone at full speed (2,000 rpm). The patented fan holder and PWM function helps the Accelero XTREME 5970 to reduce the noise further, creating a much quieter gaming environment.
