Unmatched Cooling Performance

The new Accelero comes with four heatpipes which are connected to 30 fins. These 30 fins are cooled by two 80mm PWM fans, which give the Accelero Twin Turbo airflow to 40CFM and up to 120 Watts of cooling capacity. Together with memory and voltage regulator cooling, this new VGA cooler gives enthusiasts a very promising result. With such phenomenal cooling performance, the Accelero TWIN TURBO also maximises the overclocking potential and extends the service life of your graphics card.

The Art of Silence

Low noise impeller and patented fan holder are installed in the two 80mm PWM fans.

With Force3D™ Radeonä HD4850 & HD4870 w/ Accelero Twin Turbo, gamers can watch the latest Blu-ray and HD-DVD videos in full 1080p HD without placing too much a burden on the CPU.
