Arctic Cooling ATI Silencer 5 (Rev. 2)

Arctic Cooling ATI Silencer 5 (Rev. 2) ... the noise generated from the motor. A large fan and optimized fanblades offer a minimum noise level at a high airflow. Highest fin surface area and a 3.5 mm thick copper base achieve best cooling performance at its noise level. The ARCTIC Ceramic Bearing (alloy bearing and Ceramic shaft) provides fans with an outstanding service life.

The DHES draws cool air from inside the case and exhausts warm air outwards. This prevents the fan from recycling warm air to cool the GPU, which increases cooling performance. Further the DHES lowers the air temperature inside the case, because the heat of the GPU will be carried out directly.
