The Enermax Cluster 80mm x 25mm LED PWM Fan features the new "Twister" bearing technology that provides the fan with a lifespan that is double that of a standard dual ball bearing fan. The Enermax Cluster is incredibly quiet for it's size, making only 19 dB at full speed and yet it manages to move a substantial 32+ CFM!
The fan uses a unique BATWING blade design to maximize the air flow output of the fan. The HALO fan frame is carved out to reduce cavitation from the fan blades and thus reducing the noise levels produced by the fan. The fan can be cleaned easily with the detachable fan blades - dust build-up not only looks ugly but it also increases the weight of the blades, putting more strain on the motor.
The Enermax Cluster is equipped with LED lights that illuminate during operation, making the fan more than just a cooling device but an aesthetic accent for your computer case as well.
