Silent Fan Technology

Dual Silencio fans to increase the performance of heat dissipation.

Reduced Noise and Power Output

PWM fans put out signal impulses that cause clicking noises and deformations within the fan. But Cooler Master's exclusive Silent Driver IC slows down the signal rate, suppressing the PWM switching sound. This results in an ultra-quiet 11 dB and low power current that clocks in at 0.6w(12V, 0.05A), not only making it the quieter choice but also helping you save on your energy bill.

Quality and Reliability

The Loop Dynamic Bearing (LDB) is a rigid and abrasion resistant compound that reduces vibrations, noise, and increases life expectancy to 160,000 hours. The self-lubricating and IP6X dustproofing design protects the bearing and keeps it operating smoothly, ensuring a new system will likely be long obsolete by the time these fans expire.
