Cooler Master Silencio FP 120 3PIN (R4-SFNL-12FK-R1)

The Loop Dynamic Bearing (LDB) is a rigid and abrasion resistant compound that reduces vibrations, noise, and increases life expectancy to 160,000 hours.

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.

Total control of fan speed
A first in the industry, Cooler Master's exclusive High Precision Driver gives you 200x more precise control over the speed of your fan versus conventional fans. A perfect fit for those who use fan controllers, the Silencio FP offers you precise control of your fans RPM within �0.05%. Be in total command of your fan speed and cooling options.

Protect your fan and generate more air pressure
To help protect the blades and motor against fan jams, Smart Fan Engine technology stops power to the fan and features an auto-resume function after any blade obstructions are cleared. The unique blade design helps the fan generate 25% more air pressure
compared to conventional designs.
