Fan Size: 140mm
PWM stands for Pulse Width Modulation. The 4-Pin connector allows the mainboard to control the fan speed from 800-1500RPM.
Optimum airflow, air pressure & extremely silent performance
Innovative blade design focus air flow & optimum cooling efficiency
Reduce the vibrations efficiently & silent operation
Air-inlet with optimal aero-dynamical design reducing noisy air turbulences
HDB runs more smoothly with no friction, make it quietly & durability(MTBF300,000hrs)
Rubber fixed pins also reduces vibrations (fan run more quietly) and Tool-less makes it easy to mount, with no tools required
