Technical Details
PWM-FUNCTION
PWM stands for Pulse Width Modulation. The 4-Pin connector allows the mainboard to control the fan speed from 800-1500RPM.
HIGH-VORTEX-AIRFLOW WITH TURBINE BLADE & FRAME PATENTED DESIGN
Optimum airflow, air pressure & extremely silent performance
DIVERSION GROOVE BLADE DESIGN
Innovative blade design focus air flow & optimum cooling efficiency (Patent)
ANTI-VIBRATION PAD DESIGN
Reduce the vibrations efficiently & silent operation
AERO-DYNAMICAL DESIGN
Air-inlet with optimal aero-dynamical design reducing noisy air turbulences
HYDRO-DYNAMIC-BEARING TECHNOLOGY
HDB runs more smoothly with no friction, make it quietly & durability(MTBF300,000hrs)
TOOL-LESS FIXED PINS
Rubber fixed pins also reduces vibrations (fan run more quietly) and Tool-less makes it easy to mount, with no tools required
PWM-Function
PWM stands for Pulse Width Modulation. The 4-Pin connector allows the mainboard to control the fan speed from 800-1500RPM. Fan speed is controlled by the PWM-signal, which delivers a value between 0-100%, the operating voltage remains a constant 12V.

HYDRO-DYNAMIC-BEARING TECHNOLOGY
We defined HDB to Hydro Dynamic Bearing. An oil seal design that has a higher reliability and advantage than conventional fan motor design.
1. High revolution precision, low vibration noise
2. Fluid seal design provide extremely long life span
3. Surface tension effect, runs more smoothly with no friction, extremely quiet
Fluid seal design is achieved through the use of oil surface tension and hydrodynamic pumping forces provided by grooves. Bend area is centralized oil and prevented oil leakage out of motor (oil leakage is main problem of sleeve bearing, short life time) . Friction between shaft and HDB will be down due to herringbone structure reaction(friction between the metal is disadvantage of ball bearing, noise & waste heat problem). So HDB conquer sleeve & ball bearing disadvantage to become more reliable & quiet technology for Top-notch fan. Such design concept is successful and applicative on HDD, and we can see a reliability application in it.
