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 Oil surface tension and hydrodynamic pumping forces provided by grooves, no friction, extremely quiet 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.
