Introducing the high quality quiet 12cm fan with patent pending FDB (Fluid Dynamic Bearing) technology. This "Fluid Dynamic Bearing" technology from SONY Corporation can provide a dramatic reduction in fan noise and prolong the life of your fan.


Equipped with Genuine S-FDB Bearing
This fan is equipped with genuine S-FDB (SONY Fluid Dynamic Bearing) made by SONY corporation.

Market Leading Low-Noise Level
S-FDB technology drastically eliminates the friction between the bearing and the shaft which makes this fan nearly inaudible to human ears. Additional suction magnet optimizes the magnetic force balance within the rotor to achieve absolute silence. To even further achieve the absolute silence, the fan is equipped with the Linear drive IC for reducing electromagnetic noise.

Outstanding Long Life of 150,00 Hours
Patent Pending "S-FDB" structure allows the fan to last up to 150,000 hours.

Anti-Shock Ability
Conventional ball bearing carries a point contacting structure for rotation. This gives a point supporting situations and dropping impact which can damage the ball bearing surface leading to irregular noise. The S-FDB carries a surface contact mechanism for improved anti-shock structure, which is 5 times stronger than the conventional ball bearing.
