Scythe 120mm S-Flex SFF21E 1200RPM 20.1dBA 49CFM Sony Dynamic Fluid Dynamic Bearing Ultra-Quiet PC Case Cooling Fan: SFF21E (120x120x25mm, 3/4 Pin, Retail)

Features:

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 the absolute silence. To further achieve the absolute silence, the fan is equipped with the Linear drive IC for reducing electromagnetic noise.

Outstanding Long Life of 15000 Hours
Patent Pending "S-FDB" structure allows the fan to last up to 150000 hours.

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