Scythe S-FLEX 120mm Fan 800 RPM SFF21D

The Scythe S-FLEX fans are equipped with genuine S-FDB (SONY Fluid Dynamic Bearing) manufactured by SONY corporation. 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 optimises the magnetic force balance within the rotor to achieve absolute silence. To make this fan even quieter, the fan is equipped with the Linear drive IC for reducing electromagnetic noise.

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 fives times stronger than a conventional ball bearing. Available in three different fan speeds, there is a solution for everybody.
