REVIEW: Pro-Clockers.com..........."The S-Flex line of large PC cooling fans is awesome for anyone that is
looking for quietness. These units was absolutely silent, we had to place our ear right up on the motor to hear
anything. We are really impressed by today’s offering from Scythe. "
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 Life Expectancy
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.
S-FLEX™ is SONY corp patented bearing technology.
