Sigma Pro 140 PWM

Silent operation

Sigma Pro series are very silent thanks to modern HBS bearing (Hydraulic Bearing System)

Sigma Pro 140 PWM is a versatile fan made for 120 and 140 mm fan brackets thanks to special housing with mounting adapters. Using bigger fan for your CPU cooler or case (as long as there’s enough space) is a low cost method to make your performance better and lower the noise level.

PWM function allows most motherboards on a market to automatically adjust rotation speed in 500-1400 RPM range. Specialized motor allows rotor spin at 5 V and this feature makes Sigma Pro PWM compatible with fan controllers built-in SilentiumPC cases.
