Product information

Description

The SilentiumPC Sigma Pro 140 PWM is a 140 mm case fan designed to improve cooling performance with low noise. Precisely engineered blades increase airflow while the HBS bearing provides smooth, reliable operation. The fan supports PWM control and runs between 500 and 1400 RPM, offering a balance between airflow and acoustic performance. Its dual 120/140 mm mounting design and included adapters allow mounting in either 120 mm or 140 mm locations, making it suitable for case installations and many CPU cooler upgrades when space permits.

Advantages

Quiet operation across the speed range with noise levels from 8 to 22 dB, PWM support for automatic speed regulation, optimized blade geometry for improved airflow (maximum 78.6 CFM), and a durable HBS bearing for extended reliable service. The dual mounting frame increases compatibility with different fan slots.

Suitable for

Case ventilation to improve overall airflow
Replacement or upgrade of existing 120 mm or 140 mm fans
CPU cooler fan upgrade where physical clearance allows
Liquid-cooling radiator installations compatible with 120/140 mm mounting

How to use

Install the Sigma Pro 140 PWM into a compatible 120 mm or 140 mm mounting location using the included adapters if needed. Connect the fan's PWM cable to a motherboard fan header that supports PWM control to allow automatic speed regulation between 500 and 1400 RPM. Ensure the fan orientation matches the desired airflow direction and that there is sufficient clearance if used as a CPU cooler fan upgrade.

Usage recommendations

For lowest noise, configure the motherboard fan curve to keep typical speeds toward the lower end of the 500–1400 RPM range and verify sufficient case airflow. Check clearance before replacing CPU cooler fans to ensure proper fit.
