Pure Wings 3 120mm PWM High Speed

The Pure Wings 3 BL106 is a single 120mm case fan built for desktop PCs that need strong airflow. Its 4-pin PWM connector allows the motherboard to control speed precisely from idle to full load. The rifle bearing is rated for 80000 hours of operation.

Closed-loop motor holds target RPM

A closed-loop motor monitors actual speed and corrects it when resistance from a radiator or grille slows the blades. This keeps the fan at the requested RPM instead of drifting lower under back-pressure. The frame outlet is shaped to reduce air leaks, which helps maintain static pressure through dense fin stacks.

55-60 CFM at 2100 RPM with 30.9 dBA

At maximum speed the fan moves between 55 and 60 CFM while producing 30.9 dBA of noise. The low minimum RPM lets the system run very quietly during light workloads. Builders who need higher static pressure or greater airflow than this range provides will need a different solution.

Questions about this item

Which Pure Wings 3 120mm version should I choose if I need maximum airflow for a radiator?

The BL106 high-speed model delivers 55-60 CFM at 2100 RPM, and its frame outlet is designed to minimise air leaks specifically for radiator performance.

What does the 30.9 dBA noise rating mean when the fan is running inside my case?

At the maximum 2100 RPM the fan produces 30.9 dBA; PWM control lets you run it at lower speeds for quieter operation during lighter loads.

How does the 4-pin PWM connector affect speed control in practice?

The 4-pin PWM header allows the motherboard to vary the fan speed precisely from a low minimum up to the 2100 RPM maximum based on temperature curves.
