Stable Speed Under Load
The closed-loop motor monitors and adjusts rotation to hold the target RPM even when airflow is restricted by dense radiators or fan grills. This prevents speed fluctuations and keeps cooling performance predictable.

A triple pack of 120mm PWM fans built for consistent airflow on radiators and heatsinks. Closed-loop motor control keeps speed stable under load.
The closed-loop motor monitors and adjusts rotation to hold the target RPM even when airflow is restricted by dense radiators or fan grills. This prevents speed fluctuations and keeps cooling performance predictable.
A revised frame minimizes air loss around the edges while nine optimized blades generate up to 2.41 mmH2O of static pressure. The design suits both liquid cooling radiators and high-density air coolers.
A low 5V starting voltage allows near-silent idle operation. The rifle bearing provides a rated lifespan of 80,000 hours, and maximum noise reaches 30.9 dB(A) at full speed.
The package contains three 120mm x 25mm black fans, each with a 4-pin PWM connector for motherboard speed control.
