Pure Wings 3 120Mm Pwm

The be quiet! PURE WINGS 3 120mm PWM (BL105) is a case fan for moving air through a PC. Its 120 × 25 × 120 mm frame is black and connects through a 4-pin PWM plug, allowing speed control through a compatible fan header.

The fan uses a rifle bearing and 4-pole motor. The manufacturer lists an operating lifespan of 80,000 hours at 25°C. Four mounting screws are listed as accessories.
