Noctua NF-A14x25r G2 PWM

Quiet 14 cm premium fan. Fan dimensions: 140 mm. Connection: 4-pin (PWM). Noise level: 24.8 dBA. Lighting: No. Minimum fan speed: 1250 rpm, maximum fan speed: 1500 rpm. The NF-A14 x 25r G2 is Noctua's flagship next-generation model in the 140 mm category with a round frame, developed based on the groundbreaking NF-A12 x 25 and its technological innovations. Thanks to its Sterrox LCP-made Progressive Bend Impeller with winglets, flow acceleration channels, and centrifugal turbulator hub, as well as a fan gap of only 0.7 mm, the NF-A14 x 25r G2 offers an even better combination of performance and quiet operation compared to its predecessor. The PWM connection allows for speed control via pulse width modulation using a PWM-capable motherboard. This dynamically adjusts the fan speed to the operating conditions, minimizing unnecessary noise generation.
