Noctua NF-A14 PWM Fan, SSO2 Bearing, 140mm, Brown

This 140mm cooling fan is engineered for both demanding radiator installations and standard case ventilation, maintaining a 25mm depth profile. It utilizes a 4-pin pulse-width modulation (PWM) interface, allowing the system to automatically regulate fan speed across a broad range, from a minimum of 0 RPM up to 1500 revolutions per minute (RPM). At its maximum rotational speed, the unit delivers a substantial airflow of 140.2 cubic meters per hour and generates a static pressure of 2.08 mmH₂O. This configuration facilitates effective temperature control across various restriction levels, including heatsinks and fine mesh dust filters.

Noise output registers at 24.6 dB(A) during peak 1500 RPM operation. An included Low-Noise Adaptor (LNA) cable can be utilized to reduce the maximum speed to 1200 RPM, decreasing the resulting sound output to 19.2 dB(A). The frame and impeller construction uses PBT GF30 polymer, providing stable physical characteristics under varying thermal conditions. Reliability is supported by the integrated SSO2 bearing technology, contributing to the fan's rated Mean Time To Failure (MTTF) of 150,000 hours of continuous use.
