Description
The Noctua NF-A4x20 PWM case fan, in its beige and brown colour scheme, is designed for compact spaces thanks to its 4 cm diameter and 4-pin connector. This model offers a rotation range of 1200 to 5000 RPM, with a maximum airflow of 9.4 m³/h and a static pressure of up to 2.26 mmH2O. Its noise level stays between 12.2 dB with the LNA adapter and 14.9 dB at maximum speed, operating with a power consumption of only 0.6 W. PWM (pulse-width modulation) compatibility allows the speed to be adjusted according to system temperature, although it is not compatible with specific processors or sockets, as its use is limited to case cooling.
