Noctua NF-A14x25r G2 PWM Sx2-PP chromax.black Case Fan 140 mm 2-pack Black

The Noctua NF-A14x25r G2 PWM Sx2-PP is a set of two 140mm fans designed for high-performance cooling applications. Their specifications are suited for use on liquid cooling radiators or large CPU air coolers where both airflow and static pressure are important factors. This "Sx2-PP" kit is specifically engineered for push-pull configurations, with a design intended to reduce harmonic noise that can occur when two fans operate in close proximity. The fan construction utilizes a combination of rigid materials, including liquid crystal polymer, to maintain stability at higher rotational speeds.

This second-generation ("G2") model incorporates specific aerodynamic features to balance airflow, pressure, and acoustics. A 4-pin PWM connector allows for automatic speed control via the motherboard, enabling the fans to operate at low RPMs for quiet idling and ramp up under load. The chromax.black edition provides an all-black aesthetic, which extends from the fan frame and blades to the included anti-vibration mounts and cabling. The package includes a PWM splitter cable and two 30 cm extension cables to facilitate installation and cable management.
