Noctua NF‑A12x25r PWM 120mm Round‑Frame Quiet Fan – 2000RPM

Noctua NF‑A12x25r PWM – 120mm Round‑Frame 

The Noctua NF‑A12x25r PWM is a premium round‑frame 120mm cooling fan engineered for applications where a standard square‑frame fan cannot fit. Designed as a variant of Noctua’s award‑winning NF‑A12x25, it delivers exceptional quiet cooling performance thanks to its advanced aerodynamic blade design, ultra‑tight 0.5mm tip clearance, and Sterrox liquid‑crystal polymer construction.

With PWM control and speeds up to 2000 RPM, the NF‑A12x25r provides excellent airflow and static pressure while maintaining low noise levels. It includes a Low‑Noise Adaptor to reduce maximum speed to 1700 RPM for even quieter operation. Ideal for space‑restricted CPU coolers like the NH‑D12L and specialised mounting scenarios requiring 93×83mm hole spacing.
