Description
The NF-A12x25r is a round-frame version of Noctua’s award-winning flagship model 120mm NF-A12x25 fan. Its round shape makes it ideal for use on low-height dual-tower CPU coolers like the NH-D12L as well as other space-restricted applications that cannot accommodate square-frame 120mm fans. Just like the square NF-A12x25, the round NF-A12x25r uses a record-tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox® liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision. Sharing the same state-of-the-art impeller design with Flow Acceleration Channels, the NF-A12x25r achieves the same class-leading quiet cooling performance as its square-frame sibling.
It also supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 2000 to 1700rpm. Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the NF-A12x25r is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for all 120mm applications that require a round frame.
