- Model: NF-A12x25r PWM
NF-A12x25r PWM
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.
