With Computex looming upon us, Noctua shared their excitement with us as they announced their new generation of fans – the NF-A12x25 which is the first of Noctua’s fan to use their Sterrox LCP material and integrated with their latest innovations and magnificent engineering to achieve unprecedented silence and performance. There’s also a new NF-P12 series of fans is now reissued to the affordable Redux lineup too. Last but definitely not the least, Noctua announces the NA-SFMA1 adaptor where it allows 120mm fans to be mounted on 140mm holes.
“The NF-A12x25 is our most advanced fan today. We’ve spent more than 4.5 years developing it and it’s been easily the most thorny, intricate development project we’ve completed so far. In order to achieve our goal of surpassing our renowned NF-F12 and NF-S12A, we went for a completely different approach and had to use a tip clearance of only 0.5mm, which poses various new difficulties in manufacturing.”
– Lars Strömbäck, Noctua CTO
Sounds familiar? That’s because they were talking about it during last year’s Computex. The new NF-A12x25 follows the approach of Noctua’s A-series in being a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators. In practice, the NF-A12x25 not only outperforms the renowned NF-F12 on 120mm based watercooling radiators, but combined with the new, optional NA-SFMA1 adaptor frames, it also offers better efficiency than many 140mm fans on 140mm based systems, according to Noctua.
One of the cornerstones of the NF-A12x25’s next-generation performance is its record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame. Manufacturing a fan with such a small tip clearance is extremely delicate and was only made possible by Noctua’s new Sterrox liquid-crystal polymer (LCP) material, which features extreme tensile strength, an exceptionally low thermal expansion coefficient and excellent dimensional stability.
“We have never put so much research and effort into a single fan so far, both on the level of fine-tuning the aerodynamic construction and on the level of materials and manufacturing. Many challenges had to be overcome, but now we’re proud with the end result and confident that the NF-A12x25 will become a new benchmark for premium-quality quiet 120mm fans.”
– Roland Mossig (Noctua CEO)
The NF-A12x25 will be available in a 4-pin PWM version for automatic speed control, 3-pin FLX version with Low-Noise Adaptors for three different speed settings as well as a near-silent 3-pin ULN (Ultra-Low-Noise) version. As the NF-A12x25 becomes the new flagship model in Noctua’s 120mm range, the classic NF-P12 moves to the streamlined, more affordable redux line. It will henceforth be available in 1700 and 1300rpm 4-pin PWM versions as well as 1300 and 900rpm 3-pin versions.
