Noctua introduces new A-series fans and accessories

Noctua expanded its A-series of premium-quality quiet cooling fans with new 200mm, 120mm and 40mm models. Thanks to the series’ signature features such as Flow Acceleration Channels and AAO (Advanced Acoustic Optimisation) frames, the new NF-A20, NF-A12x15 and NF-A4x20 provide performance and quietness of operation. 

All models come with Noctua’s trusted SSO2 bearings and a full 6-year manufacturer’s warranty. In addition to the new fans, Noctua introduced the new NA-FC1 fan controller, NA-SAV3 and NA-SAV4 anti-vibration mounts and NA-SAC5 S-ATA power adaptor cable.

“Customers have been asking us for 20cm and slim 12cm fans for years, but meeting the quality standard users have come to expect from Noctua fans in these form factors has proven very challenging, so it took us quite some time to make sure that these fans live up to our name“, explains Roland Mossig (Noctua CEO). “The NF-A4x20 has been conceived following requests by our industrial clients who are looking for a 40mm fan that provides superior performance in pressure-demanding applications as compared to the existing NF-A4x10.”

With the 20cm NF-A20, Noctua’s biggest fan yet, the key challenge was that the mass of the impeller is about four times greater than that of 12 or 14cm fans and thus creates a significantly higher load on the bearing. In the end, the difficulties were overcome by increasing the diameter of the axis and the bearing from 3mm to 4mm in order to distribute the load over a larger bearing surface, as well as by using a new fibreglass reinforced polypropylene (PP) material, which reduces the mass of the impeller by 26% as compared to Noctua’s standard fibreglass reinforced PBT material.

For the 12cm NF-A12x15, a steel-reinforced motor hub and brass axle mount are being used in order to assure the required stability despite the fan’s 15mm thin profile. Both the NF-A20 and the NF-A12x15 will come in 4-pin PWM versions for automatic speed control and 3-pin FLX versions that include Low-Noise and Ultra-Low-Noise adaptors, which give full flexibility in configuring the fan for maximum cooling capacity or near-silent acoustics.

The NF-A4x20 complements Noctua’s popular NF-A4x10 models: With 20 rather than 10mm thickness, the NF-A4x20 is better suited for applications that require higher pressure performance such as in servers or tightly packed enclosures. The NF-A4x20 will come in 12V 4-pin PWM and 12V 3-pin FLX versions for PC use and other 12V applications as well as in dedicated 5V and 5V PWM versions, which are ideal replacement fans for 5V-based switches, routers, DVRs or other devices.

All of the new fans share the A-series’ renowned quiet cooling performance as well as signature features such as Flow Acceleration Channels, Advanced Acoustic Optimisation (AAO) frames or SSO2 bearings. Like all A-series fans, the new NF-A20, NF-A12x15 and NF-A4x20 have an MTTF rating of more than 150,000 hours and come with a full 6-year manufacturer’s warranty.

In addition to the new quiet cooling fans, Noctua expanded its range of fan accessories: The new NA-FC1 is a compact, highly flexible controller for 4-pin PWM fans that can both work on its own for manual speed reduction and also work in tandem with the automatic motherboard fan control. By adjusting the NA-FC1’s speed control dial, users can either manually set a PWM duty cycle from 0 to 100% or reduce the PWM duty cycle supplied by PC motherboards in order to have the fans running slower than the automatic motherboard fan control would allow. Thanks to the supplied 3-way split cable and power supply adaptor, up to 3 fans can be controlled simultaneously.

The new NA-SAV3 and NA-SAV4 silicone anti-vibration mounts have five defined, numbered pawls that allow them to work perfectly with both standard open corner fans and 10, 14, 15, 20 or 25mm thick fans with closed corners. This makes the new mounts ideal for slim fans such as the new NF-A12x15 where other anti-vibration mounts may not fit properly. While the NA-SAV feature a double-side design that makes them much easier to work with in space-restricted environments or placements where the fan’s mounting holes are difficult to reach, the NA-AV4 have a flat case-side end that is flush with the case panel and thus provides for a clean exterior look.

The new NA-SAC5 is a fully sleeved S-ATA to 4-pin power adaptor cable. It is compatible with both 3-pin and 4-pin fans and allows them to be powered directly from the power supply’s S-ATA connectors. Combined with the existing NA-SYC1 y-cables, the NA-SAC5 is ideal for powering multiple high-wattage fans without risking damage to the motherboard fan header.
