Noctua launches 24-to-12V Step-Down Voltage converters for its fans

It’s now easier than ever to use Noctua fans with your 3D printers and other projects

Noctua is a manufacturer of PC fans, and PC fans (mostly) run at 12V. Outside of the world of PC building, fans are made that can functions across a variety of voltage environments, with 24V fans being popular for many electronics.

Noctua, knowing that many of their fans will want to use their products in these environments, have created a new 24V-to-12V DC-to-DC voltage converters that will allow Noctua’s PC fans to be used in 24V environments. This will allow Noctua fans to be used in many 24V products, like 3D printers, with ease, using a compact 31mm x 16mm x 8.5mm converter instead of a more bulky and harder to integrate 3rd party voltage converter. 

Noctua’s voltage converter is made in compliance with all applicable safety standards for this kind of product, including EN 62368-1, EN 55035, and EN 55032. The product is also CE, UKCA and UL certified, and comes with a 6-year warranty from Noctua.

This product will be of interest to users of 24V products like 3D printers (e.g. Creality Ender 3 and CR-10, Anycubic Mega, etc.), or other industrial or automotive products that need replacement fans. Using NA-SYC1 splitter cables or NA-FH1 fan hubs, users of this converter can power multiple fans.

In the future, Noctua does plan to released a dedicated 24V version of one of their 40mm fan designs. This fan is due to release later this year, and will give Noctua fans a 24V option that does not require 24V-to-12V DC-to-DC converters to operate in 24V environments.

Press Release – Noctua Presents NA-VC1 24V DC to 12V DC Step-down Voltage Converter for Fans

Noctua today presented its long-awaited NA-VC1 24 V DC to 12 V DC step-down voltage converter that allows running standard 12 V fans in 24 V environments such as 3D printers or industrial and automotive applications. With a maximum operating temperature of up to 60°C, integrated protection against short-circuits, reverse polarity, overcurrent and overheating, the NA-VC1 is as bulletproof as a voltage converter can be. At the same time, its neat, ultra-compact and lightweight design makes it easy to integrate into virtually any environment.

“Customers have been using our 12 V fans in 24 V environments such as 3D printers for a long time, but often had to resort to cheap, poor quality step-down converters in order to do so”, explains Roland Mossig (Noctua CEO). “As these cheap converters can pose a serious safety hazard, we have created our NA-VC1: A compact, safe and dependable solution for running 12 V fans in 24 V environments.”Many 3D printers are 24 V-based (e.g. Creality Ender 3 and CR-10, Anycubic Mega, etc.) and use 40 or 60 mm fans for cooling the hot-end or the printed part. The NA-VC1 makes it possible to use standard 12 V fans such as the NF-A4x10 PWM, NF-A4x20 PWM or NF-A6x25 PWM in order to achieve quiet, efficient cooling on such printers.

The NA-VC1 is barely larger than a standard 4-pin fan connector (31x16x8.5 mm) and weighs only 6 g. As a result, it can simply be interconnected between the fan cable and the power source, with no need for extra fixation in most applications.

Supporting a total output power of 9 W, the NA-VC1 is fit to run single fans with high power draw or multiple lower power fans that are connected to the device using optional splitter cables (NA-SYC1 or NA-SYC2) or fan hubs like the NA-FH1.

Designed to operate in challenging environments, the NA-VC1 is internally protected against short-circuits, reverse polarity, overcurrent, and overheating by a resettable fuse. It will shut down automatically for protection and can be reset by disconnecting it from the power source in a safe operating temperature (
