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 (<60°C). Unlike many cheap voltage converters, the NA-VC1 has been carefully tested for product safety and EMC compliance. Carrying CE, UKCA and UL certifications and meeting all applicable standards (EN 62368-1, EN 55035 and EN 55032), it is a safe, quality device through and through.

Suggested retail price is EUR/USD 24.90. For more information, visit the product page.

Don't create problems where there are none.

Most of those cheap step down converters implement manufacturer datasheet 1:1 and are calculated right and are totally safe. Don't venture into a territory you have no basis for your claims Noctua.

Instead of making worse energy losses, not stating your device efficiency make a greater 24V native fan stack, or even better, make them universal 12-24V switchable.

The inside is probably the same cheap step down converter anyway, just on a premium package at 100x the cost :D

From what I recall seeing the insides of other Noctua stuff like their fan splitter, it won't be the cheap OEM garbage but something properly built with all the necessary protections inside (extra caps, fuses, etc).

So they basically selling overpriced LM7812/(or TA7812 alike) (with 2 CAPs + 1 Diode) to people, who cant make/solder their own.

From what I recall seeing the insides of other Noctua stuff like their fan splitter, it won't be the cheap OEM garbage but something properly built with all the necessary protections inside (extra caps, fuses, etc).
it does not worth 25$, its basically a "Positive Voltage Regulator" (I bet we will see a LM7812 inside, or TA7812-alike with build-in protections), that requires 2 Caps and 1 Diode, plus they gonna add few current/voltage/thermal fuses for "protection".
People who use 3D printer and know how to hold ironsolder will not buy these, coz for 5$ u can make few of these urself (or buy "OEM garbage"), that will do the job fine.

At 25 bucks a pop, I think I'll just stick to my making my own. Granted, it is a slick little package, but oof...

Looks like they have pwm and tachometer support, not sure about the components though

ye, u can just put these pins into passthrough mode, since PWM only uses Ground, and hall sensor takes 12v (for pull-up) from fan (same as PWM)

Damn all the hate in here. I'm willing to bet they had customers ask for it and or had RMAs due to cheapo ones. Don't hate the player, hate the game!

They sell few-bucks PSU component for 25$, does it solve the problem with "RMAs due cheapo ones" (if this problem exists)? No, because people will still buy a cheap one.
And these things are usually cheap not because they are poorly made, but because the components itself are cheap.

There are companies in every sector that are charging huge markups for the same things. Cars are a great example, take a Toyota, add a Lexus badge and some "luxury amenities" then charge 25-50% more for it. If these things cost $5 to make, then you charge $10 for them. I bet they are low volume, so double that. Then tack on a $5 premium brand charge. The pricing seems about right to me. Hell, if these were an Apple product, they'd cost $50!

if some of apple users (not all apple users) ready to buy 1000$ display stand, it does not mean that all companies should treat every costumer the same way.
Making things like these only damages Noctua brand.

Let's just agree to disagree. A quick Amazon search just brought up some buck converters without fan connectors. Maybe you should make up something comparable and price them out of the business.

nuh its not PC building stuff. People who buy 3D printers, buy full sets, or can easily make 24v-to-12v themself, u only need to put together LM7812, 2 CAPs and 1 diode, or buy premade one and attach a fan connector to output.

Okay, but 24VDC is used outside 3D printers. Some people don't know how to make their own or don't just don't want to make their own. Not everyone is as technically savvy as your average TPU reader.

and people buy and use premade LM7812 and LM7805 converters-stabilizers-regulators, to get stable 12v or 5v from various stable/unstable input voltages (from 7/15v up to 35v).
Where u need only a screwdriver to attach wires. There are also other LMs on market.
