Hardware Cooling You can now download 3D CAD models of Noctua fans, but the company warns they 'will not perform well when printed' News By Andy Edser published 28 April 2026 Still, a useful resource if you're designing around Noctua air-movers.

You won't be able to print a straight-up clone, though, as the company has deliberately modified some of the crucial details, like the fan impeller geometries.Noctua says the CAD models are provided on an "as is" and "as available" basis, with no warranties or guarantees, and that the models have been released "solely for reference, visualisation, and integration purposes."Further to this, Noctua has clarified on X that people can "gladly" print the models, but that certain key details have been changed to protect its intellectual property. "Due to these modifications, these models will not perform well when printed," the company states. Noctua also says the 3D models may not be used for "the manufacture, reproduction, or commercialisation of the products they represent," and this seems to be the crux of the matter. While hobbyists might do well to learn from everything Noctua does in its fan design, competing companies would likely look at a fully-accurate file with great interest.People can gladly print the models, of course, but please keep in mind that they are intended for mechanical design and visualisation purposes only. As stated on our website: "These public 3D CAD models accurately represent mounting dimensions as well as the overall external…April 27, 2026In a further reply discussing the building of fans, Noctua also says that: "Printing your own fan impeller and frame are one thing, building the motor and bearing as well as assembling everything with the required precision is another."Given that its latest NF-A14x25 G2 fan design took nearly a decade to develop, and that the fan/shroud tolerances are incredibly tight as part of the design (with a liquid-crystal polymer material used to achieve it), knocking up one of those would be... well, you'd likely need more than a CAD file, anyway.Still, the 3D models are still likely to be of great use for those creating their own projects around the dimensions of Noctua hardware. And given that two Noctua models make for some of the top picks in our best PC fans guide, it's no surprise that the company wants to hold on to some aspects of its IP to prevent mass-produced imitations. window.sliceComponents = window.sliceComponents || {}; externalsScriptLoaded.then(() => { window.reliablePageLoad.then(() => { var componentContainer = document.querySelector("#slice-container-newsletterForm-articleInbodyContent-WZKyQwpMxid4BWqGNdw6cn"); if (componentContainer) { var data = {"layout":"inbodyContent","header":"The biggest gaming news, reviews and hardware deals","tagline":"Keep up to date with the most important stories and the best deals, as picked by the PC Gamer team.","formFooterText":"By submitting your information you agree to the <a href=\"https:\/\/futureplc.com\/terms-conditions\/\"…
