Noctua and Prusa Release Beige and Brown PETG Filament for PC Builds

Noctua fans are famous for two things: moving a lot of air and looking beige while doing it. Now PC builders who also run a 3D printer can match their custom parts to those fans exactly.

Prusa Research has partnered with Noctua to release two new Prusament PETG filaments: Noctua Beige and Noctua Brown. The spools are color-matched to Noctua's signature fan and heatsink palette. That means printed GPU shrouds, cooler covers, and case brackets can finally blend in instead of sticking out in bright red or blue.

This is PETG, not PLA. PETG survives higher temperatures and resists impacts better, which matters when a part sits next to a hot VRM or inside a cramped chassis. Noctua CEO Roland Mossig said the company heard from users who wanted a tougher material for custom PC parts. The earlier PLA versions worked for non-structural pieces, but PETG opens up functional enclosures and ducting that see real heat.

Prusa promises tight dimensional tolerances, around plus or minus 0.02mm, and NFC-enabled spools so compatible printers automatically load the right profile. Each spool costs $32.99 on Prusa's website.

The timing makes sense. Custom loop builds, cable combs, and radiator shrouds are popular mods, and sourcing matching filament has always been a guesswork game. With an official color-matched option from the printer brand itself, the guesswork disappears.

If you run Noctua cooling and own a Prusa, these spools are an easy recommendation. Even if you use a different printer, the color data is useful: you now know exactly which hex values to hunt for on generic PETG sites.
