Vienna, 12 November 2026 – Noctua today introduced the new NT-CP1 AM5/4 carbon nanotube thermal pad for AMD AM5 and AM4 processors. Leveraging Carbice’s novel, space-grade carbon nanotube technology, the NT-CP1 is a premium-quality, easy-to-apply thermal pad that offers superior long-term stability for peace of mind.
While thermal pastes and most other thermal pads gradually lose performance over time due to pump-out, delamination, cracking and other degradation effects, Carbice® pads keep improving their performance over the first few hundred to a few thousand thermal cycles. This is possible thanks to the pad’s robust mechanics, phase-change polymer coating and carbon nanotubes that incrementally conform to surface microstructures, enhancing the heat transfer rate with time and thermal cycling. Once this initial activation phase is completed, the NT-CP1 maintains stable, maintenance-free performance for years and years. As such, it is ideal for everyone who seeks to rule out thermal issues due to degradation and never wants to bother with reapply paste again.
"Carbice pads offer a unique combination of ultimate performance stability and convenient installation. This makes the NT-CP1 the perfect choice for everyone who’s looking for a thermal pad that’s super easy to apply and never needs to be replaced."
Roland Mossig
CEO of Noctua
Unlike other carbon or graphite-based thermal pads that can be brittle, slippery and highly electrically conductive, Carbice® pads are sturdy, safe and easy to install using a straightforward “peel, press, peel” process. The NT-CP1’s aluminium backbone makes it surprisingly robust and easy to remove. The slightly tacky polymer coating helps to keep the pad in place once pressed onto the CPU and ensures that the contact surfaces are electrically non-conductive before usage unless the polymer layer is penetrated.
Whereas graphite and graphene-based pads tend to have a high carbon footprint due to energy-intensive mining or high-temperature growth processing, the NT-CP1 is manufactured by Carbice Corporation in the United States out of recycled aluminium and waste carbon gas that’s used to grow carbon nanotube forests in an energy-efficient, low-temperature process. The NT-CP1 pad can be recycled through standard aluminium recycling and offers a complete path to waste circularity.
“Carbice’s carbon nanotube thermal pads were first built for spacecraft. Now, with Noctua, every PC builder can put that same technology in their system. Noctua has spent two decades earning the trust of builders who care about every detail, and they share our belief that great engineering should last. The NT-CP1 is better for your hardware and better for people and our planet, and we couldn’t ask for a better partner to deliver it.”
Baratunde Cola
CEO and founder of Carbice
The AM5/4 version has been carefully fine-tuned and validated for optimal performance on AMD Ryzen™ CPUs and APUs. With its ultra-thin 90µm profile and precut 33x33mm size, it fits both AM5 and AM4 socket processors.
Overall, the NT-CP1 Carbice® pad is an innovative premium choice for users looking for a clean, convenient and environmentally friendly thermal interface material solution with reliable long-term performance, space-grade dependability and zero maintenance.
Suggested retail price
The manufacturer’s suggested retail price is EUR 24.95 / USD 24.95.
Availability
The NT-CP1 AM5/4 is available as of today via Noctua’s official Amazon stores. Other sales partners will receive stock shortly.
