Noctua has introduced the NT-CP1 AM5/4, a carbon nanotube thermal pad for AMD AM5 and AM4 processors, as a possible alternative to thermal paste. The announcement was reported on 12 November 2026: TechPowerUp published the press release at 10:25 UTC and Tom's Hardware followed at 13:04 UTC.

What Noctua says it does

Noctua says thermal pastes and most other thermal pads gradually lose performance through pump-out, delamination, cracking and other forms of degradation. The NT-CP1 is positioned as a response to that problem.

According to the company, the pad uses carbon nanotubes originally developed for aerospace applications. Noctua says these gradually adapt to microscopic surface imperfections, improving heat transfer over repeated heating and cooling cycles. It also says Carbice pads keep improving their performance over the first few hundred to a few thousand thermal cycles.

Noctua describes the NT-CP1 as a premium-quality, easy-to-apply pad with superior long-term stability. These are marketing descriptions, and the material supplied includes no benchmark figures.

Price and evidence

The only price indication comes from the Tom's Hardware URL slug, which points to US$24.95. The summaries we have seen do not confirm that figure, so treat it as provisional. UK pricing and on-sale dates are also unknown.

In our reading, both reports relay Noctua's claims, and neither includes independent measurements of thermal performance or longevity. Every performance statement above is therefore the manufacturer's own.

Why it matters

For AM5 and AM4 owners, a pad that does not pump out or dry up would mean less need to reapply paste. That benefit rests entirely on Noctua's claims until reviewers measure temperatures against good pastes and test the pad over time.

What we do not know yet

  • The confirmed price, including UK pricing, and when and where it will be on sale
  • How it performs against good thermal pastes in independent temperature tests
  • Whether the pad is reusable after a cooler is remounted
  • Whether it works with all coolers, including non-Noctua models
  • Whether Noctua will offer versions for Intel sockets
  • The pad's thermal conductivity or any other measured specification
  • How long it takes to reach peak performance
