Goodbye thermal paste? Noctua bets on technology that improves over time

Noctua and Carbice

Noctua and Carbice have announced a long-term strategic partnership aimed at the hardware enthusiast market. The agreement states that the Austrian company will become the exclusive distributor of the thermal pads developed by Carbice for the retail channel, also supporting the American company in future research and development activities dedicated to new cooling solutions.

Carbice is known for developing thermal interface materials (TIM) based on vertically aligned carbon nanotubes, a technology already used in particularly demanding contexts such as aerospace, critical infrastructure, and satellite applications, where reliability and durability are essential requirements.

According to the two companies, the main distinguishing feature of Carbice pads lies in their long-term behavior. Unlike traditional thermal pastes and many other pads on the market, which can lose efficacy over time due to phenomena like pump-out, delamination, microfractures, or other forms of mechanical degradation, the solution developed by Carbice can progressively improve its thermal performance throughout the product's lifecycle.

Structure of the Carbice Pad

This result is achieved thanks to the particular structure of the carbon nanotubes, which tend to gradually adapt to the micro-roughness of the contact surfaces during heating and cooling cycles. Over time, the contact between the heatsink and the processor becomes more effective, promoting increasingly efficient heat transfer.

The company also emphasizes how its technology differs from traditional graphite or carbon-based pads. The structure integrates a central aluminum support encapsulated between two layers of carbon nanotubes, while a special nanometer-scale polymer coating protects the entire surface. This configuration aims to ensure greater mechanical robustness, better stability during installation, and easier removal compared to other competing solutions. Another declared advantage concerns electrical insulation, an important feature during assembly and maintenance operations.

The first product born from the collaboration is named Noctua NT-CP1 AM5/4, a thermal pad specifically designed for AMD Ryzen processors based on AM5 and AM4 sockets. The product is scheduled for release in September 2026. At this time, no details regarding price or availability in specific markets have been disclosed.

Furthermore, it is worth mentioning that AMD has also chosen to include a thermal pad developed by Carbice in the bundle of the new Ryzen 7 5800X3D 10th Anniversary Edition.
