Unlike thermal pastes and most other thermal pads, whose performance decreases over time due to extrusion, delamination, cracking or other degradation processes, Carbice pads’ performance improves over the first hundreds or even thousands of heating and cooling cycles. This is achieved through a strong mechanical structure, a phase change polymer coating and carbon nanotubes that gradually adapt to the surface microtopography, increasing heat transfer efficiency. Once this “activation” stage is complete, the Noctua NT-CP1 will provide stable, maintenance-free operation for many years.
Unlike other carbon or graphite based thermal pads, which can be brittle, slippery and highly conductive, Carbice products are durable, safe and easy to install. With an aluminum base, Noctua NT-CP1 turns out to be reliable and convenient for subsequent dismantling. Installation requires only three steps: remove the protective layer, press, remove the second protective layer. The slightly tacky polymer coating holds the gasket to the processor after pressing and provides electrical insulation between the contact surfaces as long as the polymer layer is not damaged.
Manufacturing graphite or graphene gaskets often has a high carbon footprint due to energy-intensive raw material extraction or high-temperature synthesis processes. Manufactured by Carbice Corporation in the US, NT-CP1 is created using recycled aluminum and carbon-containing waste gases, the latter used as feedstock to grow carbon nanotubes using an energy-efficient process at low temperatures. The Noctua NT-CP1 thermal pad is recycled with regular aluminum, supporting circular economy principles.
The version for AMD AM4 and AM5 platforms has been carefully optimized and tested to provide the best performance with AMD Ryzen CPUs and APUs. With a thickness of 90 microns and a length and width of 33 x 33 mm, the spacer is ideal for processors that fit into these sockets.
