Noctua will distribute a thermal pad from Carbice, based on carbon nanotubes and already tested on satellites. AMD also includes the component in a special edition of its Ryzen 7 5800X3D.
The NT-CP1 AM5/4, Noctua version of the Carbice IP90, arrives on the DIY market after years spent in sectors where thermal paste is not a reliable option: aerospace, satellites, critical infrastructures.
Concretely, we replace the tube of paste with a square which we place on the processor, without syringe or spreading.
His promise takes the dough in reverse: instead of drying over the years (effects of pump-out and of dry-out well known), the pad sees its contact improve with each thermal cycle, the nanotubes better matching the micro-asperities of the metal. All on a sheet of aluminum which serves as a framework and avoids the slippery side of competing graphite pads.
Its price increases on September 1st, take advantage of it!

The pad does not arrive out of nowhere on the PC side: Carbice has already been equipping certain pre-assembled PCs from CyberPowerPC since the end of 2025, where the Ice Pad is offered as an upgrade option. It was this first step back in the field that undoubtedly convinced AMD and Noctua to bring the technology on board.
First CPU sold in a box with a nanotube pad
To validate the technology on the consumer side, AMD has announced that it will slip a Carbice Ice Pad into the box of its Ryzen 7 5800X3D 10th anniversary edition of the AM4 platform.

This processor will be marketed at $349 from June 25, 2026, compared to $449 at its original launch in 2022, and the box arrives without a cooler, which changes the calculation a little.
On the pure DIY side, Noctua will exhibit the NT-CP1 AM5/4 on its stand at Computex 2026 (June 2 to 5 in Taipei) before going on sale in September. The retail price has not been communicated, and that’s the whole point: a technology billed like a premium paste or like a real upgrade for enthusiasts.
To give an order of magnitude, the graphite pads already on the market cost around 15 to 25 dollars each (Thermal Grizzly Carbonaut, Kyrosheet Graphene). It is in this range that we will expect the NT-CP1 if it is really aimed at the enthusiast, beyond that, Noctua will have to justify the difference by the announced lifespan.
For those who mount a PC on AM4 or AM5 and hate the idea of dismantling their cooler in five years, the NT-CP1 has a concrete argument, provided that Noctua does not weigh down the bill in September.
