Prolimatech PK-3 Nano Aluminum

Prolimatech doesn't consistently publish a specific W/mK figure for PK-3 across its own materials. This needs manufacturer confirmation before it's used in filters or direct numeric comparisons.

An aluminum nano-particle based compound, a different approach from the carbon-based, silicone-based, and liquid metal options elsewhere in this category, aimed at high thermal transfer without electrical conductivity.

PK-3 applies with a standard, workable consistency typical of metal-particle-based pastes in this bracket, available in small syringe sizes up to a bulk 30g option for repeated use across multiple builds.

Non-conductive, despite its aluminum nano-particle content, since the particles are bound into a non-conductive base compound rather than present as free metal.

Manufacturer-rated interval isn't consistently published. Confirm against current Prolimatech documentation before publishing a specific timeframe.

Against Arctic MX-4, covered elsewhere on this site, PK-3 offers a different compound chemistry at a comparable mainstream-to-high-end positioning. Against Thermal Grizzly Kryonaut, PK-3 lacks a confirmed conductivity figure for direct comparison, a gap worth closing before recommending one over the other on paper.

Builders who want an aluminum nano-particle compound as an alternative to carbon-based or silicone-based pastes.

Bulk buyers or shops needing the 30g size across multiple builds.

Not for: Builders who need a verified conductivity figure to compare directly against Kryonaut or TFX before purchase.

Not for: Extreme overclocking setups needing liquid metal-tier conductivity.

Thermal Conductivity: Not consistently published by Prolimatech.

Reapplication Interval: Manufacturer-rated interval not consistently published.
