Small white syringe of grey thermal paste with grey cap

Prolimatech

Prolimatech PK-3/PROLIM-5G thermal paste 5g

SKU CH-VQW7-Z0TN2 MPN PK-3/PROLIM-5G

High-conductivity nano-aluminium thermal paste with low resistance and long-term stability, non-corrosive and ready to use without burn-in

  • High thermal conductivity improves heat transfer from CPU or GPU
  • Low thermal resistance reduces temperature rise under load
  • Long-term stability maintains performance without drying out
  • Non-corrosive formula protects metal surfaces and needs no burn-in time

High-conductivity nano-aluminium paste

Prolimatech PK-3 thermal compound uses nano-aluminium particles to deliver high thermal conductivity and low resistance between CPU or GPU dies and their coolers. The non-corrosive formula is electrically safe and requires no burn-in period before reaching full performance. It suits enthusiasts and system builders who want reliable heat transfer without the mess or risk of liquid-metal alternatives.

Long-term stability and easy maintenance

The compound maintains consistent viscosity over extended use, resisting pump-out and dry-out so thermal performance stays stable through many thermal cycles. Low thermal resistance helps keep component temperatures down under sustained loads, which can reduce fan speeds and overall system noise. The 5-gram syringe provides enough material for multiple applications or reapplications during cooler swaps.

Questions about this item

How do I apply the PK-3 nano aluminium compound correctly, and what common mistake should I avoid?

Apply a pea-sized dot or thin line on the centre of the CPU heat-spreader; the cooler pressure spreads it evenly. Avoid manually spreading with a card, which traps air bubbles and raises thermal resistance.

Will the PK-3 compound dry out or require re-application after extended use?

The formula is engineered for long-term stability and does not require a burn-in period. Under normal operating temperatures it maintains consistency for years, so re-application is only needed if the cooler is removed.
