Five aluminium heatsinks for small components

This pack contains five aluminium heatsinks measuring 40 by 40 by 20 millimetres each. They are designed to fit ICs, CPU modules, LED drivers and power components that need passive cooling. Hobbyists, repair technicians and embedded-system builders can use them to dissipate heat without adding a fan.

Passive cooling with no noise or power draw

The fins rely on natural convection so they run completely silent and draw zero power. Aluminium construction spreads heat quickly across the 20 millimetre height. Performance depends on airflow inside the enclosure and the thermal interface material used. Buyers needing active cooling or larger surface areas should consider other solutions.

Questions about this item

How do I attach the 40x40mm aluminum heat sink to a CPU or power component, and what step is often missed?

Clean both surfaces, apply a thin layer of thermal paste or use a thermal pad, then press the finned side down firmly; the step often missed is removing any protective film from the base before mounting.

What maintenance will these 20mm high cooling fins need over time?

Dust builds up between the fins and reduces airflow; use compressed air or a soft brush every few months to clear the channels without bending the thin aluminum.
