Unique-Bargains Aluminum Heatsink 9 x 9 x 12mm Silver 10pcs

Compact Aluminium Heatsinks for Small Chips

These 9 x 9 x 12 mm aluminium heatsinks are designed for cooling memory chips, stepper motor drivers and similar small components that lack factory cooling. The pack contains ten pieces, each with pre-applied thermal conductive adhesive tape for quick installation on clean, dry surfaces. They suit hobbyists and repair technicians adding passive cooling to 3D printer electronics or embedded boards. Builders needing larger surface areas or active fan mounts will need a different solution.

Passive Thermal Performance and Airflow Dependency

The heatsinks rely entirely on case or ambient airflow to dissipate heat; they do not move air themselves. Aluminium alloy construction spreads heat from the component into the 12 mm tall fins, but temperatures will rise without forced ventilation. The supplier recommends pairing them with a separate cooling fan, which is not included. No power draw or noise is generated by the heatsinks themselves, making them silent additions to any build.

Pre-Applied Adhesive Tape Simplifies Mounting

Each heatsink ships with thermal conductive adhesive tape already attached, removing the need for separate thermal paste or pads. The tape provides both mechanical bond and thermal interface when pressed onto a cleaned chip surface. No additional brackets, clips or software are supplied; installation is purely mechanical. The ten-piece quantity covers multiple drivers or memory modules in a single purchase.
