EN-Labs 10pcs Aluminum Heatsink 8.8x8.8x5mm 3M 8810 diy cooling

Aluminium Heatsink Kit

This pack contains ten aluminium heatsinks sized 8.8mm x 8.8mm x 5mm, each supplied with a pre-cut piece of 3M 8810 thermally conductive adhesive tape. The square profile suits small surface-mount chips such as stepper drivers, voltage regulators and single-board-computer processors. The pressure-sensitive tape bonds on contact without a cure cycle, simplifying installation for hobbyists and repair technicians.

Adhesive Interface Limits

The 3M 8810 tape provides a thermal conductivity of .6 W/m-k and doubles as an electrical insulator, so it can be applied directly to exposed circuitry. Because the bond relies on pressure alone, the mating surfaces must be clean and reasonably flat for the adhesive to wet properly. The tape softens slightly to accommodate minor unevenness, but large gaps or heavily textured packages will reduce thermal transfer.

Capacity and Headroom

Ten heatsinks give enough units for a typical 3D-printer control board or a cluster of Raspberry Pi, Banana Pi or Orange Pi modules. Each sink adds a modest fin area to dissipate heat from low-power ICs such as the A4988 stepper driver or similar voltage regulators. The small 5mm height restricts airflow in tight enclosures, so sustained high-current loads may still require active cooling or larger heatsinks.
