50-piece aluminium heatsink kit

This kit contains fifty 8.8 mm square aluminium heatsinks, each 5 mm tall, supplied with pre-applied 3M 9448 thermal tape. They are intended for hobbyists and technicians who need to add passive cooling to small integrated circuits on motherboards, graphics cards, 3D printer drivers or single-board computers. The adhesive backing allows quick installation without separate thermal compound or mechanical fasteners.

8.8 mm footprint matches common driver chips

The 8.8 × 8.8 mm base is sized to fit packages such as the A4988 stepper driver found on many 3D printer control boards. Verify that the target component’s top surface is no larger than this footprint so the heatsink sits flat and the tape makes full contact. If the chip is taller than 5 mm the heatsink will still attach, but clearance above the board must be checked in the target device.

Passive cooling with no fan noise

Aluminium spreads heat from the component into the finned body, where natural convection carries it away. Because there are no moving parts, the heatsinks add zero acoustic noise and draw no electrical power. The 3M 9448 tape maintains its bond through normal thermal cycling, yet can be removed with a thin blade if the heatsink needs to be repositioned or replaced.

Questions about this item

What does the 8.8 mm height mean once the heatsink is on a chip?

The 8.8 mm square footprint and 5 mm fin height sit directly on the component, adding minimal clearance while the aluminium body spreads heat from the die into the surrounding air.

How does the 3M 9448 tape affect thermal performance?

The pre-applied 3M 9448 thermal tape bonds the aluminium fins to the chip and conducts heat across the interface, replacing a separate paste or pad step.

What physical space do I need to fit one of these 50 pieces?

Each piece measures 8.8 mm by 8.8 mm in plan and stands 5 mm tall, so verify the target chip and nearby components leave at least that much room.
