20-piece aluminum heatsink kit

This kit supplies twenty 11 mm square aluminum heatsinks with pre-applied 3M 9448a thermal adhesive tape. They are intended for hobbyists and technicians who need to add passive cooling to small integrated circuits such as stepper drivers, voltage regulators or single-board computer processors.

11 x 11 x 5 mm footprint

Each heatsink measures 11 mm by 11 mm in plan and stands 5 mm tall, so it only fits components whose top surface matches or exceeds that area. Verify the exact dimensions of the target chip before purchase; a larger or smaller die will not make proper contact.

Adhesive mounting, no extra hardware

The included double-sided thermal tape bonds directly to the component, eliminating the need for screws, clips or thermal paste. This keeps the assembly low-profile for tight enclosures such as 3D printer control boards, Raspberry Pi or Banan Pi cases, while still allowing careful removal with a blade if rework is required.

Questions about this item

How much surface area does the 11 x 11 x 5 mm block give a small chip like the A4988?

The 11 mm square base covers the driver completely while the 5 mm fins add extra radiating area, so the A4988 runs cooler under load.

What does the included 3M 9448a tape do for thermal transfer?

The 3M 9448a double-sided thermal tape bonds the aluminium to the chip and conducts heat across the interface without screws or paste.

Will the 11 mm height clear low-profile motherboard heatsinks or a Raspberry Pi case?

At 5 mm tall the heatsink fits under most board shields and Pi cases, leaving enough room for airflow.
