## Description

A tall-profile aluminium heatsink with pre-applied thermal adhesive for easy installation on the Raspberry Pi 3 and other single board computers. The taller 15mm height provides greater surface area for improved heat dissipation compared to shorter heatsinks. Simply peel off the protective film and press firmly onto the processor. In testing, a Raspberry Pi 3 without a heatsink throttled to 0.96 GHz under full CPU load, while the same Pi with this heatsink maintained 1.16 GHz — approximately 20% higher sustained performance. Key Features Pre-Applied Thermal Adhesive – Peel-and-stick installation, no tools needed Tall Profile – 15mm height for maximum passive cooling performance Aluminium Construction – Lightweight with excellent thermal conductivity Universal Fit – Works with any processor or chip that fits the 15×15mm footprint Specifications Dimensions – 15 × 15 × 15mm Material – Aluminium Attachment – Pre-applied thermal adhesive Ideal For Raspberry Pi 3 (and other Raspberry Pi models) Small processor and IC cooling Any chip requiring passive heat dissipation Note: The Raspberry Pi 3 does not strictly require a heatsink — it automatically adjusts clock speed to avoid overheating. This heatsink allows it to maintain higher sustained performance. Most HATs will not fit on top with the heatsink installed, and the taller profile may not be compatible with all enclosures.
