This 20×20×6mm heatsink is a compact aluminium heat sink for cooling CPU, GPU, RAM, LED, BGA, and IC packages in embedded computing and DIY electronics builds, supplied as a pack of two. The 20×20×6mm footprint covers a wide range of common IC package sizes including SOIC, QFP, and small BGA. This 20×20×6mm heatsink attaches with self-adhesive thermal tape for a clean, tool-free installation. As a result it suits Raspberry Pi, Arduino, and microcontroller-based projects where multiple chips need passive heat management in a compact space. Key Features of the 20×20×6mm Heatsink Dimensions: 20 mm × 20 mm × 6 mm — low-profile, suits most enclosures and HAT stacks Aluminium with parallel fins for good airflow and heat dissipation Self-adhesive thermal pad — quick press-fit installation, no tools needed Suitable for CPU, GPU, RAM, LED, BGA, and IC packages Pack of 2 — cover multiple hot chips in a single order Use Cases Raspberry Pi CPU and USB/LAN controller cooling in passively cooled builds GPU and RAM thermal management on single-board computers LED driver cooling in maker lighting and display projects General passive cooling for any IC running warm in a compact build Works Well With 9×9×12mm Heatsink for A4988/DRV8825 — smaller 9×9mm heatsink for stepper driver ICs on the same board 50mm Axial Cooling Fan 5V/12V/24V — add active airflow with a 50mm fan when passive cooling is not sufficient Project Ideas & Tutorials Motor Heat Sink: When and How to Add Cooling — Zbotic — explains when heatsinks are needed and how to attach them to motor drivers and ICs DRV8825 Stepper Motor Driver Arduino Tutorial — Last Minute Engineers — demonstrates heatsink selection and mounting for compact IC packages Package Contents 2 × 20×20×6mm aluminium heatsinks
