Ribbed Aluminum Cooling Heat Sink Set , 3-Piece Thermal Heatsinks with Auto -Adhesive Tape for Single-Board Computer

Features: Defined 4B Board Fit: This three piece heat sink set is designed for 4B computer boards, giving chip areas dedicated cooling for maker builds, workshop stations, and embedded projects. Finned Aluminum Cooling: Aluminum alloy construction and raised fin geometry help release heat through passive airflow, supporting steadier board use without wires, added power draw, or moving parts. Three Piece Coverage: Mixed size heat sinks cover multiple hot spots across a board, creating fuller cooling coverage than relying on a single small sink during compact builds. Adhesive Backed Install: Each piece uses adhesive backing for direct placement on compatible chips, helping you add cooling during repairs, upgrades, or recent assemblies without screws. Compact Set Details: An anodized finish, slim component shape, and three piece pack keep this set easy to place for controller projects, coding setups, or hobby electronics workspaces.
