ALLNET Universal Heat Sink 25mm x 17mm for Banana Pi, FriendlyElec, Lemaker (HeatSink_25x17x3)

The ALLNET Universal Heat Sink is a compact, passive cooling solution designed for single-board computers like Banana Pi, FriendlyElec, and Lemaker. Measuring 25mm x 17mm x 3mm, this aluminum heat sink effectively dissipates heat from CPUs, GPUs, RAM, or other ICs, ensuring stable performance and extended component life. The low-profile design makes it ideal for space-constrained enclosures.

Advantages

This heat sink offers easy installation with pre-applied thermal adhesive tape—simply peel and stick onto the target component. Its natural aluminum finish provides efficient passive cooling without the need for fans, making it silent and maintenance-free. The optimized thermal resistance enhances system stability, especially during prolonged use or in warm environments.

Suitable for

• Banana Pi single-board computers
• FriendlyElec development boards
• Lemaker SBCs
• Other small form factor devices requiring passive cooling
