These heatsinks are specially designed for Raspberry Pi boards (2, 3B, 3B+), whose function is to cool Raspberry chips, improving performance and reducing the risk of hardware failure due to overheating.
The heat sinks feature a self-adhesive 3M heat conductive silk ribbon on the back (may or may not). That way you simply remove and paste on the chips of the Raspberry Pi plate.
