The RHS-03 dual heatsink set is a passive cooling kit designed specifically for the Raspberry Pi single-board computer family, providing effective thermal management for the processor and other heat-generating chips without requiring a fan or external power. The set includes one large heatsink measuring 14mm × 14mm × 6mm and one small heatsink measuring 9mm × 9mm × 5.2mm, allowing users to match the cooling surface to the size of the target component. This makes the kit suitable for the main SoC as well as smaller chips such as RAM, USB controllers, or Ethernet controllers on Raspberry Pi 2, 3, and 4 boards.

The 3M adhesive thermal heatsinks are made of aluminum, a material widely used in passive cooling because it offers a good balance of thermal conductivity, low weight, and low cost. Each heatsink comes with a pre-applied 3M thermal conductive adhesive tape on its underside, eliminating the need for thermal paste, screws, or tools. Installation simply involves cleaning the target chip, peeling the protective liner from the adhesive, and pressing the heatsink firmly into place. This self-adhesive mounting method is convenient for beginners and allows the heatsinks to be repositioned or removed if needed.

Passive heatsinks of this type help reduce the risk of thermal throttling and extend the service life of Raspberry Pi boards, particularly during sustained workloads such as home automation servers, media centers, and lightweight NAS builds. The dual-size configuration provides flexibility, while the low-profile design maintains compatibility with most Raspberry Pi enclosures. With a thermal resistance of approximately 25°C/W for comparable dual sets, these heatsinks offer a practical, silent, and maintenance-free cooling solution.
