Who it fits

Key specs explained for this kit

Material: 99.9% pure copper

This value indicates the metal composition used for the heatsinks. High-purity copper transfers heat away from components faster than lower-grade alloys. You benefit from steady temperatures during intensive tasks like 4K video playback. When shopping, compare this against aluminum options, which are lighter but less efficient at moving heat.

Mounting Type: Thermal Conductive Adhesive Tape

This method secures the heatsink using a sticky pad rather than screws or clips. It simplifies installation on the Raspberry Pi 5 by eliminating tools. You gain a clean look with no protruding hardware. Compare this to screw-mounted coolers, which offer adjustable pressure but require more precise alignment and additional mounting hardware.

Compatible Device: Raspberry Pi 5

This specification confirms the kit is designed specifically for the Pi 5 board. The laser-cut shapes match the CPU, RAM, and USB-C ports exactly. You avoid cutting or adjusting the metal to fit. When buying, ensure your board version matches, as previous Pi models have different port layouts and component sizes.

Adhesive Rating: 15W/m·K

This number measures how well the thermal glue conducts heat. A rating of 15W/m·K is strong for passive cooling adhesives. It ensures heat moves from the chip into the copper efficiently. Compare this to standard pads, which often have lower ratings. Higher ratings generally mean better temperature control for your processor.

Heatsink Sizes: 17x17x5mm to 5x5x5mm

The kit includes five different dimensions to cover various chips on the board. Larger sizes handle the CPU, while smaller ones fit RAM or controllers. You get comprehensive coverage in one package. When comparing kits, check if all your hot spots are included. Missing sizes may leave certain components undercooled during heavy workloads.

Design and build details

According to the listing, this kit uses 99.9% pure copper for all ten heatsinks. This material choice prioritizes rapid heat transfer from the Raspberry Pi 5 components. You do not need tools for installation. The mounting method relies on thermal conductive adhesive tape included in the box. This tape bonds directly to the chip surfaces, eliminating the need for screws or clips. The adhesive is rated at 15W/m·K, which suggests strong thermal coupling between the metal and the silicon.

The set contains five distinct sizes: 17x17x5mm, 15x10x5mm, 13x12x5mm, 6x6x5mm, and 5x5x5mm. These dimensions are laser-cut to fit the CPU, RAM, and USB-C ports on the Pi 5 board. The listing notes that no cutting or adjustments are required. This precise fit ensures the metal sits flush against the heat sources without obstructing nearby connectors. The overall package weighs 1.06 ounces and measures 2 inches in length, 1 inch in width, and 3 inches in height.

This passive design suits users who want silent operation without fans. The lack of moving parts means zero noise and minimal power consumption. However, you must ensure the Pi 5 board is clean before application. The adhesive creates a permanent bond, so positioning matters during installation. The kit does not include the Raspberry Pi 5 board itself. You only receive the copper sinks and the necessary thermal tape to complete the upgrade.

Setup and everyday use

Installing this kit requires no tools. The listing specifies a thermal conductive adhesive tape for mounting. You apply the included premium heat-conductive glue, rated at 15W/m·K, to bond the copper pieces directly to the board. This method provides instant bonding and a long-lasting hold. The design is laser-cut to match the Raspberry Pi 5 layout. It fits the CPU, RAM, and USB-C ports precisely. You do not need to cut or adjust the heatsinks. The kit includes five distinct sizes: 17x17x5mm, 15x10x5mm, 13x12x5mm, 6x6x5mm, and 5x5x5mm. This variety ensures coverage for all major heat-generating components. The total weight is 1.06 ounces, making it a lightweight addition. In daily use, the 99.9% pure copper material facilitates ultra-fast heat dissipation. This helps keep your Pi 5 cool during intensive tasks. The listing notes it handles 4K/60Hz workloads effectively. You benefit from steady temperatures without active fans. The passive design relies entirely on the copper’s thermal properties. Ensure you clean the board surface before application for optimal adhesive performance. The kit does not include the Raspberry Pi 5 board itself. You must provide the single-board computer separately. The straightforward installation process suits users who prefer a clean, tool-free setup. The precise fit minimizes air gaps, enhancing thermal transfer efficiency. This setup is ideal for silent operation needs.

Before you buy this kit

You need to verify your Raspberry Pi 5 board is present, as it is not included. The heatsinks use thermal conductive adhesive tape for mounting. You must apply the included 15W/m·K glue for proper bonding. This method offers instant hold but requires careful alignment. Unlike active CPU air coolers, this passive solution relies on copper’s natural conductivity. It suits users who prefer silent operation without fans. You should check that the five distinct sizes match your specific component layout. No cutting or adjustments are needed due to the precise laser-cut design. For upkeep, keep the copper surfaces clean to maintain thermal efficiency. This kit fits well alongside other passive cooling options for compact builds. It is ideal for 4K/60Hz workloads where heat dissipation is critical. You do not need tools for installation, making it straightforward for beginners. Ensure you have the thermal paste ready before starting the setup process.

Check before you buy

• Confirm you own a Raspberry Pi 5 board
• Verify the five heatsink sizes fit your components
• Check for included thermal conductive adhesive tape
• Ensure no active fans are required for your setup
