Comparing Heatsink Material and Compatibility
Material Composition
Product A consists entirely of copper shims, offering uniform thermal properties across all twenty pieces. Copper generally provides higher thermal conductivity than aluminum. Product B mixes materials, including fifteen aluminum pads and five copper shims. Aluminum is lighter but less conductive than copper. If you prioritize maximum heat transfer efficiency per piece, the all-copper construction of Product A has an advantage. However, the mixed approach in Product B may suffice for lower heat loads on specific components.
Compatible Devices
Product A lists compatibility with laptop GPUs, CPUs, VRAM, ICs, and chipset areas. It targets general electronic cooling needs across various devices. Product B explicitly states suitability for Raspberry Pi 5, 4, and 3 boards. It also mentions VRAM, VGA, RAM, IC chips, Mosfet, SCR, Southbridge, and Northbridge. If you are building or upgrading a Raspberry Pi system, Product B is the direct choice. For general laptop or desktop component cooling, Product A covers a broader range of unspecified electronic parts.
Dimensions and Size
Product A shims measure 15x15x0.5mm, which translates to 0.59 inches by 0.59 inches. This provides a consistent footprint for heat dissipation. Product B pads measure 0.55 inches by 0.55 inches with a height of 0.28 inches. The slightly smaller surface area of Product B might limit contact area on larger chips. The difference in thickness is notable, with Product A being thicker. You should verify if the 0.55-inch size fits your specific component spacing, especially on dense Raspberry Pi boards.
Mounting Method
Both kits utilize pre-applied 3M 8810 thermal conductive adhesive tape backing. This feature simplifies installation for both products, as you do not need to apply separate thermal pads or glue. The adhesive ensures secure attachment to surfaces like heat sinks or chassis. Since the mounting mechanism is identical in specification and function, neither product holds an edge here. You get the same ease of installation regardless of which kit you choose.
Cooling Method
Product A is designed for passive cooling of laptop GPUs, CPUs, and other ICs. It relies on conduction to transfer heat away from the component to a larger heatsink or surface. Product B also serves as a passive cooling solution for Raspberry Pi boards and various electronic chips. Both products function as thermal interface materials that bridge the gap between a heat source and a sink. Neither includes fans or active cooling elements. They both serve the same fundamental passive role in your system.
Choose based on device material
Raspberry Pi users needing mixed materials
This kit includes fifteen aluminum pads and five copper shims, designed specifically for Raspberry Pi 5, 4, and 3 boards. The mix allows you to target different heat sources on the board. The pre-applied adhesive simplifies installation. It covers VRAM, IC chips, and Mosfet components effectively for single-board computer cooling needs.
Users needing pure copper for laptops
These shims are made entirely of copper, providing uniform thermal conductivity across all twenty pieces. They measure 15x15x0.5mm, fitting standard laptop GPU, CPU, and VRAM spots. The 3M 8810 adhesive ensures secure attachment. Copper offers superior heat transfer compared to aluminum, making this ideal for passive cooling on high-heat integrated circuits.
DIYers needing uniform copper shims
If you require consistent material properties for a custom cooling project, these all-copper shims are the better choice. They are suitable for VGA RAM and chipset cooling where aluminum might not suffice. The 0.5mm thickness allows for precise spacing adjustments. You get twenty identical pieces, ensuring balanced thermal performance across multiple heat-generating components in your system.

Frequently asked questions
Are the Easycargo copper shims suitable for Raspberry Pi cooling?
These shims are designed for small laptop ICs and VRAM chips, not specifically for Raspberry Pi boards. While you can use them on any flat surface, the 15x15mm size may not match the specific heat sources on a Pi. The dedicated kit offers pre-sized pads for those components.
What is the thickness difference between the two products?
The copper shims are 0.5mm thick, which is thicker than the aluminum pads in the mixed kit. The mixed kit’s aluminum pads have a height of 0.28 inches. This difference affects how much space the heatsink occupies above the component surface during installation.
Does the mixed heatsink kit include adhesive tape?
Yes, the 20-piece copper and aluminum heatsink kit includes pre-applied thermal tape for straightforward installation. The pure copper shim pack also features thermal tape. Both options allow you to stick the cooling pads directly onto components without needing separate adhesive.
Which product is better for cooling GPU VRAM?
The 15x15x0.5mm copper shims are explicitly listed as best for cooling small laptop ICs and VRAM chips. Copper offers higher thermal conductivity than aluminum, making it more effective for transferring heat away from memory chips. The mixed kit is geared toward Raspberry Pi and general ICs.
Can I use the copper shims on a motherboard chipset?
Yes, the shims are compatible with GPUs, laptops, and RAM, which often include chipset components. Their copper material and adhesive backing make them suitable for passive cooling on various small electronic components. Ensure the surface area matches the 15x15mm dimension for proper contact.
How many copper pieces are in the mixed kit?
The mixed kit contains five copper shims and fifteen aluminum pads. This combination allows you to place copper on high-heat sources and aluminum on lower-heat areas. The pure copper pack provides twenty identical copper shims for uniform cooling across all targets.
