Which one should you choose?
Choose MECCANIXITY 15x15mm 1mm Copper Shims if
- You need a thicker shim to bridge a larger gap between the heat source and the heatsink base.
- Your target component has a smaller surface area, such as a specific CPU IHS or small chip.
- You prefer a more rigid copper pad that may offer slightly better structural stability.
Choose MECCANIXITY 20x20mm 0.3mm Copper Shims if
- You require a larger contact surface to spread heat over a wider area, like a GPU core.
- Your hardware has very tight clearance, requiring the thinnest possible profile.
- You want to maximize the copper-to-component contact area for improved heat dissipation.
Verdict: The 15x15mm 1mm shims are better for filling larger vertical gaps on smaller components. The 20x20mm 0.3mm shims suit applications needing a broad, low-profile contact patch. Select the size and thickness that matches your hardware's physical constraints.
Shim Size and Thickness Comparison
Surface Area Coverage
Product B offers a larger footprint at 20mm x 20mm, providing more surface area for heat dissipation than Product A’s 15mm x 15mm design. This extra area allows Product B to spread heat over a wider section of your hardware. Product A’s smaller dimensions make it better suited for compact components or tight spaces where a larger shim would not fit. You should choose Product B if you need maximum coverage for larger chips or memory modules. Product A remains the practical choice for smaller electronic devices or specific spots where space is limited.
Thickness Profile
Product A is significantly thicker at 1mm, which helps fill larger gaps between a heat source and a cooling solution. This added mass may help stabilize temperatures in areas with irregular surfaces. Product B is much thinner at 0.3mm, making it ideal for filling small gaps or acting as a precise spacer. The thinner profile of Product B ensures it sits flush without adding bulk to your build. You should select Product A if you need to bridge a wider distance. Choose Product B for applications requiring minimal height increase or precise spacing adjustments.
Compatible Device Support
Product A is listed as compatible with Desktop Computer CPU. Product B expands this compatibility to include both Desktop Computer GPU and CPU. This broader specification suggests Product B is marketed for use on graphics cards as well as processors. If you plan to use these shims on a GPU, Product B explicitly supports this use case. Product A’s listing focuses solely on the CPU. You should verify your specific hardware requirements, but Product B offers more versatility for different desktop components based on its published compatibility.
Material and Adhesive
Both products share identical material specifications, using high-quality copper with thermal conductive adhesive backing. Each package contains five sets of copper sheets with pre-applied adhesive tape for easy installation. They both withstand temperatures up to 160 degrees Celsius, ensuring durability under heat stress. The cooling mechanism is the same for both, relying on copper’s natural heat transfer properties. Since the core material and mounting method are identical, you do not need to worry about performance differences due to material quality. Both options provide the same reliable thermal conductive backing.
Weight and Density
Both products weigh exactly 0.35 ounces, indicating similar overall mass despite their dimensional differences. This consistent weight suggests the adhesive backing and copper content are balanced similarly in both designs. The weight difference is negligible for most desktop builds, so neither product will add noticeable load to your components. You can install either product without concern for added strain. The identical weight confirms that the manufacturing process maintains consistent material usage across these different size variations, ensuring a uniform feel and installation experience.
Which shim fits your build best
Users with small chip gaps
Choose this 1mm thick shim if your hardware has a larger gap between the component and the heatsink. The 15mm by 15mm footprint fits smaller chips or memory modules. The thicker copper provides a solid bridge for heat transfer where space allows. It works well for desktop CPU or north bridge cooling where precise fit matters more than surface area.
Users needing wider coverage
Select this 0.3mm thick shim if you need to cover a wider area. The 20mm by 20mm size spreads heat over a larger surface, which is ideal for GPUs or larger ICs. The thinner profile fits into tighter spaces while still offering copper conductivity. It is a good choice when you want to cool a broader component area.
Users cooling graphics cards
This product lists compatibility with desktop computer GPUs. The larger 20mm by 20mm surface area helps dissipate heat from graphics card components more effectively than the smaller option. The thin 0.3mm design ensures it does not interfere with surrounding parts. Use this shim to extend the service life of your GPU memory or voltage regulators.

Frequently asked questions
Are these copper shims compatible with desktop GPUs?
Yes, the 20x20mm 0.3mm version is explicitly listed as compatible with GPUs. This makes it suitable for cooling memory modules or small integrated circuits on graphics cards. The 15x15mm 1mm version is designed for desktop systems but focuses on smaller chip gaps rather than broad GPU surfaces.
What is the difference in thickness between the two shims?
The first product is 1mm thick, while the second is only 0.3mm thick. This 0.7mm difference allows you to choose based on the gap size in your hardware. Use the thicker 1mm shim for larger gaps and the thinner 0.3mm version for minimal height changes.
Do these shims come with adhesive for installation?
Both products feature thermal tape for mounting. This adhesive allows you to attach the copper sheets directly to components without additional glue. The 15x15mm version uses thermal tape, and the 20x20mm version offers direct adhesive attachment for secure placement on small ICs or memory.
Which shim is better for cooling small memory chips?
The 20x20mm 0.3mm copper shim is ideal for small electronic cooling, including memory modules. Its precise thin profile fits components that require minimal height increase. The 15x15mm version is also suitable for small chips but is thicker, making it better for filling larger gaps.
Is the material quality different between the two products?
Both shims are made from copper, providing the same thermal conductivity properties. The primary difference lies in their dimensions and thickness. You can expect similar temperature resistance and heat dissipation capabilities from both, with the choice depending on your specific spatial constraints.
What are the exact dimensions of the 0.3mm shim?
The 20x20mm 0.3mm copper shim measures 0.79 inches in width and 0.79 inches in length. This square footprint provides a larger surface area for heat dissipation compared to the 15x15mm option. The thickness is precisely 0.3mm, making it very low profile.
Can I use these shims for CPU socket gaps?
These shims are designed for desktop systems and small chip cooling. While not explicitly labeled for CPU sockets, the 15x15mm 1mm version fits users needing a thicker pad for small chips. The 20x20mm version is better for GPUs and small ICs rather than direct CPU contact.
