Who it fits
Good fit for
You should consider this option if you are working on laptop repairs or custom GPU modifications. The thin 1.0mm profile is ideal for filling small gaps between chips and heat spreaders. If your project involves development boards or compact PCs with limited clearance, these pads provide a straightforward thermal bridge. The five-pack allows you to treat multiple components at once. It suits builders who need a reliable, passive thermal pad that relies on material properties rather than active fans.
Who should skip it
You should look elsewhere if you need a large surface area for high-end desktop CPUs. These pads are too small to cover standard processor dies effectively. If you require a complete cooling solution with a fan or vapor chamber, this shim is only a component, not a full cooler. Users needing substantial airflow or advanced heat dissipation for overclocked parts will find this insufficient. It is strictly a gap-filler, not a primary cooling device for high-TDP processors.
Verdict: This is a practical thermal shim for filling small gaps in compact builds. It works well as a supplementary cooling aid rather than a primary heatsink.
Key specs explained
Material: Copper
Pure copper offers high thermal conductivity. This material transfers heat quickly from the component to the cooling surface. You benefit from faster heat removal compared to aluminum pads. When shopping for thermal paste or air coolers, look for copper base plates for similar efficiency. This shim acts as a conductive bridge in tight gaps.
Dimensions: 0.79 x 0.79 x 1.0mm
The shim measures 0.79 inches by 0.79 inches with a 1.0mm thickness. This compact size fits into small spaces where larger coolers cannot go. It serves as a gap filler for laptops or GPUs. Compare this to standard heatsink footprints. You need precise measurements to ensure proper contact between the heat source and the sink.
Weight: 2.82 ounces
The package weighs 2.82 ounces for five pieces. This is very light, so it adds negligible stress to your hardware. You can use multiple units without worrying about structural load. Unlike heavy air coolers, these pads do not require mounting brackets. The low weight makes them ideal for portable devices like laptops.
Quantity: 5 Pieces
You receive five identical copper pads in one package. This allows you to cool multiple components or replace units as needed. You can distribute them across a laptop motherboard or GPU. This bulk option is cost-effective for builders. When buying thermal paste, you often get a single tube; here you get reusable physical spacers.
Build Quality and Dimensions
The listing specifies that these shims are made from pure copper. Copper provides high thermal conductivity, which helps move heat away from components faster than many other metals. You get efficient heat dissipation for tight spaces. The material choice matters when you need to bridge a small gap between a hot chip and a cooler surface. This design helps lower CPU or GPU temperatures in compact builds.
According to the listing, each shim measures 0.79 inches by 0.79 inches. The thickness is 1.0mm, which equals 0.04 inches. This compact size makes the pad suitable for small spaces on laptops or development boards. You can use it as a gap filler to ensure better contact between parts. The small footprint allows it to fit where larger heatsinks cannot.
The package includes five pieces, with a total net weight of 19 grams or 0.7 ounces. The lightweight nature means you can install multiple units without adding significant mass. You can apply these pads to cool GPUs, laptops, or other electronic devices. The simple flat design requires no tools or complex mounting. You just place the shim where thermal contact is needed. This straightforward build focuses on function over form, making it a practical choice for specific thermal management tasks.
Setup And Everyday Use
Installation is straightforward because these are passive copper pads. You place them directly between a heat source and a cooling surface. The 1.0mm thickness allows them to bridge small gaps effectively. This setup works well for laptops and GPU modules where space is tight. The compact 20mm by 20mm footprint fits into areas where larger heatsinks cannot go. You do not need complex mounting hardware. Simply position the pad to ensure full contact with both surfaces. The lightweight design, weighing only 19 grams for the full pack, means you can handle multiple units without adding significant mass to your device. Daily use involves relying on the copper’s high thermal conductivity to manage temperatures. The material helps lower CPU and GPU temperatures by efficiently moving heat away from critical components. This can help solve thermal issues that cause frequent crashes or instability. Because the pads are pure copper, they maintain their conductive properties over time. They are suitable for cooling development boards and computer components that generate heat in confined spaces. The package includes five pieces, which provides ample supply for multiple devices or backup replacements. You get consistent cooling performance as long as the gap between components matches the shim’s thickness. This solution is ideal for users who need a simple, spec-driven thermal interface without active fans or complex assembly.
Before You Buy This Copper Shim
You should verify that your target component has a flat surface area matching the 0.79-inch dimensions. These shims act as thermal bridges, so ensure the gap between the heat source and the cooler is approximately 1.0mm. If the gap is larger, you may need additional thermal paste or a different shim thickness to maintain contact. Pair this copper pad with a high-quality thermal interface material for best results. Keep the copper surfaces clean and free of oxidation before installation. This product complements traditional air coolers by addressing specific thermal bottlenecks in compact builds. It fits well alongside standard thermal paste applications where space is limited. Check compatibility with your GPU or laptop motherboard before purchasing. The lightweight design makes it easy to handle during assembly. Ensure your cooling solution can effectively dissipate the heat transferred by the copper.
Check before you buy
- Verify the 0.79-inch surface area matches your component
- Confirm the 1.0mm gap thickness is suitable for your setup
- Check compatibility with your specific GPU or laptop model
- Ensure you have high-quality thermal paste for installation
