Who it fits
Good fit for
You should consider these shims if you have a desktop GPU or CPU with a localized hot spot. They are suitable for cooling memory modules or northbridge chips that lack dedicated cooling. The adhesive backing makes them easy to install without complex hardware. If you need a cheap, small solution for specific components, this fits your needs. The copper material ensures effective heat dissipation for small areas.
Who should skip it
You should skip this product if you need a complete CPU cooler for the entire processor. These shims do not replace a heatsink or fan assembly. They are also not ideal if you require a warranty or long-term durability beyond the adhesive life. The copper surface may darken over time, which might concern some users. If you need a comprehensive cooling solution, look for a full tower or low-profile cooler instead.
Verdict: These shims offer a simple, spec-driven solution for targeted heat dissipation on small electronic components. They are best for users who need a low-profile thermal aid rather than a full cooling system.
Key specs explained for shims
Material: Copper
Copper is a metal with high thermal conductivity. It moves heat away from hot components quickly. You should compare this to aluminum, which is lighter but less efficient. This material suits users who need rapid heat transfer for small chips or memory modules. It is a standard choice for effective passive cooling in tight spaces.
Dimensions: 20mm x 20mm, 0.3mm thickness
These measurements define the physical footprint and profile of the shim. The 20mm square size fits many small integrated circuits. The 0.3mm thickness adds minimal height. You can compare this to thicker pads that might interfere with nearby parts. This small profile is ideal for filling gaps between a chip and a heatsink without causing clearance issues.
Mounting Type: Thermal Conductive Adhesive Tapes
This method uses a sticky backing to secure the shim. You peel and place it directly onto the component. There are no screws or clips. Compare this to mechanical mounts that require drilling or clamping. Adhesive is best for permanent fixes on small areas. It ensures the shim stays in place during normal computer operation and handling.
Compatible Device: Desktop Computer GPU CPU
The listing specifies use for desktop graphics cards and processors. You can apply these to VRMs, memory, or the CPU core itself. Compare this to laptop-specific pads that have different size constraints. This versatility allows you to target multiple hotspots on a single board. It is a practical solution for broad desktop hardware thermal management.
Design And Build Details
The listing describes these shims as copper sheets with a thermal conductive adhesive backing. Copper is selected for its high thermal conductivity. This material moves heat away from hot components faster than aluminum. You get five sets in the package. Each sheet measures 20mm by 20mm. The thickness is 0.3mm. The listing also notes other thickness options exist, such as 0.5mm or 1mm. This allows you to choose the exact fit for your specific hardware gap.
The adhesive backing simplifies installation. You peel the protective layer and stick the shim directly to the component. This method works well for small electronic devices like memory modules or north and south bridge chips. The listing states the copper can withstand temperatures up to 160 degrees. This durability helps extend the service life of the cooled parts. The weight is listed as 0.35 ounces for the set. This light mass adds negligible stress to fragile components.
According to the listing, the copper surface may darken when exposed to air. This oxidation does not affect the cooling performance. If the appearance matters to you, you can sand the surface with fine sandpaper. The design is purely functional. There are no moving parts or complex mounts. You simply apply the shim where heat dissipation is needed. This straightforward build makes it suitable for desktop GPUs and CPUs that lack dedicated cooling solutions.
Setup And Daily Use Guide
Setting up these shims requires minimal effort. The product includes thermal conductive adhesive tapes on the back. You simply peel the protective layer from the adhesive. Then, you press the copper sheet onto the target component. This method secures the shim without additional tools or mounting hardware. The 0.3mm thickness allows for direct contact with small electronic devices. This includes notebook chips, north and south bridges, and memory modules. You can also apply them to desktop GPU and CPU areas that need extra cooling. The 20mm by 20mm size fits standard small component footprints. In daily use, the copper material transfers heat away from the IC or graphics card. The thermal conductive backing ensures efficient heat flow to the shim. You should note that copper darkens when exposed to air over time. This surface change does not reduce the cooling performance. If the appearance bothers you, you can sand the surface with fine sandpaper to restore shine. The material withstands temperatures up to 160 degrees. This durability supports long-term use in desktop computer systems. The package contains five sets, giving you enough spares for multiple components. These shims are designed for small electronic devices without dedicated cooling functions. They extend the service life of components by managing heat effectively. You do not need complex installation steps. The adhesive backing handles the attachment process. This makes them suitable for users who need a quick thermal solution for specific hotspots on their hardware.
Before you buy these shims
These shims are supplemental aids, not primary coolers. You should not expect them to replace a dedicated CPU air cooler or high-end thermal paste. Their role is to bridge gaps or enhance heat dissipation on specific hotspots like VRMs or chipset areas. Before purchasing, verify that your component surface is flat and clean. The adhesive requires direct contact to function. You may need isopropyl alcohol for surface preparation. Over time, the copper surface may darken when exposed to air. This is normal and does not reduce performance. If aesthetics matter, you can lightly sand the surface. These shims fit best alongside standard cooling setups. They help manage localized heat rather than overall system temperatures. Consider them a precision tool for targeted thermal management. They complement your existing cooling strategy by addressing specific weak points in your desktop computer’s thermal profile.
Check before you buy
- Confirm component surface is flat for adhesive contact
- Verify size fits your specific hotspot area
- Ensure you have cleaning supplies for surface prep
- Understand they supplement, not replace, main coolers
