This patikil 15x15x0 4mm copper heatsink shims review looks at a simple thermal accessory. You get six copper pads designed to bridge gaps between heat sources and cooling modules. The defining specs are the 15x15mm footprint and the 0.4mm thickness. Copper offers high thermal conductivity, helping move heat away from hotspots on GPUs, CPUs, or chipsets. These shims fill empty space to improve contact. They are not a standalone cooler but a spacer to enhance existing thermal paths. The goal is to reduce overheating risks by ensuring better physical connection between components and their heatsinks.
What stands out
- Pure copper material for reliable thermal and electrical conductivity
- Precise 15x15x0.4mm dimensions to fit specific gap sizes
- Smooth surface with no burrs for consistent contact
- Pack of six shims for multiple component cooling
Who it fits
Good fit for
You should consider these shims if you have a GPU or CPU cooler that sits slightly too high above the chip. The 0.4mm thickness fills small gaps, improving heat transfer. Desktop users with custom loops or specific cooler mounts may find them useful for ICs or northbridges. If your current setup has poor contact due to height mismatches, these copper pads can help bridge that distance. They are ideal for small electronic devices needing extra thermal mass in tight spaces.
Who should skip it
You should look elsewhere if you need a standalone cooling solution. These shims do not generate cooling; they only improve contact. If your gap is larger than 0.4mm, this size will not help. You might need thicker options from the available variations. Also, skip this if you require adhesive backing, as the listing notes accessories are not included. You must apply your own adhesive. If you cannot clean surfaces with alcohol first, proper installation may be difficult, leading to poor thermal performance.
Verdict: These shims are a practical, spec-driven solution for filling small thermal gaps. They work well when you need to bridge a precise 0.4mm space with conductive copper.
Key specs explained
Material: Copper
Copper provides excellent thermal conductivity, moving heat away from hot components faster than aluminum or steel. You should use these shims to bridge gaps between a chip and a heatsink. This ensures better contact and lowers temperatures. When shopping for thermal paste or air coolers, remember that copper surfaces help spread heat evenly across the base.
Dimensions: 15x15x0.4mm
This size defines the footprint and thickness of each shim. The 15x15mm area covers small chips or memory modules effectively. The 0.4mm thickness fills specific gaps between hardware and cooling solutions. You need this exact measurement to ensure the shim fits your setup without interfering with fans. Compare this to standard thermal pad thicknesses when selecting accessories.
Width: 0.16 inches
This measurement confirms the shim thickness in imperial units. It helps you verify compatibility with existing hardware clearances. A 0.16-inch gap is small but significant for tight builds. You should check your component heights to ensure this shim fits. This spec is useful if your manual lists dimensions in inches rather than millimeters.
Length: 5.91 inches
This value represents the length of the shim in inches. It corresponds to the 15mm metric dimension. You can use this to visualize the surface area available for heat transfer. Ensure your cooling module covers this area for optimal performance. This data point helps you compare shim sizes against other thermal accessories in your build.
Design and Build Details
According to the listing, the PATIKIL shims are constructed from pure copper. This material choice provides high thermal and electrical conductivity. You get a smooth, bright surface with no burrs on the edges. The manufacturing process aims for a clean finish that ensures reliable contact with your hardware. Copper transfers heat efficiently, which is critical for bridging gaps between components. This construction supports long-term use without rapid degradation, provided you handle them with care.
The physical dimensions are 15x15x0.4mm. This translates to a 5.91x5.91x0.16 inch footprint. The 0.4mm thickness is the primary variable here. The listing notes that other thickness options exist, such as 0.1mm, 0.5mm, or 1.2mm variants. You must select the shim that matches the exact gap in your build. The square shape allows for straightforward placement over chips, GPUs, or CPU heat spreaders. The size is compact enough for small electronic devices, laptops, and desktop motherboards.
The package includes six pieces. You can use them to fill voids between graphics cards and cooling modules. This reduces the risk of overheating and prevents performance degradation. The listing advises cleaning the surface with alcohol before application. You then stick the shim to the hardware needing cooling. These shims are suitable for cooling IC chipsets, north and south bridges, and memory modules. They are designed for desktop systems and laptops where direct contact is limited by physical spacing.
Setup And Daily Use Guide
Installation requires careful preparation. You must clean the shim surface with alcohol and a microfiber cloth before applying it. This step removes oils and debris that could block heat transfer. The listing notes that adhesive is not included. You need to source your own bonding material to secure the shim to the target component. Once cleaned, you stick the shim to any hardware needing extra cooling. The 0.4mm thickness allows it to fill small gaps between chips and heatsinks. This reduces the distance heat must travel, improving contact efficiency.
These shims are compatible with GPUs, CPUs, IC chipsets, laptops, and desktop systems. They also work on memory modules and north or south bridges. Use them on components that lack built-in heat dissipation. The copper material conducts heat effectively, helping to lower operating temperatures. This prevents performance degradation caused by overheating. The 15x15mm footprint fits most standard chip sizes. If your component is larger, you may need to combine multiple shims or choose a different size variant.
Daily use involves leaving the shim in place. It acts as a permanent thermal bridge. Copper does not degrade quickly, so the shim maintains its shape and conductivity over time. Ensure the shim remains flat and fully bonded. Any air pockets will reduce effectiveness. Regularly check for dust accumulation on the shim surface, as dust can insulate heat. Clean gently with compressed air if needed. The shim requires no power or software configuration. It works passively alongside your existing cooling solution.
Before You Buy These Shims
You need to verify your gap size before purchasing. The 0.4mm thickness is specific. If your heatsink sits too high, these shims will not help. You might need a thicker option from the available variations. Check if your board has space for the 15x15mm footprint. You must also buy thermal adhesive separately. The listing does not include it. Clean the surface with alcohol before application. Dust buildup can reduce effectiveness over time. Wipe the copper with a dry cloth occasionally. These shims complement air coolers by filling voids. They do not replace a heatsink. Use them alongside your existing cooling solution. They suit GPUs and chipsets that lack direct contact. Ensure your component generates enough heat to justify the shim. This product fits into a broader cooling strategy. It addresses specific spacing issues rather than providing primary cooling. Review other thermal paste options for better contact on flat surfaces. This shim is for gap bridging only.
Check before you buy
- Measure the exact gap between your chip and heatsink.
- Confirm the 15x15mm footprint fits your component layout.
- Purchase thermal adhesive separately as it is not included.
- Check if a different thickness option suits your needs.
- Ensure your GPU or chipset lacks direct heatsink contact.
