Looking Beyond the JIUWU 15x15x0.8mm Copper Heatsink Shims? 6 Alternatives Worth a Look
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for jiuwu heatsink copper pad shims alternatives because the original product has specific limitations. The JIUWU option uses high purity copper in a 15mm x 15mm x 0.8mm size. It works well for laptop GPU and CPU cooling where that exact thickness is required. However, you might need a different size or a different thickness. Some builds require wider pads or thinner spacers. Others may need adhesive backing for easier installation. The JIUWU shims do not include adhesive, which can be a drawback for some users. You might also want more variety in thickness options for filling various gaps. The alternatives in this list were chosen because their specs overlap with the original. They offer similar copper material and compatible device support. You can find options with different dimensions or additional features. This list covers 6 alternatives that address these specific needs. Each option provides a practical solution for thermal management. You can compare the dimensions and material details to find the best fit for your hardware.
Our top pick: JIUWU 15x15x0.8mm Copper Heatsink Shims.
Key differences between alternatives
Uxcell 20mm Pure Copper Thermal Shim
The Uxcell shim increases the surface area to 20mm x 20mm. This wider footprint helps bridge larger gaps between components. It also adds 0.2mm of thickness, bringing the total to 1.0mm. You lose the precise 0.8mm fitment of the JIUWU pad. This option suits builds where the thermal gap is wider than 0.8mm. The larger copper square distributes heat across a broader area. It remains a bare copper pad without adhesive. You must apply your own thermal interface material. This makes it ideal for custom laptop repairs where spacing varies.
Easycargo 15x15x0.5mm Copper Shims 20-Pack
This Easycargo pack offers a thinner 0.5mm profile. The 15mm x 15mm square matches the JIUWU footprint exactly. The key difference is the included thermal tape. You get ready-to-use adhesive backing on each shim. This simplifies installation for VRAM or small chips. The thinner profile fills smaller gaps that the 0.8mm JIUWU pad cannot. You get a bulk quantity for multiple repairs. It works well for laptop and RAM cooling. The trade-off is less vertical height for heat dissipation. Choose this if you need precise, low-profile spacers with easy application.
Easycargo 100-Piece 15mm Copper Shim Kit
The Easycargo 100-piece kit provides twelve different thickness options. All shims remain 15mm x 15mm. This variety allows you to match exact gap heights without stacking. The JIUWU product offers only one fixed 0.8mm size. This kit gives you manual control over thermal interface placement. It includes pure copper shims for various components like PS5 and M.2 SSDs. You do not get pre-applied adhesive. You must use your own thermal tape or paste. This option is best for technicians who need flexibility in gap filling for diverse hardware.
Bopaodao 120mm Flat Copper Heat Pipe
The Bopaodao flat heat pipe uses a different cooling method. It is a 120mm long copper pipe with a 5.5mm width and 2mm thickness. This is not a shim for gap filling. It extends heat dissipation surface area passively. The JIUWU shim conducts heat through direct contact. This pipe moves heat away from hot spots to cooler areas. It suits builders who need to extend cooling reach. The dimensions allow for custom routing around components. You use this for targeted thermal management rather than simple spacing. It is a passive conductor for GPUs or laptops needing extended surface area.
Bopaodao 5mm x 90mm Copper Heat Pipe
This Bopaodao heat pipe is a 5mm diameter cylinder. It is 90mm long. Like the previous pipe, it moves heat passively. It targets small hot spots effectively. The JIUWU shim is a flat pad for direct contact. This pipe transfers heat from a chip to a larger heatsink. It suits tight spaces where flat shims cannot reach. You use it for VRAM or CPU backplate cooling. The cylindrical shape allows heat to travel along its length. It is not a spacer. Choose this for active heat transport in confined areas rather than simple gap filling.
PATIKIL 15x15x0.3mm Copper Heatsink Shims
The PATIKIL shim is the thinnest option at 0.3mm. It keeps the 15mm x 15mm square size. This thickness fills very small gaps that the 0.8mm JIUWU pad cannot. It is suitable for desktop and laptop use. The shim is pure copper for good conductivity. You must apply your own adhesive. It lacks the thickness needed for larger gaps. This option is best for precision gap filling where minimal height is required. It works well between chips and cooling modules. Choose this if your thermal interface requires a very low profile spacer.

Frequently asked questions
Are these copper shims adhesive-backed?
Most options in this list are bare copper without adhesive. The JIUWU and Uxcell shims require you to apply your own thermal tape or paste. However, the Easycargo 15x15x0.5mm pack includes ready-to-use thermal tape. This saves time if you need quick installation for laptop repairs or VRAM cooling without sourcing extra materials.
What is the best shim for desktop PCs?
The PATIKIL 15x15x0.3mm Copper Heatsink Shims are listed as the best option for desktop systems. They provide a very thin 0.3mm profile, which is ideal for filling small gaps between chips and cooling modules. This precise fitment helps maintain proper clearance while ensuring efficient heat transfer from the component to the heatsink.
Can I use these shims for VRAM cooling?
Yes, several products are explicitly compatible with RAM modules. The Easycargo 15x15x0.5mm pack and the 100-piece kit are both suitable for VRAM applications. Their thin profiles and copper material help bridge the gap between memory chips and the heatsink, improving thermal conductivity for graphics cards and laptop memory components.
Is there a thicker option than the JIUWU 0.8mm shim?
The Uxcell 20mm Pure Copper Thermal Shim offers a thickness of 1.0mm. This is 0.2mm thicker than the JIUWU option. It also features a larger 20mm x 20mm footprint, making it better for wider thermal gaps. This extra thickness and surface area help bridge larger distances between components.
Do these alternatives include copper heat pipes?
The Bopaodao products are flat copper heat pipes rather than simple shims. The 120mm and 5mm variants are designed to extend heatsink surface area. They provide targeted cooling for small hot spots or VRAM. These passive conductors allow you to customize the heat dissipation path for specific laptop or desktop components.
Which shim is best for bulk repairs?
The Easycargo 15x15x0.5mm Copper Shims 20-Pack is the best budget choice for bulk work. It provides multiple units for repairing laptops or VRAM modules. The included thermal tape simplifies the process. This pack is efficient if you need many small spacers for repeated repairs or large-scale component cooling projects.
