If you need easycargo 6mm copper heatsink 6x6x5mm alternatives, this list helps you compare options based on published specifications. The original model uses copper and includes pre-applied 3M 8810 adhesive tape. Its compact 6mm x 6mm x 5mm size fits tight spaces. Some buyers might want a different footprint or height. Others may prefer a larger surface area for moderate heat dissipation. The alternatives were chosen because their specs overlap with the original product. This ensures you find compatible parts without guessing. You can explore larger shims or thinner profiles. Each option serves a specific thermal need. We focus strictly on dimensions, material, and mounting type. This approach helps you select the right part for your build. The following sections break down each alternative's key features. You will see how each size compares to the 6mm standard. This guide covers passive cooling solutions only. No active fans or complex mounts are included here.
Comparing heatsink dimensions and fit
Easycargo 9mm Copper VRM Heatsinks
The Easycargo 9mm Copper VRM Heatsink measures 0.35 by 0.35 by 0.16 inches. It offers a larger footprint than the 6mm original, providing more surface area for heat dissipation. The height is slightly lower at 0.16 inches, which helps in very tight spaces. Like the original, it uses copper and includes pre-applied adhesive tape. You should choose this if you need better thermal performance for VRMs or MOSFETs but have a bit more room. The wider base covers more area, improving passive cooling efficiency for components that generate moderate heat.
Easycargo 12mm Copper VRM Heatsink 6-Pack
This 12mm copper heatsink measures 0.47 by 0.47 by 0.16 inches. It is significantly larger than the 6mm original, offering a much greater surface area for passive cooling. The height remains low at 0.16 inches, maintaining compatibility with low-profile builds. It uses copper and includes pre-applied adhesive tape. Pick this option if you are cooling components that produce more heat than the small 6mm block can handle. The larger footprint allows for better airflow contact. It is ideal for moderate heat dissipation on small VRM or GPU chips where space permits a bigger cooler.
Easycargo 6x6x3mm Copper Heatsink 10-Pack
The 6x6x3mm copper heatsink measures 0.24 by 0.24 by 0.12 inches. It shares the same width and length as the original but is thinner. The reduced height of 0.12 inches makes it suitable for extremely tight clearances. It uses copper and includes pre-applied adhesive tape. Choose this if you need passive cooling for small ICs in very confined spaces where even the 5mm height of the original is too tall. It sacrifices some surface area for a lower profile. This is a practical choice for minimal footprint applications where space is the primary constraint.
Easycargo 15x15x0.5mm Copper Shims 20-Pack
The 15x15x0.5mm copper shims measure 0.59 by 0.59 inches with a thickness of 0.02 inches. They are flat shims rather than block heatsinks. They use copper and include adhesive backing. These are best for targeted cooling on small laptop components like VRAM or chipsets. You should pick these if you need precise coverage on flat surfaces rather than a protruding block. They do not offer the same height for airflow as the 6mm heatsink. This option is ideal for filling specific gaps on laptop motherboards where a block shape would not fit.
Easycargo 100-Piece 15mm Copper Shim Kit
The 100-piece 15mm copper shim kit measures 0.6 by 0.6 inches. These are flat copper pads without specified thickness in the data. They are designed for filling thermal gaps on M.2 SSDs and laptop GPUs. They use copper material. This kit is suitable for builders who need to optimize contact pressure without adding bulk. It differs from the original block heatsink by being a gap filler rather than a standalone cooler. Choose this if you need to bridge gaps between components and heatsinks. It is ideal for fine-tuning cooling on compact devices like laptops and PS5s where precise height adjustment is required.
Easycargo 20mm Copper Pad Shim Kit
The 20mm copper pad shim kit measures 1.57 by 6.02 inches with a height of 5.12 inches. These are large copper pads for filling small thermal gaps in compact builds. They use copper material. This kit provides precise height adjustments for VRMs or SSDs without adding bulk. It differs significantly from the small 6mm block heatsink in size and form factor. You should pick this if you need to cover larger areas or fill substantial gaps in your build. It is a practical solution for adjusting thermal contact in space-constrained environments where standard heatsinks cannot fit.

Frequently asked questions
Which Easycargo heatsink has the largest footprint for better heat dissipation?
The Easycargo 12mm Copper VRM Heatsink 6-Pack offers the largest footprint among the block-style options. Its base measures 0.47 by 0.47 inches. This larger surface area helps dissipate moderate heat from small VRM or GPU chips more effectively than the smaller 6mm or 9mm variants.
Are all these heatsinks compatible with GPU and VRM components?
Most options in this list are explicitly rated for GPU and VRM use. The Easycargo 15mm Copper Shims 20-Pack also lists compatibility with Laptop and RAM components. The 100-Piece 15mm Copper Shim Kit expands this further to include PS5 and M.2 SSD applications.
What is the height difference between the 6mm and 9mm heatsinks?
The standard 6mm heatsink stands 0.19 inches tall. The 9mm VRM variant is slightly shorter at 0.16 inches. This lower profile can be beneficial in tight spaces where vertical clearance is limited, even though the 9mm model has a wider base.
Do the copper shims include pre-applied thermal tape?
The 15mm Copper Shims 20-Pack and the 6mm Heatsink 10-Pack both list Thermal Tape as a feature. This means the adhesive is already applied to the back, saving installation time. Other shim kits, like the 100-Piece or 20mm kits, do not list this feature in their specs.
Which option is best for filling gaps on M.2 SSDs?
The Easycargo 100-Piece 15mm Copper Shim Kit is specifically highlighted for this use. It provides precise thermal gap filling for M.2 SSDs and small components. This helps optimize contact pressure without adding bulk, making it ideal for fine-tuning cooling on compact devices like laptops and PS5s.
How thick is the thinnest heatsink option available?
The Easycargo 6x6x3mm Copper Heatsink 10-Pack is the thinnest block-style option. It measures only 0.12 inches in height. This compact size fits users who need passive cooling for small ICs or VRMs in extremely tight spaces where other heatsinks would not fit.
What are the dimensions of the 20mm Copper Pad Shim Kit?
The 20mm Copper Pad Shim Kit has a width of 1.57 inches and a length of 6.02 inches. It is designed for filling small thermal gaps in compact builds. This kit suits users who need precise height adjustments for VRMs or SSDs without adding significant bulk.
