You might be looking for easycargo 10 pieces vrm copper alternatives if the standard 9x9x4mm profile does not fit your build. The original Easycargo heatsink offers straightforward passive cooling for VRMs and MOSFETs. It uses pure copper for efficient heat dissipation and includes pre-applied thermal adhesive tape for easy installation. This compact design suits tight spaces where airflow is limited.
However, you may need a different size or a different quantity. Some builders require smaller footprints for miniature drivers or larger surfaces for high-power regulators. Others might prefer shims to fill gaps rather than direct contact cooling. We selected these alternatives because their specifications overlap with the original product. Each option provides copper-based thermal management for similar components. You can compare dimensions, material quality, and mounting methods to find the right fit for your specific hardware constraints.
Our top pick: Easycargo 9mm Copper VRM Heatsinks.
How each alternative compares
Easycargo 6mm Copper Heatsink 10-Pack
This 6x6x5mm copper heatsink swaps the original’s 9x9mm footprint for a tighter 6mm square. It gains a slightly taller 5mm height, which may help in very shallow slots. The 0.24-inch width and length make it ideal for dense VRM arrays where space is tight. You keep the pre-applied thermal adhesive tape for easy installation. Choose this if your board has smaller MOSFETs or driver chips that cannot accommodate the larger 9mm base. It sacrifices surface area for density, fitting more units in the same physical space. This is a budget-friendly option for compact builds.
Easycargo 12mm Copper VRM Heatsink 6-Pack
The 12x12x4mm heatsink offers a larger 12mm square base compared to the original’s 9mm. It maintains the same 4mm height, so clearance remains unchanged. The increased surface area allows for better heat dissipation on hotter VRMs or power delivery components. It includes pre-applied 3M 8810 adhesive tape for secure mounting. Select this alternative if your components run hotter and need more copper mass to spread the heat. You gain cooling performance but require more board space. This is suitable for high-performance setups where the extra footprint is available. It provides a premium passive cooling solution for larger chips.
Easycargo 6x6x3mm Copper Heatsink 10-Pack
This 6x6x3mm heatsink is the lowest profile option in the list. It stands only 3mm tall, compared to the original’s 4mm. The 6mm square base is smaller, reducing the footprint significantly. It uses pre-applied thermal adhesive tape for direct attachment. Pick this if your case or heatsink clearance is extremely limited. You lose some surface area for heat dissipation but gain the ability to fit into very tight spaces. It is best for low-clearance VRMs or small IC chips. The reduced height ensures it will not interfere with nearby components. This is a practical choice for ultra-compact builds where vertical space is the primary constraint.
Easycargo 15x15x0.5mm Copper Shims 20-Pack
These 15x15x0.5mm copper shims are ultra-sflat pads rather than block heatsinks. They are only 0.5mm thick, far thinner than the original’s 4mm height. The 15mm square size provides a larger contact area. They include pre-applied 3M 8810 tape for easy application. Choose these for laptop GPUs or VRAM where clearance is minimal. They are not standalone coolers but work best when paired with a fan or another heatsink. You gain a low-profile thermal bridge for tight spaces. This is ideal for filling gaps or adding thermal mass where a block would not fit. It is a specialized solution for slim laptop or mini-ITX builds.
Easycargo 100-Piece 15mm Copper Shim Kit
This kit contains 100 pure copper shims in 12 different thicknesses. They are flat 15mm squares, not block heatsinks. The variety of thicknesses allows you to fill exact gaps for M.2 SSDs or laptop chips. They do not include adhesive tape, so you must apply thermal paste or pads separately. Use these to adjust clearance between a heatsink and a component. This is best for fine-tuning thermal contact on M.2 SSDs or RAM. You gain precise height adjustment but lose the ready-to-stick convenience of the original. It is a versatile kit for builders who need to solve clearance mismatches rather than add passive cooling blocks.
Easycargo 20mm Copper Pad Shim Kit
This kit includes 20mm copper pads for filling small thermal gaps. The pads are larger than the original’s 9mm base, covering more area. They are designed for height adjustments on VRMs and RAM. You must apply your own thermal interface material. This is useful for builders who need precise spacing for low-profile cooling setups. It fits cases where you need to bridge a gap between a component and a heatsink. You gain flexibility in gap filling but lack the pre-applied adhesive of the original. It is a practical solution for custom thermal setups. Choose this if you need to adjust the distance between components and cooling solutions.
