Easycargo 100pcs 12 sizes 15mm Alternatives: 6 Similar Picks Compared

Latest update:

As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.

You are looking for easycargo 100pcs 12 sizes 15mm alternatives because the original kit offers broad thickness versatility for precision gap filling. Its C1100 copper build ensures high heat conduction where precise clearance is required. This assortment includes 100 pieces in 12 different thicknesses, ranging from 0.1mm to 2mm. The 15mm x 15mm dimensions make it suitable for small computing hardware like GPUs, RAM, and M.2 SSDs.

However, you might need a different spec, size, or feature. Some projects require wider 20mm pads or specific adhesive backing. Others may need flat heat pipes for directional cooling or graphite-coated surfaces for passive SSD dissipation. The 6 similar picks compared here were chosen because their specifications overlap with the original product. Each alternative targets a specific thermal need, whether that is uniform gap filling, wide component cooling, or targeted heat transfer in tight spaces. You can select the option that best matches your hardware requirements.

Our top pick: Easycargo 100-Piece 15mm Copper Shim Kit.

How alternatives compare to Easycargo

Easycargo 20mm Copper Pad Shim Kit

The Easycargo 20mm Copper Pad Shim Kit replaces the 15mm footprint with a wider 20mm surface area. This change suits components that exceed the original 0.6-inch width. It offers six thickness options instead of twelve, reducing your ability to fine-tune exact gaps. The material remains pure C1100 copper with 401W/mK conductivity. You lose the variety of the 100-piece assortment but gain coverage for broader thermal pads. Pick this if your GPU or VRM heat spreader requires a larger contact surface than the original kit provides.

Easycargo 15x15x0.5mm Copper Shims 20-Pack

The Easycargo 15x15x0.5mm Copper Shims 20-Pack focuses on a single 0.5mm thickness rather than a diverse range. It includes 3M adhesive backing, which the original kit lacks in its standard version. This adhesive simplifies installation on flat surfaces like RAM or SSDs. You sacrifice the ability to adjust for varying gap sizes by sticking to one uniform plate. The copper material and 15mm dimensions match the original. Choose this option when you need a secure, pre-glued solution for a known 0.5mm clearance without searching through multiple thicknesses.

GeeekPi 102-Piece Aluminum and Copper Heatsink Kit

The GeeekPi 102-Piece Aluminum and Copper Heatsink Kit shifts from flat shims to extruded heatsinks. It combines aluminum and copper materials, offering different thermal properties than the pure copper original. The kit includes thermal adhesive for easy mounting on Raspberry Pi boards or small electronics. You give up the low-profile gap-filling nature of the original shims for increased surface area dissipation. This alternative is better for active heat spreading rather than filling tight spaces. Select this if your goal is to cool larger components like VRMs or CPUs where height is not a constraint.

Bopaodao 120mm Flat Copper Heat Pipe

The Bopaodao 120mm Flat Copper Heat Pipe introduces a flat, directional heat transfer method unlike the original static shims. Its 120mm length and 2mm thickness allow it to bridge gaps across longer distances. This design moves heat away from a hot spot to a cooler area, rather than just conducting it through a small pad. You lose the versatility of multiple thicknesses and the compact 15mm footprint. This option is ideal for slim enclosures where traditional shims cannot reach the heatsink. Pick this if your component needs heat redirected laterally rather than vertically.

Bopaodao 5mm x 90mm Copper Heat Pipe

The Bopaodao 5mm x 90mm Copper Heat Pipe offers a compact, fluid-assisted passive cooling solution. Its 90mm length and 5mm diameter provide a different thermal pathway compared to the original flat copper pads. This pipe redirects heat along its axis, useful for tight spaces where flat shims cannot make contact with a sink. You sacrifice the multi-thickness assortment for a specialized heat transport tool. The pure copper material ensures efficient transfer. Choose this alternative when you need to move heat from a small IC chip to a larger area that is out of reach for standard shims.

JOYJOM 2mm Graphite-Coated Copper M.2 Heatsink

The JOYJOM 2mm Graphite-Coated Copper M.2 Heatsink targets M.2 SSDs specifically, unlike the general-purpose original kit. It features a 2mm thickness with a graphite coating to enhance surface radiation. The pure copper base provides steady thermal performance for passive cooling. You lose the variety of sizes and thicknesses, focusing instead on a single 70x20mm form factor. This heatsink is designed to clamp over an SSD rather than fill a gap. Select this if your primary need is cooling an M.2 NVMe drive where the original shims would not fit or function effectively.

Frequently asked questions

Which alternative offers the widest copper shim surface area?

The Easycargo 20mm Copper Pad Shim Kit provides the largest footprint in this list. Its dimensions reach 1.57 inches in width and 6.02 inches in length. This wider surface area suits components that exceed the standard 0.6-inch width of the original 15mm shims. It delivers high thermal conductivity across six thickness options for broader gap filling.

Are there options with adhesive backing for easier installation?

Yes, several alternatives include adhesive backing to simplify installation. The Easycargo 15x15x0.5mm Copper Shims feature thermal tape for straightforward passive chip cooling. The GeeekPi 102-Piece Aluminum and Copper Heatsink Kit also uses thermal adhesive backing. These features help secure components without requiring additional mounting hardware or complex application methods.

What is the best choice for cooling M.2 SSDs?

The JOYJOM 2mm Graphite-Coated Copper M.2 Heatsink is designed specifically for M.2 2280 SSDs. It measures 70x20x2mm and features a graphite coating for enhanced heat dissipation. This passive solution suits users who need reliable cooling for laptops, PS5 consoles, or other systems where space is limited and moving parts are not desired.

Do any alternatives use heat pipes for directional cooling?

The Bopaodao brand offers flat copper heat pipes for directional heat transfer. The 120mm model measures 120mm in length with a width of 5.5mm and thickness of 2mm. The 5mm x 90mm variant provides a compact 90mm span. These pipes serve specialized needs where standard flat shims cannot effectively move heat away from components in tight spaces.

Which kit includes both aluminum and copper materials?

The GeeekPi 102-Piece Aluminum and Copper Heatsink Kit is the only option in this list that combines both materials. It contains an assortment of 17 sizes, primarily aluminum with a small selection of copper units. This mix is ideal for cooling Raspberry Pi boards and small electronics where different thermal properties are beneficial.

How do the dimensions of the 20mm shims compare to the 15mm originals?

The 20mm shims are significantly larger than the original 15mm versions. The original shims measure 0.6 inches by 0.6 inches. The 20mm alternative expands to 1.57 inches in width and 5.12 inches in height. This increase in surface area allows for better heat spreading across wider components like GPUs and VRMs.
