Comparing Heatsink Alternatives
Easycargo 20-Piece Copper and Aluminum Heatsink Kit
The Easycargo 20-Piece Copper and Aluminum Heatsink Kit targets Raspberry Pi owners rather than large external SSDs. While the original 120mm x 40mm heatsink offers a single large surface for high-heat components, this kit provides twenty smaller units in mixed materials. You get copper and aluminum options in various sizes, all using thermal tape for mounting. This bundle is ideal if you need to cool multiple low-power chips on a single board. You sacrifice the massive surface area of the original for versatility. Choose this if your project requires distributed cooling for several small components instead of one large heat sink.
Awxlumv 40mm Aluminum Heatsink 4-Pack
The Awxlumv 40mm Aluminum Heatsink is designed for tight spaces like 3D printer stepper motors. It measures 40mm x 40mm x 11mm, which is significantly smaller than the original 120mm x 40mm x 20mm unit. This compact form factor allows installation where the larger Easycargo model would not fit. Both use pre-applied thermal tape for easy attachment. You trade cooling capacity for size efficiency. If you are cooling a NEMA 17 motor or similar small device, this smaller footprint is more practical. It is not suitable for large NVMe drives that benefit from the original’s extended fin array.
ZZHXSM 80mm Black Aluminum Heatsink 2-Pack
The ZZHXSM 80mm Black Aluminum Heatsink offers a middle ground in size. It measures 80mm x 40mm x 11mm, which is shorter than the original 120mm length but shares the same width. This makes it a good fit for FPV gear or LEDs where space is limited but some surface area is still needed. Like the original, it uses adhesive mounting. You give up some cooling power by reducing the length, but you gain flexibility for narrower enclosures. Choose this alternative if your component generates moderate heat and requires a slimmer profile than the full-sized Easycargo heatsink.
SGTKJSJS 5.9 x 2.91 Black Aluminum Heatsink
The SGTKJSJS 150mm Black Aluminum Heatsink is much larger than the original. It measures 150mm x 74mm x 10mm, providing a significantly wider surface area. This makes it suitable for small PCB components that need extensive heat dissipation. The original is 120mm x 40mm, so the SGTKJSJS unit is both longer and wider. Both use thermal tape for mounting. You gain more cooling potential with this larger footprint but require more physical space. Pick this option if your component generates more heat than the original can handle and you have room for a larger passive cooler.
Awxlumv 40x40x20mm Aluminum Heatsink
The Awxlumv 40x40x20mm Aluminum Heatsink is a compact square unit, unlike the rectangular shape of the original. It measures 40mm x 40mm x 20mm, matching the height of the Easycargo model but with a much smaller footprint. This design is ideal for GPU backplates or 3D printers where square mounting points are common. Both use pre-applied thermal tape. You sacrifice the long fin array of the original for a square profile that fits specific mounting holes. Choose this if your hardware requires a square heatsink rather than a rectangular one, while maintaining similar thickness.
Awxlumv 60x40x11mm Aluminum Heatsinks (2-Pack)
The Awxlumv 60x40x11mm Aluminum Heatsink is half the length of the original 120mm model. It measures 60mm x 40mm x 11mm, making it suitable for low-heat components like VRMs in tight spaces. The original is taller at 20mm, while this alternative is only 11mm high. Both use thermal tape for installation. You get a smaller, lower-profile solution that fits where the original would be too bulky. This is a good choice for cooling LEDs or small voltage regulators. It is not suitable for high-heat devices that need the larger surface area of the original 120mm heatsink.

Frequently asked questions
Can I use these heatsinks for passive CPU cooling?
These units are designed for low-heat components like VRMs, LEDs, or external SSDs. They lack the surface area and mass required for high-power CPUs. You should avoid using them for active processor cooling, as they will not dissipate enough heat to prevent thermal throttling or damage.
Do all the alternatives include thermal tape?
Yes, every listed product features pre-applied thermal tape. This adhesive simplifies installation by allowing you to stick the heatsink directly onto components. You do not need to purchase separate thermal adhesive or paste, which makes setup faster and cleaner for both small electronics and larger passive cooling tasks.
Which option is best for a Raspberry Pi?
The Easycargo 20-Piece Copper and Aluminum Heatsink Kit is the top choice for Raspberry Pi owners. It includes twenty smaller units in mixed materials, providing flexible coverage for various low-power components. This bundle offers a practical solution for keeping single-board computers cool without requiring complex mounting hardware or fans.
Are there heatsinks suitable for 3D printer stepper motors?
The Awxlumv 40mm and 40x40x20mm Aluminum Heatsinks are ideal for 3D printer stepper motors. Their compact dimensions fit tight spaces within printer frames. The pre-applied thermal tape ensures secure attachment to the motor housings, helping to dissipate heat generated during extended printing sessions without adding noise or bulk.
What is the largest heatsink in this list?
The SGTKJSJS 5.9 x 2.91 Black Aluminum Heatsink is the largest unit. It measures 5.9 inches in length and weighs 10.7 ounces. This substantial size provides a large surface area for passive heat dissipation, making it suitable for small PCB components that require reliable cooling without active airflow systems.
Can I mount these heatsinks on GPU backplates?
Yes, the Awxlumv 40x40x20mm Aluminum Heatsink is specifically noted for GPU backplates. Its compact footprint and adhesive backing allow for easy installation on graphics card surfaces. This helps manage heat from VRMs and memory chips, improving overall stability for small passive cooling applications on modern graphics hardware.
Is aluminum the only material available?
No, the Easycargo 20-Piece Kit includes both copper and aluminum units. Copper offers higher thermal conductivity for specific low-power components, while aluminum provides a lightweight alternative. Most other listed heatsinks are aluminum, which balances cost, weight, and sufficient heat dissipation for external SSDs, LEDs, and other passive cooling needs.
Do I need to buy thermal paste separately?
You do not need to buy thermal paste separately for these units. All listed products come with pre-applied thermal tape. This adhesive layer ensures direct contact between the heatsink and the component, eliminating the need for additional pastes or adhesives. This feature simplifies the installation process for quick and effective passive cooling.
