As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are looking for awxlumv heatsink kit 100 x alternatives, you likely need passive cooling for low-power components. The original Awxlumv 100x50mm Thin Aluminum Heatsink offers a flat, adhesive-backed design for tight spaces like stepper motors. Its 100x50x4mm dimensions and anodized aluminum material make it suitable for specific compact electronics. However, you might prefer a different size, material mix, or mounting style for your project.
The alternatives listed here were chosen because their specifications overlap with the original product. Each option provides passive cooling via thermal tape, similar to the Awxlumv unit. You can find variations in dimensions, such as the smaller Easycargo pads or the larger ZZHXSM sink. Some kits include copper for higher thermal conductivity, while others offer black anodized finishes. These specs allow you to match the heatsink to your exact component requirements without guessing. The list covers various brands and sizes to help you find the right fit.
How these alternatives compare
Easycargo 20-Piece Copper and Aluminum Heatsink Kit
The Easycargo 20-Piece Kit shifts focus from single large sinks to a variety of small pads for Raspberry Pi boards. While the Awxlumv uses a large 100x50mm footprint, these pads are tiny at 0.55 inches square. You get a mix of copper and aluminum materials, which conduct heat differently than the uniform anodized aluminum of the original. The height is 0.28 inches, slightly taller than the Awxlumv’s 0.16-inch profile. This kit suits users with multiple small chips needing individual cooling rather than one large surface. It sacrifices the broad coverage of the 100x50mm design for versatility across different board components.
Awxlumv 40mm Aluminum Heatsink 4-Pack
This Awxlumv 40mm heatsink offers a square 40x40mm footprint instead of the original’s rectangular shape. It is thicker at 11mm high compared to the 4mm height of the 100x50mm model. The increased height provides more surface area for passive dissipation, which helps with stepper motors that generate moderate heat. It uses the same adhesive mounting method, so installation is similar. However, the smaller base area means it covers less space. You should choose this if your component fits a square pad better or if you need more vertical surface area for airflow than the thin original provides.
ZZHXSM 80mm Black Aluminum Heatsink 2-Pack
The ZZHXSM 80mm heatsink is a black aluminum unit with a 80x40mm base. It is significantly thicker than the Awxlumv, standing 11mm high versus 4mm. This extra height increases the surface area for passive cooling, making it better for LEDs or FPV gear that need more dissipation capacity. The black finish may absorb slightly more ambient heat, but the aluminum core remains the same. It uses thermal tape for mounting, just like the original. If you need a taller sink for better passive airflow in a compact FPV setup, this is a practical upgrade over the very thin Awxlumv design.
SGTKJSJS 5.9 x 2.91 Black Aluminum Heatsink
The SGTKJSJS 150x74mm heatsink is much larger than the Awxlumv 100x50mm model. Its base covers a wider area, which helps spread heat from small power components more effectively. It is also thicker at 10mm high, offering more material for thermal mass and surface area. The black aluminum construction matches the ZZHXSM style. It uses pre-applied thermal tape for easy installation. You should pick this if your component is larger than the Awxlumv’s footprint or if you need a heavier sink for better thermal capacity. It is less suitable for extremely tight spaces where the thin original fits better.
Awxlumv 40x40x20mm Aluminum Heatsink
This Awxlumv 40x40x20mm heatsink is a square, black aluminum unit. It is much thicker than the original, at 20mm high compared to 4mm. The square base is smaller in total area than the 100x50mm rectangle. It uses thermal tape for mounting, ensuring similar ease of installation. The increased height provides more surface area for passive cooling, which is useful for GPU backplates or 3D printer motors. If you need a compact but taller sink for enclosed spaces, this offers better dissipation than the thin original. It trades the large surface area of the 100x50mm model for greater height and a square form factor.
Easycargo 120mm x 40mm Aluminum Heatsink 2-Pack
The Easycargo 120x40mm heatsink is a long, black aluminum unit designed for external SSDs and NVMe drives. It is much longer than the Awxlumv, at 120mm versus 100mm, and thicker at 20mm high. This shape suits the long form factor of M.2 drives better than the square-ish Awxlumv. It uses pre-applied thermal tape for mounting. The black finish and aluminum material are standard for passive cooling. If you are cooling an NVMe drive, this shape is more appropriate than the 100x50mm model. It offers more surface area and a better fit for linear components compared to the original’s compact rectangular design.
