Others might need a kit with multiple sizes for various components. The alternatives listed here were chosen because their specs overlap with the original. They share the passive cooling method and aluminum construction. You can find options that are thinner, wider, or made from copper. This guide compares these products strictly by their published specifications. You will see how each heatsink compares in dimensions and weight. This helps you pick the right fit for your project without guessing.
Our top pick: ZZHXSM 80mm Black Aluminum Heatsink 2-Pack.
How each alternative compares
Awxlumv 35x35x10mm Black Aluminum Heatsink
The Awxlumv 35x35x10mm heatsink is significantly smaller than the ZZHXSM unit. It measures 35 by 35 by 10mm compared to the original's 80 by 40 by 11mm dimensions. This compact size makes it ideal for tight spaces where the larger ZZHXSM sink cannot fit. It weighs only 0.35 ounces, which is much lighter than the 1.26-ounce ZZHXSM heatsink. Both use black aluminum and adhesive mounting. You should choose this alternative if you are cooling small ICs or stepper motors that require minimal surface area. It sacrifices the larger surface area of the ZZHXSM for extreme space efficiency.
SGTKJSJS 5.9 x 2.91 Black Aluminum Heatsink
The SGTKJSJS 150mm heatsink offers a much longer profile than the ZZHXSM 80mm model. It measures 150 by 74 by 10mm, providing a long, thin shape suitable for flat PCBs. This is quite different from the square footprint of the ZZHXSM sink. It weighs 10.7 ounces, which is heavier than the lightweight ZZHXSM option. Both are passive aluminum heatsinks with adhesive backing. You should pick this alternative if you need to cool low-power components along a longer edge of a board. It gives up the compact square shape of the ZZHXSM for extended linear coverage.
Awxlumv 40x40x20mm Aluminum Heatsink
The Awxlumv 40x40x20mm heatsink is thicker than the ZZHXSM 80mm model. It measures 40 by 40 by 20mm, offering more height for heat dissipation compared to the 11mm height of the ZZHXSM sink. It weighs 3.76 ounces, which is heavier than the 1.26-ounce ZZHXSM unit. Both use black aluminum and adhesive mounting. You should choose this alternative for cooling VRMs or small GPU backplates where vertical space is available. It provides more material for heat spreading than the thin ZZHXSM sink, though it covers a smaller surface area.
Awxlumv 60x40x11mm Aluminum Heatsinks (2-Pack)
The Awxlumv 60x40x11mm heatsink is slightly smaller in length than the ZZHXSM 80mm model. It measures 60 by 40 by 11mm, sharing the same 11mm height but reducing the length from 80mm to 60mm. It weighs 1.84 ounces for the 2-pack, which is comparable to the ZZHXSM weight. Both are passive aluminum heatsinks with thermal tape. You should pick this alternative for tight spaces where the 80mm length of the ZZHXSM is too long. It offers similar cooling performance for low-heat components while saving space along one axis.
Awxlumv 100x45x5mm Thin Aluminum Heatsink
The Awxlumv 100x45x5mm heatsink is much thinner than the ZZHXSM 80mm model. It measures 100 by 45 by 5mm, offering a profile of only 5mm compared to the 11mm height of the ZZHXSM sink. It weighs 3.2 ounces, which is heavier than the single ZZHXSM unit. Both use black aluminum and adhesive mounting. You should choose this alternative if you need a very low-profile solution for tight spaces like LED strips or FPV transmitters. It sacrifices height for a larger surface area in a flatter design.
Easycargo 20-Piece Copper and Aluminum Heatsink Kit
The Easycargo 20-Piece Kit provides a variety of sizes rather than a single large heatsink. It includes copper and aluminum options, whereas the ZZHXSM is exclusively aluminum. The individual pieces in the kit are much smaller than the 80mm ZZHXSM unit. This kit is designed for Raspberry Pi passive cooling, offering multiple small sinks for different components. You should pick this alternative if you need to cool several small chips on a board simultaneously. It gives up the single large surface area of the ZZHXSM for versatile, multi-component coverage.
