You may also prefer a different brand or a kit with multiple sizes for versatility. The alternatives in this list were chosen because their specifications overlap with the original product. Each option shares key traits like aluminum construction or adhesive mounting, ensuring they serve similar passive cooling roles. This guide compares these options to help you find the right fit based on your exact dimensional and thermal needs.
Our top pick: Awxlumv 100x45x5mm Thin Aluminum Heatsink.
How the alternatives differ
Awxlumv 35x35x10mm Black Aluminum Heatsink
The Awxlumv 35x35x10mm heatsink is significantly smaller than the original 100x45x5mm model. It measures 1.38 by 1.38 by 0.39 inches, compared to the original’s 3.94 by 1.77 by 0.20 inches. This compact footprint suits tight spaces where the larger sink cannot fit. It shares the same black aluminum material and pre-coated thermal tape for easy mounting. However, it offers less surface area for heat dissipation. You should choose this option if you are cooling small power ICs or LEDs that generate minimal heat. It sacrifices cooling capacity for a smaller physical profile, making it ideal for low-power components in confined electronics projects.
ZZHXSM 80mm Black Aluminum Heatsink 2-Pack
The ZZHXSM 80mm heatsink provides a larger surface area than the original Awxlumv model. It measures 3.15 by 1.57 by 0.44 inches, offering more fin density for passive cooling. Like the original, it uses black aluminum and pre-coated thermal tape for simple installation. The increased size allows it to handle slightly higher thermal loads, making it better for 3D printer components or brighter LEDs. You might prefer this alternative if the original sink is too thin for your specific heat output. It gives up the ultra-thin 5mm profile for greater thermal mass. This makes it a solid choice for users needing more cooling power without switching to active fans.
SGTKJSJS 5.9 x 2.91 Black Aluminum Heatsink
The SGTKJSJS 5.9 x 2.91 heatsink is much larger and heavier than the original thin model. It measures 5.9 by 2.91 by 0.39 inches and weighs 10.7 ounces, compared to the original’s 1.55 ounces. This substantial size provides a large footprint for high-heat components like MOSFETs or voltage regulators. It retains the black aluminum construction and thermal tape backing for easy attachment. You should pick this alternative if your components generate significant heat that the thin original sink cannot manage. It sacrifices the low profile and light weight for superior passive cooling capacity. This option is best for power electronics where thermal performance outweighs the need for a minimal footprint.
Awxlumv 40x40x20mm Aluminum Heatsink
The Awxlumv 40x40x20mm heatsink offers a thicker profile than the original 5mm model. It measures 1.57 by 1.57 by 0.79 inches, providing more material for heat absorption. It shares the same black aluminum material and thermal tape features. This increased thickness makes it suitable for GPU backplates or VRMs that require more thermal mass. You might choose this option if you need a compact but deeper sink for specific motherboard components. It gives up the ultra-thin design for greater cooling potential in a small volume. This alternative is ideal for users who need passive cooling for higher-power components in tight spaces where larger sinks will not fit.
Awxlumv 60x40x11mm Aluminum Heatsinks (2-Pack)
The Awxlumv 60x40x11mm heatsink is a compact alternative with a 11mm height, compared to the original’s 5mm. It measures 3.15 by 1.57 by 0.43 inches, offering more surface area than the thin original. It uses the same black aluminum material and pre-coated thermal tape for mounting. This increased height allows for better passive airflow and heat dissipation. You should select this option if you need more cooling capacity than the 5mm model provides but still want a small footprint. It is well-suited for VRMs or LEDs that generate moderate heat. This alternative balances size and thermal performance, making it a practical choice for components that require more than the thinnest available sinks.
Easycargo 20-Piece Copper and Aluminum Heatsink Kit
The Easycargo 20-Piece Kit offers variety rather than a single large heatsink. It includes multiple sizes and materials, including copper and aluminum. The individual pieces are small, with some measuring just 0.55 by 0.55 by 0.28 inches. This kit provides flexibility for cooling Raspberry Pi components or other small electronics. Unlike the original single large sink, this set allows you to match heatsink size to specific chip dimensions. You should choose this option if you need different sizes for various components in a single project. It sacrifices the large continuous surface area of the original for versatility. This is best for users who value having a range of cooling options for different thermal needs.
