Comparing Awxlumv Heatsink Sizes
Physical Dimensions
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack measures 40 x 40 x 20mm. This compact size suits tight spaces. The Awxlumv 80mm Aluminum Heatsink is significantly larger at 80 x 80 x 27mm. Its base is wider and taller. You need more surface area for the larger unit. The 40mm model is ideal for small IC chips. The 80mm model fits larger components like routers or amplifiers. Choose based on your available mounting space and component size.
Material Quality
Both units use aluminum for heat dissipation. The Awxlumv 40mm kit uses standard anodized aluminum. It provides a smooth surface without burrs. The Awxlumv 80mm model specifies 6063-T5 aluminum alloy. This alloy offers higher strength and thermal performance. The 80mm unit also features an anodized finish. This ensures durability and corrosion resistance. The 40mm kit does not specify the alloy grade. The 80mm model provides a clearer material specification for your project.
Fin Count
The Awxlumv 80mm Aluminum Heatsink includes 26 fins. This increases the surface area for passive cooling. More fins help dissipate heat from high-power devices. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack does not list a specific fin count in its data. It relies on its 40x40mm base area. The 80mm unit has a larger base and defined fin structure. This design supports better airflow and heat transfer for larger components.
Weight
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack weighs 1.45 ounces per unit. You get four units in the package. The Awxlumv 80mm Aluminum Heatsink weighs 7.41 ounces for a single unit. The 80mm model is heavier due to its larger mass and 26 fins. The 40mm units are very lightweight. This makes them easy to handle for small electronics. The 80mm unit requires a sturdy mounting surface. Weight impacts installation stability for your specific device.
Package Quantity
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack includes four separate units. You can install them on multiple chips or motors. The Awxlumv 80mm Aluminum Heatsink comes as a single unit. If you need to cool multiple components, you must buy more 80mm units. The 40mm kit offers better value for multi-component cooling. It is suitable for cooling several NEMA17 motors or small ICs at once. The 80mm model is for one large component.
Which Awxlumv Heatsink Should You Buy
Users needing multiple small coolers
You need to cool several components at once. This kit includes four 40 x 40 x 20mm anodized aluminum units. Each weighs 1.45 ounces. The compact size fits tight spaces like stepper motors or small ICs. You get multiple identical sinks for a uniform look across your project without buying individual pieces separately.
Those cooling high-power routers or amplifiers
You require maximum surface area for a single high-heat component. This 80 x 80 x 27mm sink features 26 fins and a 6mm base. It weighs nearly 7.4 ounces, providing substantial thermal mass. The larger footprint dissipates heat more effectively for routers, PCH chips, or power modules that generate significant warmth during long operation.
DIYers building compact 3D printer setups
Space is limited on your 3D printer frame. The 40mm dimensions allow you to attach sinks to NEMA17 motors or voltage regulators without interfering with moving parts. The anodized aluminum surface is smooth and burr-free. You can install multiple units on different components to manage heat distribution efficiently in a confined mechanical assembly.
Engineers standardizing on 80mm fan mounts
You plan to add active cooling later. This heatsink is designed to be compatible with most 80mm fans. Its standard 80mm footprint ensures easy mounting. The 6063-T5 aluminum alloy offers stable performance. If you need to upgrade from passive to active cooling, this larger unit provides a robust base that integrates seamlessly with standard fan sizes.

Frequently asked questions
Can I use the 40mm heatsink for a CPU?
No. The Awxlumv 40mm Anodized Aluminum Heatsink is designed for small ICs and stepper motors. It lacks the surface area needed for high-heat CPU applications. Its compact 40 x 40 x 20mm frame is intended for passive cooling of lower-power components like VRMs in 3D printers.
What is the weight difference between the two models?
The 40mm kit weighs 1.45 ounces per unit, while the 80mm heatsink weighs 7.41 ounces. The larger 80 x 80 x 27mm model is significantly heavier due to its increased aluminum mass. This extra weight provides more thermal mass for dissipating heat from routers or PCH chips.
Does the 80mm heatsink come with a fan?
No. Both products rely on passive cooling. The Awxlumv 80mm Aluminum Heatsink uses its large surface area to dissipate heat without moving parts. It is suitable for routers and PCH chips that do not require active airflow to maintain safe operating temperatures.
How many units do I get with the 40mm option?
You receive four units with the Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack. This kit is ideal if you need to cool multiple components simultaneously. Each unit measures 1.57 inches in width and length, making them easy to install on various small electronics.
Is the 40mm heatsink anodized or raw aluminum?
The 40mm model is anodized aluminum. This finish provides better corrosion resistance compared to raw aluminum. The 80mm heatsink is also made of aluminum but is listed as silver. Both materials offer efficient heat dissipation for their respective passive cooling applications.
Which heatsink is better for a 3D printer?
The 40mm kit is better for 3D printers. It is explicitly listed as compatible with 3D printer VRMs. Its compact 40 x 40 x 20mm size fits tight spaces on stepper motors or control boards. The 80mm model is too large for these specific internal components.
