Comparing Awxlumv Heatsink Sizes
Physical dimensions
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack measures 40 x 40 x 20mm. This compact size fits small IC chips and NEMA17 stepper motors on 3D printers. In contrast, the Awxlumv 150mm Aluminum Heatsink is significantly larger at 60 x 150 x 25mm. You get a much wider surface area for heat dissipation. The larger model is better for high-power LED lights or CPU MOSFETs. The smaller unit is designed for tight spaces where airflow is limited. Choose the 40mm model for precision components and the 150mm model for broader heat spreading needs on larger circuits.
Material finish
Both heatsinks rely on aluminum for thermal conductivity. The 40mm model specifies an anodized aluminum finish. Anodizing adds a protective layer that resists corrosion and wear. The 150mm model is described simply as silver aluminum. It lacks the specific anodized finish mention in the provided data. This means the 40mm unit may offer better long-term surface durability against oxidation. However, both materials provide passive cooling without active fans. The anodized coating on the smaller heatsink is a distinct practical advantage for longevity in humid environments.
Compatible device
The 40mm heatsink targets specific small components like VRMs, 3D printer stepper motors, and TEC1-12706 Peltier coolers. It is also suitable for 50 amp bridge rectifiers and Chromecast devices. The 150mm heatsink is designed for high-power household LED lights, fish tank LEDs, and general IC circuit boards. It explicitly mentions suitability for CPUs and routing heat conduction. If you are cooling a high-power LED strip or a CPU MOS, the 150mm model is the correct choice. The 40mm model is strictly for smaller electronic modules.
Weight and mass
The 40mm heatsink weighs 1.45 ounces per unit. You receive four of them in the package. The 150mm heatsink weighs 147 grams, which is approximately 5.19 ounces. This single unit is substantially heavier than one of the smaller heatsinks. The increased mass helps absorb and dissipate more heat energy. The 150mm model provides more thermal mass for sustained passive cooling. The 40mm units are lightweight and easy to mount on delicate components. Heavier mass generally aids in stability and heat capacity for larger loads.
Fin count
The 150mm heatsink features 24 fins. This design increases the surface area exposed to air for better passive cooling. The 40mm heatsink data does not specify the exact fin count. It describes the substrate as thick and smooth. Without explicit fin details for the 40mm model, we cannot directly compare the density of the cooling structures. However, the 150mm model explicitly lists its fin count, indicating a structured approach to surface area maximization. The 24 fins on the larger unit are a clear specification for heat exchange efficiency.
Choose your heatsink size
You need cooling for small stepper motors
The 40mm heatsink measures 40 x 40 x 20mm. This compact size fits NEMA17 stepper motors on 3D printers like the Ender 3. You get four units in the kit. The anodized aluminum surface helps with passive cooling for these specific small components without taking up much space.
You are cooling high power LED lights
This larger heatsink measures 60 x 150 x 25mm. It is specifically designed for high power household LED lights or fish tank LED devices. The 6063 aluminum material offers strong heat conductivity. Its large surface area dissipates heat effectively to protect components and prolong the device service life.
You need a single large heatsink for CPUs
The 150mm model is suitable for IC circuit boards, motherboards, and CPUs. Its dimensions of 60 x 150 x 25mm provide ample surface area for routing heat. You receive one silver aluminum heatsink. The size allows for effective passive cooling on larger electronic modules where the small 40mm unit would be insufficient.

Frequently asked questions
Is the Awxlumv 40mm heatsink anodized?
Yes, the first model is anodized. This finish helps protect the aluminum surface from corrosion and minor scratches. The larger 150mm version is described only as silver aluminum, with no mention of an anodized coating in the provided specifications.
How many heatsinks come in the 40mm pack?
The smaller kit includes four units. You receive a four-pack of the 40x40x20mm heatsinks. This allows you to cool multiple small components, such as several stepper motors or VRM sections, simultaneously without buying separate units.
Can the 150mm heatsink fit a standard PC fan?
No, the dimensions do not support standard fans. The 150mm model measures 60x150x25mm. Standard PC fans are typically 120mm or 140mm square. This heatsink is designed for passive cooling of large LED or IC boards, not for active fan mounting.
What is the weight difference between the two models?
The 150mm unit is significantly heavier. The single 150mm heatsink weighs 5.19 ounces. The entire 40mm four-pack weighs 1.45 ounces. The larger model provides more aluminum mass for heat dissipation, which adds to its overall weight compared to the compact kit.
Is the 40mm heatsink suitable for VRM cooling?
Yes, it is listed as compatible with VRMs. The compact 40x40x20mm size fits well on voltage regulator modules. It provides passive cooling for low-heat components, making it a practical choice for motherboard VRM thermal management in small form factor builds.
Does the 150mm heatsink include any mounting hardware?
The provided data does not list mounting hardware. The specifications only detail the material, dimensions, and color. You may need to source your own thermal adhesive or screws depending on your specific installation requirements for high-power LEDs or IC boards.
