Which one should you choose?
Choose Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack if
- You need a larger surface area for passive cooling on bigger ICs or NEMA17 motors.
- You already have thermal paste on hand and prefer not to use sticky tape.
- You are working on a project where the 40mm footprint fits comfortably without obstruction.
Choose Awxlumv 25mm Small Aluminum Heatsink 6-Pack if
- You are cooling small chips like those on an ASUS ROG Ally or compact PC components.
- You want a quick installation using the pre-applied adhesive tape without mixing glue.
- You need more units for the same total cost and require a lower profile of 10mm.
Verdict: The 40mm heatsink offers more material for heat dissipation, making it suitable for higher thermal loads on stepper motors or larger regulators. The 25mm option is better for tight spaces and provides a convenient, pre-applied tape solution. Choose the larger size for maximum cooling potential and the smaller size for ease of use and compactness.
Size and Mounting Differences
Physical dimensions
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack measures 40 x 40 x 20mm. Each unit weighs 1.45 ounces. The Awxlumv 25mm Small Aluminum Heatsink 6-Pack is much smaller at 25 x 25 x 10mm. Each unit weighs only 0.2 ounces. You need more surface area for higher heat loads. The 40mm model provides that extra volume. It is better for components that generate significant thermal energy. The 25mm model is compact. It fits in tight spaces where the larger heatsink would not fit. Choose the 40mm for capacity and the 25mm for space constraints.
Mounting method
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack does not include adhesive. You must use thermal conductive glue paste for installation. The package contains only the four heatsinks. The Awxlumv 25mm Small Aluminum Heatsink 6-Pack comes with pre-applied thermal conductive adhesive tape. You do not need separate glue. This makes installation faster and cleaner. You simply peel and stick the unit onto the component. The 25mm option is more convenient for quick repairs or projects where messy paste is undesirable. The 40mm requires more effort and materials to secure properly.
Quantity included
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack includes four units. The Awxlumv 25mm Small Aluminum Heatsink 6-Pack includes six units. You get more individual heatsinks with the 25mm option. This is useful if you need to cool multiple small components at once. The 40mm heatsinks are larger and heavier. They might be sufficient for fewer, hotter components. The 25mm heatsinks are lighter. Having six of them allows for distributed cooling across a wider area. Consider your total cooling needs. If you have many small chips, the six-pack offers better value in count.
Compatible devices
Both heatsinks support passive cooling for IC chips, NEMA17 stepper motors, and LED lights. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack is listed for VRM cooling and 3D printers. The Awxlumv 25mm Small Aluminum Heatsink 6-Pack is listed for GPU cooling and the ASUS ROG Ally. The 40mm model has a larger footprint. It may cover VRMs more effectively. The 25mm model is small enough for handheld consoles like the ROG Ally. Choose the 40mm for standard PC VRMs or 3D printer motors. Choose the 25mm for GPUs or portable gaming devices.
Build quality
Both products use anodized aluminum for their construction. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack features a smooth surface without scratches or burrs. The Awxlumv 25mm Small Aluminum Heatsink 6-Pack is also black anodized aluminum. The data does not specify surface finish details for the 25mm model. Both are designed for passive cooling. The anodized layer helps with corrosion resistance and heat dissipation. The 40mm model has a thicker profile. This might offer slightly better structural rigidity. However, both use the same base material. The build quality is comparable for their respective sizes.
Which Awxlumv Heatsink Fits Your Needs
Users needing strong passive cooling for larger components
Choose the 40mm heatsink if you need more surface area for heat dissipation. Its 40 x 40 x 20mm dimensions and 1.45 ounce weight provide a substantial thermal mass. This larger footprint is ideal for passive cooling applications like NEMA17 stepper motors or larger power ICs where maximum heat spread is critical for stability.
Users wanting easy installation with pre-applied adhesive
The 25mm heatsink features pre-applied thermal conductive adhesive tape. This eliminates the need for separate glue, making installation faster and cleaner. Its compact 25 x 25 x 10mm size fits tight spaces like the ASUS ROG Ally or small PC chipsets. You get six units per pack for multiple small components.
Users prioritizing quantity and compact footprint
If you need to cool many small devices, the 6-pack offers better value in quantity. The 0.2 ounce weight per unit keeps the total package light. The 8 x 8 fin structure provides adequate cooling for LED lights or small regulators. Its small 0.98 inch footprint allows for dense component layouts.

Frequently asked questions
Which heatsink is better for NEMA17 stepper motors?
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack is the better choice. It is specifically designed for NEMA17 motors and provides more surface area for passive cooling. Its larger 40 x 40 x 20mm size helps dissipate heat more effectively than the smaller 25mm option for these components.
Does the smaller heatsink come with adhesive backing?
The product description for the Awxlumv 25mm Small Aluminum Heatsink suggests it is a practical solution for users who need a simple, adhesive-backed option. This makes it suitable for small circuit boards or handheld devices where space is limited and easy installation is preferred.
What is the weight difference between the two packs?
The 40mm heatsink units weigh 1.45 ounces each, while the 25mm units weigh 1.27 ounces total for the pack. This significant difference in mass affects thermal capacity. The heavier 40mm unit offers more thermal mass for sustained passive cooling compared to the lighter 25mm alternative.
Can I use the 25mm heatsink on a GPU?
Yes, the Awxlumv 25mm Small Aluminum Heatsink lists GPU as a compatible device. It is intended for small, low-power components where space is tight. Ensure your specific GPU component does not exceed the thermal limits of this smaller 25 x 25 x 10mm unit.
Is thermal paste included with these heatsinks?
The guide notes that you must supply your own thermal paste for the 40mm heatsink. While not explicitly stated for the 25mm model, passive aluminum heatsinks generally require user-applied paste for optimal contact. You should prepare thermal paste before installation for both options.
Which option is suitable for 3D printers?
The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack is explicitly listed as compatible with 3D printers. Its larger dimensions allow it to cool VRMs or other components effectively. The smaller 25mm model is better suited for handheld consoles rather than typical 3D printer electronics.
