Size, Fins, and Weight Comparison

Physical Dimensions

Edge: Tie

The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack measures 40 by 40 by 20 millimeters. This compact form factor fits tight spaces on small components like NEMA17 stepper motors or small IC chips. The Awxlumv 100x100x18mm Aluminum Heatsink is significantly larger at 100 by 100 by 18 millimeters. Its wider base covers more surface area, making it better for larger power devices or MOSFETs. You need to choose the size that matches your component footprint. The smaller unit offers four pieces per pack, while the larger unit is sold individually. Consider your available space carefully before deciding.

Fin Count

Edge: Awxlumv 100x100x18mm Aluminum Heatsink

The Awxlumv 100x100x18mm Aluminum Heatsink features 16 fins. These fins increase the surface area exposed to the air, improving passive heat dissipation. The data for the Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack does not specify the number of fins. However, its 20-millimeter height suggests a moderate fin density suitable for low-power applications. The larger heatsink with 16 fins is likely more effective for higher thermal loads due to its extended surface area. If you are cooling a high-output device, the fin count on the larger model provides a clear advantage in thermal management.

Material Weight

Edge: Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack

Weight impacts how easily you can mount the heatsink and the overall mass of your device. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack weighs 1.45 ounces per unit. This light weight is ideal for delicate components or portable projects. The Awxlumv 100x100x18mm Aluminum Heatsink does not list a specific weight in the provided data. Pure aluminum construction is noted for both, ensuring efficient heat transfer without excessive bulk. The lighter 40mm unit is easier to handle for small-scale electronics, while the larger unit relies on its size rather than mass for performance.

Compatible Devices

Edge: Tie

Compatibility varies between the two options based on their design. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack is listed for IC chips, NEMA17 stepper motors, TEC1-12706 coolers, and LED lights. It is also noted for VRM and 3D printer applications. The Awxlumv 100x100x18mm Aluminum Heatsink is specified for MOSFETs, GPUs, power amplifiers, and routers. If you are building a 3D printer, the smaller unit is the direct choice. For GPU or MOSFET cooling, the larger unit is better suited. Match the compatible device list to your specific electronic component.

Package Quantity

Edge: Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack

The value and utility of the package differ significantly. The Awxlumv 40mm Anodized Aluminum Heatsink 4-Pack includes four identical units. This is useful if you need to cool multiple components, such as several stepper motors on a 3D printer. The Awxlumv 100x100x18mm Aluminum Heatsink comes as a single piece. It does not include screws or thermal paste. If you need multiple cooling units for a single project, the four-pack offers better convenience. For a single large component, the individual unit is sufficient. Plan your quantity needs based on the number of components to cool.

Frequently asked questions

What is the difference in size between the Awxlumv 40mm and 100mm heatsinks?

The 40mm model measures 40 by 40 by 20 millimeters, while the 100mm variant is 100 by 100 by 18 millimeters. The smaller unit is designed for tight spaces around stepper motors or small ICs. The larger sink offers more surface area for components like MOSFETs or GPUs that generate moderate heat.

Are these heatsinks passive or active cooling solutions?

Both are passive cooling solutions. They do not include fans or moving parts. They rely on natural convection and their aluminum construction to dissipate heat. You must ensure your system has adequate airflow or mounting options to make them effective for your specific electronic components.

What material are these Awxlumv heatsinks made from?

Both products are constructed from aluminum. The 40mm model comes in a 4-pack, while the 100mm unit is sold individually. Aluminum provides good thermal conductivity and corrosion resistance, making it suitable for cooling various electronic devices without adding significant weight or bulk to your setup.

Can I use the 40mm heatsink for a GPU?

The 40mm model is best suited for small passive cooling tasks like stepper motors or VRMs. It is too small for typical GPU cooling needs. The 100x100x18mm heatsink is explicitly noted as compatible with GPUs and is better for managing heat from larger components like MOSFETs or integrated circuits.

How much does the 40mm heatsink weigh?

The 40mm Anodized Aluminum Heatsink 4-Pack weighs 1.45 ounces. This lightweight design makes it easy to mount on small components without adding stress. The 100mm model does not list a specific weight in its data, but its larger dimensions suggest it will be heavier than the compact 40mm option.

What does the 40mm heatsink package include?

The 40mm product is sold as a 4-pack. This allows you to cool multiple small components simultaneously, such as several stepper motors or IC chips on a 3D printer. The 100mm heatsink is listed as a single unit, suitable for cooling one larger component like a MOSFET or GPU chip.

Is anodized coating important for these aluminum heatsinks?

Yes, the anodized finish provides corrosion resistance and helps with heat dissipation. It protects the aluminum from environmental damage while maintaining efficient thermal transfer. Both the 40mm and 100mm models feature this treatment, ensuring durability for long-term use in electronic devices where moisture or heat might be present.
