Heatsink Specs Compared
build material
The Awxlumv 40mm Anodized Aluminum Heatsink uses anodized aluminum for its construction. This material provides a smooth surface free of scratches and burrs, which helps in efficient heat transfer. The anodization process adds durability and corrosion resistance. In contrast, the Thermal Grizzly Carbonaut is not a solid heatsink block. It is a thermal pad with a carbon-infused matrix. The product data does not list a solid metal base for the Thermal Grizzly item. Instead, it relies on its composite material to bridge gaps between components and heat sinks. Aluminum offers rigid structural support, while the carbon pad offers compressibility.
dimensions
Size matters when fitting cooling solutions into tight spaces. The Awxlumv heatsink measures 40 x 40 x 20mm. This gives it a substantial footprint and height for passive dissipation. The Thermal Grizzly Carbonaut is significantly smaller, measuring 25 x 25 x 0.2mm. This thin profile allows it to fill small gaps on graphics cards or VRMs. The Awxlumv unit is over 100 times thicker than the Thermal Grizzly pad. You must choose based on the physical space available. The larger Awxlumv block requires more clearance, while the thin pad fits where height is restricted.
compatible device
Each product targets different electronic components. The Awxlumv heatsink is listed for passive cooling of IC chips and NEMA17 stepper motors on 3D printers. It is also suitable for TEC1-12706 thermoelectric coolers and power devices like rectifiers. The Thermal Grizzly Carbonaut is specifically noted for compatibility with Nvidia RTX 2080 graphics cards. It is designed to cool memory modules or power phases on that specific GPU. The Awxlumv is versatile for general electronics and motors. The Thermal Grizzly is specialized for high-end GPU memory cooling. Your choice depends on whether you are cooling a motor or a graphics card.
thermal performance
Thermal conductivity determines how fast heat moves. The Thermal Grizzly Carbonaut boasts a thermal conductivity of 62.5 W/m·K. This high value indicates excellent heat spreading capability for a thermal pad. The Awxlumv heatsink data does not list a specific thermal conductivity number. However, aluminum is a known conductive metal. The Awxlumv relies on surface area for passive cooling without a fan. The Thermal Grizzly requires contact with a heat sink to function. The Carbonaut moves heat quickly, but the Awxlumv dissipates it into the air. The Carbonaut has a higher stated conductivity value.
temperature range
Operating temperature limits are crucial for reliability. The Thermal Grizzly Carbonaut has a usable temperature range from -40°F to 330°F (-25°C to 150°C). This wide range ensures performance in extreme environments. The Awxlumv heatsink data does not specify a temperature limit. Aluminum can generally withstand high heat, but the exact limit is unknown from the provided specs. The Thermal Grizzly pad has a clearly defined and broad operational window. This makes it suitable for components that may reach high temperatures. The Awxlumv is likely safe for standard electronics, but the data is less precise.
Choose based on your cooling needs
You need passive cooling for NEMA17 motors
The Awxlumv heatsink is sized at 40 by 40 by 20 millimeters. This volume provides sufficient surface area for passive cooling of stepper motors in 3D printers. The anodized aluminum construction ensures durability. It is designed to handle the thermal load of these specific devices without requiring active fans.
You require high conductivity for GPU memory
The Thermal Grizzly Carbonaut offers a thermal conductivity of 62.5 W/mK. This specification is critical for transferring heat from GPU memory chips efficiently. Its thin profile of 0.2 millimeters fits tight spaces on cards like the Nvidia RTX 2080. The high conductivity ensures rapid heat dissipation from small contact areas.
You are building a custom LED setup
For LED lights and regulator devices, the Awxlumv heatsink provides a robust mounting surface. Its 40 by 40 millimeter base covers common component footprints. The 20 millimeter height adds extra surface area for passive air cooling. This block helps maintain safe operating temperatures for power devices and LED arrays in enclosed spaces.
