- You want faster thermal conductivity provided by pure copper over aluminum.
- You need a complete installation kit with pads and mounting bands included.
Verdict: The Awxlumv heatsink is the better choice for general electronics cooling where you need volume and a taller profile. The JOYJOM heatsink is the correct solution for M.2 SSDs due to its specific dimensions and included thermal pad. Select based on the device you are actually trying to cool.
Awxlumv and JOYJOM Heatsink Specs
Material and Conductivity
JOYJOM uses pure copper, which offers a thermal conductivity of 401 W/mK. This is significantly higher than the aluminum alloy used by Awxlumv, which conducts at 237 W/mK. Copper moves heat away from the source faster than aluminum. Awxlumv uses anodized aluminum for corrosion resistance and general purpose cooling. JOYJOM covers its copper with graphite to look black, though some red copper may show. For pure thermal transfer speed, copper is the superior material choice. This gives JOYJOM a clear advantage in heat dissipation capability per unit of mass.
Compatible Device
JOYJOM is designed specifically for M.2 2280 SSDs, laptops, and PS5 consoles. It fits standard NVMe drives. Awxlumv is a generic block for IC chips, NEMA17 stepper motors, and regulators. It works on 3D printers like Creality or Ender 3. You cannot use JOYJOM for a stepper motor, and Awxlumv is too large for an M.2 slot. They target different components entirely. If you have an SSD, JOYJOM is the only option. If you have a motor or chip, Awxlumv is the fit. This is a tie based on your specific hardware.
Dimensions and Fit
JOYJOM measures 70x20x2mm, making it very thin and wide for flat SSD surfaces. Awxlumv measures 40x40x20mm, creating a cube shape. The 2mm height of JOYJOM is critical for laptops with tight clearance. Awxlumv’s 20mm height is for passive cooling on larger components where space allows. Awxlumv comes in a 4-pack, giving you multiple units for different chips. JOYJOM is sold singly with a thermal pad. Choose JOYJOM for flat drives and Awxlumv for bulky components needing more surface area.
Included Accessories
JOYJOM includes a thermal pad, rubber rings, and bandages. The thermal pad is silicon grease based and low viscosity to protect warranty labels. Awxlumv does not include any adhesive or paste. You must buy thermal glue separately to install it. JOYJOM’s package is ready to mount immediately. The bandages help secure the unit in place. Awxlumv requires you to source your own mounting solution. For ease of installation, JOYJOM provides the necessary components. Awxlumv leaves that step to you.
Weight and Mass
JOYJOM weighs 1.06 ounces. Awxlumv weighs 1.45 ounces per unit. Copper is denser than aluminum, so JOYJOM packs more mass into a smaller volume. Awxlumv is lighter but less dense. The higher mass of copper helps JOYJOM absorb heat spikes better. Awxlumv’s lighter weight is suitable for small electronics where heavy loads matter less. For thermal inertia, the heavier copper unit performs better. Awxlumv is lighter, which is fine for low-power chips. JOYJOM wins for heavy-duty heat absorption.
Choose the right heatsink for your needs
PS5 or laptop owners needing low profile
JOYJOM fits M.2 2280 SSDs with a slim 2mm height. The pure copper core provides 401 W/mK conductivity, moving heat faster than aluminum. Graphite coating aids dissipation. It includes a thermal pad and rubber rings for secure attachment. This design prevents throttling in tight laptop or console spaces without adding bulk.
DIYers cooling stepper motors or IC chips
Awxlumv offers a 4-pack of 40x40x20mm aluminum blocks. This bulk is ideal for passive cooling NEMA17 motors or power devices. The anodized surface resists corrosion. Each unit weighs 1.45 oz. You get multiple units for various components. The 20mm height provides ample surface area for generic electronics that do not require specialized mounting hardware.
Users wanting maximum thermal conductivity
JOYJOM uses pure copper with 401 W/mK thermal conductivity. This outperforms the 237 W/mK rating of Awxlumv’s aluminum alloy. The material choice ensures rapid heat transfer from the source to the fins. The groove design increases surface area further. This makes it the superior choice when specific thermal performance metrics are the primary concern for your hardware.
