Which one should you choose?
Choose Easycargo 9mm Anodized Heatsink if
- You need to cool multiple stepper motor drivers on a 3D printer.
- You require a larger fin height for better passive airflow.
- You want a higher quantity of heatsinks for a larger build.
Choose Easycargo 9mm Copper VRM Heatsinks if
- You are cooling VRM or MOSFET components on a motherboard or GPU.
- You need copper for faster heat transfer in tight spaces.
- You have limited vertical clearance for the heatsink height.
Verdict: Choose the aluminum kit if you are building a 3D printer and need to cover several stepper drivers. Pick the copper kit for VRM or GPU cooling where space is tight and rapid heat dissipation is critical. Your choice depends entirely on the component you are trying to cool.
Heatsink Material and Size Comparison
Material and Conductivity
The Easycargo 9mm Anodized Heatsink uses aluminum, which is lighter and corrosion-resistant but less conductive than copper. The Easycargo 9mm Copper VRM Heatsinks are made from pure copper. Copper has higher thermal conductivity, allowing it to absorb and dissipate heat more efficiently from the component surface. If you prioritize maximum heat transfer speed, copper is the superior choice for passive cooling applications where space allows for the material density.
Heatsink Height and Profile
Profile matters for clearance in tight spaces. The Easycargo 9mm Anodized Heatsink stands 0.47 inches (12mm) tall. The Easycargo 9mm Copper VRM Heatsinks are only 0.16 inches (4mm) tall. Both share the same 9mm x 9mm base footprint. The copper version is significantly shorter, making it ideal for low-profile VRMs or MOSFETs where vertical clearance is limited. The aluminum version offers more fin surface area due to its height, which can help with air circulation in slightly more open areas.
Package Quantity
You need to consider how many heatsinks you actually require for your build. The Easycargo 9mm Anodized Heatsink comes in a kit of 30 pieces. The Easycargo 9mm Copper VRM Heatsinks come in a kit of 10 pieces. If you are cooling multiple stepper motor drivers on a 3D printer, the 30-piece aluminum kit provides more units per package. For a standard motherboard VRM setup, the 10-piece copper kit is likely sufficient and may offer better value per unit of material.
Compatible Devices
Target application dictates which kit fits your needs. The Easycargo 9mm Anodized Heatsink is explicitly listed for 3D printers, specifically for stepper motor modules like TMC2130 or A4988. The Easycargo 9mm Copper VRM Heatsinks target VRM, GPU, MOSFET, and regulator cooling on laptops and PCs. While both work for passive cooling, the copper version is marketed for higher-density electronic components found in computing hardware, whereas the aluminum version is tailored for printer electronics.
Mounting Method
Both kits simplify installation by including pre-applied adhesive. The Easycargo 9mm Anodized Heatsink uses 3M 8810 thermal conductive adhesive tape. The Easycargo 9mm Copper VRM Heatsinks also feature pre-applied thermal conductive adhesive tape. This means you do not need to buy separate thermal pads or screws for mounting. Both options offer a clean, tool-free installation process, sticking directly to the component surface to ensure good thermal contact without extra hardware.
Which Easycargo Heatsink Suits You
You need high thermal conductivity for VRMs
Copper offers superior thermal conductivity compared to aluminum. This kit includes ten 9mm x 9mm x 4mm copper heatsinks. The material efficiently absorbs heat from VRM modules, MOSFETs, and voltage regulators. The low profile fits tight spaces while maximizing heat transfer performance for sensitive electronic components.
You are cooling 3D printer stepper drivers
This kit contains thirty anodized aluminum heatsinks designed for stepper motor drivers like TMC2130 and DRV8825. The 9mm x 9mm x 12mm size provides ample surface area for passive cooling. The blue anodized finish resists corrosion, making it ideal for the environment of a 3D printing setup.
You want a larger quantity for bulk projects
You receive thirty pieces in this package, which is three times the quantity of the copper option. Each aluminum heatsink measures 9mm x 9mm x 12mm. The included 3M 8810 thermal adhesive tape ensures secure mounting. This bulk count is practical for multi-driver setups or spare inventory.
