6 Best Alternatives to the JOYJOM 2mm Graphite-Coated Copper M.2 (2026)

Comparing Alternative M.2 Heatsinks

Haojiaho 6mm Pure Copper M.2 2280 Heatsink

The Haojiaho 6mm heatsink shares the pure copper construction but increases thickness to 6mm, compared to the 2mm original. This extra mass provides greater thermal capacity, making it suitable for desktops or consoles with ample clearance. It includes a thermal pad for direct contact. You gain cooling performance but lose the ability to fit in low-profile laptop slots where the JOYJOM model excels. Choose this if your device allows 6mm height and you prioritize heat absorption over compactness. The copper finish remains exposed, unlike the graphite-coated original, which may affect aesthetics but ensures direct thermal transfer without an additional coating layer.

Haojiaho 67x18x2mm Pure Copper M.2 Heatsink

This Haojiaho 2mm heatsink matches the original's thickness but uses bare copper without graphite coating. It is slightly smaller at 67x18mm versus 70x20mm, offering a tighter fit for very constrained spaces. The weight is lower at 0.56 ounces, which reduces overall drive mass. It includes a thermal pad for installation. You get a simpler, uncooled copper surface that may require more precise surface contact. This option is ideal for users who want the low profile of the original but prefer the look and direct conductivity of bare copper over graphite. It sacrifices some surface area for a more compact footprint in tight laptop bays.

Easycargo 100-Piece 15mm Copper Shim Kit

The Easycargo shim kit differs significantly by offering 100 copper shims rather than a single heatsink block. It allows you to customize the gap between your SSD and cooler, ensuring perfect contact. Unlike the JOYJOM model, it does not provide passive cooling fins. You use these shims to fill voids, improving thermal transfer to an existing cooler. This is best for builders who already have a heatsink but need to adjust for uneven SSD surfaces. It provides precision fit rather than raw cooling capacity. The shims are 15mm square, requiring you to cut or arrange them as needed. It complements other coolers rather than replacing them entirely.

SGTKJSJS Copper M.2 2280 Laptop Heatsink

The SGTKJSJS heatsink is a larger copper block at 3x0.87 inches, compared to the 2.76x0.79 inches of the original. It weighs 2.89 ounces, nearly three times heavier, providing more thermal mass for passive cooling. It is designed for 2280 SSDs in laptops. It includes a thermal pad. The larger surface area may offer better heat dissipation in open chassis, but the increased size might not fit in all laptop slots. Choose this if you have a desktop or open-air laptop with space for a bulkier cooler. It lacks the graphite coating, relying solely on copper conductivity. It is a robust alternative for users who can accommodate its larger dimensions.

Icepc Graphene Copper M.2 Heatsink

The Icepc 2mm heatsink is nearly identical in size to the JOYJOM model at 70x20x2mm but weighs less at 0.71 ounces. It uses pure copper with a black finish, similar to the graphite-coated original. It includes a thermal pad for installation. The key difference is the lack of specific graphite coating claims, relying on copper's natural conductivity. It is suitable for laptops and PS5 consoles. You get a lighter, thinner profile with comparable dimensions. This option is ideal if you want a standard copper heatsink without the graphite layer. It offers reliable cooling in tight spaces, matching the original's footprint while providing a different material finish and lower weight.

Icepc 4mm Pure Copper M.2 Heatsink

The Icepc 4mm heatsink increases thickness to 4mm, doubling the original's 2mm profile. It maintains the same 70x20mm footprint, making it compatible with similar mounting areas. It uses pure copper with a thermal pad. The extra height allows for more thermal mass, improving heat dissipation for PS5 and laptop SSDs. You gain cooling performance but lose compatibility with ultra-thin laptop slots. This model is best for users who have 4mm clearance and want better passive cooling. It lacks the graphite coating, offering bare copper conductivity. The increased size makes it a practical upgrade for devices that can accommodate the extra height without compromising other components.
