Haojiaho 6mm Pure Copper M.2 Alternatives: 6 Similar Picks Compared

How each alternative compares

JOYJOM 2mm Graphite-Coated Copper M.2 Heatsink

The JOYJOM heatsink uses pure copper like the original but reduces thickness to 2 mm. This 70 x 20 x 2 mm profile fits tight laptop clearances where the 6 mm Haojiaho model will not. You gain compatibility with slim devices but lose the larger surface area of the thicker original. The weight drops to 1.06 ounces, making it lighter for portable builds. It includes a thermal pad for direct contact. Choose this if your priority is fitting into constrained spaces without sacrificing copper conductivity. The slightly narrower width also aids in dense motherboard layouts.

Haojiaho 67x18x2mm Pure Copper M.2 Heatsink

This Haojiaho 2mm heatsink offers a slimmer 67 x 18 x 2 mm profile compared to the original 70 x 21 x 6 mm model. It uses pure copper to maintain thermal efficiency while significantly reducing height. At 0.56 ounces, it is much lighter than the original. This design suits users with tight laptop M.2 slots where the taller original heatsink causes clearance issues. You trade some cooling surface area for a form factor that fits smaller devices. The included thermal pad ensures proper heat transfer. Select this option if you need a low-profile solution that still leverages copper's superior thermal properties for compact systems.

Easycargo 100-Piece 15mm Copper Shim Kit

The Easycargo kit provides 100 copper shims rather than a single pre-formed heatsink. These 15 mm shims allow you to create custom gap-filling solutions for M.2 SSDs. Unlike the original Haojiaho heatsink, this kit does not offer a unified cooling surface. It is ideal for builders who need specific thicknesses to fill irregular gaps around SSDs or GPUs. You gain flexibility in customizing your cooling setup but lose the convenience of a ready-to-install heatsink. The copper material ensures good thermal conductivity. Pick this if your build requires precise gap filling rather than a standard heatsink design for standard 2280 drives.

SGTKJSJS Copper M.2 2280 Laptop Heatsink

The SGTKJSJS heatsink measures 3 x 0.87 inches and weighs 2.89 ounces. It uses pure copper for thermal management. This model is designed for 2280 SSDs in laptops with tight clearance. It differs from the original Haojiaho 6mm model by offering a different form factor that may suit specific screw placements or space constraints. The included thermal pad aids in heat transfer. It is a practical choice for users who find the original dimensions difficult to install. Choose this alternative if you need a copper heatsink that fits well in tight laptop spaces where standard mounting options are limited or problematic.

Icepc Graphene Copper M.2 Heatsink

The Icepc heatsink features a graphene-coated copper construction with a 70 x 20 x 2 mm size. This 2 mm thickness is significantly slimmer than the original 6 mm Haojiaho model. It weighs only 0.71 ounces, making it lighter for portable use. The graphene coating may enhance thermal performance compared to bare copper. It fits PS5 and laptop 2280 SSDs with tight clearance. You gain a slim profile and potential thermal benefits but give up the thicker mass of the original. Include this if you want enhanced copper cooling in a low-profile design that fits constrained spaces without sacrificing too much surface area.

Icepc 4mm Pure Copper M.2 Heatsink

This Icepc heatsink is 4 mm thick, sitting between the original 6 mm model and the 2 mm alternatives. It measures 70 x 20 mm and uses pure copper. The 4 mm height offers a balance between thermal mass and clearance. It suits users with 70x20mm SSDs who need more cooling than the 2mm version provides but cannot fit the 6mm original. It includes a thermal pad for installation. The weight is not specified, but the reduced height makes it suitable for laptops with moderate space constraints. Choose this if you need a mid-range thickness that retains copper conductivity without the bulk of the tallest option.
