As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You might be looking for haojiaho copper heatsink 1 57x1 57x0 24 inches alternatives if the standard 40x40x6mm block does not fit your specific thermal needs. This original heatsink uses pure copper for efficient passive cooling and includes adhesive tape for easy installation on ICs and circuit boards. It is a solid choice for small components that require silent, zero-noise operation without the complexity of fans. However, you may need different dimensions or a specific material mix for your project.
The alternatives on this list were chosen because their specs overlap with the original, offering various sizes and configurations. Some options provide smaller footprints for tight spaces, such as the 15mm or 9mm shims. Others offer multi-packs for cooling several chips at once, like the Raspberry Pi kits. You can also find specialized units for laptop RAM or 3D printer motors. Each product here shares the core passive cooling and adhesive mounting features, but they vary in physical dimensions and compatible devices to suit your exact requirements.
Our top pick: Haojiaho 40x40x6mm Copper Heatsink.
How the alternatives compare
Easycargo 15x15x0.5mm Copper Shims 20-Pack
The Easycargo 15mm Copper Shims are significantly smaller than the Haojiaho block. They measure 15x15x0.5mm compared to the 40x40x6mm original. This thin profile suits tight spaces on laptop components like VRAM. You lose surface area, so heat dissipation is less robust. However, the adhesive tape ensures easy application. Choose this if you need to cool small chips where the Haojiaho heatsink is too large or thick. It is a practical choice for compact laptop repairs.
Easycargo 20-Piece Copper and Aluminum Heatsink Kit
This kit offers a mix of copper and aluminum materials. The Haojiaho heatsink is pure copper. The kit includes 20 pieces of varying sizes. This variety helps when cooling multiple chips on a Raspberry Pi. You get flexibility in sizing, which the single large Haojiaho block cannot provide. The aluminum pieces conduct heat less efficiently than pure copper. However, the quantity allows you to cover several components at once. Pick this option if you have multiple small chips to cool rather than one large surface.
Easycargo 9mm Copper VRM Heatsinks
The Easycargo 9mm Copper VRM Heatsinks are much smaller. They measure 9x9x4mm, whereas the Haojiaho heatsink is 40x40x6mm. These are designed for multiple small MOSFETs or VRM components. You sacrifice the large surface area of the original for targeted cooling. The pack includes nine units for widespread application. Use these if you need to cool several small electronic components on a circuit board. The Haojiaho block is too bulky for these specific, tight spots. This kit provides the necessary coverage for complex boards.
Easycargo 40mm Copper Heatsink 2-Pack
This 40mm Copper Heatsink shares the same width and length as the Haojiaho model. Both are 1.57 inches square. However, the Easycargo version is only 4mm thick, compared to the 6mm original. This thinner profile reduces weight and material use. It still uses pure copper and adhesive tape. Choose this if you need the same footprint but less height. It is ideal for 3D printer motors or Peltier coolers where space is limited vertically. You get similar cooling performance in a slimmer package.
Easycargo SODIMM Copper Memory Heatsink
The Easycargo SODIMM Copper Memory Heatsink is shaped for RAM modules. It measures 0.91 by 2.48 inches. This is a long, narrow strip, unlike the square Haojiaho heatsink. It is designed specifically for laptop SODIMM slots. You cannot use this for general IC cooling or CPU boards. The shape is specialized for memory chips. Pick this alternative if you are cooling laptop RAM. The Haojiaho block is too wide and short for this specific application. This heatsink fits the slot perfectly with adhesive backing.
Easycargo 10mm Copper VRM Heatsink Kit
The Easycargo 10mm Copper VRM Heatsink Kit is very small. Each unit is 10x10x4mm. The Haojiaho heatsink is 40x40x6mm. This kit provides ten small units for multiple chips. You gain the ability to cool several components simultaneously. The individual surface area is much smaller than the original. Use this for small VRM or IC chips where space is tight. The Haojiaho block is overkill for these tiny components. This kit offers precision placement for dense circuit boards with many small heat sources.

Frequently asked questions
Are all these alternatives made of copper like the Haojiaho block?
Most options use copper for its high thermal conductivity. The Easycargo 15mm Shims, 9mm VRM Heatsinks, 40mm Pack, SODIMM Heatsink, and 10mm Kit are all pure copper. However, the Best Budget kit includes both aluminum and copper pieces. Aluminum is lighter but less conductive than copper.
Do these heatsinks come with adhesive for installation?
Yes, every listed product includes thermal adhesive tape. This allows you to stick them directly onto components without drilling or complex mounting hardware. The Haojiaho 40x40x6mm block features thermal tape, and all Easycargo variants also come with pre-applied adhesive for straightforward application.
Which alternative is best for cooling laptop RAM modules?
The Easycargo SODIMM Copper Memory Heatsink is designed specifically for this task. It measures 0.91 by 2.48 inches to fit standard laptop memory slots. This compact copper shim provides passive cooling for SODIMM modules, helping to keep your laptop RAM temperatures under control.
Can I use these for cooling 3D printer motors?
Yes, the Easycargo 40mm Copper Heatsink 2-Pack is ideal for this. It measures 1.57 by 1.57 by 0.16 inches, matching the footprint of NEMA 17 motors. The adhesive backing allows you to attach it directly to the motor housing for effective passive heat dissipation.
What is the smallest heatsink available in this list?
The Easycargo 9mm Copper VRM Heatsinks are the smallest option. Each unit measures 0.35 by 0.35 by 0.16 inches. They are packed in sets of ten, making them perfect for cooling multiple small MOSFETs or VRM components where space is extremely limited.
Is there a kit that offers multiple sizes for different chips?
The Easycargo 20-Piece Copper and Aluminum Heatsink Kit is the best choice. It includes 20 mixed pieces in various sizes and materials. This variety allows you to cool several different small chips on a Raspberry Pi or similar board without needing to buy separate units.
How does the thickness of the Easycargo shims compare to the Haojiaho block?
The Easycargo 15mm Shims are much thinner at 0.5mm compared to the Haojiaho block's 6mm height. This thin profile is better for tight spaces like laptop chipsets. The Haojiaho block is thicker, providing more surface area for passive cooling on larger ICs.
