6 Best Alternatives to the Alphacool 14 x 14mm Copper (2026)

Comparing alternative heatsink options

Alphacool 10 x 10mm Copper RAM Heatsinks

The Alphacool 10 x 10mm Copper RAM Heatsinks are a smaller variant of the original. While the original measures 14 x 14mm, this alternative uses 10 x 10mm copper blocks. Both are passive cooling solutions made from pure copper for GPU or RAM modules. You should choose this option if your components have tighter spacing that cannot accommodate the larger 14mm footprint. The cooling method remains passive, relying on ambient airflow rather than fans. The material and application are identical, but the reduced surface area may limit heat dissipation on high-power chips. This pack is ideal for compact builds where space is the primary constraint, not thermal headroom.

Easycargo 15x15x0.5mm Copper Shims 20-Pack

The Easycargo 15x15x0.5mm Copper Shims differ significantly in form factor. Instead of block-style heatsinks, these are thin shims measuring 15 x 15mm with a thickness of 0.5mm. They include thermal tape for mounting, whereas the original Alphacool heatsinks rely on standard adhesion or mechanical pressure. This alternative is better suited for laptop VRAM or chipset cooling where height restrictions are extreme. The larger 15mm surface area provides more heat spread than the 14mm original, but the thin profile offers less mass for heat storage. You should pick this kit if you need to fit cooling components under tight clearances on mobile devices or low-profile motherboards.

Easycargo 100-Piece 15mm Copper Shim Kit

The Easycargo 100-Piece 15mm Copper Shim Kit is designed for gap filling rather than dedicated heatsinking. These 15 x 15mm copper pads are versatile tools for M.2 SSDs and laptop components. Unlike the original Alphacool heatsinks, which are thicker blocks, these shims are primarily used to adjust height or improve thermal contact. They offer the same pure copper conductivity but lack the structural height to act as significant heat sinks on their own. This kit is best for builders who need to fill small thermal gaps or level components rather than add substantial cooling mass. It provides more pieces for the price, making it useful for large-scale projects or multiple small adjustments.

Easycargo 20mm Copper Pad Shim Kit

The Easycargo 20mm Copper Pad Shim Kit offers even larger copper surfaces at 20 x 20mm. These pads are intended for filling small thermal gaps with high conductivity copper. They differ from the original 14mm heatsinks by providing a broader base for heat spread, which can be beneficial for VRM or SSD cooling. The thickness is not explicitly stated in the specs, but the larger footprint allows for better contact area. You should choose this alternative if your components require a wider heat dissipation surface than the square 14mm blocks provide. It is a practical solution for builders who need to manage heat over a broader area on graphics cards or storage devices.

Easycargo 14mm Copper Heatsink 10-Pack

The Easycargo 14mm Copper Heatsink 10-Pack is the closest direct alternative to the original. It matches the 14mm footprint and uses pure copper for passive cooling of GPU VRAM and laptop memory. However, it includes thermal tape for mounting, which may offer a more secure attachment than standard adhesive. The dimensions are slightly different, measuring 0.47 x 0.55 inches with a height of 0.2 inches. This alternative is suitable if you need the same size but prefer the included mounting tape for stability. It serves the same function as the Alphacool option but may be preferred for its specific mounting solution and competitive positioning in the market.

Bopaodao 120mm Flat Copper Heat Pipe

The Bopaodao 120mm Flat Copper Heat Pipe is a fundamentally different component. It is a 120mm long, 5.5mm wide, and 2mm thick flat copper pipe rather than a small block heatsink. This item is designed for DIY passive cooling on laptop or GPU backplates, requiring manual integration. It does not offer the same easy mounting as the original Alphacool heatsinks. You should choose this if you need to enhance heat spread across a larger area on a backplate. It provides a different cooling mechanism, acting as a heat spreader rather than a localized sink. This option is best for advanced builders willing to customize their cooling setup for specific thermal challenges.
