6 Best Alternatives to the Ellbest 30pcs 15 x 15 (2026)

How the alternatives differ

NEW Games Order PS3 Copper Heatsink Shims

The NEW Games Order kit targets PlayStation 3 repairs with significantly larger 42x42 mm shims. This contrasts sharply with the Ellbest 15x15 mm pads, which are designed for small laptop components. The NEW Games Order option includes thermal paste, whereas the Ellbest kit provides only copper shims. Its packaging dimensions are much larger, reflecting the scale of console hardware. You should choose this if you are cooling a PS3 GPU or VRAM. The Ellbest remains better for compact laptop repairs where space is tight. The larger surface area of the NEW Games Order shims helps dissipate heat from larger chips, but the fit is not universal across all devices.

JIUWU 15x15x0.8mm Copper Heatsink Shims

JIUWU offers a thinner 0.8 mm profile compared to the Ellbest 1 mm thickness. This makes it suitable for laptops with tighter clearance constraints. The JIUWU pack contains 20 pads, which is fewer than the Ellbest quantity of 30. Both use pure copper for thermal conductivity. You should pick JIUWU if your hardware requires a slimmer shim to fit under existing components. The Ellbest is better if you need more pads or can accommodate the extra 0.2 mm thickness. The JIUWU pads are optimized for specific small-gap scenarios, while the Ellbest provides a standard thickness that works for many general laptop GPU and CPU applications.

JIUWU 20x20mm Copper Pad Shim

The JIUWU 20x20 mm shim provides a larger surface area than the Ellbest 15x15 mm pad. It shares the same 0.8 mm thickness, which is slightly thinner than the Ellbest 1 mm option. This larger footprint is ideal for covering bigger memory chips or GPU cores. You should choose this if your components require more coverage area. The Ellbest is better for smaller chips where the 15x15 mm size is precise. Both are made of pure copper. The JIUWU option sacrifices some thickness for width, which may affect how it sits against the heat spreader. It is a practical choice for builders who prioritize surface contact over the standard compact size.

Uxcell 20mm Pure Copper Thermal Shim

Uxcell provides 20x20 mm pads that are 1.0 mm thick, matching the Ellbest thickness but offering a larger area. The Ellbest pads are 15x15 mm, which fits smaller chips better. Both use pure copper for heat dissipation. The Uxcell option is better for larger gap-filling scenarios on GPUs or laptops where space allows for the 20 mm size. You should pick Uxcell if you need to cover more surface area without increasing thickness. The Ellbest remains the better choice for compact components. The Uxcell pads are designed for builders who need to bridge wider gaps on larger memory chips, providing a robust thermal solution without the need for thicker materials.

Honbay 15x15mm Copper Heatsink Pads

Honbay offers a versatile range of thicknesses for its 15x15 mm pads, unlike the Ellbest which is fixed at 1 mm. This allows you to select the exact thickness needed for your specific hardware gap. Both brands use copper and maintain the same 15x15 mm footprint. You should choose Honbay if your laptop or GPU requires a non-standard thickness for proper contact. The Ellbest is better if you prefer a standard 1 mm profile and a bulk quantity of 30. Honbay’s flexibility is its main advantage, catering to precise thermal management needs. The Ellbest provides simplicity and consistency for general repairs where the 1 mm thickness is sufficient.

Alphacool 10 x 10mm Copper RAM Heatsinks

Alphacool provides 10x10 mm copper heatsinks, which are smaller than the Ellbest 15x15 mm pads. This smaller footprint is ideal for RAM chips or MOSFETs that require less surface area. Both use pure copper for thermal conductivity. You should pick Alphacool if your components are small and need a compact solution. The Ellbest is better for larger chips that benefit from the 15x15 mm coverage. The Alphacool pads are designed for precision cooling on tiny components. They are a practical choice for builders who need to cool specific small areas without covering unnecessary space. The Ellbest remains the standard for general laptop GPU and CPU cooling where larger pads are needed.
