MECCANIXITY 20x20mm 2mm Copper Shims Alternatives: 6 Similar Picks Compared

How these copper shims compare

MECCANIXITY 20x20mm 0.3mm Copper Shims

The MECCANIXITY 20x20mm 0.3mm copper shim shares the same brand and adhesive backing as the original, but it is significantly thinner. At 0.3mm, it offers minimal height adjustment compared to the 2mm profile of the primary pick. This makes it better suited for small chips or memory modules where space is tight. You lose the substantial gap-filling capability of the 2mm version, but gain a low-profile solution that fits delicate components. If your goal is precise cooling on small surfaces rather than lifting a large heatsink, this thinner option is the practical choice. It retains the easy peel-and-stick application but sacrifices the structural thickness needed for major spacing corrections.

PATIKIL 15x15x0.3mm Copper Heatsink Shims

The PATIKIL 15x15x0.3mm copper shim differs in both size and thickness. It is smaller at 15x15mm and thinner at 0.3mm, making it ideal for compact laptop components or small GPUs where the 20x20mm footprint is too large. This product is best for users needing precise gap filling on tight spaces rather than broad coverage. You give up the larger surface area and the thick 2mm profile, but gain a solution that fits smaller chips more accurately. It lacks the adhesive backing mentioned for the original, so you must apply thermal paste separately. This pick suits those prioritizing exact fitment on small devices over the convenience of pre-applied adhesive.

PATIKIL 15x15x0.4mm Copper Heatsink Shims

The PATIKIL 15x15x0.4mm copper shim is another small-footprint option, measuring 15x15mm with a 0.4mm thickness. It is designed for correcting minor thermal interface gaps on GPUs or chipsets in tight spaces. Compared to the original 20x20mm 2mm shim, this is much smaller and thinner, making it unsuitable for large height adjustments. It is better for users who need a precise fit on smaller components without excess material. You trade the broad coverage and significant spacing capability for a compact design that fits specific small chips. Like the other PATIKIL option, it does not mention an adhesive backing, requiring you to manage thermal interface materials yourself. It is a practical choice for minor gap corrections on compact hardware.

NEW Games Order PS3 Copper Heatsink Shims

The NEW Games Order PS3 copper shim kit is a specialized solution for PlayStation 3 maintenance, featuring 42x42mm copper spacers. It is significantly larger and thicker than the 20x20mm 2mm original, making it incompatible with standard desktop PC components. This kit includes thermal paste and is tailored for console repair rather than general PC cooling. You give up the universal desktop application and the specific 20x20mm size, but gain a targeted solution for YLOD repairs on specific consoles. It is not suitable for general CPU or GPU cooling in computers. This pick is strictly for users needing specific spacers for PlayStation 3 hardware, offering a different scale and purpose entirely compared to the versatile desktop shims.

JIUWU 15x15x0.8mm Copper Heatsink Shims

The JIUWU 15x15x0.8mm copper shim is smaller and thinner than the original, measuring 15x15mm with a 0.8mm thickness. It is designed for laptop GPU or CPU gaps where the 20x20mm footprint is too large. This option is better for users needing a mid-range thickness for compact components rather than the significant 2mm height adjustment of the primary pick. You sacrifice the larger surface area and greater spacing capability for a fit that suits smaller laptop chips. The data does not mention an adhesive backing, so you must apply thermal paste manually. It is a practical choice for laptop maintenance where precise sizing and moderate thickness are required for proper thermal contact on smaller processors.

JIUWU 20x20mm Copper Pad Shim

The JIUWU 20x20mm copper pad shim shares the same 20x20mm footprint as the original but is much thinner at 0.8mm. It is designed for filling moderate gaps on GPUs and chipsets where the 2mm thickness is excessive. This option is better for users who need a mid-range thickness to improve cooling without the significant height adjustment of the 2mm version. You give up the substantial spacing capability but gain a shim that fits components with smaller gaps. The data does not mention an adhesive backing, requiring you to use thermal paste for installation. It is a practical solution for those needing a precise fit on components where the original shim would be too thick, offering similar coverage with reduced height.
