Specs: Pads vs Shim Kit
Thickness options
The Newzoll 40-Piece Copper Heatsink Pads offer two thicknesses: 0.5mm and 1mm. These come in both 15x15mm and 20x20mm sizes. The Newzoll Copper Heatsinks Shim, 4 Sizes provides 0.8mm, 1.0mm, and 1.5mm options. Both kits include ten pads per size. If you need very thin gaps, the first kit is better. If you need thicker fillers, the shim kit is superior. The shim kit covers a wider range of gap heights, which helps with uneven surfaces.
Material quality
Both products use pure copper as their primary material. This ensures high thermal and electrical conductivity for effective heat transfer. Each kit features a smooth surface with no burrs on the edges. This finish helps in creating a better contact area between components. You get 40 pieces in each pack. The material specification is identical for both options. This means you do not lose performance by choosing one over the other based on metal quality.
Weight
The Newzoll 40-Piece Copper Heatsink Pads weigh 3 ounces. The Newzoll Copper Heatsinks Shim, 4 Sizes weighs 4.23 ounces. The difference is due to the thicker copper in the shim kit. A lighter kit is easier to handle and store. The heavier kit provides more material mass per pad. This might help with heat capacity slightly. You should choose based on how much weight you want to add to your project.
Compatible devices
Both kits list the same compatible devices. They work with notebooks, CPUs, GPUs, RAM, VGA, and IC chips. The recommended use is heat conduction and gap filling. This improves heat dissipation and reduces repair rates for graphics cards. You can use them for passive cooling in DIY Arduino projects. There is no difference in compatibility. Both are suitable for the same electronic components and cooling scenarios.
Model number
The Newzoll 40-Piece Copper Heatsink Pads have the model number 21FR00039. The Newzoll Copper Heatsinks Shim, 4 Sizes uses model 21FR00040. These numbers help you identify the exact product when ordering. They distinguish the two different thickness profiles. You should check the model number if you need to reorder or replace pads. The model number does not affect performance, but it ensures you get the correct size set.
Which Newzoll copper kit suits you
Need thin 0.5mm pads for tight gaps
The 40-Piece Copper Heatsink Pads include 0.5mm thickness options. You get ten pads each of 15x15mm and 20x20mm at this thin profile. This kit allows precise filling for narrow spaces between components like RAM or VGA chips. The pure copper material ensures efficient heat transfer without adding significant height to your setup.
Require thicker 1.5mm shims for large gaps
The Shim kit offers 1.5mm thickness options for both 15x15mm and 20x20mm sizes. You receive ten pads of each size and thickness. This greater depth helps bridge wider gaps between graphics cards and thermal modules. The pure copper construction maintains high thermal conductivity while providing the necessary structural fill for uneven surfaces.
Prefer lighter kit for portable builds
This kit weighs 3 ounces, making it lighter than the alternative. The reduced weight is useful for portable notebook repairs or lightweight DIY Arduino projects. You still get the full set of four sizes with pure copper pads. The passive cooling method remains effective for dissipating heat from CPUs and GPUs without adding bulk.
