Thermal Grizzly TG Putty Pro 100 alternatives are here if you need a different approach to gap filling. The original product excels at conforming to irregular surfaces to eliminate air pockets between heatsinks and components. Its putty-like consistency allows for precise application without the mess of traditional pastes. However, you might prefer a solid shim for better structural stability or easier removal later. Some builders also want specific material options or pre-sized kits that save time during assembly.

We selected these 5 picks because their specifications overlap with the original use case. Each item in this list offers copper or aluminum conductivity suitable for cooling small components like RAM, VRMs, or M.2 SSDs. You can choose based on whether you need adhesive backing, specific dimensions, or pure metal conductivity. The Easycargo and Alphacool kits provide rigid solutions for precise spacing. These alternatives focus on material properties and size flexibility rather than paste application. This guide helps you find the right spec for your build without guessing.

Our top pick: Easycargo 100-Piece 15mm Copper Shim Kit.

How these copper shims differ

Easycargo 124-Piece Multi-Size Aluminum and Copper Kit

This kit uses aluminum and copper pads with thermal tape, unlike the putty that conforms to gaps. It offers pre-sized pieces for Raspberry Pi or M.2 SSDs, saving you the effort of cutting material. The adhesive backing simplifies mounting small components directly. You lose the ability to fill irregular voids, as these are rigid plates. Choose this if you need standardized sizes for multiple small devices rather than custom gap filling. The mix of materials allows you to balance weight and conductivity for different parts of your build.

Easycargo 20mm Copper Pad Shim Kit

This option provides larger 20mm copper pads, which differ from the small, precise application of the original putty. It is ideal for filling larger gaps around RAM or VRMs where rigidity is acceptable. The pure copper material ensures high thermal conductivity, similar to the putty’s metal content. However, you cannot shape it to fit uneven surfaces. Pick this if you have consistent gaps on standard components. It offers a straightforward solution for spacing issues without the mess of a paste, focusing on direct contact and heat transfer for larger areas.

GeeekPi 102-Piece Aluminum and Copper Heatsink Kit

This kit includes 102 pieces of aluminum and copper heatsinks with thermal tape, targeting Raspberry Pi and small electronics. It differs from the putty by offering rigid, pre-formed solutions rather than a malleable filler. The adhesive tape allows for quick installation on multiple ICs. You sacrifice the ability to seal irregular air pockets completely. Select this if you need to cool several small components simultaneously. It is best for builders who prefer standardized, easy-to-mount heatsinks over custom gap-filling materials for their small form factor builds.

Alphacool 10 x 10mm Copper RAM Heatsinks

These 10x10mm copper heatsinks are designed for passive cooling of GPU RAM and MOSFETs. Unlike the putty, which fills gaps, these attach directly to components to dissipate heat. They offer targeted cooling for specific small areas without adding bulk to the entire system. You give up the versatility of gap filling for focused thermal management. Choose this if your goal is to lower temperatures on specific chips rather than improving contact between a heatsink and a flat surface. It is a specialized solution for silence and targeted heat dissipation.

Alphacool 14 x 14mm Copper Heatsinks 10-Pack

This pack contains 14x14mm copper heatsinks for GPU RAM and MOSFETs. It differs from the putty by providing rigid, high-conductivity pads for direct attachment. The larger size compared to the 10x10mm version covers more surface area on memory chips. You lose the flexibility to fill irregular spaces, as these are fixed plates. Opt for this if you need reliable passive cooling for graphics card components. It fits builders who prioritize direct heat transfer from specific ICs rather than general gap elimination between major cooling blocks.

Frequently asked questions

Can copper shims replace thermal putty for gap filling?

Yes, copper shims provide a solid alternative for managing gaps between heatsinks and components. Unlike putty, these rigid pads offer precise thickness control. You can select specific sizes, such as the 15mm or 20mm options, to fit exact spacing needs without the need for curing time or messy application.

Which material conducts heat better for small electronics?

Copper generally offers higher thermal conductivity than aluminum, making it ideal for targeted cooling on small components. The Easycargo 15mm and 20mm kits use pure copper for this reason. If you need versatility across multiple devices, some kits combine both materials, allowing you to choose based on your specific thermal requirements.

Are these shims suitable for RAM and VRM cooling?

Yes, many of these kits are designed specifically for RAM, VRMs, and GPU components. The Alphacool copper heatsinks and Easycargo shims are compatible with these small areas. They help dissipate heat from memory chips and power delivery modules, ensuring stable performance without adding significant bulk to your build.

Do I need adhesive tape for installation?

Some kits include thermal tape to simplify mounting, while others rely on direct contact or separate adhesive. The Easycargo 124-piece and GeeekPi kits come with thermal tape for easy application on Raspberry Pi or M.2 SSDs. Other copper shim packs may require you to source your own adhesive for secure attachment.

What sizes are available for custom gap filling?

You can find a wide range of dimensions to match your specific gaps. Options include 15mm, 20mm, and various other widths and lengths. The Easycargo 15mm kit offers 0.6-inch pieces, while the 20mm kit provides larger 1.57-inch by 6.02-inch pads. This variety allows you to fine-tune spacing for different components.

Are these alternatives good for Raspberry Pi cooling?

Yes, several kits are optimized for Raspberry Pi and similar small electronics. The Easycargo 124-piece and GeeekPi 102-piece kits include multiple sizes ideal for cooling various ICs on a Pi board. Their compact dimensions and included thermal tape make them easy to install on the small form factor boards.
