Thermal Grizzly TG Putty Basic 100g Thermal Pad

Thermal Grizzly TG Putty Basic is an electrically non-conductive alternative to conventional thermal pads. As an easy-to-apply and flexible gap filler, it compensates for height differences, making it ideal as a replacement for thermal pads on GPUs. Because graphics cards typically feature several types of thermal pads of varying thicknesses from the factory, TG Putty simplifies replacement and cooler conversion work. This is the 100g size with medium thermal conductivity, part of the Basic line. Available at Alfrensia for 2,099 EGP.

Why Choose Putty Instead of Thermal Pads?

Graphics cards typically use thermal pads of different thicknesses across the PCB. Some areas have thin gaps, while others have large gaps between the PCB and the backplate. Replacing pads means ordering multiple thicknesses and cutting them to size, which is time-consuming and error-prone. Because TG Putty is a flexible gap filler, it adapts to any gap size and does not require precise cutting. As a result, you can replace all the pads in a GPU with a single container of putty. This saves time and reduces the risk of using a pad that is too thick or too thin, which can lead to poor contact or damaged components.

Variants and Thermal Conductivity

TG Putty is available in three versions that mainly differ in their thermal conductivity. Each variant is designed for different requirements in heat dissipation and is available in 30g and 100g sizes. The Basic variant offers medium thermal conductivity, which is suitable for VRAM and VRM cooling where the thermal load is moderate. The Advance variant offers good thermal conductivity for higher-performance cards, and the Pro variant offers very good thermal conductivity for demanding applications. This listing is the Basic variant in 100g size.

Recommended TG Putty Amount

For modifying a single, smaller graphics card without an active backplate, such as a GeForce GTX 1060, approximately one 30g container of TG Putty is required. For larger graphics cards, such as a GeForce RTX 4090, one 30g container is generally sufficient for the memory (VRAM) and voltage regulators (VRM) on the front side. On the backside of larger cards, there is often a uniform, larger gap between the PCB and the backplate. In this case, approximately two 30g containers are needed to completely fill this gap. The 100g size therefore provides enough material for a full RTX 4090 repaste, including backside gap filling, with some left over for additional work.

Application Guide: How to Apply TG Putty

Before application, the target surface should be thoroughly cleaned and degreased, for example, using TG Cleaning Wipes or conventional isopropanol. Remove the old pads and residue from the PCB, the cooler, and the backplate. Once the surfaces are dry, take a small amount of putty and shape it by hand or with a spatula. Press it gently onto the areas where pads were originally located, such as over the VRAM chips and VRM components. Because TG Putty stays flexible, it will compress and fill the gap evenly when the cooler is tightened down. Do not apply putty directly to the GPU die or processor IHS. After mounting the cooler, tighten the screws in a diagonal pattern, one turn at a time, to ensure even pressure.
