Thermal Grizzly TG Putty Pro 100g Thermal Pad
Thermal Grizzly TG Putty Pro is a 100g thermally conductive gap filler featuring very good thermal conductivity, a flexible and easy-to-apply formula, and electrically non-conductive design. It is an ideal replacement for conventional thermal pads on GPUs, VRAM, and VRM, compensating for height differences between components and coolers.
⚡ Engineering Highlights at a Glance:
- Very Good Thermal Conductivity: Pro variant delivers the highest thermal conductivity in the TG Putty lineup for demanding heat dissipation.
- Flexible Gap Filler: Compensates for height differences between components and coolers, ideal for GPU thermal pad replacement.
- Easy to Apply: Spreadable putty consistency allows precise application on VRAM, VRM, and other components.
- Electrically Non-Conductive: Safe to use near exposed circuitry without risk of short circuits.
- 100g Container: Ample quantity for multiple GPU modifications or large graphics cards.
- Three Variants Available: Basic (medium conductivity), Advance (good conductivity), and Pro (very good conductivity) to suit different requirements.
- Ideal for GPU Cooler Conversions: Perfect for replacing factory thermal pads when converting to a GPU water cooler.

Expert Advice & Application Considerations
Recommended TG Putty Amount
For modifying a single, smaller graphics card without an active backplate (e.g., GeForce GTX 1060), approximately one 30-gram container of TG Putty is required. For larger graphics cards such as a GeForce RTX 4090, one 30-gram container is generally sufficient for the memory (VRAM) and voltage regulators (VRM) on the front side. On the backside, there is often a uniform, larger gap between the PCB and the backplate on larger graphics cards—approximately two 30-gram containers are needed to completely fill this gap.
⚠️ Important Usage Notes
TG Putty is not suitable for use on processors (IHS or Direct Die) or directly on the GPU die. It is designed specifically as a gap filler for VRAM, VRM, and other components where thermal pads are typically used. Before application, the target surface should be thoroughly cleaned and degreased, for example using TG Cleaning Wipes or conventional isopropanol.
🔧 Application Tips
Apply TG Putty in a thin, even layer over the components requiring thermal transfer. The putty’s flexible consistency allows it to fill gaps and conform to uneven surfaces. Use a plastic spatula or applicator to spread the putty evenly. Avoid applying excessive force that could damage components. After application, mount the cooler or water block according to the manufacturer’s instructions.

Expert Recommendation: Getting the Most from Your TG Putty Pro
Before applying TG Putty, thoroughly clean and degrease the target surface using TG Cleaning Wipes or isopropanol. Apply the putty in a thin, even layer over VRAM, VRM, and other components requiring thermal transfer. Use a plastic spatula to spread the putty evenly and ensure full coverage. Mount the cooler or water block according to the manufacturer’s instructions, applying even pressure to ensure proper contact. For larger graphics cards with a backplate gap, use additional putty to fill the space completely. Avoid using TG Putty on processors or directly on the GPU die. Store the container in a cool, dry place when not in use. The 100g size provides ample material for multiple GPU modifications or large graphics cards.
Frequently Asked Questions
What is Thermal Grizzly TG Putty Pro used for?
TG Putty Pro is a thermally conductive gap filler designed as an alternative to conventional thermal pads. It is ideal for replacing thermal pads on GPUs, particularly for VRAM and VRM cooling.
What is the difference between TG Putty Basic, Advance, and Pro?
The three variants differ in thermal conductivity: Basic offers medium thermal conductivity, Advance offers good thermal conductivity, and Pro offers very good thermal conductivity. Each is available in 30g and 100g sizes.
Can TG Putty Pro be used on a CPU or GPU die?
No. TG Putty is not suitable for use on processors (IHS or Direct Die) or directly on the GPU die. It is designed specifically as a gap filler for VRAM, VRM, and other components where thermal pads are typically used.
How much TG Putty is needed for a graphics card?
For smaller graphics cards without an active backplate, approximately one 30-gram container is required. For larger cards like the RTX 4090, one 30-gram container is sufficient for the front side, but approximately two 30-gram containers may be needed for the backside gap between the PCB and backplate.
Is TG Putty Pro electrically conductive?
No. TG Putty is electrically non-conductive, making it safe to use near exposed circuitry without risk of short circuits.
How should I prepare the surface before applying TG Putty?
Before application, the target surface should be thoroughly cleaned and degreased, for example using TG Cleaning Wipes or conventional isopropanol.
