Thermal Grizzly has introduced Thermal Putty, which can be described as a “liquid thermal pad.” The new product is easy to use and, unlike traditional thermal pads, serves as a flexible gap filler that compensates for the difference in height between the heating elements and the cooling system.

The power elements of the video card power subsystem, which heat up during operation, are equipped from the factory with thermal pads of different heights. Over time, they wear out and become less effective, so they need to be replaced to prevent overheating.
Thermal Putty can compensate for differences in height from 0.2 to 3 mm, making this thermal interface a versatile solution. “Liquid thermal pads” can be applied in two ways: over a large area using the included spatula or by hand (it is recommended to do this with a glove). When applied manually, the new product can be formed into small balls in accordance with the size of certain contact surfaces (for example, video memory chips or SMD components). And when installing the cooling system, the downforce will create the correct thickness of the thermal pad, squeezing out the excess.
Liquid thermal pad TG Thermal Putty is available in three versions, mainly differing in thermal conductivity:
- Putty Basic has a medium thermal conductivity and costs $16.24;
- Putty Advance with increased thermal conductivity and costs $27.14;
- Putty Pro has high thermal conductivity and costs $43.49.
All options are supplied in 30 ml jars. TG Thermal Putty liquid thermal pads do not conduct electricity.
It should be noted that to improve heat transfer between the GPU or CPU and the cooling system, it is still advisable to use traditional thermal paste or liquid metal.
