Thermal Grizzly Hydronaut Pro 6g
Thermal Grizzly Hydronaut Pro 6g.

Thermal conductivity sets how much heat crosses from the chip to the cooler, while viscosity and service life decide how often the job has to be redone, since a compound that dries out gradually loses performance. A thin, even layer works better than a generous blob, and electrically conductive types call for care, as a drop on the board can short components.
