Liquid metal thermal paste is a coolant that’s applied between the CPU chip and the heat spreader to reduce friction between them. This type of paste has a higher heat dissipation capacity than standard thermal pastes and is ideal for overclockers, gamers, and PC enthusiasts with high-performance builds.
There are a few things to keep in mind when selecting liquid metal thermal paste. First, it’s important to consider the application method. Many liquid metal pastes come in syringe-style applicators, which can be used to apply the product with precision. Other products feature spreadable forms that allow for easy, evenly distributed coverage of the surface. Both options can be effective, but it’s important to consider your skill level and desired precision when evaluating the application method of any thermal compound.
Another thing to consider is the longevity of the thermal paste. Most traditional thermal compounds will last for 8 years before the binders and fillers break down and degrade. However, liquid metal pastes may need to be redone after 1-2 years as the gallium slowly eats away at the metal surfaces it’s on.
For those interested in trying out a liquid metal thermal paste, there are plenty of options available on the market. A popular option is Thermal Grizzly Kryonaut, which features a mildly viscous consistency and good stability after application. It also cleans up easily with isopropyl alcohol, making it a favorite among system builders. Unlike most conventional thermal pastes, this specific product does not contain graphite or zinc. However, it should not be used with silicone-sensitive components or with aluminum coolers, as the gallium content can cause galvanic corrosion.
