20 Best Liquid Metal Thermal Paste (2023 Updated)

Liquid metal thermal paste is a type of thermal paste that uses a liquid metal compound as its primary heat-conducting ingredient. Unlike traditional thermal pastes that use a silicone or metal oxide base, liquid metal thermal paste has a much higher thermal conductivity, making it ideal for use in high-performance applications such as gaming PCs and overclocked CPUs.

Conclusion

As its name suggests, liquid metal thermal paste is in a liquid state at room temperature. Unlike traditional thermal pastes, it’s made with a metal alloy and doesn’t contain any silicone. It’s also electrically conductive, so it’s not recommended for use on circuits.

Liquid metal thermal paste has excellent thermal conductivity, making it ideal for use on CPUs and GPUs. It’s also easy to apply, and it doesn’t dry out or crumble over time like traditional thermal pastes.

The only downside to liquid metal thermal paste is that it’s more expensive than traditional thermal pastes. However, it’s worth the extra cost if you’re looking for the best possible thermal conductivity.
