Liquid Metal vs Thermal Paste for CPUs: Conductivity Data, Compatibility, and Long-Term Behavior
Liquid metal thermal compounds have thermal conductivity 10 to 50 times higher than premium paste compounds. The performance advantage is real on high-TDP CPUs with small heat spreaders, but aluminum heatsink incompatibility, conductive spillage risk, and difficulty reversing the application make it a scenario-specific choice rather than a universal upgrade.
