About this tag
Thermal interface materials are the compounds placed between a processor and its cooler to improve heat transfer, and this tag collects WindowsForum.com discussion of how they behave in real builds. Coverage centers on liquid metal TIM, including a two-year electron microscope investigation into why gallium-based pastes appear to dry out and crust over. The explanation involves chemical reactions with copper, nickel, and aluminum rather than evaporation, which matters for anyone cooling a high-end gaming rig or overclocked system. Threads here help PC builders and enthusiasts choose a TIM and understand long-term compatibility with common heatsink and cold plate metals.

    Liquid Metal TIM Doesn’t Dry Out: Gallium Reactions With Copper, Nickel and Aluminum Explained

    If you have ever pulled the CPU cooler off a high-end gaming rig after a year or two of running liquid metal thermal interface material (TIM), you have probably experienced a brief moment of panic. Instead of the shiny, mercury-like puddle you painstakingly brushed onto the die, you are greeted...
