What happened
A two-year electron microscope test reported by Tom's Hardware found that liquid metal thermal interface material does not 'dry out' — instead the gallium bonds with copper coolers and turns solid. Nickel plating kept that reacted layer roughly 10 times thinner than on bare copper. Note: the supplied text is almost entirely site navigation and membership boilerplate, so only the headline-level findings are available to verify; no test methodology, sample sizes, or performance deltas were provided.
Why it matters
This only changes a decision if you are choosing a cooler or thermal paste for a machine you actually run hot for long periods — the concrete claim is that bare copper plus liquid metal forms a solid gallium-copper layer over two years, while nickel plating keeps it about 10x thinner. If you're not repasting or building high-thermal-load rigs, there is nothing here to act on, and the article body was not readable in the supplied text, so treat the numbers as a headline claim rather than a measured result you can plan around.
Discussion angle
For anyone maintaining long-running local dev or GPU boxes: does a two-year solidification finding change your repaste interval or push you toward nickel-plated coldplates — and would you trust a headline-only claim with no visible methodology?
