A thick layer is the most common installation mistake, because excess paste adds resistance rather than removing it. The anodised layer is a protective oxide, which is why the block is designed to sit in an aluminium loop rather than a copper one: mixing the two metals in one wet circuit invites galvanic corrosion. Corner holes accept standard mounting hardware, and the gasket face is machined square so the same seal can be reused after a cleaning pass.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-applications\" style=\"margin-top:30px;\"\u003e\n\u003ch3\u003eWhere It Gets Used\u003c\/h3\u003e\n\u003cp style=\"line-height:1.8;\"\u003eInside a compact PC loop where a full CPU block will not fit, on a high-power LED array where the star board cannot shed heat on its own, on thermoelectric cooler assemblies that need a hot-side sink, and inside small enclosures where airflow barely exists.
