    Default Heat Sink anodizing

    Heat sinks tend to be anodized, but not always black.

    Is this a safety feature because the anodized layer is an insulator? as anodized coatings have a much lower thermal conductivity than aluminum.

    More like to prevent galvanic corrosion.

    They always anodize the heatsinks. Even when they are silver, they are "clear anodized".

    Hadn't thought about that; but wouldn't corrosion build up an oxide layer and so stop on its own accord?
