Oh, the days a computer could get away with just a heatsink instead of 20 fans...

  The heatsink cools the LM7805 power regulator, not the CPU. In the original 48k Spectrum, the heatsink was internal.

    And if you use a modern switch-mode replacement, you don’t need a heat sink at all. I know some folks like to put small heat sinks on the ULA though.

      Soviet clones had ULAs built from individual 74xx ics. No need for heatsinks!

        Excellent! I need to mess around with them at some point.

    Well, that's an outlier. Even the M2 Mac Mini I typed the previous post on has a fan.
