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!

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