  The Pi 4 does, but it looks like you can pair the Shake seismometer hats with the Pi Zero W, those run fine with passive cooling (especially bolted to a concrete slab in the basement, I'd say).

  The Raspberry Pi 400 doesn’t have one. I believe it throttles back when too hot.

    the 400 has a metal parts of the case as a passive cooling surface, so it fares better than the "naked" Pi 4.
