Both peltiers (look for thermoelectric coolers on Amazon/Newegg) and phase change coolers are used by PC enthusiasts, but it’s not that common because regular liquid cooling is good enough for everyday use, and you don’t need to waterproof everything to protect against condensation when the cooler gets below the dew point. Not to mention mould...

Cooling below the dew point results in condensation. Moisture on a circuit board is bad

Inconvenience is no obstacle to over-clocking.
