Not directly. The internal ventilation fans on the Villa and Tiny both run on 12V DC (the Villa draws around 2 watts and the Tiny is around 1.5 watts). The supplied mains adaptor reduces the 230V AC mains supply to 12V DC.
If you want to run the fan from a 24V supply, we would recommend fitting a voltage regulator to reduce the 24V DC supply to 12V.
