No, the primary concern is voltage surges and spikes, though motor and bearing
wear certainly increases.  I'd turn the monitor off because high voltage
power supplies are more susceptible to damage and breakdown than low voltage
power supplies, and the potential for damage is probably greater if you
leave the monitor on all night.  Conversely, I'd leave the CPU on.
