All equipment is designed to work within a certain range of
environmental conditions. Operating outside that range will generally
result in immediate failure or a dramatic decrease in reliability. Even
within the range there can be wide variations in expected life and
efficiency.

As for your motor, if cooling is required to keep its internal
temperatures to within design limits, then indeed it is highly likely
that it could spin faster and/or use fewer amps if cooled.

Not that not all electrical & electronic devices (if hot) work better if
cooled. If the device is designed to run hot, then cooling it to a
temperature outside its design limits could easily result in it becoming
non-functional or unreliable.

For example, an electronic timing crystal is often put in an oven
designed to heat it to a constant temperature. Attempting to cool it is
not going to be beneficial.. As another example, I have a small pump
designed to circulate molten solder - it won't even turn when cooled to
room temperature..
