I know that ESC's get hot at that point as they need to push more current to make the motor spin undr load...wondering if the motor does the same or just stays coooool?!?!

If you are referring to gearing, then the first situation you mention is undergearing, whilst the second is overgearing. Motors will not get really hot if you are simply driving slowly with correct gearing as they pull only as much current as they need. Current pretty much equals heat, so as it draws less current, it will be cool. ESCs on the other hand do not like 'partial load' applications, as they are least efficient then.
