Should I turn the fan off as the lights go off?

Hi Naoki ,
Fifty degrees is ok, but not much lower than that for vandas, except for very short periods of time. I do usually turn my fan off at night when it gets down below 55, so long as the plants are dry. If it has been a damp cloudy day and things are still a little wet, I leave it on down to the 50 degree mark.
In your case, with the plants indoors, I wouldn't worry too much, so long as it doesn't drop below 50 for more than a few hours. Your plants will benefit more from the circulating air than from any potential damage caused by the cool temps.
I hope this helps!
