Yes, you would only need to turn off slient running when your internal ship temperature is reaching dangerous levels. If you have turned off all heat generating systems then you can stay in slient running indefinitely. However, in this state your are effectively in a passive state of silent running anyway and don't need to switch it on because:

All systems off with 0% internal heat being generated to radiate out via your radiators is effectively the same as Silent Running where your radiators are closed and zero internal heat is being radiated out via your radiators. You look the same to other ships under both conditions.
