Now you mentioned, on my D400 the slave is always warm on standby, while the master is cool. This is same on 440?
Yes, it's the same on all models. With RCA cable, when you power off the master, the companion doesn't power off, it goes into stand by. You have to use trigger cable for both to power off.
