Hot, every manufacturer's materials suggest warmed up.

Following a run, warm oil flows better than cold,
contaminants in the oil are more likely to be in suspension, vs settled out in the pan, so they will get out... which is primarily why we change the oil...

with a practical caveat: if engine parts are going to burn you doing it "hot", your eternal salvation won't be put in jeopardy by waiting a short while for that particular external to cool a bit...

Or, is this topic similar to anchor selection?
