Yes, almost everyone who perished died because they froze to death. Totally the reverse scenerio when only 30 died on Titanic's younger sister ship Britannic when she sank near the island of Kea in the Aegean Sea. The water was warm that day, and the only reason 30 passengers died was because a lifeboat was launched without permission. They were unfortunately chopped up by the still turning propellers now starting to stick out of the water as Captain Bartlett tried to beach Britannic.
