a man is found hanging from the ceiling riddle

Answer: He was standing on the Ice Block

Solution:

Keeping the things in mind:
Visualizing a room with just a fan and a man hung on it, with some water on the floor.

The first thing that strikes my mind is that He had a rope in his neck tied to the fan and was standing on a big ice cube/ice slab.

As the ice started melting, he starts dying.
