Try it! Identical trays, different water temps, same spot in the freezer. When I first heard it, I didn't believe it either. A couple of times it was a bit faster, most time it was hard to tell, but it was never slower. (I was judging by if I could see liquid water move inside the cube) It was more obvious in a bigger container than an ice cube tray.
