How effective can the sound of a fan be? Just read this user review:
“This music is cheaper than a new fan, well except those electrical hazards waiting to happen you find in the cheapo shops. So I paid my money and downloaded.
“Finally I could close my eyes and turn my hifi up to just the right level to hear the fan just like it was here with me... cooling me... and it worked, I felt so much cooler, as if a magic glacier of ice was sliding over me.”
