Product review (5 stars): Works great! No more foam!
I previously tried fashioning my own tower cooler with a computer fan but should have bought this first! The fan in this is audible but still fairly quiet. The install was fast and within minutes I had condensation forming on the tower. Now even the first pour of the day is frosty and there's no foam! If you don't have a tower cooler, save yourself the trouble and but this one.

Also the customer service is great!
