I use two of these fans for my 40 gallon reef aquarium. I was very upset if they could cool my tank, but I wasn't willing to shell out around $1,000 for a professional cooler. I put them in my inkbird temperature controller and they do the job well. My tank is always between 77-78. The fans, which is very important to me, are quite quiet. Highly recommended for nano aquariums.
