Review on Black Zoo Med Aqua Cool Aquarium Cooling Fan: Enhancing Efficient Temperature Control by Mallory Roberts

I have a small 10 gallon axolotl tank that, despite my best efforts to keep the tank in good condition with frozen water bottles, reached 70 degrees in the summer. This fan was my only viable option and it works well. This fan constantly lowers the water temperature by 3-5 degrees Fahrenheit. My biggest concern with this fan would be the potential for noticeable water movement, but the air slides easily over the top and doesn't bother the axolotl. I could complain about the noise but to be honest I don't notice it and it's a fan so it's silly to think it will be completely silent. Overall, this is a great little investment for warm aquariums.
