    • Great for keeping our Axolotl cool…
Size: 4-Head
This unit does a nice job in cooling down our 40 gallon tank. I read others concerned with the noise however it is no worse than the white noise of a standard fan. I would give it 5 stars if it were not for the inability to attach it securely to a tank with a lip as most have; we have ours clamped and the outer edge resting on the lid. ... show more

    • Works
Size: 3-Head
This is a nice little fan system. It did work on keeping my aquarium water cooler. My electric bill was a lot higher using it. So, I do not use it as much now.

    • Wouldn't buy again
Size: 3-Head
Biggest issue is that it wouldn't attach to the side of my standard 20 gallon tank as expected. Second issue is within a week it started making a high pitched scream occasionally which I had to turn off the fan and back on to resolve, not huge deal but annoying. Does cool the tank by about 5-7 degrees fahrenheit. But for the price I recommend just getting a desk fan with a clip. ... show more

    • Good basic fan chiller
Size: 3-Head
Bigger than I thought, 3 fan system for for a Evo 13.5, so a little overkill. We don't notice when it kicks on though it's basically in our bedroom by way of master bath, so pretty quiet but definitely not a whisper quiet. I have it hooked to a temp controller, and I live where it being106° degrees for weeks, my tank stays ~78° (+/-) 1°. Pushes good. Would buy another. ... show more

Brings my Temp down pretty quick and has low and high fan switch Big improvement on the Plug in size over the big heavy converter I had with another brand fan. Does the same job i had with a 4 fan I had before on my 60 gallon tank.

    • Good little cooler

The media could not be loaded. We bought this for our axolotl tank in the basement. It was hovering around 70-71 in the heat of summer so we wanted to bring it down a little bit. This did the trick. On hot days it goes down to 68 and cooler days it’s 66 just on the low setting. On the low setting it doesn’t make much more noise than a filter but the high setting isis noticeably louder. You do have to watch though if you have a rim on your tank you’ll need an adapter. Luckily I had someone 3d print one for me. Overall a good little fan that does exactly what we wanted it to do. ... show more

    • Way to loud
Size: 4-Head
Sadly even if it looks functional the noise it makes its way to loud. It's not pleasing if you have visits, or even want to sleep... I have the aquarium in the living room and I can clearly hear it in my room with the door closed.
