Aquarium Chillers Cooling Fan, ColdWind Cooling System for Salt/Fresh Water (2 Fan)

Perfect size for my 3.7 gal shrimp tank. Seems to work pretty well and cools the tank a bit, it is a bit noisy but it doesn’t bother me. Also it’s cheap so

These fans work very well for my aquarium. They do take a while to cool down the tank and few degrees but it works great for the Illinois climate I live in. If you need a strong fan that works quick and you need a cool or cold tank but I suggest these for like 10 to 20 gallon tanks. It works very well for my 15 gallon.

The clip that should be used to mount the fans to the aquarium did not fit my aquarium top. I had to find some way to run some wire thru the unit and to other cords (ie: my power head & air pump) to keep this unit in place. Otherwise fans fell over the back of the aquarium if bumped, etc.The fans themselves run fine. Decent quality/price.

I mean it does the job and brings the temperature of my 10 gallon down roughly 3 degrees but its a little bit glitchy, honestly you get what you pay for and its either this or a $200 chiller so its kinda just settling.

I purchased this to draw new air through a bio active vivarium with live plants, lichen and moss. Works beautifully with glass Versatops, both 20L and 55G. Low noise. The connector did come loose and had to be super glued, but this is the only issue and totally fixable. I’d buy it again for future builds.

Our axolotl loves the fan as it drastically cools down his rimless tank. It was loud at first but after a few days it is virtually silent.

Cooled down my axolotol tank perfectly!! Highly suggest. I used this on a 30 gallon tank.

The edge of my 55 gallon tank was too thick to clamp it on, but I was able to use a pair of 2 inch c clamps instead. This thing works great so far, cooled my tank down from 82 to the ambient room temp of 76. In fact it works too well, I'm losing water through evaporative cooling. So I've ordered a heat/cool thermostat so it only runs when needed.
