LONDAFISH Aquarium Chillers Aquarium Fan Fish Tank Cooling Fan Marine 2 Fan

This arrived at around 4pm, my tank with the current heat was at 29°C... it was opened and on My tank in 5 minutes, current time 19:35, my tank is now at 26°C, its no more noisy than the big air fan I currently have trying to blast a bit of cold air into the house.(105L tropical aquarium) the fish seem a lot happier now that the water is cooler

Ottimo prodotto! In un 70 lt la temperatura è più bassa di 3/4 gradi rispetto a quella della stanza! Consigliatissime per i mesi più caldi

The fan didn’t fit my aquarium which has a rim, had to 3D print ”adapters” to make it work. But the fan itself works great and lowered the temp by 5 degrees celcius in my 120litres aquarium on the lowest setting. The higher setting is quite loud.

tiene dos velocidades, el ruido no se nota mucho, y baja la temperatura entre dos y tres grados. tiene un tornillo para ajustarlo al borde del acuario

Perfect for my nano tank, it cools the water by few degrees which is just enough to keep it to 25° during the summer.The only design issue is that it's one-sided and the mounting screws are on the inside, so you'll have to dip your fingers in the water while setting it up.
