AOSEEAquarium Chillers Fish Tank Cooling Fan Aquarium Cold Wind Chiller Decoration Accessory Heat Dissipation Fans for Salt Fresh Water(4 Fans)

Excellent, efficient cooling fan that reduced my 200 L tank temperature by 3 degrees. After struggling in the latest heat wave to reduce my marine tank temperature I was relieved to find this product and more importantly to find out it worked. It is a lot cheaper than a cooler, my only negative is it is a bit noisy on the high setting.

The product may be fine and probably is, but in the description its promised to fit 1.5cm aquarium. Mine is 1.2cm, but the product didn't fit, because the narrowest points are just 1cm. Its unfortunate, as based on the score the product was quite promising. Giving a neutral review, as it will probably work fine for different aquariums. I'll need to return it and buy a different one...

Cheap rubbish. Very noisy. Power supply blew on first day. Tried an aftermarket multi voltage and the high power only occassionally works. Don't waste your money on this.

It works fine, but had to return the first one as plug was broken, second one comes and low and behold plug is broken so had to buy a plug on top if buying this!

This a joke I got my parcel but no power cable or screws how am I meant to use it

The product states that it’s suited for tank rims that are 15 mm thick. My tank has a rim that is 15 mm thick but it still didn’t fit. I realised it’s because the two ends of the support for the fan are thicker than the middle and therefore only provide a gap suitable for a tank rim of 13 mm. What’s the point in even making the fixture that small when there are screw used to tighten and secure it onto thinner rims?

These fans took down temperature of my tank quickly good value for the money they cost

A mi me ha funcionado bastante bien, me baja los grados rápido y tiene bastante potencia, se oye algo pero como si te pones tú el ventilador en casa es normal, lo recomiendo

1 ventilateur sur les 4 ne fonctionne pas j'ai renvoyer le colis

J'ai reçu le produit aujourd'hui pour mon aquarium d'axolotl.Il commençait à faire chaud.J'ai placé le ventillo à 19 h, l'eau était déjà monté à 21.2.A 20 heures en vitesse 1, elle a perdu 1 degrés.En mettant la vitesse 2 ensuite j'ai réussi à baisser l'eau à 19.6. vers 21 hC'est pas encore la canicule mais c'est encourageant.Au vu des commentaires, je m'attendais à quelque chose d'extrêmement bruyant.J'ai agréablement été surprise. Oui ça fait le bruit d'un ventillo, mais en même temps, on ne peut pas déplacer de l'aire rapidement en silence.Le bruits n'est pas choquant, et en vitesse 1 c'est même assez discret.

Würde ich wider kaufen

Uso este ventilador de 4 unidades en un acuario de 450 litros. En cuestión de 2 horas es capaz de bajar entre 1 y 1.5 grados la temperatura de los 450 litros de agua, con la velocidad baja.Uso la velocidad baja para que haga menos ruido y porque prefiero que la bajada de temperatura sea más gradual o lenta.En breve le añadiré un controlador de temperatura para que se ponga en marcha y se pare automáticamente en un rango concreto de temperaturas.No puedo opinar sobre durabilidad, pero de momento estoy encantado con el producto y se está usando bastante este verano ;)
