hygger Aquarium Chillers Fan, Quiet Fish Tank Cooling Fan Equipment with Adjustable Timer Speed Controller, Suitable for Freshwater Saltwater Tanks(1-Fan Head)

my apartment gets up to ~80-85 in the evenings during the summer. I have a 10g tank that was also getting up to ~85, and attaching 2 fans on the lowest setting dropped it from 82 to 78 in 2 hours (stopped watching the temperature after that), while my apartment ambient temperature was roughly 83. all the settings are quite quiet, though i haven't had the product for long and it seems like similar items to this may develop louder noises due to their own vibration & build quality. none of that so far though. very happy with efficacy and ease of use for this item. for a rough idea of the sound level, on max setting, you'd hear it if it were in your room at night, but it's not particularly noticeable during the day with any other sounds going on. for the lowest setting, you have to get very close to hear it running. another reviewer reported that you could set this up with a temperature controller. I'm thinking of doing that, looks like to do so, you just skip the speed&timer controller piece in the middle of this setup. the wall adapter can plug straight into the 3-way power splitter just as easily

Excelente

Tengo unos pequeños ajolotes que con el tiempo van necesitando cada vez más espacio. Antes los tenía en una pecera de 10 litros y los ventiladores me funcionaban muy bien pero ahora que los cambié a una de 40 litros no logra bajar la temperatura menos de 18 grado. Así que este producto es bueno pero no para litrajes grandes. P.d. Soy de la cdmx y actualmente (05/24) estamos sufriendo olas de calor pudiera ser uno de los motivos del porque no enfría más.

Quise hacerle limpieza por todo el polvo que se acumula y de la nada se desoldó un cable

Love this. It keeps my tank cool for the axolotl
