Poafamx Aquarium Chiller, DC12V Aquarium Cooling Fan with 3-Speed Adjustable Controller, Cross-Flow Fish Tank Cooler for Axolotl, Automatic Temperature Control Aquarium Cooler (4W)

I absolutely love this fan it keeps the temperature on my fish tank a constant temperature it's super quiet and does exactly what it's advertised to do

Worked well for our axolotl tank for less than 3 months-Then one very cool morning we came out and the fan was on and it said it was 79 degrees and it was actually 60 degrees.

Drops my tank about 4 degrees

It does not do the job, it’s been on for a long time on max speed and lowers temperature and it still has the same temperature since the first day, 72 degrees F which is not good for my axolotl 😡😡😡😡😡

Hey there! I just had to share my thoughts on the Poafamx Aquarium Chiller I recently picked up for my fish tank, and let me tell you, it's been a game changer! it’s a steal for the quality you get.First off, the design is super sleek and compact, making it easy to fit on my tank without taking up too much space. I love how it uses that innovative cross-flow technology to really amp up the air circulation. My fish seem to be thriving, and I can totally see the difference in the water temperature—it cools things down quickly, which is a must for keeping my aquatic friends happy.The auto temperature control feature is a lifesaver! I set it to my desired temp, and it does all the work for me. The large screen display is also a nice touch, allowing me to keep an eye on the water temperature and fan speed at a glance. Plus, it operates at a whisper-quiet level, so it doesn’t disturb the peaceful vibe of my tank.Installation was a breeze, too! It mounts easily on the tank walls, and with the adjustable angle, I can direct the airflow exactly where it’s needed. It’s versatile enough for both freshwater and saltwater, which is fantastic.Overall, I highly recommend the Poafamx Aquarium Chiller! It’s efficient, quiet, and easy to use—perfect for anyone looking to create a comfy environment for their aquatic life. Seriously, my fish are loving it, and I couldn't be happier with my purchase!

I was unable to secure the fan to the top of my 40 gallon Aqueon standard tank which I converted into a sump tank for my 125 gallon reef tank. I was hoping the fan would provide a little bit of evaporation to cool off the main tank. At one point, the fan even fell off its mount on the rim and into the sump tank water. I gave up, your efforts may vary.

I was doubtful of the design, but it actually works. I keep Ranchu's and they like their water cool. During the Summer, it's always a problem when the room temperature is above their comfort zone. Especially in the winter with the heating. At first I just used a cheap USB fan. But that was more a spot cooling solution. I then used a bank of fans and that did the job, but I had to hang it across the tank for adequate coverage. And it needed to be on constantly because there was no temperature control.This unit does the job by attaching to the side of the tank. No need to remove it to clean the tank. The linear airflow is strong enough to blow across the entire surface of my 55Gallon tank. With cooled air that exits the unit. Not room temperature air like the fans. It keeps the tank cooler with less usage. Once the water temperature reaches the desired setting, it auto shuts off. The airflow is also does a great job agitating the surface, to not only keep it clean, but helps aerate it. And it does it quieter than the old fans. May be pricey to some, but well worth it if your fish like cooler water temps.

Doesn’t tell you how to put together
