The fan seems powerful and does the job, although noisy, yet the controller is cheap garbage. The first third of the controller does nothing. fan won't even work no matter where you put the dial. Once you pass the 1/3 point, the fan won't work continuously at low speed. It repeatedly turns on/off instead. From almost half the dial, the fan starts to work AT HIGH SPEED! there is no smooth low-speed fan here! Then towards the max, the fan is slightly noisy (but reasonable compared to the airflow it generates). I would have returned it, but worked to make something DIY so not worth the hassle, I am not happy with it, especially as it doesn't have the low speed that I needed. ------ Update ---- The seller reached out and offered a refund or replacement and nicely tried to address any issue. I declined as I have already installed the fan in my DIY project, but it is nice to be kind! ------ 1-year Update ---- This fan has been running in our bathroom for a full year now, 24/7 (we never turn it off, even when no one is using the bathroom. It is always running). It is up and running like its first day! I am impressed by the quality of it. no noise, no issue, and it is still as powerful as the first day. I would buy it again and would highly recommend it!!!!

I recently installed the Wathai 120mm x 38mm 360mm Computer Fan in the wall of my chicken coop, and it has been a game-changer for managing the heat. With Florida's intense heat, this fan has successfully dropped the temperature by 3-4 degrees, making it much more comfortable for my chickens. The fan's powerful airflow, rated at 135CFM per fan and adjustable speed up to 3000 RPM, ensures efficient ventilation. I love that it comes with a variable speed controller, allowing me to fine-tune the airflow to keep noise to a minimum while maintaining effective cooling. Installation was straightforward with the included screws, rubber feet, and speed controller. The fan's compact size and robust build make it a versatile choice for various applications, but it's been perfect for my coop. The ball-bearing motors promise a long lifespan, which is reassuring given the continuous use. Overall, this fan has significantly improved the air quality and temperature in my chicken coop. It's a reliable and powerful solution for ventilation. Highly recommend it for anyone needing effective cooling in similar settings!

I used these fans to build a circulation tower for a room with a sliding door with no ventilation. One at top pulling air from the room to the corridor and one at the bottom pulling air from the corridor to the room. At mid setting, Low noise and still pulls enough air!

I've had several normal floor fans. They last about a year before the bearings dry out and seize up. This costs about the same, move more air, and the four fans are in their third year with no problems. I now have two- one in my kitchen, one in my bedroom, both as window fans.

After long hours of search and several tryes of different fans, this was the only one that fit well my vertically open window. And it worked great for two months thru rains, winds, dust etc. You may need to purchase extra brackets and insulating foam to make it stay secure and survive the winter. I now have 4 fans, and think about upgrading it to 8.

We installed this with magnetic mounts in our storm shelter over the bottom vent. Bringing in air pressure from below allows us to push the hot air out the top vent. Super easy to use and exactly the function we were looking for to keep our storm shelter cool.

This is a fan that you would maybe use as a vent.... for a small room, or a space... BUT This is not a fan you probably want in a space where noise is an issue. The variable speed is mediocre at best. While it does go slowish...to fast.... the minimum RPM is still loud since this is not really a hi-tech fan.... So.. It moves air well, has good speed variation and power...... but at no time is it quiet at any speed. So I wouldn't recommend using this in spaces where you don't want some significant white noise.

I use a two-fan combination to help cool my laptop. OMG - these things are a bit loud, but they're AWESOME!!!! I've tried a couple of different laptop "cooling pads" and they were OK. These controllable fans are perfect for my situation! I love them so much, that I'm actively trying to find other things where I can incorparate them into various projects!!!!
