Good controller, good fans
These are good, solid fans, and come joined together with a removable bracket. They also come with a set of 4 “feet”, making it useful to set on other devices for cooling.At full blast, 170CFM for the pair, they are fairly noisy. But with the controller set to the 9 or 10 o’clock position, they are fairly quiet. To be honest though, if you were to use these for studio or home theater gear, there are much more quiet fans available.I’m using them with HEPA filters for workbench “clean area” use, so the noise is not a relevant factor.

Decently quiet fans with a nice speed controller
I have been using these fans (the three-fan configuration) for several days now, and so far they’re excellent. I am using them to bring in cold air through a window at night, and they’re perfect for that task. The power supply unit comes with a relatively long cable, but for my situation I’ve opted to use an additional 33 ft. DC extension cable that I purchased separately. This allows me to keep the fan controller in a more easily accessible location.The fans themselves seem to be fairly well built, and they’re held together with metal brackets between each individual fan. The grills on my fans are metal, just like the ones shown in the product images. The quality seems reasonable, and I think they’ll hold up over time. The speed controller is rather lightweight and cheap feeling, and I’m not sure how well it’s constructed internally. Nevertheless it does work properly, and it offers a good range of control for the fans. It doesn’t get hot or make any worrying noises, so that’s a good sign.I’ll be interested to see how well these fans hold up after long term use. Right now I’m planning to use them during the winter months to bring cool air into a room with multiple computers. I’d recommend these fans.

Good enough!
The fans are just strong enough for what I’m using them as. They are replacing evap fans inside a soda machine so when looking for replacements I really didn’t want Stone Age tech shaded pole motors in there again so I found these. At full blast they will do. Not loud at all. They will be running for 24/7 365 so Hopefully they last for years in refrigeration equipment.

It’s quiet … and yet, very powerful
I purchased this to help with keeping my computer system cool on a budget. Being that I keep the computer on and rarely reboot, it was important to ensure the rest of the components on the device stay cool. I had this for 2 years running strong and never had any issues. Granted 2 years came and went, but I can safely say I can purchase another and know it will last a long while. Definitely worth it.

Makes a excellent small window fan.
I have a small kitchen window that I like to keep a small exhaust fan in. I used to buy those three fan jobs that would gunk up, be impossible to clean then die. These fans are super easy to clean. They also move the air like nobody’s business! I love the variable speed control. At the highest speed they can be a bit noisy but nothing you cannot live with when you need good air movement. Another plus is they are very portable. You can move it around anywhere you need them for just about any purpose. Great item for the price and I expect they will last a while if maintained properly.

great for cooling graphics cards

Worked perfect for cooling down a 6’x4′ dog kennel.
I don’t think there anything about this product that I dislike. Fans are just like basic PC fans, but the plastic frame is not cheap, the motors are brushless, and the dual ball bearing make them run so quiet.I have to build my own kennels as my puppies need one that they can fit in together, yet it can’t be too big or else they use the restroom in it.This last one I built with doubled up 1/2″ plywood, I foamed the top, front and backsides in an effort to keep the cool air inside.The plan was to have some holes in the back and a very open gate like door to make sure there was plenty of airflow. Plasi glass on the sides for light and a slightly slanted roof for rain runoff.The whole thing rolls easily on 4″ casters and can be used inside or outside (recommended under a shaded area.)Unfortunately I couldn’t find the right size gate when the time came! I built a door out of fence wire and mesh, but my dogs chewed it up within 2 visits. They really love to chew on things when left alone.Anyways, I ended up sealing off the door with more wood, and now the thing traps way too much heat! Indoors it’s burning up inside.I bought 2 of these fans for a push/pull setup and on their lowest setting it’s whisper quiet, and yet when I crawled into the kennel it was nice and cool.Highly recommended, good quality, easy to install

I bought this to add a fan to my entertainment unit. I moved my Xbox Series X inside the cabinet and they fan set at 40% keeps the cabinet cool. Got a smart plug to turn it on.Liked this fan so much I bought a second for another problem. Window fans cost to much money IMO. We get no breeze on our bedroom window. I used the legs that come with the fan to stand up and suck the air from outside. Keeps the air fresh at about 60% fan speed and is not noisy enough to keep me up.

Installed this to circulate air within a cabinet. Unit was set to turned on for 2-3 hours a day only. The fan became unbearably noisy after only 6 months.
