These are exactly what I needed....and didn't know it! hahaha. I built a beautiful built in cabinet in the living room, didn't want the Internet Appliances and gaming consoles where everyone could see it. However I would have to leave the cabinet door open anytime I used a game console, otherwise it would heat up ALOT. Now that the Fans and thermostats are installed, I LOVE that the fans will automatically turn on when it starts to heat up inside the cabinet. They are QUIET and look GREAT! Couldn't be happier about this purchase!

Definitely worth the purchase price. Works exceptionally well, would have liked a mount for the temp probe though!

I installed this in the door of a half sized media closet where I have a NAS, Router, and a few other electronics components. It doesn't get real hot but I do plan on installing more so this was more looking ahead.Our of the box, really good quality. Sturdy metal face plates. Included templates to cut door holes which worked perfectly. Set up was very easy. Some extra hardware allows various install options. I fiddled with how to run the power cables and thermostat transducer since the fans are mounted on a door but figured it out. The rest is plug and play.There's several cooling modes to choose from. I tried them all and ended up using the incremental speed mode. At 80F fan comes on in slow speed. As temp increases, speed increases, and will get to high speed at 100F. Temp is adjustable but this works for the current heat load. Closet usually runs in low to mid 70's but it's gone up to 80F on a few occasions. Slow speed kicked in and cooled it back to mid-70's quickly where it shuts off. I think my Setup could accommodate a lot more heat load.The fans are louder than I thought even after reading the many reviews noting that. They're basically CPU cabinet type fans you can install anywhere. Although they do seem louder. Although that could be due to where they're installed. For my application it's no concern since the closet is out of the way. Could be a concern if installed in the back of a stereo cabinet or something. There may be some tricks you could use for sound dampening.Definitely good quality with good features. Just make sure you consider the noise when purchasing.

This system is a great addition to my desk to help move more air through. It gets pretty hot when I'm working or playing games so I was looking for something just like this. The install was easy I just didn't do a good job on my layout so the fan covers overlap the controller just a bit. I might take it to work and put it on the milling machine to shave the edges. Functionally, it is great though. I have run them on smart and the controller adjust the fan speed the closer it gets to the temp I have set.

Installed these into a new entertainment center where all components are behind closed doors. The included templates are very helpful and made installation a breeze.

it ran for a while and then one of the fans quit working-I've reached out and tried calling several times and always get a voicemail and I'm told to email or just chat and the chat doesn't work as well-So the fan is still broken- worked good when it worked for The first few months and then it died.Sadly the company does not reply to emails or answers their phone.

Comes on when it's supposed to, does what it's supposed to do, then turns off until it's needed again. A little on the loud side, but nothing overly distracting. Easy to install and set up, and protects my investments.

I installed these in an TV entertainment center where we have our receiver. Very clean looking through the glass behind the receiver that looks like it came with the furniture. I'll buy these again if I need a similar solution.

This product is very high quality and is packaged in a matching black stereo component-style box. The components are high-quality too, held together with screws, not glue. This also makes the fans flexible for different installations. I adapted this kit to help keep our solar power inverter cool when the inside of the garage heats up on hot days. It works really well! The temperature probe gradually ramps the fans up in Smart mode, as the inverter temperature rises, blowing air across the heat sinks on the back of the inverter. This relatively small investment will extend the life of our inverter and optimize our daily solar production. Very cool!

Overall I'm very happy with this unit. Easy to install given the right tools. Good features and easy to use. Very cool touch to my wire-managed desk!

Two strikeouts. I tested the first set of fans before I cut holes in my new expensive cabinetry (Thankfully). One fan was great. The other was buzzing with a high pitch annoying sound. Returned and replaced. The replacement had an even louder buzzing noise in one fan... and arrived with the direction already reversed!!! This means someone opened up the fan and swapped directions in the housing. The seller sent me a returned item as a replacement. WTF

This is something that everyone should use because of the need to keep the temperatures down on your AVR receiver.

A friend gave me an equipment rack for my home network and storage gear but he said the fans on it are loud. Before installing it I replaced those fans with a pair from AC Infinity. I love them. I set the temp and adjusted everything without any issue. It was also so easy, I didn't have to flex my brain to do it.

A little tedious to install, but they do provide a nice template for cutting the holes. You have to get to know it a little with smart mode and when you want them to come on. Overall very satisfied with this setup.

Solid product for sure. We have a ice machine under our island and I wanted to make sure it had the best ventilation possible. If your looking for a solution to keep your items running at a cool temp this is for you. Love the smart feature as well.

This fan system is by far the coolest thing ever. I use it in my sound booth for recording vocals to keep it comfortable. I built a zig zag insulated 4duct box (look up sound damping insulation box on YouTube) on the the side and it is wisper quiet when on. Plus the mini thermostat that comes with it is always an eye catcher. Good investment for anyone looking to move air quietly and effectively

My 2nd AC set and they work great. My first has been up and running for 6 years now. Nonstop. No issues.

Very easy to set up and install. Noose level is very acceptable. Great for keeping my cabinet cool.

These fans look fantastic and definitely help keep the cabinet cool. I'm planning a second set for another cabinet already.In Smart mode, the fan may cycle around your set temp too frequently (another reviewer commented about this and I noticed it too). The fans are quiet on the lowest setting, but they aren't silent, so when I set my controller to 80F, the fans would kick on and off several times a minute while the temp bounced between 79F and 80F. When the AV components are on, the temp is typically high enough to keep the fans running, but when they're in standby there's just enough heat to make the fans cycle constantly. This is annoying if you're using the living room for reading but not watching TV, for example. The solution is to stick with Auto mode.In Auto mode, there's a cycle interval, so the fans come on at 80F and then turn off at 76F or 78F depending on how you set the interval, so the fans don't cycle quite as frequently. If you're sensitive to the noise of the fans, this is the better setting to use and works more like your home thermostat does.

Works great, I use the two fans on the top of my media console to pull hot air out with two vents on the bottom to let cool air in. Keeps my amp, PS4, and Samsung One Connect Box cool. Even at full speed the fans barely make any noise. Really like that the temperature prove can turn the fans on and off as needed.
