AC Infinity AIRPLATE S1, Quiet Cooling Fan System 4" with Speed Control, for Home Theater AV Cabinets

I don't write reviews for every product I purchase on Amazon, but once in a while you get one that exceeds expectations. These fans are extremely well built and well packaged, as soon as you take it out of the box you can feel and see the quality in fit, finish, and attention to detail. My wife was getting irritated that I took over her "coffee station" with my networking equipment (4G Booster, NAS, Router, Switch, and Raspberry Pi). So I tossed them into the storage of the mini kitchenette, I quickly realized that all that equipment runs HOT in a confined area so I went to Amazon. I found these fans, and albeit they are a bit expensive, you get what you pay for. Let me say that again, you get what you pay for. Buy once and cry once. My network "cabinet" not only looks awesome with the air vents on it (the external aesthetics really are a great design), my equipment runs colder than it did out in the open. Plus, my wife is (slighly) less irritated. To wrap it up, you get function AND form, the price point is steep, especially for two fans (one set to push, one set to pull). There are cheaper ways to achieve this function but nothing can match the form, oh did I mention that they are nearly silent, we also have a small air purifier in the room and you cant' hear the fans running whatsoever while on Medium which is MORE than enough flow for my small area. I also have them powered by the USBS ports on the the Raspberry Pi. Oh, did i mention I have a huge APS UPC in the lower portion of the cabinet, so this way as long as the Pi is running (which it will if anything in there is running) the fans get power from the backup battery. Very happy with this product, not excited about price, but it is worth it.

We started having a lot of issues with the cable box/media hub overheating thanks to the pretty. but electronics ventilation unfriendly, TV stand at my dad's place. Installation was easy and straightforward. I recommend pre-planning before cutting the holes. That's no big deal with a drill and a small hand saw, as long as you use the included templates and don't rush.We installed two of these fans (one in each cabinet compartment) plus the AC Infinity CONTROLLER 2 thermostat and speed control unit, with the temperature probe set up in the compartment that has the equipment that is always on (cable box and media hub/router). Having set up DIY cooling systems years ago using parts from electronics stores, I have to say that using USB interface to chain the fans is a nice design choice that eases installation significantly. Total install time for the 2 fans + temperature controller was about 2 hours, but I was using manual hand tools (no power tools except a Dremel sander for a little fine tuning) and had an 80lb Labrador 'helping'.Based on the size of the fans and prior experience with cabinet cooling systems, I as expecting them to move less air and produce more noise. So far, they've performed admirably in cooling the cabinet and I usually can't hear them at all. The internal fan on the cable box is louder. We debated setting up extra fans as intakes before the order arrived, but that hasn't been necessary.

I plan to mount this onto the base bezel of a Pelican case of electronics that will generate too much heat. I have not done so or used it much, but out of the box I'm blown away by the quality of this product. Because they don't supply any technical information whatsoever, and Q&A and reviews on here are just all over the place (wrong information, people talking that should not, etc.), I wanted to immediately share first impressions and the power measurements and testing I just did.Firstly, it does not blow a ton of air, and I have no way to measure that. They state 26cfm, I would assume this is using their "boost" adapter (it just puts out 6.4V instead of 5V) and on the "high" setting. At this max output, it makes enough noise that you can hear it. It is REALLY quite quiet. The reports from people that it is "loud" must be in the context of a home theater, you would indeed hear it during quiet parts of a show. But it is NOT loud. But, at settings other than high, or not using their power supply, I could not really hear it at all.Ok, I also have detailed power measurements for those that need this:Any 5V USB Power SupplyLO: 98mA, or 489mWMED: 124mA, or 620mWHIGH: 157mA, or 789mW"Boost" Supply (included)LO: 124mA, or 786mWMED: 156mA, or 1WHIGH: 198mA, or 1.27WI hope this helps folks, this is an excellent product and very low power, I think. Please ignore the ignorant and snarky other information people have posted on here, and no, none of this is posted by the manufacturer here, or anywhere else.
