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

I bought one 4" (80mm) AC Infinity fan without the controller to cool the enclosed CPU section of my desk. I have a desktop computer housed in the desk CPU enclosure that puts off a substantial amount of heat and within 1-2 hours, I measured the temperature inside the desk CPU enclosure to be around 84F. Electronic components typically don't like being run in temperatures higher than 85F and will have a reduced lifespan if they are run hotter than 85F. My desk already had a preexisting opening from under the desk surface (where my feet go) to the top of the CPU enclosure. This opening was designed to allow monitor cables to be run from the top of the desk into the CPU compartment and measured 3.9" x 6.9". I installed the fan (blowing out) at the top of the opening and closed off the remaining bottom portion with a plate. The AC Infinity fan runs off an integrated USB port located on the back of my computer and (seemingly without effort) keeps the desk CPU enclosure at almost room temperature (plus maybe 1-2 degrees). Note: I did NOT have to use the USB "turbo" converter that came with the fan. I also did not drill any new ventilation holes into the desk CPU enclosure for air intake. It would appear that the natural 1mm cracks around the closed doors on both sides of the desk CPU enclosure are sufficient for allowing room temperature air to flow into the desk CPU enclosure. The really cool thing (no pun intended :)) is that when the computer goes to sleep, it not only stops producing heat but ALSO shuts down the integrated USB port which in turn shuts off the AC Infinity fan. It is a perfect system that negates the need for the optional AC Infinity fan controller. The AC Infinity fan runs so quietly that in a dead silent room, I can't tell if the slight hum I hear is from the AC Infinity fan or the louder fan located in my computer's power supply within the cabinet. I HIGHLY recommend this fan for this application! I have also used the AC Infinity 6" (120mm) fans in my much larger home entertainment cabinets and they also perform very well and very quietly. Update: After writing this review, I tried running the fan on the low setting and the temperature inside the CPU enclosure did begin to (very slowly) creep up. Also, on the low setting, the slight hum disappears (to my ears anyway). So, the fan running on high setting does add to the hum. I'm going to watch to see if on the low fan setting the temp stops rising at some point. If not, I'll run the fan on the high setting and not worry about it. I still don't need to use the "turbo" wall USB adapter that claims a 25% increase of airflow. But, it is nice to know I have that option if I add heat producing components to my desk's CPU enclosure.

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.

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 Supply LO: 98mA, or 489mW MED: 124mA, or 620mW HIGH: 157mA, or 789mW "Boost" Supply (included) LO: 124mA, or 786mW MED: 156mA, or 1W HIGH: 198mA, or 1.27W I 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.

I ordered this fan to add to my battery spot welder as the internals get very hot and cause electrical component issues. It is a flush mount fan, therefore I had to make a spacer so that the fan does not hit any internal components. High fan speed is a little slower than I expected, but again, I don't think this is to be used as a velocity fan, but more of an air circulation fan. The 2 styles of USB connections don't seem well placed, or not useful ( in my application) but again these types of power connections may work well when used in their true purpose as entertainment cabinet fans in conjunction with other electrical devices. Very happy with my little fan!

Bought 2 along with a temperature probe to keep a media cabinet cool that houses a SKY box and router. The fans are well packaged and look quality. Templates included for fitting, along with all necessary screws. Reversing the fans is also easy (I've one for inflow, and the 2nd for outflow), and both fans and probe are connected to a single power outlet. On low, the fans cannot be heard, and even on high you would struggle to hear them above other background or TV noises. Very impressed.

Unsere Wohnwand ist mittlerweile, neben anderen Geräten, mit knapp verbautem 4k-Fernseher und Mini-PC bestückt - da kommt schon einiges an Wärme zusammen. Um die Geräte etwas zu entlasten, habe ich nun einen Lüfter gesucht; zuerst dachte ich an PC-Lüfter, aber dann habe ich diesen kleinen Lüfter entdeckt. Was soll ich sagen - bereits beim Auspacken war ich begeistert! Qualität macht sich oft in kleinen Details bemerkbar: Sorgfältig verpackt, perfekt geschützt und sortiert, ohne übertriebenen (Plastik-)Müll. Eine Beschreibung, die in einem kompaktem Heftchen und in sauberen Englisch sehr übersichtlich und gut bebildert keine Fragen offen lässt - etwa, wie man die Gebläserichtung von Saug auf Druck umstellt. Es liegt sämtliches Montagematerial bei - lange Gewindeschrauben und Muttern, für den Verbau in dickeren Panelen, sowie kleine Spanplattenschrauben für dünnere Rückwände. Eine Kunststoff-Schablone zum Positionieren und Anzeichen für das saubere Ausschneiden. Kurzum, man hat wirklich an alles gedacht. Und der Lüfter selbst ist in einem stabilen Gehäuse mit einer Front aus gebürstetem eloxierten Aluminium verbaut, kann mittels beiliegendem USB-Netzteil betrieben werden, oder direkt an einem USB-Port angeschlossen werden. Dies ist bei uns der Fall, er hängt am TV, und schaltet sich somit immer ein, sobalt der Fernseher läuft. Das Laufgeräusch ist dezent, er Ventilator läuft sehr ruhig auf mittlerer Stärke. Lediglich auf "High" ist er schon etwas lauter, bedingt durch die höhere Stromungsgeschwindigkeit, daher ist bei uns "Medium" eingestellt. Genial ist auch die Möglichkeit, den Lüfter zusammen mit anderen Lüftern (bis zu 6 insges.) und einer Steuerungseinheit temperaturgeregelt betreiben zu können - einfach zusammenstecken (Plug&Play). Fazit: schönes Design, hochwertige Verarbeitung, erfüllt den Zweck und ist erweiterbar - ich würde ihn wieder kaufen, und werde sicher bei zukünftigen Projekten wieder darauf zurückkommen. Allerdings dann zumindest die größere Variante, oder gleich in Doppel-Ausführung: mehr Luftdurchsatz bei geringerer Strömungsgeschwindigkeit = leiserer Betrieb und (noch) bessere Kühlleistung.

Een heel stille ventilator, helaas wel met een usb adapter, waarvan de geleverde stekker een VS. format heeft. Het verschepen vanuit VS. duurde wel heel erg lang. Verder heb ik hem nog niet lang gebruikt dus qua kwaliteit/duurzaamheid kan ik niets van zeggen. De ventilator wordt volledig compleet met schroeven en zaag-mal geleverd. Qua milieu oogpunt valt er ook nog wel het een en ander te verbeteren, o.a veel plasticzakjes in plasticzakjes. En nu dus een onbruikbaare adapter...

Great product of noticeably high quality. Easy install and all mounting accessories were included. I'm in Australia and AU conversion plugs were also included in the packaging which was appreciated. Daisy chain feature is a nice touch so that both fans can function from one power source. Have mine both set to medium speed and cannot hear them at all while operating. My tech cabinet is on average 10-12 degrees C lower since installing the fans so very happy with the outcome! They aren't the cheapest, but you get what you pay for and these are quality fans.
