AC Infinity AIRPLATE S1, Quiet Cooling Fan System 10cm with Speed Control, for Home Theater AV Cabinet Cooling, 4-Inch

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.

I don’t usually write reviews but this is a fantastic product beautifully made with every detail really carefully considered. Quality is faultless down to excellent instructions and a couple of extra nuts for each size in the packets in case you drop one which is all to easy to do. You really get the impression when you're fitting these fans that someone who has actually fitted them put this kit together. The templates are rigid plastic, there are screws and bolts to suit a timber cabinet install or a rack install as I did and you can easily reverse one or both of the fans to blow in rather than extract. I reversed one so cold air is blown into the air at the bottom and hot air is extracted at the top. You can even expand the kit to four fans if you want of one controller. I contacted infinity's tech support prior to purchase to check on whether settings are retained after a power outage and they confirmed immediately on their chat that they were. The UI is easy and well thought out. It’s a real breath of fresh air to receive a premium designed and beautifully made product at a great price (check how expensive these have been at Amazon in the past with a price checker), so much so I found myself looking round the house to find other opportunities to install them. They have reduced the rack temperature and maintained it constantly. See my pic from the router’s temperature monitoring. This kit was exactly what I was looking for and exceeded my expectations in every aspect. Carefully thought out, beautifully designed, and meticulously manufactured. Thanks Infinity- I’m really impressed!!! Would give this 10 stars if I could!

I purchased two Airplate S7 units to fit into a cupboard that I was using to house my two NAS units. The cupboard was getting very warm prior to installing the S7s but now it is always nice and cool. Very easy to fit and extremely quiet. This small cupboard is my lounge and the noise from the fans is practically non-existent (I have them running at the highest speed).

This is a well built and designed product, easy to fit with the included plastic templates for the fans and controller. As expected though, the fans are relatively noisy. It’s not a surprise at this price point as a pair of decent fans are half the cost of this unit. I wish manufacturers would sell these without fans so you can supply your own. I ended up buying 2x Noctua NF-A12x25 5V. It’s important you get the 5V version and non PWM. With these fitted, noise levels were dramatically decreased. I measured before and after with the dB meter on top of the cabinet the fans were in. Ambient noise level 35.4 dBA Old fans: Min speed - 38.4 dBA Max speed - 46 dBA Noctua fans: Min speed - 35.4 dBA Max speed - 45.3 dBA As you can see the Noctua fans are inaudible at the lowest speed. It’s also worth noting that the noise is a different tone that is easy to ignore, as opposed to the higher pitched tones present on the standard fans. The Noctua fans spin faster at the max setting, so this accounts for the noise levels being closer to the standard fans, even so, they’re still quieter and it’s unlikely you’d want, or need those speeds, without some serious heat issues anyway. I’d recommend the installation of fine mesh filters to stop the dust affecting the fans and the inlet sucking dust into your cabinet. When the fans are off there is a high pitched tone from the power supply but I can’t hear this when behind the cabinet. Worth noting though if you have this plugged in somewhere close and exposed. Edit: The power supply actually died after a couple of weeks, which accounts for the high pitched tone. AC Infinity is a US company. Their website doesn't actually list these as having the option for a UK plug, but it was labelled AC infinity. Rather than having to remove everything from my cabinet and send back, I sourced a better quality, identical spec power supply locally. For reference you would need a 2A (or higher) 6.5V (7V Max according to specs) AC adapter with a 2.1mm x 5.5mm jack. Since fitting the new one it has been absolutely fine. I may have just got unlucky, but worth factoring in. In conclusion your money is buying a good looking frame, great installation instructions with plastic templates and a quality fan controller. In my mind this is still worth the purchase cost, just factor in that you may want to replace the fans and need to replace the ac adapter.

Using it on my homebuilt server rack to force air through from the front of the disk storage (12 bays so generates quite a bit of heat) and its been great this summer. Previously the inbuilt fans on the DAS (direct attached storage) would ramp up from the default slowest of 1, to 2 or 3 when we had hot days. With this driving a gentle feed of air in addition it's stayed at 1 even on the hottest days, and the additional noise is only very slightly detectable, whereas the DAS going up to its 2nd speed is over twice the db of level 1. Great addition to the home server setup.

All you have to do is open the package to know it's a high quality product. You know how you get stuff on Amazon and it's basically loose in a box with no instructions, well this is the opposite! The box is worth saving. Haven't installed the Fan yet as my project to wall mount it to circulate air from a gas fireplace isn't ready yet. Tested it and it works very well, and very quite. Removed the faceplate because I need to paint it. It's actually a shame because it has a brushed aluminum black anodized finish which is perfect. Faceplate grills are rubber mounted to reduce noise, just another example of quality.

Good performance. Been using this for several projects.

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 have a few of AC Infinity products for ventilation of AV equipment. I would recommend any of their products

This is a very reliable product, easy to set up. The fans can be separated from their frame to reverse their direction to push or pull air as needed. You can use the control buttons to configure this system in many ways to suit different scenarios. It includes a printed colour manual that is easy to read. I am using it to cool an AV rack housed in a cupboard. I set it to adjust fan speed based on temperature, and to beep if it exceeds a specific temperature. The power adaptor included in the box has a US plug.
