AC Infinity AIRPLATE S9, Quiet Cooling Fan System 18" with Speed Control, for Home Theater AV Cabinet Cooling

AC Infinity has always done right by me and this is no exception. I bought this fan because I installed a mini fridge in a kitchen cabinet. I had drilled out some ventilation holes but they weren't doing enough to get the fridge to work properly. I installed this fan and it did the trick. The quality of their products is second to none. Even the packaging gives you a feeling of quality and it's just cardboard. The product itself looks great and works just as described. It comes with a template to cut out any of the wall or cabinet where you are installing it. The fans run ultra quiet and are very smooth. It comes with a USB or power adapter. I opted for the power adapter to make sure that it was getting the correct amount of power to make sure that it was working as it needed to. I have the fan on high and you can't hear it at all. Moves plenty enough air for my needs. There aren't any cons to this product. The price is extremely reasonable so don't even bother looking anywhere else.

Bought this solidly built fan kit to cut down on heat build up inside an A/V equipment cabinet that houses a 5.1 receiver and DVD player. Ordered using standard (free) shipping and received in 3 days, Unit is well packaged with good instructions for mounting. Clear plastic template for cutting the mounting hole and drilling the mounting screw holes is included-- a thoughtful touch. Installation was straight forward. I mounted the fan near the top back of the cabinet facing out to pull the hot air out. Existing openings allow the fan to pull cool air in from the front/bottom of cabinet. If the cabinet was sealed tighter, I would buy a 2nd kit, use the USB daisy chain to power it, and mount it facing in on the bottom of the cabinet to really move some air through. The only challenge was installing by myself: How to turn a screwdriver on mounting screws outside the cabinet at the same time as holding a pair of pliers on the mounting screw nuts on the inside of the cabinet?! A pair of vise grips locked on the nuts held them in place so I could tighten the screws from outside, thankfully. Otherwise, you may need a 2nd person for a few minutes. Fan can be powered either by USB or AC power. Fan also has a 2nd, short USB "dongle" for daisy-chaining additional fans: Another thoughtful idea. I plugged the fan into the switched AC outlet on my receiver, so the fan starts automatically when the receiver is powered up. Fan also has an easily removed foam filter. Kudos for a well thought out, well built unit. Most importantly, the fan keeps things cool-- even with both the receiver and DVD player running. With the sound off on the receiver, I can just about hear the fan if I put my head right by the open cabinet door. With the doors closed and with the sound on, there is no discernable noise from the fan. I'll be buying another for cooling a computer enclosed in a cabinet in my office. Highly recommended.

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.

Perfect for my use case - as in intake fan for an enclosed networking closet! Arrived very well packaged and installation was incredibly easy. It seems to be delivering the advertised CFM and is keeping the enclosure cool. No vibration & very quiet, not to mention the plastic they used for the housing is very high quality. Will be buying again for future projects!

Installation was straightforward. I used this to vent my gaming computer out of the side of my desk in order to reduce the amount of hot air blowing on me from the computer. I used an oscillating tool/saw to cut the hole out of my office desk. A few things: The CFM is just okay, but the fan is quiet. There are some weird harmonics the fan puts out, which are mostly not noticeable when the computer is running. I plugged mine into the back of my PC and set my BIOS to de-energize the USB ports when the computer is in "soft off" mode. This way, the fan only runs when the computer is on. All in all, it does measurably reduce the temperature of the area at the front of my desk where my arms are placed while gaming. It's only a few degrees, but the perceived cooling of cooler air passing over me is by far the most noticeable part. It's built well; the quality is good.

Wonderful product! The first thing you notice about this product is the professional care this company takes with shipping its products to you. It's Apple-level of thought in packaging here. Once you open the product the instructions are very easy to read and understand. The fan comes with a plastic template for use when you cut into your stand (or wherever it's going) which is much better than paper templates I've gotten with other types of products. The installation in my entertainment center was easy with the right tools. It hooks up to its own power supply and it's a nice bonus that the fan itself contains USB power outlets and plug-type outlets for other items to plug into and be powered by! Once installed the adjustable fan speed makes the noise level from a level of inaudible to somewhat audible in a quiet room. Once you have your sound system or TV going you won't hear the fan even on the highest setting. One thing to note about my particular installation. I installed this on the back of my entertainment center as a set-it-and-forget-it type of install. The only issue here is the speed and power controls are on the back of the fan unit and thus, hidden from my view on the back. This won't be an issue if you plan on installing the fan on the side of a unit or cabinet but I did take a picture of the back of the power unit for my own reference in case I ever have to reach behind the unit and change the settings. Once I dialed in the setting I wanted, however, I haven't had a need to adjust anything. As to the effectiveness of the fan? It's great! My AV receiver sits in the entertainment stand my wife picked out. I mentioned that because she picked out a beautiful piece of furniture for the stand but it has zero ventilation as a unit. Obviously an AV receiver generates a LOT of heat and cannot sit in a closed box without ventilation. This fan has perfectly performed and I can attest with the help of my laser thermometer that the inside of the closed box stays nice and cool at all times! I cannot recommend this unit to you more highly. In fact, I've gone on to purchase three more smaller fans from this same company (for use in the same entertainment stand for my PS5 that sits in a smaller section of the entertainment stand). They work perfectly as well. Very highly recommended!

5 stars to start. Looks great and professional Easy install. Comes with all needed hardware for thruhole mount or wood screw mount. Comes with a clear template/gasket to trace the necessary opening. Instructions state to reverse airflow, you need to disassemble and flip the fan around. It would be nice to reverse with a switch, but probably based on the fan electronics. VERY quiet. We shall see about durability. Overall it’s a great solution instead of buying all the pieces yourself and building it.

Impressive quality. Works as, or better than expected. I installed this in a kitchen cabinet for a water purifier and ice maker that were getting hot and not working correctly. It's fairly easy to install with a multi-tool and seems to have done the job. Keeps it about 10-15 degrees cooler with the automatic thermostat switch.
