Review: Absolutely perfect product for my needs! - Absolutely love this product. So I currently have a large corner desk, one end of the desk is a cupboard which acts as the support to hold up the desk. This cupboard was evidently intended to house a computer as there's a cutout in the thin board at the back of the cupboard however, the temperature gets quite toasty in there so for a few months I used it just for my tool boxes. I then built a small media server/file server to run Plex and uTorrent 24/7 as well as handle backups for all my devices. I decided I wouldn't need physical access to this device often and since I wanted to leave it running 24/7 it had to go somewhere quiet and non-disruptive. So I decided to place it in this cupboard, I also put my xbox one and xbox 360 in there too, as well as my network switch and my new Linksys WRT1200AC router. So it's quite a packed cupboard but gives me easy access to the devices if I need to, without taking up precious desk space and causing an eye sore and an ear sore. The biggest dilemma with this setup was the heat build up in this cupboard. With only a small gap above the cupboard door and the small hole in the rear for cables, it didn't take long to heat up. Enter the AC Infinity AIRPLATE S7. I had considered doing a bit of a DIY job and simply re-purposing 2 computer fans and a mesh filter of some description and wiring them up and mounting them on the back of my cupboard but it all seemed a bit too much work as I'm not the best when it comes to wood work and soldering so I began hunting, I found the AC Infinity and it suited perfectly. It arrived with a small paper template to guide me where to cut and drill holes to install it, the fans etc. came pre-assembled so it was a simple case of drilling the holes and the cutout and popping it in, then plugging it in (via the USB power cable), switching it on and away it went. I plugged it into my xbox one initially since that was the biggest cause of heat so whenever the xbox turned on, the fans turned on too, however I decided I wanted to keep the cupboard extra cool for all my devices so I plugged it into my media server and It's been left on for over 5 months now without a single hiccup. The cupboard remains cool even with an Xbox One cranked up, a surprisingly warm router, and my media server all packed into a small side cupboard. The fans make short work of it and are nearly impossible to hear when the cupboard door is shut. The rear of the cupboard is just to the side of my bed and I can barely hear the fans, they are absolutely fantastic in terms of noise levels and also manage to shift a great amount of air whilst keeping quiet. I am so very happy with my purchase, if I ever build a small home theater setup, an AC infinity airplate will be at the top of my shopping list to keep everything cool and quiet. For this use I decided to go for the simple USB setup and not the touch screen panel simply because I couldn't be bothered cutting more holes. For my use case, I want it turned on and left on so the small screen was not necessary. However, if I were to build a home theater setup I would definitely grab the screen and mount it on the side of the TV cabinet. Again, cannot praise this product enough. If you've got a cabinet or cupboard, or even a drawer where you keep devices or items that get warm then this product is the one for you. Quiet, power efficient and very effective at cooling. Not to mention cost effective too!
Review: Quiet, effective and quality engineering - Attention Tent Owners This is my third AC infinity product. I have previous purchased two ac infinity intake/outtake exhaust fans which btw are great and still in use one year later. My purchase: Ac infinity dual fan wallplate/airplate with the switch non-controller version. My application: pull cool air from the room into a 3x3 to keep the plants inside at optimal temps. Normally temps inside are acceptable at 80-82 degrees, but in flower I want to get several degrees lower to simulate fall/harvest. Why I needed it? I use an LED that at its highest settings putting off quite a bit of heat into a small space and although a great LED, too big for the space (bigger isn’t always better) so I was having difficulty dialing in temps even in my mostly automated small space. Full disclosure - I’ve purchased more than my fair share of fans over the years from desertcart and other big box retailers. Some I still use, some shelved, others recycled or returned. Rather than setup a proper intake using another ac infinity intake I went ahead and tried fan after fan propped against the side of the tent with the flap open to force cool air in. Btw the inexpensive desertcart basic floor fan pushes a lot of air, but I digress. And This method works, but adds additional noise and light leakage both in and out of the tent (night/day). As you know, this is a problem and will result in confused plants or worse, herms. That said, I’m still lazy, seeking the easiest cheapest way and I’ve been so pleased with my other ac infinity products (I decided on this unit after measuring my tents side mesh window which was close enough) it was an easy decision to take a flyer on this dual fan airplate. This fits my 3x3 bottom mesh vent exceptionally well. I didn’t even have to use the included screws or zip ties that’s how snug it is. Perfect even. I simply used a boxcutter to cut out the mess in my tent and forcefully pushed the plate into place. This admittedly took some extra elbow grease, but once i got it in, I’d say its the middle cup of porridge, just right. This airplate on its highest setting I am able to keep my homes air set to 70-73 and allow for cool fresh air to enter the airplate/tent and force the hot air generated from my LED out of the top. My ac infinity outtake fan is pulling that hot air set on low with a controller (setting 2) through an oversized filter from another company to filter any smell (none) back into this spare bedroom. Added some pics. I opted to go with the non-controller version of the dual fan airplate as I have two other intake/outtake fans (ac infinity) with the controllers and thought it would be overkill. The airplate has a small switch on it with 4 settings. Off, low, medium & high. On high, it’s quiet and mostly unnoticeable and pushes enough air into tent to keep the perfect temps! Surprised me for an airplate that it was able to push as much air in as it does. Pros -perfect size for my application -quiet even on its highest setting -always on feature (using a smart app controlled outlet to turn off and on) -moves more air than expected -great engineering as usual Cons Not sure it’s a con, but it would have been better in white rather than black and without the controller I don’t know if it was possible to push even more air in on possibly higher settings. White was unavailable. That’s it, hope this helped some folks. Thank you AC Infinity

## Questions & Answers

**Q: can you hear the fan, how quiet is it?**
A: Yes you can hear it at every speed, even on the lowest speed.  I have the two-fan 6-inch version (total 12"x6" grille. I'm a LITTLE disappointed but not enough to prevent me from purchasing another of the same for the Receiver area of my AV cabinet. Do NOT expect these fans to be silent.

**Q: How can I control when this turns on and off without having to upgrade to the model with a thermostat? If I plug it into my Yamaha receiver usb output**
A: It has a toggle switch. Manual, but not terrible. If it's plugged into something that you turn on and off, it'll run when that component is turned on.

**Q: Is it better to Mount where the Fan pulls out the Heat from the Cabinet or better to blow Air into Cabinet?**
A: It's better to mount where it will pull the heat OUT, thereby bringing in cooler air unimpeded by other airflow inside the cabinet.  If you blow air into the cabinet, it may not be able to exit as quickly and you would get air blowing back around the inside of the cabinet and impeding airflow into the cabinet.  Think of it his way, if you blow into a paper cup with a fairly small hole in it, you can only "blow" so much air in and the rest comes back out at you. to avoid this potential problem, you will get the maximum airflow through the cabinet by pulling in air that is exhausted out by the fan.

**Q: What is the size of the hole that has to be cut in the cabinet?**
A: The fan comes with a clear plastic template to guide you. Just tape it to the cabinet wall you are mounting the fan onto. The hole is about 5 inches square. The face/lip of the fan is about 5 3/4 inches square. You also must drill 4 holes for the mounting screws - also made easy using the template. For me, it took 10 minutes to hand-saw through the thin, paneling-like board backing of my entertainment cabinet. 10 minutes to mount the fan with 4 screws. It took 2 minutes to plug it into an unused USB port on my amplifier for fan power. Now, my whole 7 component system stays cool. After watching a movie, it took 15 minutes to clean up my mess.

### ⭐⭐⭐⭐⭐ Easy install, reduced temperatures and noise!
*by J***2 on August 17, 2018*

Just got the AC Infinity AIRPLATE T7 w/ Thermostat Control with an AIRPLATE S9 (one for inlet, the other outlet). Used them to convert a closet into a ventilated computer server closet (I was forced to leave the door open all the time and even then it still got to hot). I decided to go this route instead of the hundreds for a 19" rack because in the end it will still be an eyesore to look at and noisy! It's cooling the 3 machines without any problem which run at 100% CPU load 100% of the time. They come in black only so I decided to paint them white to match the door. The design of the system is very simple and very effective. Pros: * Easy install, pre-cut plastic templates included, about 2 hours for all 3 combined (took my time). * Simple cabling design, only 1 power source, daisy chainable should I want to add more. * Solid build quality, look good and they make it easy to replace/upgrade fans. * Noise reduction, no longer have to leave the door open, sure you can still hear noise but much less. Cons: * Included manual is actually really good, however it does miss how to change the brightness level. This is literally the only thing I can find to "complain" about and the answer was only a search away. * Probably a bit on the expensive side, but considering it just works, doesn't phone home and I doubt they sell millions of them (though they should) I'm not complaining. All in all, for me, it turned out to be one of those feel good projects because every thing worked as expected, no hiccups, and a really nice outcome. Rarely will I write a review let alone take pictures, but here you have it. The before (door open), black (factory) and finally in white. Not sure why amazon is flipping the pictures sideways? Updated: I tried to contact support for a simple question about voltages and switching fans and never got a response, however they had no problem asking for me to give another positive review. So I wouldn't say I'm mad, but certainly not happy with their support. At any rate allow me to do their job for them. You CAN upgrade to regular PC fans (standard 120mm) but note that USB power is only 5v and the supplied wall adapter is only 6.5V so your fans wont spin fast. However my question was if it was OK to use a 12v supply. So I took a gamble and have been using a 12v 2a adapter just fine for a couple weeks. I did try a 13v but that was to much and caused the control unit to flash on and off (no good). I did also have to turn down the brightness on the control unit because it was way to bright @ 12v. Anyway, good luck folks, I really like these things!
