Great ventilation fan. I use a pair (intake and exhaust) for my ‘server' closet. Install is very easy and it comes with a great plastIc template to use for the cutout. So much better than paper templates. A few minor complaints:- the power cable that can be used to connect two units together is to short unless the exhaust and intake are on the same surface- finding compatible fans that are quieter is not as simple as you may think due to the specs- having two a separate models for intake and exhaust is just silly. The fans are just reversed in the housing and a switch would have been better- I went through multiple units to find a pair with decently quiet fans because there is a lot of variability between units

Fairly easy to install if you use the template that comes with it. The temperature probe cable could do with being a few feet longer since this is a register plate for a wall or door, extra length would help get the probe closer to the components being cooled

I measured 48dB at 1m away on speed 4/6. Definitely not as quiet as claimed. I was hoping to connect a second S-series unit, as shown in the manual linked to in the item's description, to push more air at a lower speed/noise level. But after calling support I found out those expansion modules were never manufactured and never will be.

I mounted this in the ceiling of an AV closet. Not the typical application but the door has plenty of gap at the bottom for intake and I needed to vent out the ceiling into the attic space. Works great, love being able to adjust the temp setting and spread. It's quiet unless you have to run it on the highest setting, then you can hear it. I'm fortunate it only needs to run at level 1 and sometimes 2. I have it set to increase fan speed every 2 degrees.For those having trouble with the settings and at what temperature it kicks on at, read the manual. You have it in the wrong mode for what you want.

Moved all of my electronics into a closet and didn't realize how hot it would be. These fans looked like the perfect solution. I ordered the intake, and also a exhaust. Super easy to install and they look really nice as well. They could be a little bit more quiet on the max setting but for the most part they're not super noticeable. I've seen people post about replacing the fans with higher quality lower noise fans and I considered it but it's not bad enough to warrant that unless you're really producing a lot of heat because the automatic mode throttles down the fans when full power isn't necessary based on the thermostat reading. The one gripe I do have is the length of the cable to connect the fans together if you buy more than one you can have a master/slave situation so they work in conjunction. My closet was a little big so the wire was too short to make the connection. If you just use one at the top of your door and one on the bottom it should be more than fine. Other than that I'm happy with 2 months of constant use no issues at all.

great packaging easy to install.

Once again i like both the exhaust and intake. They both work very well and do what the description says.
