AC Infinity AIRFRAME T7-N White, High-Airflow Cooling Fan System 400mm, Intake Airflow, for AV Equipment Rooms, Closets, and Enclosures, 16-Inch

Super high quality. Lots of airflow with not much noise. Installed the airframe inside my entertainment closet wall which vents into the evening room. Intake air will passively come in below the closet door. The programming ability with the included buffer feature is highly convenient. Be sure to order the correct intake/exhaust airframe for your application. $150 well spent (airframe and white vent grille) I highly recommend AC Infinity products, the quality is superb and the warranty is definitely a plus.

Basically this unit will push air but it will not make any size of space any cooler. With that said, I’m sure others might find it worth purchasing.

Fantastic product, reasonable noise for the volume of air it moves. Wish I had purchased one with air flow in the other direction

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

(Updated 2/7/2026) I've lowered my rating because of how much of a nuisance this fan has become. The controller logic for SMART mode needs attention. Regardless of what temperature I set my system to, it more often than not will reach a point where it is speeding up and slowing down constantly when approaching a temperature that is a fan speed transition. Having this running constantly is not an issue - it becomes white noise and gets tuned out - but the constant changing in fan speeds draws attention to it and makes it annoying. AC Infinity makes so many cool products especially geared toward tech-forward people. They really need to step up to the plate and come up with a smarter solution here.
