They are so quiet you barely notice them being on. They move some serious air so they keep your electrical components cool. I installed them on a 6 cup turner I built for my wife and it sufficiently keeps the motors cool

Didn't need this for cooling so no comment there. Needed something that draws 30watts for vacuum auto switch actuation (dust collection system). This setup allows me to connect a rocker switch to these fans, to allow for use of the vacuum without having to power on the table saw or router (which is what the vac auto switch does). Fans did the trick! Solid construction.

The media could not be loaded. I brought the other fans from this company without reading a review and those sound like being in a data center, it was like I was close to a small jet engine but these fans are quiet with a very nice wind speed. These are good for small to midsize cabinet.

This product was delivered on time and came well packed and in great condition considering that its a bulky and heavy. It is built with sturdy material and is not flimsy metal material.I had more then enough room for the equipment I placed in it ( 1u Meraki Switch, 2u Dell Switch, 2u POE Switch, Cable Box in the back). The only reason I gave it 4 instead of 5 stars was due to a few personal preferences that I would have preferred with the product.
1. Wall Screws to mount the unit, which I didn't realize or plan out when ordering the product.
2. The case fans to move air within the unit were ordered separately and a pain to put in and could have been in place already with the added appropriate cost to avoid additional headache, or offer a unit with them prebuilt which I didnt see here.

I definitely would recommend this for purchase to others and will purchase additional units for future projects. Its light enough and airy for air flow and temperature related issues.

Mounted these into a kitchen base cabinet in order to keep under cabinet beverage refrigerator and ice maker cooler. Moves lots of air and very quiet. Thumbs up!!
