Great. No problems. Installed to provide extra airflow for vivariums.

Needed to replace some dead fans in an LED Sign, these fans will work great as replacements...

We use hundreds of these for our dental cabinets. Great fans and great customer service.

This is a great fan and Coolerguys.com are always a joy to work with.

The USB fan works great. I'm using it to cool a battery bank that I made. I do plan on buying more of these fans soon, as I plan on makin more units
