Great for powering fans
I got this to power some fans I had harvested from my old computer case before switching to a larger, newer model of the case I was using. Currently I use one of these at work to power a fan to increase airflow and it's been working great since I've bought it last year. The power going through it is consistent based on my measurements and I never heard my fan suddenly speed up or down as well. I plan on eventually ordering more for the other fans I harvested for other projects such as cooling my Nintendo switch or for ventilation purposes. Overall I highly recommend this to people looking to repurpose computer fans.

Nice Build Quality, Inexpensive, Works Flawlessly

It works!
This is a 12v 1 amp plug in adapter to covert 120v AC power. It has a connector for a 3 pin computer fan. I plugged this in and it worked instantly to power a 12v computer fan being used to cool a free standing gateway/nvr device. Soon after, the internal temperature of the device dropped 20 degrees C. This adapter is working fine. It is a bit hard to unplug the fan connector from the adapter’s connector. But this is attributed to the type of connectors being used, which has a tight locking tab that needs to be lifted to unplug. I am pleased with this item.

inconsistent
The cord works, but provides an inconsistent power supply. Great for the price though.

Good for my klipsch ultra cooling on amp
I have a klipsch sound system where there is a cooling fan mod in the amp to keep temps down and save the system. I went and got this as the old setup was failing with a 10yr old stalled fan. I got a noctua 92mm fan NFB9 1600rpm and paired it with the power supply. So far so good. I would suggest making sure you pay attention to the ratings of the fan and the power supply especially those who want to add a few fans, you might overload the power supply and it will fail. I'll update if anything changes but I think it worked for my situation quite well.

Coolerguys Fan Power Supply 100-240v AC to 12v DC 1A Output
Item is as advertised. The power adapter is very compact and small. I believe that this a solid state switching and not a transformer type power supply. I use this to power two 92mm PC case fans for my soldering fume extractor. It powers both of these fans with no issues or heat buildup.

Does the job!
Rigged this PSU to a micro fan in an electric box I installed for my VFD. Works as expected!

Lo compré para un ventilador Noctua externo. Los USB no me daban confianza porque necesitaban más pieza su había gente que mencionaba que se derretía. Este hace lo que debe hacer como un campeón. Directo a la pared y práctico.
