Review: Nice Fan power adapter versatile in how you could use and great for pretesting fans before install. - Perfect, I have had a few noisy 120mm PC fans recently, this adapter is nice as I can pre-test fans before spending the time to bolt them into my PC with 4 screws. You could also use to power an entertainment cabinet fan to keep PC or electronics cool, I did something like that for a PC with good GPU that was house in cabinet so that air flows from large 300mm fan in front and then out back of case and out entertainment cabinet. Keeps temps nice! Provides the power needed to one fan well, I test with RGB dan and it ran quiet had no problems powering both the fan and the LED's.
Review: 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.
