Quiet, but not much air flow when used with specified 5v - probably due to small size. However, 7v+ seems to make a big difference.

It’s a good cooler, I installed a radio in the Android car, when starting up it makes a crazy noise, when you start driving it goes into an almost crazy mode, while I’m thinking about how to connect it with the ability to turn off the functionality of the radio or will I just have to disconnect it from the wiring for the winter!
