This is not to be plugged into a PC USB port but into a USB wall plug that you get with mobile phones.
I've got 3 5v fans but they are so loud and when the 12v is running on 5v USB it generates enough airflow at the slower speed and is super quiet, perfect for my needs. The only question is.... is there likely to be any type of safety hazed?
