Power small fans with USB
Posted on 2012-03-21
I wanted to check with the hardware gurus here if it would be possible to power old, small CPU cooling fans using the power from a USB 2.0 port.
I have a AIO system that I would like to throw some more air in thru the bottom. I have several small old CPU fans ((80286, 80386, etc.) that I could mount to bottom of the system, but would prefer not to have to open the system to get power to them.
Therefore, I was wondering if I could wire the fans to a USB connection & plug it into one of its ports. I have more than enough USB ports.
