These fans are not commonly used. They are:
- 120mm X 38mm
- 12V
- PMW(I don't even know what that means)
- 4 pin connector
But it's a different kind of 4 pin connector. I tried one of my 120mm PC case fans and the 4 pin connector didn't fit. The little pieces of plastic on top of my PC fan connector are aligned with pin 1 and 3. On the Antminer fan the little pieces of plastic are aligned with pin 1 and 4
It's the third connector in that picture, the one labeled "4 Pin with PMW signal Molex small"
http://media.bestofmicro.com/0/H/312353/original/molex-en.pngI have yet to find those types of fans anywhere. I googled a bunch. Looked on Ebay and Amazon but they always have the wrong connectors. Are those fans even sold anywhere?
