2010-01-30 18:13:46rev. 2ERROR FIXEDDoubt if the connector is IDC. It is 3 pin male 2/54 pitch. But not IDC.APPROVED
2010-09-11 16:36:55rev. 4CORRECTThis is mostly accurate, except for the sense wire: when the fan is running, the sense wire has 1.5v, but if the fan is not running then the sense wire is 0v. APPROVED

2018-04-22 20:36:50rev. 11ERROR FIXEDThe pinouts are correct, but I believe the the descriptions for the pictures are swapped. '3 pin IDC Male connector at the cable' should be on the right, and '3 pin motherboard fan connector' should be on the left. APPROVED
