Where the heck is the system Fan 1 header on my motherboard?easy question i know but its driving me nuts! I found power fan, cpufan, systemfan2, but no systemfan 1.

I have a dual fan cpu cooler and wanted to use my motherboard to measure there rpms but there three pin fans and my motherboard has 3 pin fans for systemfan 1 and 2 only and i cant find 1!!!! lol its killing me,

heres my board.

GA -990fxa-ud3 am3+

Natrually i threw out my manual with all this mapped and listed out. I cant find the digital manual on the companys website either. Im sure im just wound up and frustrated but here it is.
