Im about to try to hook 2 AF140's on a 4 Pin y Splitter i know it wont be able to control RPM because its a 3pin header fan, my question is if i connect the 4 pin header to my motherboard would i be able to control the 2 AF140's? thru software like SIV on gigabyte? or Asus fan expert? need some expert advice. THANKS!
