4 pin fan into 3 pin mobo? Tags: Homebuilt Connection Fan Cases Motherboards Systems Last response: July 3, 2010 1:51 PM in Systems Share Majornoob July 3, 2010 12:55:35 PM Hey guys, Basically I'm wanting to connect a 4pin case fan to a motherboard that has a 3pin system fan slot, (mobo is a gigabyte MA-770T-ES3). How could I do this? Would I need an adapter? Furthermore is it important to connect the case fans to the motherboard at all or could I just connect straight to the power supply?

Majornoob July 3, 2010 1:35:12 PM Thanks for the reply. Given a choice I assume it's better to connect the fan directly to the psu? Can't find your answer ? Ask !

Then again it is all depending on the location of the fans, there is no better or worse in this case more about convenience. Can't find your answer ? Ask !
