2 cables on this cpu fan.. do i use both or pick one?

[ShadyBob]

hey i just got all the crap for my cpu in today and i got it all assembled right (i hope so anyway), theres a 3 pin connecter and a 4 pin connector for the 2 fan calbes... do i use both or pick whichever is most convenient?

Use both... the 3 pin is for monitoring and the 4 pin is for power.
