4 pin fan header on new motherboards

[hellokeith]

Does anyone have a new motherboard with 4 pin fan headers on it?

What does the 4 pin header do better than a standard 3 pin fan header?

My Intel motherboard gives me temperature and fan RPM, and all 4 of my fans use the 3 pin header to be controlled by the motherboard.



(oh.. and no, I'm not talking about the old 4 pin molex power connector..)

the 4-pin fan connectors are pulse width modulation (PWM) fans

Yeah, it's for fans that have speed control built in. I've got one here that was built for a server. It works fine adapted to a 3-pin header. Just no speed control of course.
