You didn't say which header. If SYS_FAN2/3 you'll need a PWM fan for speed control. See my post above.

Forgive my ignorance but what does PWM stand for?

Thread Starter 
PWM stands for pulse width modulation. ON a motherboard there are two different things that both deal with that same acronym. PWM is a name of a chip that runs the VRM, it sends out square wave pulses which gives it its name to each phase to designate when and for how long each phase is to stay on.

Then there is a PWM scheme to fan headers, where PWM means 4-pin fan header with the ability for finer control through the same square wave, but in a totally different setting, they are not no way interrelated to the PWM for the VRM.

I stand by what I said. The bios fan control and inteltuner6 is just horrible hardware/software. Honestly if I knew about the fan problems before I considered this motherboard i would have never bought it but while searching people failed to mention the fan problem in reviews.

Well it would seem the problem is more with my case than with the motherboard. The mobo has 4pin connectors, it is my case that has three pin fans, so I'm not going to fault the mobo for that.

I'll get my fan controller soon and it was $6 so I'm not going to worry too much. If it works well I'll order two more for the other fans.

You can stand by it all you want but you are still wrong. The OP had asked if there was a way to control a 3-pin case fan using a motherboard system fan header, and your reply was that it was not possible. You may not like the way it was implemented, but that does not make it non-existent.

It spins to a point but direct control of speed is not possible. I don't understand why you are defending shoddy design.

My last comment on this small argument: you wrote, simply, "There is no way to control the fans." I pointed out you are wrong, especially in the context (as mine) of using 4-pin fans that accept PWM control. Perhaps you meant to say that you don't like the implementation of fan speed control, to which you'll find much agreement here. That's a totally different thing, and your response to barkeater that "it spins to a point" again makes no sense. Probably best to stand down on this one so we can keep the discussion moving along productively here...

yea you have full control over the CPU fan header, and if you have PWM fans then you have control over the rest more or less. If you have 3-pin fans for the other headers then you might have issues with controlling them as well as if you had 4-pin fans.

Hey guys, I'm using the z77x-ud3h with a i5 3570k. Are there any bios settings I should change to get the best performance? I'm currently using windows XP and I'm getting the same frames ingame I was with a e6750 core2duo and a 8800gt. Could it be possible that my OS is holding me back? I'll update to Win7 if that's the case.
