Can PWM fan use reg system fan header?

[Magnarider]

I have just bought 2 PWM fans but all of my CPU fan headers are full. Can I plug the PWM fans into the regular system fan headers and still have speed control?

Thanks

As long as those headers are 4-pin then yes.

The motherboard is MSI Gaming 7 Z97A http://i393.photobucket.com/albums/pp13/Zane_Magna/FANheader_zpsu4wzeyqy.png thats waht the headers look like

And those are headers are 4-pin - you're good.

you can plug the fan in, and it will spin, but at full speed.
But, if your motherboard has DC fan control, then motherboard can control the speed by adjusting the voltage. If your motherboard don't have that feature, then you need to get yourself some fan speed reducer adapters, which essentially reduced the supplied voltage.
If your motherboard is fairly new, then it should have the feature either via bios or from the motherboard manufacturer website via their software package (usually it's one of the features in a software, you might not see a dedicated software for fan control, so dig around and read its description). My old B85m board had a software called appcentre from Gigabyte that had the smart fan control tool built into the software.

I have the MSI Gaming 7 Z97A MOBO I was hoping to use Command Center to control the fans

Thanks

I think you may have found the solution to your own problem.

Im waiting on the fans i just checked NewEgg and they are on the way. The fans that I wanted were PWM and I wasnt thinking about how they would work on sys fan headers. Gues ill find out

Thanks

i have used 3pin fans on 4pin header, it just spin at full speed. so the 4th pin is for speed control, which you will not be using, therefore your pwm fans will work dont worry.

A PWM fan implies that it has a 4-pin connector... Meaning it'll take full advantage of the 4-pin fan header on the motherboard.
