Just bought Silent Wings 3 PWM. Can I connect it with 3pin header w/o problems?

[VoxPopuli]

So I'm rocking be quiet! Dark Base Pro 900. Neat case.

 

I bought Silent Wings 3 140mm PWMs to use as top exhaust fans. (Not arrived yet)

 

But case's integrated fan controller supports only 4*4pin and 4*3pin. (see below)

 

(Intentionally chose PWM SW3 than 3pin one for probable future case change)

 

Three 4pin headers of case fan controller are already occupied with bundled SW3 as intake.

 

Motherboard's 2 PWM headers also are already occupied with Dark Rock Pro 3 fans and case fan controller PWM signal cable.

 

I heard some PWM fans pose problems when not connected to DC 12V. Such as additional noise.

 

Can I hook up SW3 PWM with 3pin headers of case fan controller without problem?

 

BTW I have a 4-way PWM splitter with molex power cable. Looks like this.

 

If 3pin headers are a bust, then this PWM splitter could work with SW3 PWM and a case fan controller?

Yeah you can connect them without issue, they'll just run at full speed.

Uh... It's quite silent at full speed but I want to lower the RPM when idle for positive pressure. D:

Sadly the thing with PWM fans being noisy in DC mode is true. I've hears everything from weird rotation speeds to something that souds like coil screech in the fan. But there are way too many variables to be able to tell if these fans are noisy in this fan controller using this power supply. I'd suggest you run some tests once you get them. The issues may manifest at specific speed too. Generally speaking I believe it's the very cheap Chinese fans that are most problematic and Silent Wings are pretty high quality.

You can control the speed but it will be done by dc control from the motherboard (if it supports it  )

Seems like 3pin is a bust!

Hmm ok. Wouldn't hurt giving it a try.

That's true. Currently my 3pin fans on controller are working fine so..

Just tested bundled SW3 PWM with 3pin header on case fan controller.

 

Seems working fine with adjusted RPM % range but there's a probablity that bundled SW3 and independently sold SW3 are not the same.

 

Normally they should have same specs but hmm.
