PWM Fan Controller

[Skylark]

Anyone have experience with 4-pin PWM fans (such as AF140s) having variable speed control through a fan controller?

 

I wanted to pick up a NZXT SentryMix2 for my AF140s but I would love to retain the ability to actually change the speed despite these fans being pwm. 

 

Not sure if this fan controller will vary the speed since pwm fans usually need a constant 12V.

 

Thoughts?

If you require to tune your fan rpms to the point where you can't hear them over your speakers booming sound then it'll be worth investing. Most fan inputs are 12v out of the box unless you buy I think Noctua fans which have the nice complimentary 12v to 7v or 5v.

It'll be nice to be able to ramp up and down the fans so sure.

Personally I just change the voltage with a adapter to a speed I like and leave it there

A PWM fan has 4 pins (ground, 12v, rpm sensor, pwm). Using a PWM fan on a 3 or 2 pin connector (as with the NZXT controller) will turn i into an ordinary non-PWM fan which you can adjust the speed via voltage. How low a voltage you can go before it stalls depends on the fan.

Just buy this and set a custom fan curve. http://www.frozencpu.com/products/20988/ele-1196/Swiftech_8-Way_PWM_Cable_Splitter_-_SATA_Power_8W-PWM-SPL-ST.html  Ive got all my radiator fans running off of this and it works great with my AI suite II fan controller

Awesome thats exactly what I was wondering! Thanks!

With AI suite can you control each fan connected to the module individually or are they all synced?

Can't be individually controlled:

 

 

The function of this device is to connect up to 8 PWM devices (fans and/or pumps) to a single PWM fan conector on the motherboard, thus enabling speed-control of all connected PWM devices concurrently.

You control the speed of the the fans as a whole not individually, works great for radiator fans or controlling all your case fans, if you are short on fan headers you can always use Y splitter.
