Hello,
I recently ordered the 4 pack cougar turbine fans, which have 3 pin connectors. This is part of my first time build, and I'm currently thinking of getting this fan splitter:
http://www.newegg.com/Product/Product.aspx?gclid=CjgKEA...

However I don't know if the ASUS M5A97 R2.0 is able to support voltage based fan control, I know that splitter is gonna let the 3 pin fans run at full, and I haven't been able to find a molex adapter that also plugs into the mobo in order to support voltage control for all of them.

Incase anyone was wondering, here's my part list:

Should I stick with the aforementioned link, since apparently hydrobearing fans last a ridiculously long time, or is there a better splitter I wasn't competent enough to find?

More about : good pin fan splitter

Every motherboard I have come across uses 4 pin PWM for the CPU header (and CPU_1) if so equipped

Every motherboard I have come across uses 4 pin opr 3 pin variable voltage for the CHA and OPT headers.

I don't like cable splitters.... too messy.

For 3 pin fans, you have two choices:

-Control them off CPU PWM Header - In this instance your only option is the Phanteks PCB which takes a PWM signal and controls up to 11 3 pin variable voltage fans..... for extra power, you can connect a Molex connector so you don't overwhelm your MoBo header rating (98% of the time will be 1 amp)

-Control them off CHA Header - In this instance you have two options:

a) use the same Phanteks PCB above .... you can not however use the Molex to add more juice as it will over ride the VV signal from the MoBo and the 12v Molex signal will always run fans at full speed.

b) use a ModMyToys PCB

Don't forget a F X F fan cable for MoBo => PCB connection. You'll find that this method is the cleanest way .... doesn't leave a mess aof wires going this way and that.

I am using 3 of the Phanteks PCBs to control 15 fans of CHA_1 (5), CHA_2 (6) and CHA_3 (4) .... Only issue is that the Phanteks PCBs are not actually on sale as yet as separate accessories. Supposed to be released by end of May.

EDIT: Forgot .... this method is great for fan control. The Asus FanXpert2 software (part of AI Suite) does a great job of controlling all the fans and keeping them at same rpm

Where can I find your build and OC information?

The power block method seems most attractive, thanks a bunch mate.
Although could you link the Phantek solution you mentioned? "Phantek PCB" didn't give me much.

How to use the PWN fan hub?
PWM hub will enable PWM function to 3-pin fans. Fan 1 can only be connected to one fan and cannot be split. Fan 2 - Fan 6 can be split to multiple fans. Total of 11 fans can be connected to the PWM hub. All PWM functions will be controlled by fan 1.




The "non Phanteks case owner" version is here in testing phase:
