Hi all,

I'm looking at controlling some PWM case fans with an old Gigabyte Z68 motherboard. Is there a way of 'daisy' chaining off the CPU PWM header? Is this safe? I did see a splitter cable that runs feed from the PSU and the speed control from the PWM header... https://www.moddiy.com/products/PWN-1%2dTo%2d4-Fan-Splitter-Cable-(Sleeved)-.html I can't seem to find this in the UK though?

I'm basically looking to make the system quiet until playing some games or editing rather than having case fans constantly humming away but want them to ramp up to take care of the OC on this older rig. If you have any suggestions then please fire away

Thanks in advance,
Gaz
 
Assuming all your fans are PWM the PWM splitter you listed will work fine. There are many PSU powered PWM fan hubs and spliters out there made, but for some reason seem to be in short supply here right now. Just make sure whatever you get uses PWM Sata or Molex PSU to power fans with motherboard PWM signal to control their speed.

Phobya 4Pin PWM to 8x 4Pin Fan Splitter PCB are avaliable here in UK, but OcUK does not allow us to post links to competitor sites.
If you Google "PSU powered PWM splitter hub" you should find some. If that doesn't work drop me a trust message.
