Hi,

I have 4x Noctua Industrial Fans connected to a PWM fan splitter cable (sata powered) connected direct to my motherboard and controlled by the fan control settings in the BIOS.

Is there a way of setting each fan speed rather than all the same speed using the pwm spliiter cable?

thanks.
 
They will need each receive a different voltage or PWM signal. Either plug them into different fan headers (3 or 4 pin shouldn't matter) or get a standalone fan controller like a grid+ v2.
 
You want the PWM signal from the fan header on the motherboard to be different for each fan, the only way you'll do that is to fit inline resisters to the fans that you want to spin slower than the others but I don't think the Noctua ones work with the industrial fans.
 
cheers guys, hows the CAM software for the grid+ v2? ... I had the grid+ v1 and found the software buggy and was always crashing plus could only control the fans down to about 1200rpm.

Think i have a spare sata powered fan splitter cable somewhere, will give this a try.
 
Cam software has improved a lot recently, just wish it would control my H100i and then I'd ditch corsairs software completely.
 
The reason I bought, use and strongly recommend the grid+ v2 is the easy independent fan control of 6 channels. Don't know what issue P4Clock has but mine just works.
