Hi everybody,

I need your help. I just bought this AKASA Splitter:

http://www.amazon.co.uk/Akasa-AK-CB002-PWM-splitter-sma...

I have 3 Noctua NF-S12A PWM and if I connect them with the splitter, they go in full speed and Fan Xpert+ can't control them. (1200 RPM at any %)

If I connect the fan directly to the same header everything work as expected and Fan Xpert+ can go from 0 to 1200 RPM.

What should I do? I have the ASUS P8Z77-M Pro.
Thank you!

Did you recalibrate fanxpert? click the first tab I think, and click test.

Yes, at every % it says 1200 RPM.

The only thing that I can think about is that I connected the motherboard PIN to a CASE fan header and not to the CPU one.
Is the CPU PWM header signal different from the CASE header one?

I thought that I could use this cable to split CASE fan only, leaving the CPU fan as it is, connected to his header.
