Hi I bought this http://www.overclockers.co.uk/showproduct.php?prodid=CB...

Wherever I connect Akasa Splitter the fans are rotating at full speed still. I tried case fan connector, which I found later that I should use CPU fan. Tried CPU fan, fans still all 100%. Can somoene give me an advice where to connect it? Which connector is PWM on VI Hero then?

your fans are 3-pin or 4-pin fans?

3-pin fans are not PWM fans

Go into your BIOS/UEFI and select Advanced mode for the Q-Fan (CPU Fan). That will tell the motherboard that the fans connected are voltage controlled and not PWM. Right now, your mobo is sending PWM control signals that can't be received by your non-PWM fans, so they're running full-time at 12V.

Actually, now that I think about it, that won't work either - that splitter (I have the 3 fan version) draws it's power direct from the PSU. The only connections to the mobo are the RPM report wire and the PWM signal wire. All hooking up all those fans to the mobo will get you is an RPM report for a single fan. All of them are still going to run at max.

You'll need to either switch to PWM fans (4-pin), or connect the fans to the mobo fan headers without the Akasa (or use a fan controller). Sorry.
