Hi,

I cannot control my fan speeds, have tried with Asrock Extreme Tuner and Speedfan.
Have read threads recommending how to configure-advanced Speedfan, but doesn't work.
I've tinkered with the BIOS settings as well, but can't find a way to completely switch off bios fan control..

Can somebody help me control them please?
I've recently installed additional fans, and it's quite loud now...


I have 3 fan connections on this Motherboard set up like this:
CPU_FAN1 (4pin): Noctua NH-C12P SE14
CPU_FAN1 (4pin): 2x 120mm intake fans - on a Noctua Y splitter
PWR_FAN1 (3pin): 140mm and 230mm exhaust fans - on a Noctua Y splitter

Speeds
CPU_FAN1: 1200rpm permanently
CPU_FAN1: 1247 or 2478 rpm aprox - jumps randomly between the two!?
PWR_FAN1: 724rpm

Should have added that I wasn't able to control the speeds before installing the Y splitters, so that doesn't seem to be it?

Also, my case doesn't have any slots for DVD or fan controllers...

(and I was hoping to solve this without spending more money)
