Yes ,"Cool â€˜nâ€™ Quiet" is enabled. Interesting that on mobo there is only 3-pin cpu fan socket. Cpu fan has tree wires (black - ground, red - positive, yellow - rpm reading). There is no pwm-control wire, so it looks like it's impossible to control fan rpms.
Anyway, i shall limit it manually, by putting a resistor (or better thermistor) into fan circuit. But I'm still curious whether controlling of fan rpms using 3-wire is possible or not?
