I've just bought a P8Z68-V GEN3 mobo (+2500k, 8 gb Corsair Vengeance LP White -1.35V), I'm using my "old" Noctua NH-D14, with the 3 pin Noctua fans.
I tried controlling the fans in bios/windows utility, but it won't do anything, they are spinning at their max RPM, and it is a little loud.
What is the problem, how can I control them?
(on my old Gigabyte P35 the auto fan control worked fine...)
Under cpu temp/mb temp
CPU Q fan [enabled]
CPU fan spd low limit [600rpm]
CPU fan profile [manual]
CPU fan maximum duty cycle [100%]
CPU fan minimum duty cycle[20%]
mine rams up and down with load this way hyper 212+ on pwm fans though, i don't use any software just cmos bios.
