I have an asrock extreme4 p67, I'm not sure if it works the same way on other p67 boards or not.
I have 2 values for CPU fan speed control:
Fan Target Speed (1-10)
Target Temperature (45c-65c)
I figured maybe it meant the fan will attempt to be at (target fan speed as percentage, 6 = 60%, etc) at the target temperature, and scale up/down from there, but that doesn't seem to be the case.
But that's not what it is - for instance fan speed 7 is definitely not 70%, because even at idle it spins my 2100 rpm fan up past 2000. So basically 7 and above are 100% fan all the time. Level 1 keeps the fan spinning at 1500 rpm even at idle temps.
The target temps also don't seem to affect how much the fans spin at low loads. The fan spins at the same RPM whether I set the target temp to 45c or 65c.
And under load, even with fan target speed 1 it still spins up to 2100 rpm.
What exactly is the logic behind how it handles those 2 numbers? My fan gets noticibly louder after 1800 rpm without that much extra cooling, so I'd like to cap the speed around there, but even the most lenient settings (fan target speed 1, target temperature 65c) end up running the fan at 100% 2100 rpm.
