Looking at the manual for that motherboard, it appears it does not support automatic can speed control from the sys_fan header.
If you're worried about noise, one trick people do, is rewire the fan connector so that when you connect it to the power supply, you ground to the +5V instead of ground, operating your fan at 7V instead of 12V. That, or there are plenty of fan speed controllers you can get, such as a simple inline resistor, all the way to temperature controlled systems.
Thanks! But, do you think that can save a big noise from 3x 140mm fans?
