Gigabyte z77 ud3h sys fan

[hedgehogpie]

Hi,


I got a mobo gigabyte z77 ud3h, I connnected a 3 pin fan to a 4 pin in my mobo in sys_fan1, my questions is that how can I change my 3 pin fan speed which is connected to my mobo's 4 pin?

4 pin fans are controlled by PWM, and 3 pin fans are controlled by voltage.
1)you can go to BIOS to set the fan fan control method.
2) or try use the Speedfan software.

so it's really ok to connect 3 pin fans to 4 pin in mobo (sys_fan1) right? Speedfan software like this one? http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html
