Is it okay to plug in a 3-pin case fan plug into a 4-pin socket on my mobo?

If yes, does it matter what side (Left or right) I plug it in? Do I plug it into the socket that says "SYS_FAN"?

Photo of 4-pin socket (Ignore the "CPU_FAN" text in the image): http://www.pcstats.com/articleimages/200801/LGA775install_pwm.jpg

My mobo is Gigabyte GA-78LMT-USB3

    You can plug a 3-pin CPU fan into a 4-pin socket on the motherboard with no danger. The fan will just run at full speed since it is not a PWM fan.
