I have three white LL 120 fans in my PC, and they all run fine. Though one of the fans will barely light up and if it does it is the four lights in the center and then one random LED along the edge. The other two fans have the core LEDs working and then half of the fan is lit up on the edge. Sometimes all of the fans' LEDs don't even turn on when I boot up. Is there any way to fix this?
