I've always felt the RGB led is a bit underused by the fan being either at 100% or off, so I altered the relevant bit of temperatureprobes.h to:

  // 0=auto (by sensor), 1=manual
  if ( dewconfig.fanmanualcontrol == 0)             // check if fan control is under fan temp sensor
  {
    if ( boardtemp >= dewconfig.fantempon + 10 )         // if board/case temp too high
    {
      fanspeed = POWER_100;
      updatefanmotor();
    }
    else if ( boardtemp >= dewconfig.fantempon + 5 )
    {
      fanspeed = POWER_75;
      updatefanmotor();
    }
    else if ( boardtemp >= dewconfig.fantempon )
    {
      fanspeed = POWER_50;
      updatefanmotor();
    }
    else if ( boardtemp < dewconfig.fantempoff )    // if pcb temp < dewconfig.fantempoff then turn fan off
    {
      fanspeed = POWER_0;
      updatefanmotor();
    }
  }
  else
  {
    // manual control of fan by motor speed setting
    updatefanmotor();
  }
