I'm not sure if the LED is dead but if it is, then it's more than enough for me to get the unit replaced. Unless, you are ok using the cooler with out the LED.
Now that grinding noise coming from the rad, is not really the rad, it's more like coming from the fan. Try connecting the fan directly to the MB fan header and see if the noise follows.
There is no way to tell if the fan controller works because the fans that you are using are non Corsair. Only way to find out is to use the stock fans.
