I bought an FD that has a Billion Fan Controller installed. The stock temp gauge is inoperable, so the previous owner installed this. I don't know much about them, does anyone else? It seems to work fine, kicks the fans on high when it reads 100c, but I am not sure if it is really accurate or not. I'd like to know where it is getting it's temp reading from as well.

Also, if any of you have the directions to one of these units.

Thanks!
