My dad just went to a car show and swap-meet recently and picked up an interesting piece of computer equipment for me.
He bought a massive fan assembly that has nine 120mm fans on it. They were mounted to this assembly in three rows of three fans. All the fans are plugged into a Silicon Graphics Computer Systems circuit board which seems to have been made for this application. The SG board also has a serial cable attached to it that runs to a male end serial port on the end of the framework that the fans are attached to. The fans all have a white, brown, black, and red wire running out of them. The SG board also has a socket that looks like the female end of a printer cable, but much smaller. I'm guessing that this was some sort of power socket, as the fans are not otherwise getting any power from the DC adapter at the end of this huge assembly.
There is a number of the SGCS board that reads "Assy NO 030-0941-005" I have looked all over Google for this number along with Silicon Graphics, but I am unable to determine what this piece of equipment once belonged to. The fans are marked "NMB Model: 0475KL-04W-B46" They are 12 Volt and 0.90 Amps.
If you know if/how I could wire these fans to work in a new system, or how I could get them to work with the fancy Silicon Graphics control board that they came with, please shed some light on this situation.
