Question about the fan controller on the Xaser II case...

[batmanuel]

Just helped a friend put a new rig together last night and it all went pretty well, with one exception. His case is a Xaser II 5000A, and we connected the fan speed controller to the CPU fan (Volcano 7+), which was pretty straightforward (connect molex on one end, CPU fan connect on the other end). The only problem is that when we flicked the power on, the red and black wires that went to the CPU fan connector got really hot and melted through the insulation. Thw wires were glowing hot. Luckily I turned it off before it shorted out the power supply and damaged any other components. It scared the crap out of me, though, the first time I've ever caught a computer on fire.

My question is what the heck went wrong. There really isn't a way to screw up the installation since the molex and fan connector can only be plugged in one way. I am at a loss to figure out what went wrong. Any one else run into this? I want to try to figure out what went wrong before we replace the switch with the one that came with the fan (which AFAIK is the same one that is installed in the case) so we can run the fan straight off of the power supply rather than the motherboard header (which isn't recommended, but should be okay since it is a MSI Nforce2 IGP with the extra ATX 12V plug to give the board a bit more juice for running fans).

I have contacted TT, but I was wondering if anyone here has anything they can say.

The power supply, BTW was a Antec True 480W w/ blue light.

So was the cpu fan powered by the mobo connector or the fan bus? Or maybe there is a seperate rpm connector on the fan bus which is connected to the mobo?
