[c-nsp] Inline Fan Controllers?

[chris]

I had 2 of the same exact fan controllers both do the same thing so I'm
counting out that both are defective but guessing that most likely theres
something they arent doing right. The controllers I have say they control
any 12V fan, and the fan on the 2950g im playing with says its 12V 0.46A so
i think it "should" work. You don't happen to remember a model or part # of
one you used that worked?
