i've just purchased this case from newegg,
looks pretty impressive so far with 7 built in fans...

I managed to fix almost everything in order,
but I was left with one 3-pin cable that comes along with it. Don't really know the use of it.
the manual does not really explain the use of the cable.

it has 3 labels - PCB connector
MB connector
and CPU Fan,

my model is the V2000A

can anyone who has the same case or similiar thermaltake cases give me tips about this?
