thinkpad thinkpad yoga s1 - 6 wires,? help

[E.wadsager]

Hey 

im about to order a new fan for my thinkpad yoga s1, since the old on is starting to get noisy. 

Why does the fan have 1 extra wire that seem to be soldered to the heat sink. 

Will this be a problem.?

I think i might cut the old wire and solder the new to it, since it seems easier then solder the new wire to the heat sink.
