Can someone help with changing out fan?

The fan is moving slowly and i think is dying. I bought another fan. Do I just need to sodder the red with red and black with black?  If I add a heat shrink, it won't melt it later because the extruder heats up?

Also, later if I want to print with PLA i'll need another fan, where do I make the connection?

Yeah, solder it in line red to red black to black.  My fan died like that too, slowing down and getting sticky.

For the second fan, there is a header on the board somewhere for a g-code controlled fan.  There are also threads that give a complete tutorial on how to do that, I believe.

Should I go ahead and cut the yellow taping?  To get more room for the wires, or just zip tie the excess wires?
