now easily be connected to the
contact pins on the circuit board.
Pay attention to the correct polarity

("Red wire to the left " also
applies if you did not have to
remove the white plastic jack
from the circuit-board!)
The color-sequence of the
cables of the replacement-fan
does not necessarily have to
coincide with the color-
sequence of the cables of the
defective original fan!

power and switch it on, to check

CPU Fan is Locked' should be gone
now.
If necessary, check the plug's snug
fit.
12. Re-attach the side-panels according to
steps 5, 4, 3 and 2.
