Fan Replacement -- Alternate Power Source For Fan - Microsoft Xbox Repair Manual

Fan Replacement -- Alternate Power Source for Fan

If your Xbox starts to flash yellow after playing for several minutes just fine, you may be seeing
some heat issues.
This can be caused by many situations, pile of dirty clothes not allowing enough air circulation,
running it anywhere it is destined to get too hot. Also they do get clogged with dust from time to
time as well. Another frequent problem is failure of the case fan; occasionally the power header
on the board fails.
Replace Fan:
Use something to pry out the two tabs on either side of the fan that hold it in place. I use the T10.
The fan is removed by sliding it up about a quarter inch and then will freely move forward. Start
by releasing one side enough so that you can pull up on the fan and the clip does not fall back in
place. Then proceed to the other side and you should be able to move the fan up and out.
Alternate Power Source for Fan
Go to your local computer store and find one of these. If you have a box of adapters that came
with assorted PC case fans and may have one lying around.
Insert it inline to the cord going to the hard drive and your all set! Whenever the Xbox is on so is
the fan just as it is with the motherboard power header. This is also known as the 12V fan mod.
By going straight to the power supply 12V is provided to the fan rather than the 8 or so the
motherboard provides, faster fan, more cooling.
