3.X-Clamp Fix
For most consoles, only the GPU x-clamp needs to be replaced, but some also require the CPU clamp
I
a)Remove the DVD drive by loosening the tape in the front of the console, lift the DVD drive and detach the two cables from the motherboard at the rear.CLICK ON ANY PICTURE TO ENLARGE. | |
b)Remove the fan shroud using a small slotted screw driver to push the tab holding it in place and lift up and out. | |
c)Next, unplug the fan. Then lift up on the steel flap holding the fan in place while pulling it toward you. | |
d)Remove the power button/wireless controller board using your T8 Torx driver. There are three screws; one is behind the plastic LED lens cover. | |
e)Remove all 8 heat sink screws (T8) holding the processors to the chassis. | |
f)Remove the remaining motherboard screws using your T10 Torx driver. | |
g)At this point the motherboard will lift out. Use GPU heat sink to lift the board up and out. | |
h)With the motherboard removed, the X-Clamp is accessible.This is the most difficult part and should be done delicately or you may end up damaging the board. Begin by wedging a small flathead screwdriver between the clamp and the stud. Then gently rock the screw driver back and forth and the clamp will eventually work its way up and off of the stud. The third will become very easy to remove and then it will just pop right off. | |
i)With the clamp(s) removed the heat sinks just lift off.FOR VIDEO OF STEPS 3a THRU 3i CLICK HERE. | |
j)Once the heat sinks are removed, use your wrench or pliers to remove the studs. | |
k)Now you will need to clean and prepare the processors themselves. Start by removing as much of the old thermal paste as you can with a tooth pick. Then, use alcohol and a Q-tip.This may take a little effort.In extreme cases, you can use Goo-gone.If you use Goo-gone, make sure to clean as much off as possible. The processor dies should be clean and shiny.Clean the paste residue off of the heat-sinks also.FOR VIDEO OF STEPS 3j THRU 3k CLICK HERE. | |
l)Take 4 screws and 4 washers and place them through the board from the bottom with the washer between the board and the screw head.I suggest doing one heat-sink at a time.You can use scotch tape to keep them in place as you turn the board over.Place a washer over each screw to act as a spacer between the board and the heat-sink. | |
m)Apply a thin coat of thermal compound to the die. Refer to the photo for the amount of paste to use. All you need is a skim coat similar to the thickness of plastic wrap. | |
n)Place your heat-sinks onto the screws and hold it in place with one hand while carefully putting a couple of turns on each screw to keep the washers from falling off. I place the unit on the edge of a table and from below poke my screwdriver through the tape and turn the screw in a few threads. Do not tighten any of them completely yet. | |
o)Once all the screws are attached, peel the tape off of the screws and prepare to tighten them down. Turn each screw gently until you feel a little resistance. Do this to every screw before actually tightening them down. Now similar to the technique used in mounting your wheels on your car or bolting down a head on your motor; begin to tighten each screw slowly in a kitty corner fashion making sure to evenly distribute the pressure across the processors die. Tightening down one side and then the other can result in a cracked processor die. With your large screwdriver put the final turns on each screw. You really can’t make them too tight unless you actually strip out the heat-sink.FOR VIDEO OF STEPS 3l THRU 3o CLICK HERE | |
p)Place the board back in the chassis.Reconnect your power button assembly/wireless board. Plug your fan in but do not reinstall it. Connect your DVD drive so you will not get banned from Live for powering up your box without the drive connected. Now with your Xbox basically re-assembled except for the fan shroud, plug your power and video cords in and proceed. | |
q)Now for the most important part and most likely the point where the majority of people who were unsuccessful completing this fix failed.This step requires you to overheat your GPU. Many tutorials tell you to unplug your fan and turn it on until it overheats. There is one major flaw with this approach. The thermostat for the overheating protection of the 360 is contained within the CPU. The problem is that the CPU overheats without any airflow before the GPU is able to get sufficiently hot. | |
r)In order to cool the CPU but not the GPU it is again important to have your fan shroud removed. Now take your fan and lay it on top of your DVD drive with one of the fans over the top of the CPU. This will keep the CPU cool to prevent it from overheating while the GPU will get extremely hot.Don’t burn your fingers. | |
u)If it did not work for you, try tightening the screws even more and reheating. | |
