Tutorial: Jimbobjim's GPU Sandwich Method
« Reply #45 on: September 21, 2008, 09:11:00 AM »

I pretty much proposed the exact same thing, but not with X-Clamps. - Six months ago, seemed nobody replied / cared haha (How do you find all threads posted by you?) - It seems turned off on XBOX Scene.

Alright, this was my proposal, with added Wilhelm's improved X-Clamp Fix:

Well, there's a surprise! wink.gif

The MS x-clamp doesn't have the force to bow the motherboard upwards in the first place. The reason it fails is for several reasons. Firstly when MS used the thermal pad they couldn't use bolts to hold the heatsinks down since the thermal pad is of variable thickness so needed a solution that provided constant pressure at variable height. That's why the x-clamps have a certain spring in them. Secondly the thermal pad is a terrible conductor of heat. Thirdly, some genius at MS thought it best to put a tiny GPU heatsink on and cover it with a DVD player and minimal airflow. Genius! And of course, finally, they used a BGA chip cos it was cheaper than pins.

If they'd ponied up the dough and put a decent thermal paste on they could have bolted the heatsinks down but I guess manufacturing costs prohibited that. Bear in mind this is a console that is half the price of a PS3 (yes, I know MS doesn't have Blu-ray but even so!)

The reason this fix kinda works for a while is cos you are putting a little more pressure on the chips by adding the extra washers but it doesn't last cos you still have ye'olde thermal pad and the clamps just don't provide enough... clamp!

What you need jimbobjim, is one of these; X Clamp Fix Kits


Didn't really need the lesson mate rolleyes.gif  I've fixed a good 200 xboxes with regular washers and bolts, and I know exactly why they fail.

Unfortunately, even the good ol' x-clamp kits you linked to on ebay are by no means a permanent fix, and will likely only last a few months.

I assumed you were fairly up on things since you were happy to experiment and all. I was writing for all the newbies who come to the forums to figure out what's what.

Zoneout's method looks excellent tho. Presume you'd have to cut a big ol' hole in the case to accomodate the metal plate and screws tho??? Have you tried it for 6 months Zoneout???

Here's an idea: Zoneout's fix with a hole cut through the metal case and then another one through the plastic. Put a 2" fan there and you'll be pulling all the heat out from the underside of the GPU. Brilliant, huh?

Granted some will but the majority that I fix are working 6 months+ down the line.

Yep. the X-Clamp fixes working 6+ months are the reason why I haven't implemented this method yet.

- Your idea seems alright, provided you can find a fan that can nicely fit.

- Yes you would need to cut a hole in the metal casing to accommodate this method, but not necessary for the outer plastic case anyway.

I honestly believe this method is it. And thanks to jimbob for the idea, and reminding me about this.


- So I would need a kind of a metal with the right thickness and cut a block out of it for the GPU and make the drill holes for mounting.

And in between something that conducts well thermally and is solid enough to put pressure onto the chip.

I did penny fix method and worked for 3 months until yesterday.I got rrod again.Now i want to do xclamp.Is this more stable than Wilhelm's method.Seems like easier.

Actually this method seems to have started with similar ideas to the Hybrid tutorial found in my sig that Wilhelm and I wrote.  Check it out.

has anyone tried the method here http://lee-soft.com/...ne-t1756.0.html ?

It looks like they are just adding more pressure though..
