Copper Shims. Need Advice! pics might be big

So I have been looking at copper shims to help cool the gpu on my laptop. Well actually its for a friend who just started having heating problems on it. He has an MSI 1651 9600mgt, Since me and him have identical laptops except Im getting a P9500 and he has a T9400 and of course my res is better. I told him I would test all this off in my laptop first, and if this works id help him with his. I need help on where to install it and where to put the thermal paste on it. I use arctic cooling mx2.

Now still a noob at forums so ATM not sure how to reduce the size of the pics, so i am sorry and a description of what i think i should do? or at least have to?



For the squishy things on top of the heatsink b and c should i replace those and add copper shims on it? and how would i put it on? Should i add copper shim on the fan for A? And I think imo D isnt really a necessary but was wondering if it would help to put it there too? http://i905.photobucket.com/albums/ac259/espada09/IMG_0468.jpg



and of course the gpu. I know i will add the shim on the gpu itself (A) but should i also add shims on B-E? i saw on another thread that he put copper on the memory chips but was wondering if he put on top of the heatsink or he put smalls shims on the chips itself and also above it? just a few questions

Any input would help and is it wise also to add on the cpu for my friends laptop? any help of some sort will help me out. Also by any chance if anyone has already done this what is the size of the shims you used or I should get?
and is thermal tape bothsided best for putting copper on top of the heatsink and/or memory on the gpu. Thanks alot! any advice I will post temperatures of before and after once i get enough posts. And also once i get my new cpu and ram (back from ocz had to rma).

 

heating problems?
look at my specs in signature.
I undervolted my 9600m GT to 0.89V and overclocked it by just over 20%
My temps under heavy load don't go over 61 deg C (although granted, I also undervolted my CPU).

Before you go off making copper mods, ask your friend when was the last time he cleaned out his air vents.
If it has been a while, then I recommend he opens up the laptop, remove the cpu cooler and clean away.

Also, undervolting that gpu to 0.89V by bios flashing the card is what I'd sooner recommend.
CPU undervolt as well.
If I was able to get my temps to such low levels with a 20% OC (625/1550/900) on the gpu (through Nvidia control panel) and brought it to 9700m GT level, then so can he.
That's the bare maximum increase in clock speeds that the gpu can function on under 0.89V.

Clean out the air vents first, undervolt both the gpu and cpu, and you really won't have to worry about copper mods (unless you want to do it for the sake of it).
I might give a copper mod a try for the fun of it and testing purposes.

As for where the shins are supposed to go ... well, since I haven't really did anything of the sort yet, I won't be commenting on that.

 

Yea i told him to do that. Of course thought about undervolting it but, I also wanna give this a try to see how much it improves or if it does. Just wondering also like taking things apart and making it better so this would be good practice and if this works o man ima be one happy person, overclocking both the cpu and gpu and never have the worry of omg its super hot its like a sauna LOL jk. But i just wanna try it for sng.

 

The "squishy things" (A, B and C from your first photo), for lack of a better term, have nothing to do with heat transfer; they're just there to fill the gap between the heatsink and whatever lies above it, maybe the keyboard or something, depending on your model. They just help to decrease flex in the chassis, like shock absorbers. You should leave them where they are.

D (in the first photo) is your chipset northbridge. It's not necessary to put a shim there, as those usually don't get too hot. It's entirely up to you though. As for the GPU memory modules, I have no answer for that; I've never had an MXM graphics card. I leave that to the pros.

 

Lol thanks for the response yea i know squishy things is the best word for them. You think i should put a shim on the cpu? or just say nah just because its a P series?

 

It's always better than the thermal crap that most laptops come with. Just make sure you put some good thermal compound on both sides of the shim.

 

Alright this includes the northbridge I am guessing. I use mx2 arctic cooling.

 

and you should read 'shim' in terms of copper foil. Not too thick or you'll be introducing stress that could easily crack something in two.

 

yea that i can find on ebay at least the shims people sell are either .75mm or 1mm or .8mm not sure which to choose prob gonna go with the .75mm.

 

Pic size is fine.

As said first photo A+B+C are just support pads. Leave the D pad for the northbridge

Second photo, your supposed to copper mod A (GPU core), B+C+D+E are GPU memory. While it isnt necessary to copper mod these, it is possible. The clearances might or might not be different to the A, so you might need a different size shim. If they are the same then you can use a 2x long rectangular pieces to cover all 4.

hmm alright well looks like i dont need to do anything about the northbridge. you think if i use 1mm for the gpu itself and two long rectangular a bit smaller it would work. What about the cpu it should be fine IMO, or should i put it on anyways. I still think i might put it on northbridge.

 

I definitely recommend putting it on your CPU.

 

usually the heatsink surface that in touch with the processor die is copper.
if it is, there's no need to coppermod the cpu.

 

okay what about the northbridge?

 

if you have extra copper, I'd say why not?
good to replace all of that thermal pads, copper would be whole lot better

 

okay now for what dimensions to put 1mm thick or .7 or .8?

 

it should be depending on the thickness of the pushed area of the current thermal pads (means you have to open them up first) for better selection.

 

well found out that my cpu does have copper die on the heatsink for it. Just gonna do on gpu and also northbridge and prob getting the T9600 again and undervolting it this time! im so excited cant wait till i get the money next week to order it!

 

great! I bet it'll be a great machine after the T9600 and coppermod

 

of course T9600 + overclocked gpu to match 9700mGT its gonna be a beast machine plus prob gonna try to get an SSD!
