gluing shim to CPU

[ve6jhc]

Anyone try gluing a copper shim onto the top of a Tbird? This would stop the worry about the shim moving and shorting out the bridges?

[lennytiger]

If you want to do this do not use a glue with any abrasives.

You should use something that will stick it down just so it doesn't slide around. A tube of Loctite all purpose adhesive will work fine while I haven't tried it I see no reason why not to. Just be sure to put very little glue on you don't want to find that the glue has got all over the mobo!!!

Just a tiny drop of clue and then push litely make sure none of the glue touches the mobo..


Other than this advice I would say your on your own!!

[Phil]

I wouldn't unless you were then going to lap the shim as the layer of glue would raise the shim slightly lifting the heatsink off the core, if you are worried about shorting something then use a none conductive shim

[ve6jhc]

I was thinking of a very thin super glue...just a dot in each corner. I think that the glue will spread out into a very thin film that will not raise the shim.

[lennytiger]

just make sure it isn't an abrasive super glue and your all set

It only has to raise it a few thousandths of a milimetre for it to hamper cooling, especially with an un-even heatsink if you haven't lapped that. If you do do it which I don't recomend then put a thin layer of heat transfer compound on the core and then place the heatsink on and then remove it to see if it fully contacted the core, if it didn't then you would need to lap the shim down a bit.
Honestly though I recomend just using a none conductive shim.

i really dont see the reason for gluing a shim to a cpu

why don't u just glue the shim to the heatsink instead?

i have seen this done with thermal tape and regular sctoch tape before

that would have the same problem as gluing it to the chip in that it would raise the heatsink too much, execpt that way you wouldn't be able to lap it exactly

[killem1x1]

I used a dot of superglue on my shim, but I glued it to the coldplate, on my waterblock/pelt setup. I think it would work out fine if you glued it to your hsf...

[lennytiger]

for safety you guys maybe right, but with all our contributions and ideas he's still on his own.....

[Random Nonsense]

how about this: lap the heatsink. then glue shim onto it, then lap that to negate the effect of a layer of glue?

Thats what I suggested to do, but really you would just be better using a none conductive shim.
Another way you could do it is not to actually glue between the surfaces but around the out side

Phil how many times have you said to buy a nonconductive shim?

Anyway that last idea is probably the best but why not use a few dabs of AS2 to hold shim to the HS? If you use regular AS2 it sould hold the shim in place while pushing excess grease out(you shouldnt use much anyway) so you can have little if any expansion of the media used to hold the shim in place.

Now I must say this cause it is the most practical solution: Buy a non-conductive shim! If you are afraid to install the HS without a shim and are also afraid of shorting the CPU then make the investment and purchase a non-conductive shim! Its a very simple solution to this problem.

[lennytiger]

why bother with the shim I don't use one, why should you??? they increase your temps anyway and if you mess the glue or something then you may as well kiss the chip goodbye!!

I agree and dont use a shim either but somepeople are heavy handed when they instal the HS and dont want to chip their chip.

Who counting :) any way no one seemed to respond to my suggestion

As for not using a shim, well there are some heatsinks I wouldn't use one with, the glaciator for example has such a gentle clip that you would have to be trying to break the core. But if I were using a Global Win I would definately use one. It may increase your temps slightly, which may in turn mean say a 50mhz less overclock, but I would sooner settle for a 2-3% speed drop than a dead chip

[CrystalMethod]

Incase no one has suggested it before, I'd suggest in investing in a non-conductive shim. :D
Seriously though, the non-conductive shim is the way to go (like Phil stated) without having to worry about anything else, and go through the trouble of guling anything, making sure it's on "just right", etc...

[ReTiCuLeX]

I suggest not using a shim I have burn't a 1.2Ghz AXIA - Y athlon using an non conductive blue anadoized shim on my epox 8k7a mobo. The shim didn't allow proper heatsink contact to the cpu which caused my cpu to fry, btw the shim was really flat too.

[Wahoogie]

Dun use a shim.... if you're careful putting on the HSF there is no need for one...just dont put the HS on at an angle and you will be fine, rather then risking a slip of the shim and shorting your chip.

I am now using a copper shim on my 1.2birdy
but it is just rubbish well i keep it on cause it looks better
i wouldn't glue it on, what's the point??

you can see the shim when u have the heatsink on the chip?
wow

my opinion is that shims are just plain garbage......all it did was raise 8C temp and make me lose 50mhz overclock

but i would suggest it if u are using a cak38........the clip is so stiff...i chipped one t-bird already because of the dam* clip
but i learned my lesson so i replace that clip with a FOP32 clip and it's all fine now

[Mr.Lansing]

Well i agree that the copper shim is useless
but i dun't think that it will raise your temp by 8 degrees
well did it really raise your temp by 8 C
that's a lota difference man!

[!-=sky=-!]

it did........
even after i lapped the shim it's still the same..........
i dun even know where that thing is now

This is a thread reply from Silversinksam in cooling

First I'm a retired engineer with a pretty good understanding of cyanoacrylate properties

Cyanoacrylat e(superGlue) has a flash point of Flash Point 83° deg C and has an even lower boiling point of Boiling Point 62 deg° C may become unstable at high temperatures. Under certain conditions, slow depolymerization of the polymerized cyanoacrylate has been shown. Now is this the sort of product you want affixing your expensive video card's HSF. Not to mention if your not using Superglue Gel the migration of the viscous liquid could cause you undo propblems.

Wht dont you spend a few minutes and read the MSDS white papers on Superglue, you will see why its not such a great product to use in a high heat envirment.

PS they make high tempature Cyanoacrylate adhesives but its probably not the garden variety stuff available in most stores.

i Agree with ReTiCuLeX about not using a shim, the same thing happened to me when i misaligned the non conductive blue anadoized shim like the one ReTiCuLeX described. I was using a 1.2Ghz AXIA - Y (wk21) factory unlock, it ended up cracking my CPU and the worst thing is that i only had my cpu for 2hrs.

well do anyone know how I can make it in to a key chain? I just recive my cpu, its a 1.4 AYHJA – F factory unlock, also does anyone knows the potentials of a ayhja – f stepping?

[Hugo 59]

I don't use shims, but if I was going to I would probably get a non conductive one.:D

well then i guess u musta installed the copper shim wrong or maybe the contact between ur HSF and cpu core is not that good after putting the copper shim on.
well just leave it off!

[!-=sky=-!]

ummm..........i m sure i installed it the right way.....anyways............i lapped the damn thing.,...it's still bad.....i got myself another keychain
haha

and i never did or will waste my money on these garbage

it came with my 8kha
