Thick Thermal Pads

Hey, Im looking to replace my thermal pads on the memory blocks ( I think ) on my laptop gpu card. See pictures.

But I have been unable to find anything at all, Been searching on amazon, ebay and gust random google.

The reason for this i cause I have bought a new GPU when the old card died. And so I need new pads ( I think ) or something similiar in function to it. As you can see the pads are stuck to a copper lid and encloses the card inside it with a top lid and bottom lid which is then stuck in place in the laptop.

Thanks^^

Hey man, you can check frozenCPU for pads. The fujipoly 6w/mk are popular.

You can also check ebay...there are tons of pads for sale

EDIT: Tek beat me to it lol

 

Yeah , but I need something like 5 mm thick thermal pads, not 1 or 2,5.

3 might work , but it reall needs to be the thickest i get hold of.
this one is about as thick as i can find on that site
3M™ 8815 Thermally Conductive Adhesive Transfer Tape - 2" x 2" - FrozenCPU.com

It doesnt show so well on the picture ive take but I dont think 1 mm is going to cut it actually. as you can see the dents are really deep from the memory block.

 

Dude, they sell 0.5 mm pads at frozen CPU too...plus EBAY is a huge seller of 0.5mm pads

I'd avoid that 3m cause its tiny...you want to get a larger pad and cut to your specs. its cheaper to do that

 

0.5 mm? according to my math that is half a milimeter which is less than 1 mm and much more less than 3 mm. 0.5 cm = 5 mm
0.5 mm = 0,05 cm.

Or am I missing something ?

 

Oh, sorry...i thought you meant 0.5mm, but you need 5mm.

I don't think they sell 5mm pads...you can however buy some 1.5mm or 2mm and stack them

 

5mm just wouldn't work well at all. Even if it says 6w/mk.

You should get some copper like this:
1/8"/3mm/.125" Copper/Brass Sheet (1 square inch) | eBay
3mm will probably be good enough with thermal paste depending on your use.

I bet he would do custom shapes/sizes seeing as how you probably don't need a whole inch wide.

Also its worth mentioning that thermal pads are only for thermal conductivity and don't add to the thermal capacity of the cooling system significantly, while that much copper I'd expect could seriously lower temps overall compared to an aluminum heatsink designed to fit the way you want it.

 

Hm intresting Niffcreature. So how would I use that coppar ? would I just cut it so it covers the whole thing ( meaning the top part of the sink where all the pads are )
Should I put thermal paste onto each component, add the copper, add a new layer of paste and then put it all togheter? Geez, never want to remove it again if I do it like that lol. Feels like Im baking a cake^^

 

You would have to measure the area and ask him to cut it to size, I think.

I have some heavy duty metal shears AKA aviation snips that could probably cut through 2mm, but I wouldn't want to wreck them with anything thicker. Thats 2mm copper, wouldn't want to try steel either.

Also with metal shears you get these kind of sharp edges.

On second thought if you really need 5mm heres what I recommend: use thermal paste on the heatsink side, the copper pieces will get pretty well stuck there especially with AS5 then buy some quality .5mm or 1mm pads to use on the other side and contact the vRAM (assuming thats what it is).

You're right, paste on both sides is a mess and definitely feels like baking a cake with the cure time of AS5 its how I've done it in the past... Here you have more room to work with, if you're sure about the thicknesses that will give you a really good setup and great temps.
Don't necessarily go by the thicknesses I've said, it seemed like you wanted anywhere from 3-5mm so I guessed. You should try to make sure yourself.

 

Ah the hazzle the hazzle, why do they put stuff on the GPU that you cant even get hold of if you ever wanted to replace it, which it cleary specifies on the label of the GPU card.
Warning: Thermal pads are not reuseable, and needs to be replaced when switching GPU, or something like that is what it says on the little sticker there.

And then there are no vendors that sells the appropriete pads

Ok, I will have to measure the thickness carefully, I guess in this case too little is better than too much. Otherwise it wont fit at all when I seal it.

Do you have a link for a good quality thermal pad of 1-2 mm thick that I use on the vRAM ( yes that is what I meant by memory : )

they even have it on the backside of the card hmm? Everything is diffcult the first time you do it it seems.

thanks for the help Niff^^

PS. what do you mean by AS5? and cure time of AS5?

 

This is what i used for my Clevo:

Hitta Phobya xt på eBays internationella marknad, där det finns fynd att göra i alla dina favoritkategorier. Allting kan levereras till ditt land!

I also had the standard Clevo blue ones from Laird Technologies before...in case it needs more thickness here and there, as according to your pics not all seam to have the same, you may be able to use them double layered...!?!


Edit: My Clevo required 1,5mm and 1mm pads

 

AS5: Arctic silver 5 thermal paste. That particular paste has a cure time before it can achieve it's maximum efficiency.
