Shim for Matrix HD7970 Platinum die?

cubusmedusa · Aug 25, 2014

Hi,

unfortunately I was not able to find a photo showing whether or not the die height is lower or equal to the frame around it thus making a shim necessary for installation of a water block.
Is anybody out there knowing an answer?

If I look at pictures of the cooler I could get the impression that a shim will be necessary to avoid contact of the copper with the aluminum frame around the die. But I am not sure.

Frozen cpu sold them at least at one point

Looking at the card a few months back, I believe they brought the die up on the Matrix.

However simply check it with a credit card to be sure as I do know the Lightning and all reference models needed the shim. Seems odd the Matrix would not need it, but it did come to the party late and possibly was addressed by the ROG engineers.

Of course, checking by myself would answer it. But I am in the situation now, considering the mod. Not having decided yet. (having some other problems to solve with my HAF XB as well) And as long as I am not sure I do not want to take it appart. Thats why I am asking.

Only a few screws. not a bad idea to replace the factory goo anyway even if you don't move forward with the block

or just grab a shim so either way it will work as they are only a few bucks

Hmmm, I have bequiet DC-1 and Coolab Liquid Ultra at hand...
dunno...
there was this huge test of TIMs where the liquid metal pad showed surprising results

never used liquid metal ?

I typically use Gelid Extreme or TX 2

cubusmedusa · Aug 25, 2014

Yea, I saw that a lot of people are using the Gelid Extreme and/or TX-2/TX-4. The reviews more or less confirm this. But I was quite surprised about the GPU/TIM results which led me to think about the pads...

You have a great opportunity to do some testing for yourself.

Taking a GPU apart is really no big deal. Just watch the stickers as some will void your warranty if removed or altered. you know there pricks when they put the stick on over a screw :rofl:
