Copper shim for 7870?

post #1 of 4
Thread Starter 
Does anyone know if a 7870 tahiti copper shim exists? I just removed my heatsink but the gpu die is about 1mm taller than the surrounding metal heatsink around the gpu die for some reason...I made a picture here to explain what I mean.



Anyone know whats up with this?

That is what you want.

A shim is to fill the gap when the die is below the metal border of the GPU - if it is above it, then you're fine smile.gif.

There is always a small risk of cracking a die, but adding a shim to a protruding GPU won't help lower that risk at all.

If you have a caliper, you can measure high high the die sticks out and run a thin piece of rubber or vinyl or something that thickness surrounding the core to spread the load out. Direct contact of the die is a good thing for temps, if I could get away with not having to use a shim without filing down metal around the GPU or heating it with a torch to remove it I would smile.gif.
