Too much volume is better than not enough volume right?

I ordered some copper pads that might be thicker than my default thermal pad. Having too much gives flexibility as opposed to too little which won't make contact...?

I have done that do every GPU die I have come across with a pad, it has always run cooler (including my mobo's onboard GPU)

Wait, so if I dissolve the pad & add paste, does that create a pad-paste mix that provides both heat transfer and volume?

At the moment I ordered these copper pads:
"GPU Thermal Pad Copper Shim .01" .25mm Thick"

Would they work better than thermal pads? I assume I need to apply TP to both sides of the copper...

Anybody using copper pads like the one above?

I've used old pennies (Pre-1984 IIRC) on several laptops. They do the trick.

Recent ones are mostly zinc, which is no where near as good a thermal conductor as copper.

Yeah, I forgot to mention that. I beleive that all pennys below the year 1960 or something like that were %95 copper. There were years when the pennys were made out of steel but mostly copper.
