A good idea would be to take like 5 pennies, one and put it flat on the chip, then put adhesive on the rest of them so that they stand straight up(maybe a tiny drop of superglue as well to make sure they dont fall onto the card itself. It would work just like a normal heatsink instead of just stacking them. Not sure if this will work better, but I would imagine so.
Notice : JUST A THOUGHT!! I take no responsibility if someone owns there card because of this! Also, if you DO attempt this, I would soke the pennies in orange cleaner or alcohol or something. Doubt you wanna smell burning crud after using dirty pennies for a few hours, lol.
