I've just installed a Scythe Musashi and I'm using stick on copper heat sinks on the VRM's and memory. I'm getting around 35 – 37C idle on the GPU and the VRM's, which I'm assuming are labelled as VDDC Slaves in GPU-Z, are idling at around 49C and have gone up to about 80C after an hour of Far Cry 2.
I added a copper sink to the little black chip just above and to the left of the fan connector as it was labelled VTT so I assumed this was also a VRM? The thing ids though, after taking the stock cooler off, I noticed that the plate wasn't making much contact with the VRM's.
The card is really flimsy without the stock cooler on it and I may end up adding the red bracket from the stock cooler just to improve the rigidity of the card, this would mean removing the stick on copper ram sinks though.
Here's a shot of the fitted cooler.
Would the Copper Ram sinks off the 3870 cards fit on the 4870, eg would the screw holes line up? I know the top left ram position is slighty different between the two cards but I'm temted to buy a faulty 3870 off ebay just to salvage the copper ram sink.
