My ram got very hot to the touch. Before I water cooled it with full cover block I used a Swiftech MCW82-7900 gpu only block with the stock 1 piece heat sink that covered all the vram and the memory VRM.
This is what it looked like with the stock PCB heat sinks and the Swiftech MCW82-7900.
I think SApphire did a good job by separating the main VRM heat sink from the RAM/memory vrm heat sink. I think the heat from the RAM and the VRM gets trapped in the heat sink and by separating the heatsink the ram and VRM can cool down faster.
Since I put Fujiply xtreme thermal pad on my VRMs and vram my card over clocks better and the VRM temps are cooler. The ram gets very hot to the touch. Felt hotter than my VRMs.
I think the best way to cool the VRMs and vRAM is either to put a well designed water block on them with high quality thermal pad or put individual heat sinks on each vRAM IC and VRMS.
My card with fujipoly xtreme thermal pad and Coolaboratory Liquid Pro on it. Water cooled with Heatkill block. Lots of photos.Warning: Spoiler! (Click to show)
