When comparing one card to the other, the differences become abundantly apparent; not only does the 55nm card have a shim around the IHS but the PCB itself is slightly longer by a few millimeters and there is a distinct “bulge” in it closer to the rear. There are also noticeable differences in the power distribution and voltage regulation sections due to the different electrical needs of the new core.
For those of you wondering; the mounting holes around the core are the same on the new card are as the outgoing product. Therefore, any compatible heatsinks or non-full coverage water blocks should fit without a problem. However, full cover water blocks will not be compatible due to the different layout of the VRMs.
I want to watercool my GTX260 55nm and it will probably be some time before a compatible hardmounted heatsink will be avaliable.
I was thinking about taking a D-Tek UniSink:

Or a Swiftech GTX200 Heatsink:

If I saw off the VRM end of the heatsink, the rest of the heatsink will still cover the memory and that single IC fine. Then, I could then use a few RAMsinks for the remaining VRM. Does this sound reasonable?
Does anyone know if the D-Tek UniSink has raised area for each memory module or is it just a thermal pad?
Does anyone have a picture of the Swiftech GTX200 heatsink bottom?
