I'm not so sure. I looked at the spec for a current samsung pc333 ddr
512Mb chip, and it works out to about 16W per GB. I think most people
still have 512MB dimms, and probably pc266 (13.6W/GB). I don't really see
why a dimm would have trouble dissipating ~20W, considering its size.
I suspect dimm heatsinks are actually a fashion statement inspired by the
heat-spreaders found on some rambus rimms (which were *spreaders*, a
consequence of how rambus does power management...)
personally, I'm waiting till I can invest in peltier-cooled dimms ;)
