Ram fan conundrum:
A. I like silent and those fans sound like turbines
B. They won’t fit due to proximity of video card slot, I tried a few
I did buy pure copper heatspreaders and 10 packs of the pad minus 8 thermal grizzly.
I don’t like using the included two sided tape because if you reseat it or try to take it off Theresa good chance you’ll just rip chips right off the ram pcb.
And, the tape is not very thermally conductive.
The minus 8 Pad 1mm and very heat conductive and electrically inert. And isn’t sticky.
At 1mm it’s two thick tours on the heat spreaders, so i’m going to run it through a lasagna press and squish it down to .5mm (and doubling the area it would cover. Then it should be a solution.
LRDIMM best heat spreader design I can come up with :
So here is the process I went through to use pure copper heatsinks, no adhesive, and thermal ceramic clay.
6 of these ceramic clay and wax paper:

lasagna press to reduce 1 mm TIM to .5 mm and gain area.

Dimm Temps
medium low use / idle temps / checking mail / being on this forum temps:
about 42 C average across 12 LRDIMMs
and this concludes the experiment. some observations:
under load the LRDIMMS still get warm / hot but 13C less than before.
after a workout, the dimm temps stay higher longer due to the amount of mass / heat retention added by the ceramic clay and the copper sandwich.
seems to be an improvement overall.
