Just got the memory water cooled. The temps went from 80-90C to 40C under load in benchmarks!
The cool fact is, I got faster numbers consistently on this test. So the RAM temps were slowing it down:
If anyone is interested, I’ve open sourced the design files for the heatsinks which fit any DDR5 RDIMM here: GitHub - galvesribeiro/ddr5-rdimm-heatsink: DDR5 RDIMM heatsink design files
Now All its needed on this build is the 2x RTX 5090 and its respective blocks
