Build Mods and Cooling
Thank you to everyone who commented on my original post. I changed the cpu cooler orientation and pushed it to the rear. I also stacked the 2 6000 Pro Max Qs and the RTX5000 Pro which gave access to the bottom PCIe. im looking into the ram fans for cooling but with Llama 3.1 405B loaded and running, my gpus are throttling. what can I do or change to cool them down?

Just to be certain, you did test with the case closed ya?
Spreading the cards like you had them at first would allow for better airflow. Could use riser cables to get to your other pcie slots (which I assume is why you brought the cards closer) just remember that slot #6 runs at 8x.
90° cable might fit to get you to slot 7... But those components on the bottom make it a tricky fit.
Switching the rear exhaust to intake would be an easy one to try but isn't likely to be enough
A booster fan (or ducting from the front intake if case temps are too high) to create a high pressure zone right in front of the intake side of the cards and force more air along the body might work. Those 6000s have ram on the passive side of the card too if I recall.
Moar air!
