A while back, people talked about how heatpipe orientation might affect CPU thermal performance for asymmetrical die layouts on non-monolithic CPUs. Given that AMD Ryzen takes the multi-chip approach to CPUs ("chiplets"), and that its lower-end SKUs only have a single chiplet and single I/O die, the heat sources for these chips would be off-center and imbalanced toward one side. That's where the initial idea arose. The question is whether that has any relevance once you get to the heatsink level, or whether any differences are meaningful (if even measurable).
In this benchmark, we'll be looking at how the Noctua NH-U12S, Noctua NH-U14S, and Noctua NH-D15 air coolers perform on AMD Ryzen chips when rotated in their two different directions. The GPU was accounted for and eliminated as a variable, as discussed in the content, and airflow was run from the EPS side in to the GPU side out (with the GPU in the lowest possible slot and as a half-height card).
