FAQ: There are claims that on Ryzen 3000 CPUs, the orientation of the heatpipes over the Dies leads to varying processor temperatures, is this true?

Noctua has conducted internal tests with various coolers and CPU samples to find out whether or not the orientation of the heatpipe layout has an effect on cooling performance when used with Ryzen 3000 CPUs. The results have shown no evidence that this is indeed the case. However, as there can be minute variances in surface shape both with the CPU heatspreader and with the base of the cooler, it is possible that one orientation has a better fit than the other and hence gives slightly different results. A different orientation of the cooler also changes the airflow within the chassis though, and this can cause different temperatures as well.
