For our temperature testing, we measure the peak memory temperature under load. A reading under load comes from running Metro Exodus Enhanced Edition for 30 minutes.
In a similar fashion, GDDR6X thermals are definitely higher than what we'd expect, with the Silent BIOS hitting 82C, compared to 78C for the Gaming BIOS – making these results higher than both the Palit GameRock OC and the Inno3D X3 OC. We asked MSI about this and they told us our results are in-line with their internal figures, and it seems that the higher temperatures are a result of the AIO block not flowing liquid directly over the memory modules – rather, the memory contact zones actually raised slightly from the copper baseplate.
Again, to be clear these results are still perfectly fine and well within safe limits. For a liquid-cooled card however, we would have expected better.
