Fan control and curves
Cooling only works with a proper airflow and that’s why I took a look at the fan curves. For this purpose, I measured both BIOS variants for the card. You can see at the beginning of both graphs the switch-on pulse for the semi-passive fans, then the increase to some kind of safety level and after that the control of temperature vs. fan speed. You don’t have to understand AMD’s “fuzzy logic”, but it at least ensures that the cards are still (too) well cooled even during load changes at the beginning.
Noise emission “Volume
The initial revving up to 1600 rpm is articulated in a sound wave of around 39 dBA, which is still significantly quieter than the MSI RX 6950 XT Gaming X Trio sweating under full load.

Then it gets significantly quieter with a longer runtime under full load. The downside, however, is that you can now easily hear the buzzing of the coils. Well, you can’t have everything and the good Mr. Lorentz and his power named after him are unfortunately a bit in the way acoustically. But it’s nothing to kill yourself over.

Even the almost 35 dBA in the performance BIOS are acceptable for such a hot card, and the 32.6 dBA in silent mode are really silent. As an interim conclusion, we can state that Sapphire has created a cooler here that cools very well as a total package and also remains acoustically up to date. This can only be praised.
