Sapphire Radeon RX 7900 GRE Performance, Power Analysis & Noise Output

Noise Output

Fan Full Speed, 75% & 50%

At full speed noise is low, while at 75% and 50% settings, it is on the high side.

Idle, Multimedia & Rendering

Thanks to the fan-stop feature, most graphics cards are dead quiet at idle and multimedia. The RX 7900 GRE Pure is also quiet in rendering, keeping its noise below 18 dBA.

Furmark

Even in a long Furmark run, noise doesn’t exceed 18 dBA. The cooling system of this card easily handles the thermal load.
