There is no fan stop, the fans also run in the idle with 30%, which corresponds to about 1500 rpm. The threshold value for the increase is between 64 and 65 degrees, which can also be seen by the curves. With around 3041 rpm, the fan under 3D load is already audible, but as rather unobtrusive noise. There are quite other construction sites, as we will see in a moment.
In the stress test, the curves look very similar, even if the fan increases slightly to over 3070 rpm.
Let's look at the measured values again in direct comparison to the Founders Edition as a tabular listing:
Nvidia Quadro RTX 4000 | |
---|---|
Fan speeds Open Benchtable Maximum | 3028 rpm (Gaming, Peak) |
Fan speeds Open Benchtable Average | 3019 rpm (warmed up) |
Fan Speeds Closed Case Maximum | 3041 rpm (Gaming, Peak) |
Fan Speeds Closed Case Average | 3058 rpm (warmed up) |
Noise Emission (Air) Average | 42.4 to 42.8 dB(A), Closed Case (Peak) |
Fan stop |
30% minimum speed (approx. 1500 rpm) |
Sound characteristic / hearing impression | noisy, restrained, light engine noise |
Coil-feathers/electric noises | Audible |
Sound Spectrum
The measured 42.6 dB(A) are based on the measured 3041 rpm in the closed housing. We have placed the 3D gaming load on the open set-up in the measuring room, but the fans are limited to approx. 3040 rpm in order to be able to adjust this value as accurately as possible. The result is impressive, because you don't hear more for the performance offered than with other workstation graphics cards.
However, what gnaws at the nerves a little and is also very visible in the spectrum as a yellow area are the chirping voltage converter noises, which can still drown the fan a little. By the way, a counter-test without any load, but with the same fan speed, certifies the card with a maximum noise level of only approx. 41.4 dB(A). That is quite a difference. By the way, this "coil-feather" iet a little more dominant with the cold card, so that you get once again the appropriate proof that too cold coils are not good (for the ears).
