There is a fan stop, the hysteresis is well solved and the fans only rotate when you really need them. Are there still approx. 1350 rpm, it rises to approx. 1422 rpm (max. 1440 rpm in closed construction), depending on the housing and airflow. That is a very good value. By the way, these speeds affect the two large fans, the smaller third rotates even more slowly.
By the way, this is no different with the stress test.
Let's look at the measured values again in direct comparison to the Founders Edition as a tabular listing:
RTX 2080 Super | RTX 2080 FE | |
---|---|---|
Fan speeds Open Benchtable Maximum | 1377 rpm (Gaming, Peak) | 1907 rpm (Gaming, Peak) |
Fan speeds Open Benchtable Average | 1356 rpm (warmed up) | 1897 rpm (warmed up) |
Fan Speeds Closed Case Maximum | 1461 rpm (Gaming, Peak) | 1959 rpm (Gaming, Peak) |
Fan Speeds Closed Case Average | 1422 rpm (warmed up) | 1942 (warmed up) |
Noise Emission (Air) Average | 34.1 dB(A) Average Closed Case, 34.7 dB(A) Peak | 39.6 dB(A), Closed Case |
Noise Emission (Air) Idle | Fan Stop | 31.3 dB(A) |
Sound characteristic / hearing impression | rather noisy, hardly lower-frequency shares | rather noisy, hardly lower-frequency shares |
Coil-feathers/electric noises | very low, with very high FPS numbers and load changes | low, only for very high FPS numbers and for load changes |
Sound Spectrum
The measured 34.1 dB(A) are based on the measured 1422 rpm in the closed housing. I applied the same gaming load to the open set-up in the measuring room, but the fans were set to approx. 1450 rpm in order to be able to adjust this value as accurately as possible. The result is impressive, because the map is really quiet. Despite the waste heat to be dissipated, it is almost 270 watts.
The soundscape is audible and you can also perceive and measure light (low-frequency) engine noise for light noise (see peak on the spectral analysis above). The noise comes from the turbulences of the rotor blades and is defined by an almost metallic noise and siren of the two fans. However, the chirping of the coils is always present (see also peaks at 6 and 12 KHz in the analysis). Thus, the RTX 2080 Super had to offer a slightly higher chirping in the high-frequency range, which probably explains the difference in the measured values.
