Let’s now get to the consequences of the graphics card warming. Of course I’m interested in the noise level of what is now emitted as complex fan noise. Whether closed or not, the temperature curves look very similar. The card in the closed construction still acts very, very sovereign, whereby the speeds of 1620 rpm remain really bearable. Amazing, but true.
By the way, the curve shows the one tiny bit faster rotating fan above the CPU and the one at the back. I have experimented a bit and the only slightly lower speeds are chosen in such a way that there can be no modulation phenomena when intermodulation suddenly produces audible mixed products that remind you of the oscillating noise of the engines of propeller-driven machines. I could not find any other reason. But that’s smart.
Let us now come to the noise level and the sound character. With approx. 34.5 dB at Witcher 3 in UHD and a power consumption of a good 225 watts, I measured a pleasantly low value, which you can still (barely) perceive, but which is miles away from the 41.9 dB(A) of the GeForce RTX 2080 Ti. A little more than 7 dB difference is already a brutal announcement. The sound characteristic mixes a noise with the engine noise, which is however very broadband. The bearing noises produce a kind of slight peak at approx. 70 and 240 Hz. Nevertheless, you can live with it well, because it remains very quiet overall. In the high frequency range we still see the voltage transformer peaks. The converters are not loud, but you can hear the coils hum more because of the quiet fans.
But I do not want to conceal the extreme case. If you use Furmark or heavy GPGPU scenarios, where the memory and voltage converters are also more demanding, then it’s still a good 225 watts, but the fan speeds go slightly above 1700 rpm and the noise level is then around 37.4 dB(A). However, I have not been able to do this for games. Seen in this light, the world is then also in order again.
