Now let’s look at the consequences of global graphics card warming. Of course, I’m also interested in the noise level of what is now being emitted as complex fan noise. Whether closed or not, the temperature curves look very similar. The card in the closed configuration still acts very, very confidently, with the revs only just below 1000 rpm! Amazing, but true, so you can hardly hear them despite prolonged full load. The start-up pulse and the leveling of the fan control are also clearly visible.
Now let’s move on to the noise level and the sound character. With about 33.1 dB and a power consumption of plenty of 160 watts, I measure a very low value, which can still be noticed, but which is absolutely not disturbing. The sound characteristics mix a barely audible hiss with a slightly growly engine noise, but this disappears completely towards the top. The motor produces a kind of slight peaking in the low end and lower mids. Nevertheless, you can live with it very well, because it remains very, very quiet overall. In the high frequency range we see slight voltage transformer peaks, which was to be expected. The converters aren’t loud, but you can definitely hear the coils chirping audibly at least sporadically because of the quiet fans, especially at high FPS numbers.
For control I still have the MP3 file of the soundscape for you, which I simply recorded at the measuring microphone in the chamber. You really have to listen carefully:
