Let’s now look at the consequences of graphics card heating due to the electrical power consumed. Of course, I will later be interested in the noise level of what is now emitted as complex fan noise. Whether gaming or torture, the temperature curves look very similar. The card in the closed configuration acts very confidently, with the revs only varying around 1200 rpm in both scenarios. The control is semi-passive and you can now see why the temperature curve starts so sharp. The fan remains off up to 64 °C and there is also no extra switch-on pulse. This is elegantly saved by this tip. Smart, as nothing howls.
Now we come to the noise level and the sound character. With about 31.6 dB in the gaming loop and about 130 watts, I measure a really low value that you can’t perceive individually out of the case. The sound characteristic mixes a barely audible noise with the just measurable engine noise (about 170 Hz), which, however, completely disappears next to the lower-frequency peaks towards the top. The bearing noises create slight peaks, but you can’t really hear them. You can really live with that, because it remains very quiet to almost inaudible overall. We don’t see any clear voltage transformer peaks in the high-frequency range, but only slight hints from about 5 KHz.
