And what about the direct and indirect consequences of heating due to the electrical power absorbed? 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 speeds varying less than 100 rpm in both scenarios. Amazing but true, nevertheless 1800 rpm and more is not an inaudible task even for the Suprim X’s fans.
You can see from both curves that the otherwise typical start-up impulse is missing. This then also eliminates the moment of shock when the propellers come to life.
Now we come to the noise level and the sound character. With about 33.8 dB in the gaming loop without the fans started, it’s mainly the voltage converters where the coils emit an oscillating chirp at about 1.6 kHz. This is not extremely loud, but it is audible without a working fan. But don’t worry, it doesn’t take long for the cooler to warm up enough for the fans to start up as well.
With the almost 40 dB in the gaming loop and about 500 watts is still an acceptable value that can be perceived well from the case. The sound characteristics mix an audible but not annoying hiss with the just measurable, slightly growling engine noise (around 160 Hz), which, however, completely disappears next to the lower-frequency peaks towards the top. The bearing noise produces slight peaks, which can be easily recognized on the graph as recurring, brighter stripes. However, you can live with that because it remains tolerable overall for the waste heat to be dealt with. We don’t see any clear voltage transformer peaks in the high-frequency range; all that is simply lost in the fan noise.
