Fan curve and operating noise (“loudness”)
Now we come to what automatically arises when the waste heat is removed: various fan noises. The measurements in the measurement chamber are, as always, a bit tricky, because you can’t measure anything through the closed side window. That’s why I manually adjust the fans later to the values I measured during gaming and torture in the closed case and leave the setup open. The just under 1600 rpm at a little over 160 watts is barely audible. That’s quite good at first.
But then what does the measurement for the card? You can see nicely in the frequency analysis how the sound carpet splits up. With 30.9 dB(A) in the gaming loop, none of this is an issue, even though we can again see the minimal harmonics of coil and capacitor buzzing in the area from about 4 KHz. But it’s not really much this time. The fans are a bit buzzy in the lower frequency range, but you can barely hear it really. So it’s nothing that would be acoustically distracting.
Coil Noise: “Coil Whining”
We still have to talk about one point and that is once again the annoying coil whining, even though it turns out pleasantly low here and is only audibly noticeable at FPS rates above 300 FPS and during hard load changes. I already wrote that the card spits a bit in the load peak measurements. Especially since the six phases have to work hard. As always, you can find more about this topic here:
