Fan curve and operating noise (“volume”)
Let’s now turn to what is automatically produced when the waste heat is removed: various fan noises. The measurements in the measuring chamber are, as always, a bit tricky, because you can’t measure anything through the closed side window. so later I’ll manually set the fans to the values I measured while gaming and torturing in the closed case and leave the setup open. The approximately 1500 rpm in the gaming loop are audible, but not annoyingly loud. In the stress test, it is up to 1580 rpm, which is also still acceptable.
But what does the measurement for the operating noise show then? You can see nicely from the frequency analysis how the sound carpet splits up. With 31.1 dB(A) in the gaming loop and just under 200 watts in Cyberpunk 2077, none of this is an issue, even though we can again see the harmonics of minimal coil and capacitor buzzing in the range from about 3.7 KHz, but this only occurs at high FPS rates or strong load changes (slight spikes).
It is a tiny bit louder in the stress test, but even that is nothing to make you lose your mind; it is still bearable and barely perceptible when the side panel is closed.
