Now let’s move on to the consequences of graphics card warming. So of course I’m 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. That’s still commanding, if already on the upper edge of acceptable. With just under 2000 rpm, the fans are already rotating well, even if there is still a lot of room for improvement. But audible it is.
By the way, the curve shows the fan above the CPU spinning a teensy bit faster and the one at the back. I experimented a bit and the only slightly lower speeds are chosen in such a way that no modulation phenomena can occur when intermodulation suddenly results in audible mixed products that remind you of the oscillating noise of the engines of propeller machines. I could not find any other reason.
Now let’s move on to the noise level and the sound character. With about 41.8 dB(A) at just under 300 watts, the card is already quite loud when compared to the only slightly slower GeForce RTX 3070 FE and its exemplary 34.5 dB(A) at a power consumption of only 225 watts. Unfortunately, the GeForce RTX 3070 Ti is almost exactly on the 41.9 dB(A) of the GeForce RTX 2080 Ti. A little more than 7 dB difference is already a brutal announcement. The sound characteristic mixes a hissing noise with the strong engine noise, which however is very broadband. The bearing noises are also audible. In the high frequency range we still see the voltage transformer peaks. The transducers are not loud, but you can hear the buzzing and chirping quite clearly.
We recorded the appropriate audio sample directly during the measurement process.
