Now we come to the consequences of the immense waste heat of up to almost 350 watts. 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. The card in the open setup would be up to two degrees cooler, which also makes the fan speeds of the closed case drop slightly from the around 2100 rpm to then around 1950 rpm. But we want to stay as close as possible to the real world.
By the way, the fan above the GPU (front, yellow) and the fan on the back (red) are recorded in the curve this time. I have again experimented a bit and the only very 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 one 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 around 40.4 dBA for the RTX 3080 Ti (instead of the 38.8 dBA for the RTX 3080) and a power consumption of up to 340 watts, I measure a still pleasingly low value that is still very noticeable, but quite impressive for a dual-slot card. It’s just that it’s no longer really quiet, but not infernally loud either. Go like this.
However, I do not want to conceal the extreme case. If you use Furmark or heavy GPGPU scenarios, where the memory and the voltage converters are also demanded more, then it’s just under 350 watts, but the fan speeds easily go over 2300 rpm and the noise level is then a whopping 43.2 dB(A). I have not been able to do this with games though. From that point of view, all is right with the world again. If you want to get a first impression of the sound character, I have an audio file (reader’s request) for you to play:
