Let’s now turn to the consequences of global warming of graphics cards. After successfully preventing the GPU pole caps from melting, I am of course interested in the noise level of what is now emitted as complex fan noise. Whether closed or not, the temperature curves look very similar. The card in the open design is one to two degrees cooler, which also reduces the fan speeds of the closed case from around 1896 rpm to approx. 1840 rpm slightly lower.
The difference is measurable, but not audible. By the way, the curve shows the fan above the CPU that rotates a little bit faster. I have experimented a bit and the only slightly lower speeds are chosen in such a way that there can be no modulation phenomena when intermodulation suddenly produces audible mixed products that remind you of the oscillating noise of propeller engines. I could not find any other reason.
Let us now come to the noise level and the sound character. With approx. 38.8 dB at Witcher 3 in UHD and a power consumption of a good 330 watts, I measured a pleasantly low value, which you can still perceive very clearly, but which is far from the 41.9 dB(A) of the GeForce RTX 2080 Ti. Slightly more than 3 dB difference is already an announcement. The sound characteristic mixes a noise with the rather low frequency engine noise, which is very broadband. The bearing noises produce a kind of slight peak at approx. 260 to 270 Hz. Nevertheless, you can live with it well, as it’s not easy to tame a dual slot card with 330 watts of waste heat.
But I do not want to conceal the extreme case. If you use Furmark or heavy GPGPU scenarios, where the memory and voltage converters are also more demanding, then it’s still a good 330 watts, but the fan speeds go slightly above 2000 rpm and the noise level is then a whopping 42.7 dB(A). However, I have not been able to do this for games. Seen in this light, the world is then also in order again
