Noise emissions (“volume”) and fan speeds
The fan curves of the MSI GeForce RTX 5070 Ti Vanguard SOC in silent mode are designed to optimally balance cooling performance and volume. MSI again relies on three separate fan controls with slightly varying speeds to minimize resonances, humming and frequency modulations in the audible range. Synchronously running fans can generate mechanical resonances, which are amplified in closed housings and cause disturbing noises. Slightly different speeds prevent these frequencies from overlapping. Asynchronous operation also reduces the so-called “humming” caused by uniform air flows.
Frequency modulations are also reduced, as the fan noise is spread over a wider frequency spectrum and is therefore less annoying. I have averaged the three values and omitted the gaming mode, as with around 150 rpm more it only results in a board temperature that is around 2 K lower. I can live with the approx. 1050 rpm in silent mode.
In the Torture test, it doesn’t go much above 1100 rpm either.
The measurements in the acoustic chamber show that the noise development of the MSI GeForce RTX 5070 Ti Vanguard SOC depends largely on the fan speed. At low to medium speeds, the card remains remarkably quiet thanks to optimized fan blades and low-vibration mounts and is barely perceptible in normal environments.
Although the noise level increases under high load, it remains moderate compared to previous generations. This speaks for improvements in the fan design and cooling strategy. The precise fan control avoids abrupt speed jumps, which reduces annoying acoustic peaks. Instead, the adjustment is smooth, making the noise more even and pleasant.
The measured dB(A) values correlate with the temperature curves, which indicates a well thought-out balance between cooling and volume. In silent mode, the average is only 32 dB(A) and is therefore practically inaudible.
And to round it all off, the comparison of the MSI GeForce RTX 5070 Ti Vanguard SOC in silent mode with the Gaming Trio, which was also tested. All cards run in Cyberpunk 2077 and UHD with 99% load for over 15 minutes. First the Gaming Trio:
Now the MSI GeForce RTX 5070 Ti Vanguard SOC in gaming mode:
The only annoying thing is the coil noise, but this is only noticeable because it is not covered by the fans. Unfortunately, there are no completely noiseless coils, especially as certain manufacturing tolerances cannot be ruled out even with these higher-quality components. A bit of lottery is therefore involved again, unfortunately.
