I bought a PNY GeForce RTX™ 4080 16GB VERTO™ Triple Fan DLSS 3 and since the first day the middle fan is much faster and louder than the other two. It's absurd how loud it is, and no it doesn't sound broken, it's just working too fast. Usually all fans are off but once the card reaches 50 degrees or so the fans begin to work and man does it show. Then they don't turn off until the GPU is at around 25 degrees. The fan is so loud that it's headache-inducing after a few minutes.
Using afterburner or such to change curves wouldn't do anything since it already sounds like that at minimum speed (30%). If I use afterburner to force the fan speed to the maximum, the three fans sound more or less the same. So it seems like, at minimum speed, the middle fan decides to spin at maximum speed anyway. Doesn't this sound like a VBIOS or driver bug? I can't imagine a hardware defect doing this, but I'm not experienced.
