after setting up two lower fans, the Noctua fansGPU starts making loud whine noises
When I set these fans up - Noctua NF-A12x25 PWM - my GPU reacts strongly. It already has some coil whine, but once I put them in and connected, the fans run smoothly and quietly. Inside the case, however, my GPU starts to emit a noticeable whine. Using these fans on my current system makes the issue even worse; the whine is now intense, almost unbearable, and it affects performance significantly. Even though my old system ran perfectly with no whine, this setup has changed everything. The only reason it didn’t bother me before was its age (three years). I also tried these fans on an older machine I’m selling, and they worked flawlessly there, giving the GPU a clean sound and excellent benchmark results. Now, in my new build, the situation is completely different.
Well, several factors can cause coil whine. It's uncommon for fans to make it worse, but under certain circumstances it becomes a chance. The fans might draw just the right amount of power so the PSU generates more voltage fluctuations, which are mainly what create coil whine. You could be overloading a power rail (unlikely) or pushing the motherboard headers beyond their capacity. Are there any fixes you can try to reduce the noise? Here are some ideas: Are your fans connected directly to a motherboard header? Consider using another header or switch them with a powered fan hub if available. Are both fans sharing the same header? Try disconnecting one or redirecting the second fan to a different port. Do the fans go through a dust filter? Removing the filter might improve airflow and lower power consumption. Remember to reinstall the filter afterward. How are your temperatures when those two fans aren't running? If you're already maintaining stable temps, adding more fans probably won't help and just adds to the whine. Hope this gives you some guidance.
