Noise reduction techniques and speed control parameters
Noise reduction techniques and speed control parameters
I recently purchased a new motherboard, the Gigabyte Z790 UD AC, and I'm experiencing noticeable coil whine. It alternates in and out, making the noise more bothersome than a steady hum. I tried adjusting the Acoustic Noise Mitigation in my BIOS, but there are two slew rate options—2x-16x. I’d appreciate any guidance on what each setting does before I make changes.
I can clearly verify that it affects sound from the motherboard. I experimented with various configurations and it significantly reduced coil whine, making it nearly imperceptible. However, I haven’t identified any drawbacks or unintended consequences. Running 3D Mark before and after showed no change in the score.
I used x8 and it works well in my situation, though not perfect. In a typical office setting like working on Windows, it doesn’t stand out. Under heavy use it gets worse sometimes, but not constantly.
