How to Fix GPU Coil Whine: Causes and Sound Dampening Solutions

GPU coil whine is a high-pitched electrical buzzing sound caused by copper inductors vibrating under high current loads on the graphics card. Fixes & Mitigation Steps: 1) Cap Frame Rates: Uncapped FPS in game menus (e.g. 500+ FPS) causes intense coil whine. Limit your maximum FPS in Nvidia Control Panel / AMD Software to match your monitor's refresh rate. 2) Undervolt Your GPU: Using MSI Afterburner to lower GPU voltage by 50-100mV significantly reduces inductor vibration while preserving 99% of FPS performance. 3) Swap Power Supplies: High electrical ripple from low-quality PSUs worsens coil whine. Switching to a clean ATX 3.0 PSU often dampens the noise.
