When you hear cricket like high pitched irritating noises coming from your graphics card (GPU), less often from power regulation modules (VRM) of motherboards and power supplies (PSUs), that is coil whine. This happens in almost all electrical devices, usually at a frequency and volume that’s inaudible to humans, especially inside a case. In some cases, you can hear the pitch of the coil whine change as the GPU draws more or less power, especially often at very high framerate situations.
