System Board (Mainboard)
The whining sound is caused by high-frequency mechanical vibration of the inductors in the Voltage Regulator Module (VRM) circuitry. Under high electrical load, the electromagnetic forces cause the internal copper coils to vibrate against their casing. Since these components are surface-mounted and soldered to the motherboard, the entire board must be replaced to provide a unit with better-dampened or higher-spec inductors.
