Mac Pro Late 2013: Anything that can be done about coil whine?
as you are the experts in the field — my Mac Pro exhibits some audible coil whining. I've tried unplugging all kinds of devices and ran the device through another power outlet. I've disabled Bluetooth and WiFi to change power consumption. I've changed the fan speed with iStat menus and tried putting some strain on the GPU and CPU with benchmarks. The noise stays the same: http://cl.ly/3c032O0R3v2a
Any ideas or would you say the noise is within spec? Apple would exchange the nMP for a new one but they are not sure if that would fix the issue...
Es esta una buena pregunta?
