    I suspect if thieves get close enough to my PC to do this, they will just make off with it.

    See also PowerHammer from a few years ago, and several similar power-line based (and fan noise, and VGA cable antenna leakge, and flashing the CAPS-LOCK key, etc) side channel data leakage techniques demonstrated over the last several decades. See TEMPEST for mitigation techniques, many of which predate computers.

    Coil whine: modulates with PSU load in the same way fan speed does. Range is lower due to the higher frequency, but the faster response means a higher bitrate.
