In case anyone is wondering (via Wikipedia): In 2004, Adi Shamir and Eran Tromer demonstrated that it may be possible to conduct timing attacks against a CPU performing cryptographic operations by analysis of variations in its humming noise (that is, its high-frequency humming noise, not the louder low-frequency humming of its cooling fan). http://people.csail.mit.edu/tromer/acoustic/ http://people.csail.mit.edu/tromer/acoustic/
