All tests are conducted according to ISO 7779 and declared according to ISO 9296 except 90% CPU. For this mode, the system CPU
was stressed at 90% utilization with no other peripheral device spinning. This test mode is not specified in ISO 7779, but was meas-
ured using the same microphone distances and measurement techniques defined for the other reported operating modes.
