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 measured using the same microphone distances and measurement techniques defined for the other reported operating modes. 6 Declared Sound Power rounded to nearest tenth of a bel per ISO 9296 section 4.4.2 38
