TA-1099: Fans Running at Full Speed on Intel® Storage System JBOD2000 Family
Technical Advisory 1099 (PDF) 
When two power supplies are installed in the JBOD and one experiences a power failure, all the fans ramp up to 100 percent speed. This causes no impact in the operation; only acoustic will be higher than desired. JBOD systems with a single power supply are not affected. This issue is fixed in firmware 13.0.15 or later.
