I've seen this question a few times, but with no answers yet. We have an m1000e with 8 M610 blades in there. After a migration to a new building, and after powering it up, we've realised the fans seem like they're at full power.
All fans and PSU's are in operation, the redundancy is 'power supply redundancy' ..although changing this seems to have no affect.
All 8 are running at 14000RPM, which seems high?
Aside from downing everything, does anyone know what might be causing this?
I noticed similar behavior with blades m620. But after updating the CMC (5.01), BIOS (2.5.2), iDrac (2.10) and switch inside enclosure (I cant remember the version and model) the speed back to normal.
