As a workaround I've built 4 raid arrays with one disk each. Upgrade the firmware. That fixed it for me - I run JBOD and the fanes are nice and quiet. Noisy on boot, like all HP servers, but then settle down when the OS starts. I have this positioned under my TV and low noise was the main reason for choosing it. Of course, getting the firmware upgraded means finding an HP firmware maintenance DVD image from somewhere, as they restricted downloading them. -pete.
