I'm having fan speeds and noise level issues from my most recent batch of HP ProLiant DL380 G7 servers. Most of the systems are nearly silent with low fan speeds (as reported by
hplog -f). The majority of systems causing issues are running an operating system that cannot accommodate the HP Insight Management agents or drivers (NexentaStor 3.1). I also have a few CentOS servers running the HP drivers that have the same issue. Some of these systems have 2 or more PCIe cards installed.
Is there any way to force a lower fan speed on these servers? I've seen the advisory on the BIOS cooling option. I'm more curious about the random nature of the issue and if there's any means to control this via software.
