Re: New 9009-41G fan noise

Hi Gary

You should perhaps (re)check with IBM

In our case the issue arose with installation of a new P9 server.
IBM said that the Hi rev fan was needed for a certain big-cache disk
controller.
We kept nagging IBM's Hardware CEs and after several months a new
firmware version was released and solved the issue.

Thanks Gad. According to IBM the latest firmware is the reason the fan
is running as load as it is. This server has NVMe storage and i guess
there was an issue with heating so the latest firmware runs the fans
faster to help cool the modules.

I suggest you get a newer version of (Service processor) Firmware.

subject: New 9009-41G fan noise

We have a new 9009-41G (tower) that we just powered on the other day.

The

fans have been running non-stop since the server was powered on. The

server

has 2 1.6tb NVMe storage cards. I'm wondering if anyone on the list is
experiencing the same thing.

I opened a case with IBM and their response was " A problem was fixed

for

certain PCIe adapters and NVMe U.2 devices. The following feature codes

are

affected and the presence of these features in the 9009-22G, 9009-41G,
9009-42G, and 5105-22E servers can result in higher fan speeds and
therefore higher acoustic levels after upgrading the firmware". I'm

just

trying to determine if the fans are supposed to be running continuously.

Thanks in advance for any hindsight that can be provided.
