Hi,
I am preparing a UCS C220 M4 with windows 2012 for a client.
The server is extremely noisy, I mean much more than any other rack server I have ever seen.
All the fan are working at highest speed rate as if the server had to urgently cool down.
The question is: Is this normal ? Is the server broken ? Is there an option to lower the "fan-policy".
And how is this done.
Best regards,
Javier Conejo

Hi Javier,
Do you have just one cpu?

Yes, only one CPU.
The bug seems to be reported, but with no solution yet it seems.
I will try what Kenny is proposing !
Thanks !

The fan policy can be lowered if you go to the Server> Power Policies> Fan Policy.
Here is the explanation for each option:
http://www.cisco.com/en/US/docs/unified_computing/ucs/c/sw/gui/config/guide/1.5/b_Cisco_UCS_C-series_GUI_Configuration_Guide.151_chapter_011.html#concept_8CB787DF70304E98BE25D120466418B9
There are still some PCIe cards that cannot be monitored and cause the policy to be "ignored" so the server can be kept cool (I'm not saying that is your issue, I am just mentioning it)
Open an SSH session and enter the commands:
"connect debug-shell"
"sensors"
Paste the output here for the FAN sensors (they will have the word "FAN" on it)
Be sure you air flow is not blocked at all by doors or cables.

I just tried this and it works. Thanks.
But It is a BUG of the server, so the second answer is also correct.
This is really a bug since the server only has one CPU and no added PCI cards, just the two that come with it. The LAN and the Raid.
The balanced fan policy is suposed to work from sensors, and I had to change it to low power manually.
