DL380 Fan Noise

[Mario Rimann]

We've got our first DL380. Everythin works fine - but theres one problem: All Fans are on full-power, all the time. This causes noise!

How to stop this noise? Or at least bring it from "extreme loud" to "loud"?

We tried installing the newest Management Driver - did'nt change anything. Is it right, that the fan speed is set by driver?

[Sunil Jerath]

Hello Mario,
Please make sure that the bios is uptodate. You can to F9 and set the fan speed there.

Regards,

[Mario Rimann]

Thanks for your answer!

BIOS is up-to-date (downloaded and installed today).

Where exactly after pressing F9 can I find this option. I couldn't find it yet...

@ boot time

[Stuart Browne]

What OS have you installed on the DL?

I know on the ML's, it's a job for the mangement and monitoring tools to dune the fan speed..

[Renne Cavanaugh_1]

Did you try to install the latest version of Compaq's Advanced System Management? It works for the ML370s - calms that fan right down!

Thanks for all responses to my question!

Olivier: I thought that it's at boot time. At the moment where I'm getting asked if I want to enter System Menu, did you mean this? If yes: I can enter the menu - but I'm not able to find the option to control the fans.

Stuart: I tried installing Windows 2003 Server, Standard. I read about this software-controlled fans. But as of customer note (CN0354W) the DL380 G3 should also have hardware controlled fans. The control ist then overtaken by the driver if loaded.

Renne: I tried this. But I'll begin again by re-installing Windows 2003 Server. Then I'll try to install the drivers again.

Hello!
I have also dl380 g3 with the same problem.
I have on it RedHat 9 and i also installed
hpasm-7.0.0-22.rhel3.i386.rpm.
Hpasm starts ok and when i do a "cat /proc/cpqfan" i see that the speed is low.
However, speaking of noise i cannot say the differnce between now and before, because meantime i moved dl380 to the equipment room and there are a lot of noise in there.:-D

Hi,

Nothing much to add
Just want to confirm do you have Support pack 7.0 installed on server.

If no then do it

Hi,

I downloaded the "Support Pack for Microsoft Windows Server 2003", v7.00 A

I re-installed Windows 2003 Server and first installed this support Pack. But nothing changed. The noise is still the same (also after a reboot).

I can't hear any change in the sound of the machine. When i start it up, it starts doing noise. And this noise never changes! Only if i switch the machine off. But when it's running, its always the same noise!!! There are no differences in the sound (faster or slower fan-speed)...

Regards,
Mario

Hi,

As per the trailing mail i have folowing inputs :
There are diff Zone in server
Zone 1 CPU area.
Zone 2 power supply area.

Have we checked by opening the server which zone we are facing the more problem. Any erros reported in IML for FAN ( I Guess it would not be there )

What is the processor speed:
Because there are diff part of fan for same
CPU fan 92 mm, 74 CFM 159203-001
CPU fan 92 mm, 110 CFM (1GHz) 216472-001

Confirm the part nos as which fan making more noise.

Reagrds,

Confirm the part nos as which fan making more noise. Because Each fan has two outputs; a Presence and Fault signal line that are monitored by the Advanced System Management sub-system. So we need to work in specification to work with this one

The DL380G3 uses a high speed fan design which is much louder than the previous G2 models. Per customer notice CN0354W these fans are running at the lowest setting when they are started.

You should notice when you first apply power the fans go high for a very quick moment then shift down to the 'normal' speed. Yes they are much louder than the G2's but this is by design

Hope this helps

Hi all!

Thanks for all the help!

Last week I called the HP Support. I was told, this noise is "normal". There is Fan-Control planned for a later BIOS-Release. But at the moment, there is no possibility to hardware-control the fans.

Also there is no option in the RBSU regarding the Fans. I heard about setting it there - but no one could tell me exactly on wich point in the menu it is.

Regards
Mario

The BIOS setting may be how HP is going to allow you to adjust the speed in the future. I don't see them being able to modify the 380G3 like they did with the 360G3 Pigtails.
