DL360 G2 - How to adjust internal fan speed

[Andrew_351]

DL360 G2 that I recently updated to the latest firmare (Smartstart 7.40) and rebuilt with 2003.

The problem is the fans run at full speed when the unit is started and never decrease regardless of Windows loading or not.

I could swear the fans slowed down a bit after windows loaded 2000 server, but now they run at full speed.

Can anyone point me in the right direction? Server is an A/C environment and has the latest BIOS updates and was rebuilt using the smartstart (7.4) CD.

Thank you!

Check the environment page of the HP Systems Management Homepage to confirm your assumption that the fans are at high speed. Fan speed is under control of the Advanced System Management Controller driver and are adjusted automatically based on what is required to keep the system cool. If the ASM (also known as 'health') driver is not present, the fans will spin only at high speed.

Thank you for the response!

The environment page says "CPU Fan status: HIGH" "Power Supply Fan: NORMAL".

I continue to try and install the "Advanced System Management Controller Driver" from the smartstart CD, but it never installs. When I looked on the site for downloading, the DL360 G2 model is not listed as a supported server for this driver. I guess this is why it is not installing.

The one for iLo is installed fine.

Any other suggestions? Maybe I should try putting Windows 2000 Server back on this...

Thanks

Hi,

Please visit the following site

HP ProLiant DL360 G2, Microsoft Windows 2000

Update the system driver and BIOS then check
If it is failing then update with the error message.

Bios is at Version P26.

Ran the PSP and updated everything with SS 7.4. Is there any driver in particular I need to be looking for?

I rebuilt the entire machine with Win2k and fan speed is still set to "high".

Any other ideas?

Thanks very much for the help!

Hi Andrew,

Just a quick check, do you have any amber LED lit up on the front chassis upon booting into OS?

Cheers!!

No, all green lights.

HP is going to send out a new fan. They said the temperature reading and everything looked fine. -not sure why it is stuck on high for CPU fan.

If the new fan doesn't work, then they will send out a system board.

Just hope to have this fixed, it is way too loud right now...

[Terry Hutchings]

This machine doesn't have any hardware based fan control. The fans will normally never slow down until the correct system mgmt driver is installed. This server uses the "HP ProLiant iLO Advanced and Enhanced System Management Controller Driver for Windows 2000/Server 2003" (CP005397.exe). This is the correct driver for any machine which has an ILO. If something is preventing this driver from loading, then this would account for why the fans never slow down.

[Andrew_351]

Thanks...

It appears that this driver is loaded. Inside device manager, under controllers, it has the correct driver number and no error messages.

Maybe it is a hardware problem afterall...

[Andrew_351]

Well the system fan and the board where replaced and still the same problem. CPU Fan stays on "High" and never slows down.

HP says they duplicated the problem in their lab and it must be the way the system was designed, to always stay on high speed.

Does anyone have another DL360 G2 that they can confirm always stays on high fan speed?

Thanks

Andrew:


You mention that the bios is at P26, but do not mention a date. "P26" is just the type designation HP uses for the DL360G2 mobo. The latest P26 firmware available is from 5/1/2004. Can you confirm?

Make sure your iLo firmware is up to date as well... should be at ver 1.82.

Here is the support page for easy reference...

The Bios is set at 5/1/2004

The new system board had older firmware on the iLo, so that is now set at 1.82.

Still doesn't make a difference.


I really appreciate the help!

Do the DL320 G1's have variable speed fan on them? Or are they also stuck at high fan speed like this one? This unit is ridiculously loud, I would say its about 5x as loud as the ML350 G3 in the rack.

[Cameron Todd]

My DL320 is very quiet. Quieter than a well behaving DL360, let alone a screaming one running at full speed.

It doesn't have the number or high rotational speed performance of the fans in DL360's though.

The only input I can make on this is that we have a DL360G4 which powered up to the full speed situation new until we loaded the Health Management Agents, then it dropped down to a manageable noise level.
