Huge difference in noise level between ML350 G5 and ML370 G5

Dear all,

Recently, we had a ML350 G5 for test purposes in our office. I noticed that this box was extremely quiet compared to a ML370 G5. Is that possible? Or are there any options to lower to noise level of a ML 370 G5 (i.e. low fan speed profile etc.)?

Many thanks.

Kind regards,
Matthias

Yes, i think this is possible.
If you compare the architecture of the both server you will see, that the ML370 G5 have a "center wall" fan cage with up to 6 fans. The ML350 G5 has not such a "center wall", it has a fan assembly an a headsink for cooling instead.

yes, the newest support pack is installed. But in the meantime, I got some fixes etc. Should I reinstall the support pack?

Thanks,

Fan speed is controlled by the hardware not by drivers, so the fans will run at the default low speed regardless of the support pack being installed or not.

You also may want to take a look at the system setup ("F9" at boot). There's an option to set the standard fan speed.

Can you tell me where I can find this option? I checked already but found something like "Dynamic Power Regulator" only. There was no specific setting for the fans.. Many thanks!

Sorry, I do not have this option: "RBSU (F9) --> Advanced Options --> Fan Speed". Is this setting available for the G5 series as well?

I'm sorry, my fault!
The RBSU for G5 servers doesn't have this feature any more...
P.S.: Bist du aus der Schweiz?

OK - thanks. So no chance to reduce the noise level.. :-(

Ok, dann schreib ich mal schnell auf D.
So ein ML370 ist natürlich nochmal ein Pfund mehr als ein DL350. Er muss zur Not auch mehr leisten. Er hat deshalb ein anderes Layout und auch andere Lüfter.
Das er dadurch lauter ist, kommt fast zwangsläufig. Aber er steht ja eher selten in einem Wohnzimmer...
Liebe Grüà e aus D, Peter
