HP ML350e Gen8 Fan Noise

Been configuring a new ML350e Gen8 Server.

 

Updated the iLo and BIOS to the latest version and have installed a FAN Kit so that I have four fans in the Server.

 

The fan noise form this Server is very loud and at present while I'm working on it I have had to put it a cupboard to try and reduce the noise in the office as it just too load to work in the same room as it.

 

Is there anyway of reducing this noise ?

 

I have seen this problem before on other Servers and the iLo and BIOS updates have usually fixed this problem, but not in this case.

 

Thanks.

Same problem with ML350p Gen8.

 

The server is in an air conditioned room, has three fans and all BIOS/Firmware upgrades but the customer is complaining about the noise. When idle is seems to have a hum but often the fans rev up a bit making it even louder.

 

System has 64GB Ram, 8 x 10K SAS drives and the CPU rarely goes above 10% usage. The previous server was an ML350 Gen5 with 8GB Ram and 6 x 10K SAS drives and hardly makes any noise at all.

Hi

 

I have the same problem on my ML350e Gen 8. But i have no additional Fans installed. Would it be better if i install the two additional Fans?

Hello

 

I am having this same issue.  Fans are running at %100 all the time with not load on the server.  BIOS and iLO updates did

not fix.  Has anyone found a solution to this issue?

Re: HP ML350e Gen8 Fan Noise

I have the same problem with my ML350e Gen8.  I am running Redhat Ent 6.2, and I I have installed all of the Linux drivers in the SPP.  I can monitor the status of the fans from both the command line and the ILO interface.  I have two fans and they are running at 50% -- sounds like a vacuum cleaner sitting next to me.

 

If I install Windows the fans go silent (10% speed).  If I boot into the Smart Controller Utility (which appears to be running an embedded Linux) the fans go silent (10% speed).

 

I don't understand why my fans constantly run at the higher speed when I have RHEL6 installed with the latest SPP drivers.  The server temps are not elevated.

 

I need to get this server running, preferrably on Linux, but I can't have the constant fan noise in my work environment. 

 

Any solutions or clues that I can pursue?

Hello

 

I found a Solution for my Server.

 

I removed all additional PCI-E Cards and build in the Redundancy Kit (with additional Fans) for this Server. After that the Speed of the Fans reduces the speed to 7%.

I have the same problem... the server has been running for a little more than a month...

 

And today I did a full Windows server backup and installed a Startech USB 3.0 PCIe card, the server is still running fine after this part.

 

 

After I installed the PDF convertor 8 and Office 2013... and a restart... it is still fine...

 

But after a while... the fan start acting up, it is running up and down which is very annoying, I am totally fine if it is running in a constant speed(with noise).

 

Most importantly, the cpu usage is less than 5% all the time, it is jumping between 0-4%.

 

I am just glad that I am not the only one who has this problem... because I usually have bad luck with me...

 

 

 

EDIT:

 

 

A HP rep. get back to me within 1 hour after I submit the request, but... he recommends to remove the StarTech's PCIe card... 

 

I will wait until Wednesday and see...
