HP ProLiant DL120 G5 FAN issue and replacement

[dingy]

 Hi,

We recently found out our HP ProLiant DL120 G5 is making a lot noise and the following critical alarts are logged in ILO Monitoring Sensors:

 Fan  CPU FAN1 Rotor1  Upper Critical  14880.95 RPM  
 Fan  CPU FAN1 Rotor2  Upper Non-recoverable  14880.95 RPM  
 Fan  CPU FAN2 Rotor1  Upper Non-recoverable  15873.01 RPM  
 Fan  CPU FAN2 Rotor2  Upper Critical  14005.6 RPM  
 Fan  SYS FAN1 Rotor1  Upper Critical  15873.01 RPM  
 Fan  SYS FAN1 Rotor2  Upper Non-recoverable  14005.6 RPM

I understood that there were 3 dual-rotor fans installed in the server. I need to order new fans to replace those broken ones. My question now:

1. Are these 3 fans the same part number? (CPU FAN1, CPU FAN2, SYS FAN1)

2. Is it easy to replace these 3 fans?

I did initial research and found the links below:

It shows how to replace system fans but not CPU fans and couldn't find out where CPU fans are located and their part number.

Please help.

Regards,

Hi,

personally I prefer the 'service and maintenance guides'.

http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang=en&cc=us&docIndexId=64180&taskId=125&prodTypeId=15351&prodSeriesId=3683232

You can find the one for DL120 G5 there.

And the service media library: http://h20464.www2.hp.com/index.html

The videos are nice and it looks very easy to replace the fans.

There is no fan directly over the CPU, just a heatsink.

The fans are all the same, they're just called differently depending on what they cool.

See page 67 in the service and maintenance guide.

About the Fan noise issue:

You can resolve the issue by Upgrading the System BIOS firmware and Lights-Out 100 Remote Management firmware.
