rx1620 server fan are very noisy? Any workaround?

[TY 007]

Hi,

rx1620 server fans are very noisy. Would like to convert it as noiseless-friendly as rx2620.

Any workaround? Assume rx1620 server is only powered-on in a Air-Conditioned Room. Take out the Cover? Take ALL the server fans?

Thanks

hi ty007, have you tried replacing the fans already?

Tried before, no luck :(

This Server is designed to be placed at the data center.

I would recommend you upgrade your office friendly RX2620

refer to this link:

How to convert rx1620 to non-data center, noiseless-friendly version? For example, rx2620?

I am thinking to modify the rx1620 Server Fans using PC-Based Fans.

At the same time, the rx1620 Server able to boot-up the OS.

For example - DC Fan:

there are 3 fans in a rx1620, i.e. cpu fan, memory fan and power supply fan.

there is a isensor command at the efi prompt where you can check the fan status e.g.

fs0:\MISC> isensor read

11 Fan 1 (PSU) = 01 --- 0001 (00) transition to OK
12 Fan 2 (Mem) = 01 --- 0001 (00) transition to OK
13 Fan 3 (CPU) = 01 --- 0001 (00) transition to OK

...

E0 Fan 1L Tach = 69 ES- 00C0 12600.00 RPM
E1 Fan 1R Tach = 68 ES- 00C0 12480.00 RPM
E2 Fan 2L Tach = 5F ES- 00C0 11400.00 RPM
E3 Fan 2R Tach = 65 ES- 00C0 12120.00 RPM
E4 Fan 3L Tach = 67 ES- 00C0 12360.00 RPM
E5 Fan 3R Tach = 6F ES- 00C0 13320.00 RPM
E8 Fan 1L Health = 00 ES- 0001 (00) performance met
E9 Fan 1R Health = 00 ES- 0001 (00) performance met
EA Fan 2L Health = 00 ES- 0001 (00) performance met
EB Fan 2R Health = 00 ES- 0001 (00) performance met
EC Fan 3L Health = 00 ES- 0001 (00) performance met
ED Fan 3R Health = 00 ES- 0001 (00) performance met


if all the fans appeared ok, there is nothing wrong with the server. the design of this server is such that it is supposed to be rack mounted and placed in a computer room rather than an office equipment.

changing the fan yourself with a less noisier one will not be a supported configuration by hp.

i think this is not support issue. this is more like a sales issue to me whereby you shld contact the local sales who proposed this unit to you to follow up on the matter.

Confirm via isensor the fans are OK.

I know modifying rx1620 Server Fans is not a HP Supported Configuration.

Anyone know how to convert rx1620 Server Fans using PC-Based Fans?

there is a similar technical document in itrc for isensor command :

In fact most servers are designed for data centers where noise is not aproblem.

To be honest, I cannot say how noisy this box is. Between all other servers you cannot hear it.

For office use there are special "office friendly" models of rx2600 and rx2620.

The problem is, the server will track the number and speed of the fans. Any change in the wrong directing and the server will go off to prevent an overtemp damage.
