Hello thanks for choosing Dell.
Is the temperature in the room high(er)?
Do you have anything plugged in the PCI slot?

No there is no problem with temp in the office or rack.

CPU1 Temp is 33 C, system board exhaust temp 31, system board iniet temp 27, max dimm temp 29 (all temp are reading temp from idrac).

There is issue fan speed can be set under 50% and I don`t know why.

Hello,
a server, especially a rack version, is not made to be installed in an office, as it is noisy .
Have you updated iDRAC and BIOS?
I also recommend that you read this information regarding fans

Custom Cooling Fan Options for Dell EMC PowerEdge Servers

No my question is, did you tried to update iDRAC firmware and BIOS? Which version are installed?

If you check this documentation pag 30 you have the server with category 3 acoustically usage.

It depends also about the configuration of the server. Anyway you can see that LpA value is 40 dB.

That can be ok for an noisy office but you can hear it if th office is really quiet.

Dell PowerEdge R350 Technical Guide

This is 15th generation.

I tried idrac via bios too, there is limit 50% too.

I don`t agree with the regard because this server can be use in office too.

This is from technical guide:

Dell EMC PowerEdge R350 is a rack-mount server appropriate for attended data center environment. However, lower acoustical
output is attainable with proper hardware or software configurations. For example, the minimum configuration of R350 is quiet
enough for typical office environment.

and another citaion from this guide.

Table 20. Acoustical performance of R350 acoustical configurations

40dB in idle and 60dB in feature rich...sorry 40dB is noise from your fridge not from your compresor...because 9000rpm is noise like compresor.

Btw server config Xeon E-2314, 16GB RAM, 2xSSD a the only noise is made by system fans.

There is only one issue  stupid setup in 50% limit

I`am going to make upgrade (6.00.30.15 to 6.10.30.20) and we`ll see.

Mate I swear this noise from fans in 50% is really annoying and nobody would want to hear it in noisy or really quiet office;o).

Edit: As I feared no change with newest idrac fw...stil 50% barrier.

Ok I`ve tried to change fan speed via impitool but there is a problem with privileges.

Any hint guys?

PS C:\Program Files\Dell\SysMgt\OM_iDRACTools\IPMI> .\ipmitool -I wmi -H 192.168.1.63 -U root -P calvin raw 0x30 0x30 0x01 0x00

Hello,

you can try setting the user privilege to level 4 which is Admin level and try the command again. 

Unfortunately i didn't found any documentation, only this but it is related to another system

Dell Technologies VEP4600 BMC User Guide | Dell US

Dear Dell experts,

I am having the same problem on IDRAC 6.10.30.20 and the latest BIOS (1.6.3). The problem is that the minimum fan speed can't be set under 50%, and 50% is simply too noisy (65dB) directly near the server.

Your idea to set the privilege level to 4 is not helpful, the root user has already Administrator rights...

Please check your firmwares and publish a BIOS/IDRAC version where it is possible to set the minimum to 20% or something else where the noise level is not as loud as a mower in 10m distance, I don't understand why the server has to be this noisy, if the inlet temperature is low enough... 

Kind regards,
Manuel

Hello thanks for choosing Dell. But I'm afraid there's nothing we can do basically at this point: you have updated your firmware, And 15G, the IPMI privilege has been revoked as well. We could wait to see what other contributors would think but I also doubt that what else would be avaialble. Sorry I couldn't be of help this time.
