Fan control on S1200BTL using linux (opensuse)

Hi, I have a xeon server board with 32GB ECC memory as workstation… and I'm annoyed about the loud fan…

# ipmitool sensor | grep -I Fan

 

Sys Fan 2 | 686.000 | RPM | ok | na | 294.000 | 392.000 | na | na | na

 

Processor Fan | 0.000 | RPM | cr | na | 0.000 | 0.000 | na | na | na

 

System Fan 4 | 1078.000 | RPM | ok | na | 294.000 | 392.000 | na | na | na

 

Sys Fan 1 | 0.000 | RPM | cr | na | 0.000 | 0.000 | na | na | na

 

Sys Fan 3 | 588.000 | RPM | ok | na | 294.000 | 392.000 | na | na | na

 

I already disconnect "Processor Fan" but I don't want to disable "System Fan 4"

I have done some study and I think I can control Fan speed with the "ipmitool raw…" command… like I read

Question can you give me the IPMI raw commands to control all the fan's on S1200BTL

thank you :-)

Hello aotto1968,

 

 

Thanks for joining the community.

 

 

First of all to answer your question the fans cannot be controller through IPMI. Fans are controlled by the BMC depending on the cooling requirements. There is a setting that can be changed on BIOS > System Acoustic and Performance Configuration that allow you to somehow manually set up a fan profile depending on your needs.

 

 

About disconnecting any of the fans what will trigger the remaining ones to rev up as a safety measure so definitely is not recommended.

 

 

About the OS just to let you know that doesn't show up within the supported OS for this board: https://www.intel.com/content/www/us/en/support/articles/000006987/server-products.html https://www.intel.com/content/www/us/en/support/articles/000006987/server-products.html

 

 

After that let me forward you a document that would help you to troubleshoot fan issues:

Hope this helps.

Hi

Ive not looked at the Intel hardware itself in depth, however i can tell you with regards Lenovo (which are Intel CPU and Intel chipsets) the fans are only controlled by the BMC and this will depends on the cooling curve you select AND whats installed.

For example in the Lenovo if there is a RAID card then the fans nearest the RAID card are set to be more aggressive, so as more data is pulled those 2 fans would rev up way faster than if a RAID card was not installed. The S1200 has a cooling curve, i always set them to maximum performance and the current server (S1200 series) is almost silent, i get more noise from the PSU fans than the system ones.

To answer your question, ive never been able to control Intel fans via software, especially when its a server, it will be from the BMC which as far as i know means you can only read the data from the fan, not control it.

SYS FAN 4 being 1000RPM will be the one making the noise, i would need to know the if you only have the board or the complete server chassis, also what CPU and RAM are installed to confirm anything (which take me a few days though).

Thank you for the information…

→ I understand that opensuse is a non-supported-os… because I understand that Intel can not support all new OSs for an old board…

→ I doing heat control. my opensuse KDE desktop has a "plugin" for such a task…

and my average temperature is about 30-40°( …

→my BIOS has thermal settings… with the ONLY setting of "High about Sea-Level"

but I understand that the Intel-Borad is NOT designed to manipulate the fan-speed in detail… like a consumer-board does…

Hello aotto1968,

 

 

Not sure how safe it is to control the fan speed via software, probably I wouldn't recommend it myself.

 

 

The next step that I could suggest would be to update BIOS to the latest available and make sure you complete all the requested info at the end of the update:

Let me know how it goes or if you have already done it
