How to monitor CPU FAN RPM?

[YKorc]

I run CPU-Z stress test and coretemp utility to monitor CPU temperature

I observe that the CPU 2 has higher temperature than CPU1

The difference is about 15 celcius

Visually, seems that CPU_FAN_2 rotates slower than CPU_FAN_1

But I need to confirm it by viewing some utility.

The issue is that SpeedFAN utility doesn't detect any FAN in the system

Intel Extreme Tuning Utility doesn't display FAN RPM.

Is there another way to monitor CPU FANs?

Hello Yaroslav-Korchevsky,

Thank you for joining the community.First of all I would like to ask you what server board model are you using.There are a couple tools you can use to monitor the fans RPMs. First one is the server board management controller (BMC) console. The BMC is the main management tool that will allow you to monitor most of the aspect of the server functionality plus remote KVM. For detailed usage check the following document: https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/Purley_RMM4_BMC_User_Guide.pdf https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/Purley_RMM4_BMC_User_Guide.pdfSecond tool is the Active System Console that you can download for your particular server board under the https://downloadcenter.intel.com/download/26917/Intel-Active-System-Console-for-Intel-Server-Boards-and-Systems-based-on-Intel-62X-Chipset downloadcenter.intel.com . For detailed usage please go to the following URL and select the one that matches your ASC version for your server board.Just to warn you that none of these tools provide a real time monitoring and there is a refreshing time of about some seconds between readings.Hope this helpsJose A.
