Fan Control - SUPERMICRO A2SDi-8C-HLN4F?

[ObiTobi]

Hello,

I need your help because I don't really know how to set this up. Searching the net didn't yield any useful results either.
I have the following problem:
Everything runs normally and there are no problems. Now in winter, when I open the window where my NAS is located, it is cold in the room. And then the following alarms constantly appear.

Code:

New alerts:
* Fan FAN2 Deasserted Lower Non-recoverable going low : Reading 1200 < Threshold 200 RPM.
* Fan FAN2 Deasserted Lower Critical going low : Reading 1200 < Threshold 400 RPM.
* Fan FANA Deasserted Lower Critical going low : Reading 1900 < Threshold 500 RPM.
* Fan FAN2 Asserted Lower Critical going low : Reading 0 < Threshold 400 RPM.
* Fan FAN2 Asserted Lower Non-recoverable going low : Reading 0 < Threshold 200 RPM.
* Fan FANA Asserted Lower Critical going low : Reading 500 < Threshold 500 RPM.
* Fan FAN3 Asserted Lower Critical going low : Reading 400 < Threshold 400 RPM.
* Fan FAN3 Deasserted Lower Critical going low : Reading 1400 < Threshold 400 RPM.
* Fan FAN2 Deasserted Lower Non-recoverable going low : Reading 1200 < Threshold 200 RPM.

It's clear that you don't need to turn the 3 fans up so high because everything gets colder, but the alarms are annoying.
I found the following command on the net (I think it even comes from the forum here). It doesn't seem to work somehow or I'm implementing it incorrectly.

Code:

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32

I have 3 fans connected to FAN2, FAN3 and FANA.

Code:

mynas001# ipmitool sensor | grep -E "^FAN|^CPU Temp"
CPU Temp         | 51.000     | degrees C  | ok    | 0.000     | 0.000     | 0.000     | 88.000    | 93.000    | 93.000

FANA             | 1900.000   | RPM        | nc    | 300.000   | 500.000   | 700.000   | 1900.000  | 2000.000  | 2100.000

I am very grateful for any tips.

This worked for me. Adjust as-needed.

I had to play around with the thresholds a bit until the errors would stop.

ipmitool -H <yourmanagementIP> -U ADMIN -P <yourmgmtpassword> sensor thresh FAN3 lower 50 100 150
