Yes, the fan speed can be modified by SAS expander console commands to setup temperature threshold value.
There is a temperature threshold setting by the expander console port, you can try to set up a higher level on T1 temperature which will get a lower fan speed.
- Expander JBODsâ€™ fans speed are controlled by temperature threshold.
- Four temperature settings in Celsius are T1, T2, warning threshold, and alarm (critical) threshold.
How to configure temperature sensor
Four temperature settings in Celsius are T1, T2, warning threshold, and alarm (critical) threshold.
(A) Get the current temperature settings
Temperature in Celsius (t1=20 C, t2=55 C, warning=50 C, alarm=55 C)
(B) Set temperature with new T1=30 C, T2=52 C, warning threshold=48 C, and alarm threshold=54 C. The
new setting will take effect after reset.
