Forum Post: RE: ADRV9009-ZU11EG RF-SOM expected operating temperature Hello, I did some verifications ... axi_fan_control is built by default when the "build all ADI driver petalinux kernel option" is enabled. I've the fancontrold daemon running as a background process on the target. I monitored /sys/class/hwmon/hwmon3 pwm1 and input_temperature1 at the initial warm-up and I see the pwm1 value to switch as documented in https://wiki.analog.com/resour....ces/fpga/docs/axi_fa . I guess the 75 Deg. of temperature the two adrv9009 chips can be considered as normal and acceptable. Please inform me if this isn't the case. Regards, Joel
