This is strange. The lack of alarms for Fan2, Fan3 and Fan4 can be
easily explained by the min being set to 0. But for CPU_Fan you should
get one.

Are you able to get _any_ other alarm flag to raise?

Which version of lm-sensors are you running?

Can you please locate your chip under /sys/class/hwmon and list the
name and contents of all the "*alarm*" files there? This will tell us
whether this is a hardware/driver issue or an lm-sensors (user-space)
issue.
