Subject: file name changes between reboots : /sys/class/hwmon/hwmon[0->1]/temp1_input

I'm wondering where to blame a nagging issue with these file names :

t44 ~ # ls -l /sys/class/hwmon/hwmon?/temp?_input
-r--r--r-- 1 root root 4096 Jan 30 13:57 /sys/class/hwmon/hwmon1/temp1_input
-r--r--r-- 1 root root 4096 Jan 30 13:57 /sys/class/hwmon/hwmon2/temp1_input
-r--r--r-- 1 root root 4096 Jan 30 13:57 /sys/class/hwmon/hwmon2/temp2_input
-r--r--r-- 1 root root 4096 Jan 30 13:57 /sys/class/hwmon/hwmon2/temp3_input

It appears sometimes after a reboot / new minor stable kernel that the first file name is found in hwmon0 instead of hwmon1.
That's prevents me from adding that sensor file to the thinkfan.conf file b/c thinkfan refuses to start then.

This is a Lenove T440s with a a64 bit Gentoo Linux and 3.18.X-hardened kernel.
