Hello,
I'm having a very strange problem with this module... sometimes the fans are recognized in sensors and /sys/class/hwmon/hwmonX but sometimes they aren't. NBFC reliably works with this laptop for reference.
Here's the dmesg log (I manually unloaded and reloaded it multiple times)

^ yay, they now show up in sensors!
asus-wmi is not loaded. Even when it's loaded the same behaviour applies.
Here's my current kernel config since I'm on Gentoo
