Can't control fans after upgrading to Fedora 33 x64 kernel 5.8.14

Hi there,
I've recently upgraded from kernel 5.4.70 to kernel 5.8.14, but there's a problem: I can no longer control the fan speed on my Asus VivoBook Pro N552VX.
Unfortunately, I can't roll back to the old kernel as I upgraded from Fedora 32 to Fedora 33, so I'm stuck with kernel 5.8.14.

This is the output of sensors-detect: https://pastebin.com/HvKi18Pi

and this is the list of sensors:

Code:
[FranceBB@router-localhost ~]$ sensors
iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:            N/A  

asus-isa-0000
Adapter: ISA adapter
CPU Fan:        2400 RPM
NVIDIA GTX950M:  +58.0C  

nouveau-pci-0100
Adapter: PCI adapter
NVIDIA GTX950M: 900.00 mV (min =  +0.60 V, max =  +1.20 V)

BAT0-acpi-0
Adapter: ACPI interface
Battery Voltage:  14.40 V  

pch_skylake-virtual-0
Adapter: Virtual device
Platform Controller Hub:  +54.0C  

nvme-pci-0500
Adapter: PCI adapter
Intel SSD NVME:  +34.9C  (low  =  -0.1C, high = +76.8C)
                          (crit = +79.8C)

acpitz-acpi-0
Adapter: ACPI interface
Motherboard:  +58.0C  (crit = +103.0C)
And we can clearly see the speed of the CPU fan, however, when I try to run pwmconfig I get:

Code:
[FranceBB@router-localhost ~]$ sudo pwmconfig
[sudo] password for FranceBB: 
# pwmconfig version 3.6.0
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

Why is that?

For those that wanted to know how I solved the issue, by opening Nautilus as root (sudo nautilus) and navigating to /sys/devices/platform/asus-nb-wmi/hwmon/hwmon6 I was able to modify the file called "pwm1_enable" and set it from 2 to 0 and it worked with the Fan now spinning at maximum speed.
