[SOLVED] lm_sensors unable to detect pwm fans

I want to set up fancontrol, but pwmconfig could not find anything.
Motherboard: Asus Prime x470-pro

Output of sensors-detect:

# sensors-detect version 3.6.0
# Board: ASUSTeK COMPUTER INC. PRIME X470-PRO
# Kernel: 5.5.8-arch1-1 x86_64
# Processor: AMD Ryzen 5 2600 Six-Core Processor (23/8/2)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): yes

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes

Now follows a summary of the probes I have just done.
Just press ENTER to continue: yes

Driver `to-be-written':
  * ISA bus, address 0x290
    Chip `ITE IT8665E Super IO Sensors' (confidence: 9)

Driver `k10temp' (autoloaded):
  * Chip `AMD Family 17h thermal sensors' (confidence: 9)

Note: there is no driver for ITE IT8665E Super IO Sensors yet.
Check https://hwmon.wiki.kernel.org/device_support_status for updates.

No modules to load, skipping modules configuration.

Unloading i2c-dev... OK
Unloading cpuid... OK

Output of pwmconfig:

# 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/bin/pwmconfig: There are no pwm-capable sensor modules installed

Is this a problem with the motherboard?
On google I see that the driver for the motherboard sensors are `it87` or `nct6775`, but they are no longer maintained. Is there anyway of getting this to work now?

Thanks in advance.

Update:
Apparently even though it's not updated for 2 years, the it87 driver which is available on AUR still work. However, sensors-detect still says it is not supported, even though sensors will report the temperatures.
