I've built a PC for the first time. Before I had an iMac. I've noticed my new built is much louder than my iMac. It's loud all the time even when just surfing the web. Any ideas of how and if it's possible to regulate the noise of the fans on Ubuntu 19.04.
I've counted 5 fans:
1 Case Fan, 1 CPU Fan, 2 Fans part of the Graphic Card, and finally 1 fan part of the power supply.
My PC specs: AMD Ryzen 5 2600 Six-Core Processor, Gigabyte Radeon RX580 Gaming 8GB GDDR5, Motherboard B450M MORTAR (MS-7B89), Corsair Vengeance 2x8GB DDR4 2666MHz, Power Supply Corsair CX550M, Case Cooler Master MASTERBOX MB600L.
sudo sensors-detect
This is only part of the Output:
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? AMD Family 17h thermal sensors... Success! (driver `k10temp') Some Super I/O chips contain embedded sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): YES Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes Found unknown chip with ID 0xd451 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 Using driver `i2c-piix4' for device 0000:00:14.0: AMD KERNCZ SMBus Driver `k10temp' (autoloaded): `Chip `AMD Family 17h thermal sensors' (confidence: 9) No modules to load, skipping modules configuration. Unloading cpuid... OK

The output after doing sudo pwmconfig
sudo pwmconfig
# pwmconfig revision $Revision$ ($Date$)
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.
Found the following devices:
hwmon0 is amdgpu
hwmon1 is nct6797
hwmon2 is k10temp
Found the following PWM controls:
hwmon0/pwm1 current value: 81
hwmon0/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm1 current value: 255
hwmon1/pwm2 current value: 33
hwmon1/pwm2 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm3 current value: 122
hwmon1/pwm3 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm4 current value: 122
hwmon1/pwm4 is currently setup for automatic speed control.

it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm5 current value: 122

Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon0/fan1_input current speed: 733 RPM
hwmon1/fan1_input current speed: 0 ... skipping!
hwmon1/fan2_input current speed: 788 RPM
hwmon1/fan3_input current speed: 625 RPM
hwmon1/fan4_input current speed: 0 ... skipping!
hwmon1/fan5_input current speed: 0 ... skipping!
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!
Hit return to continue:
Testing pwm control hwmon1/pwm1 ...
hwmon0/fan1_input ... speed was 733 now 732
no correlation
hwmon1/fan2_input ... speed was 788 now 795
no correlation
hwmon1/fan3_input ... speed was 625 now 623
no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon1/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)? n
Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? y
What should be the path to your fancontrol config file (/etc/fancontrol)?
Loading configuration from /etc/fancontrol ...

sensors-detectand note what it detects for each section, particularly the Super I/O section. You may be able to gain access to control the fans connected to the MB viafancontrol. – rtaft Jun 05 '19 at 12:58
