Install the Debian package 'cpufrequtils'.


Use cpufreq-info(1) to get information about CPU frequency settings, 
including the governor.  Use cpufreq-set(1) to make changes.


For example, here is my daily driver laptop.  Debian offers two governor 
settings, "powersave" and "performance".  It booted up with the 
"powersave" governor.  If I were playing games, crunching numbers, etc., 
I could change the governor to "performance":

2021-08-22 11:40:22 root@dipsy ~
# cpufreq-info -g
performance powersave

2021-08-22 11:42:37 root@dipsy ~
# cpufreq-info -p
800000 3300000 powersave

2021-08-22 11:42:44 root@dipsy ~
# cpufreq-info -f
825551

2021-08-22 11:44:50 root@dipsy ~
# cpufreq-set -g performance

2021-08-22 11:46:14 root@dipsy ~
# cpufreq-info -p
800000 3300000 performance

2021-08-22 11:46:23 root@dipsy ~
# cpufreq-info -f
2539034


When I'm done, I can change the governor to "powersave":

2021-08-22 11:46:59 root@dipsy ~
# cpufreq-set -g powersave


Some of my other machines offer additional governors -- "powersave" and 
"userspace".  Run "cpufreq-info -g" to see what Debian offers on your 
motherboard.

The user's manual:

https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/ROG_STRIX_B450_F_GAMING/E14401_ROG_STRIX_B450-F_GAMING_UM_WEB.pdf


The table "specifications summary", "Internal I/O Ports" on page xii says:

1 x 4-Pin CPU fan connector
1 x 4-Pin CPU_OPT fan connector
1 x 4-Pin AIO_PUMP connector
3 x 4-Pin Chassis fan connectors


See section 3.2.3 "QFan Control" for how to use the Setup utility to 
control fan speeds.

>         projector extra     fractal Silent Series R3  140 mm


What is "projector extra"?


The "be quiet!" fans appear to be made in 3-pin and 4-pin versions.  We 
need a model number to check the Corsair fan.  The "fractal Silent 
Series R3" appears to have 3 pins:

https://www.fractal-design.com/wp-content/uploads/2019/06/Silent-Series-R3-Fans-Product-Sheet-0.23-MB.pdf


You will want to identify which fan is connected to which motherboard 
connector.  See user's manual section 1.1.2 "Motherboard layout". 
Document connections using the motherboard connector names.


The Setup QFan Control should be able to control the speed of either 
3-pin or 4-pin fans.  I would try "DC Mode" for 3-pin fans and "PWM 
Mode" for 4-pin fans.

See section 3.2 "BIOS setup program" of the user's manual.
