If you throttle your CPU, it will not generate as much heat:

You mean permanently or when I'm not using the computer?
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.
Some motherboards have temperature sensors
The GPU seems to be always 41C while the CPU shows a cycle of
some 34-47C.
fan connectors (e.g. 4-pin)
Fan connectors are 3-pin!
The motherboard is Asus ROG Strix B450-F Gaming.
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.
Fans are:
fan front low be quiet! Shadow Wings 2 140 mm
front high be quiet! Shadow Wings 2 140 mm
CPU cooling tower be quiet! Pure Wings 2 120 mm (2)
rear Corsair 120 mm
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:

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.
firmware settings
Where are these? The BIOS/UEFI?
See section 3.2 "BIOS setup program" of the user's manual.
