Use a piece of tubing as a stethoscope to isolate and identify the noise 
source(s).

You will not notice a change in CPU fan temperature or speed profiles as 
a function of the Linux governor setting until the motherboard CPU fan 
speed control is working and you change the CPU load.


Here is a Perl one-liner that should peg one core:

$ perl -e "1 while 1"


Press Ctrl+C to stop it.  Open multiple terminals an invoke the same to 
peg more cores.

Whatever interests you -- chipset, voltage regulators, memory modules, 
etc..  Because the instrument is hand-held, the challenge will be 
measuring the same spot at the same distance and same angle every time.

Changing the Linux CPU governor should affect the CPU frequency profile 
as a function of CPU load.  I use the Xfce panel applet "CPU Frequency 
Monitor" to monitor the CPU frequency and the "CPU Graph" applet to 
monitor loading of each core.

On my Intel desktop and server motherboards, CPU fan speed control only 
works with Intel CPU fans.  Aftermarket fans run at full speed all the 
time.  Try your AMD CPU fan.


Get a 3-pin and/or 4-pin fan speed controller and test the fans:

https://www.amazon.com/Zalman-Fan-Speed-Controller-FANMATE-2/dp/B000292DO0/

https://www.amazon.com/Noctua-NA-FC1-4-pin-PWM-Controller/dp/B072M2HKSN/


While STFW, I found a what might be a replacement for your external fan:

https://www.amazon.com/Wathai-Controller-Receiver-Playstation-Component/dp/B07VYGQPCZ/


The video card and power supply fans should have automatic fan speed 
control.  The video card manufacturer might offer a firmware or software 
utility for tuning the fan speed control profile.  A gamer power supply 
might have such a feature.  That said, I expect the factor defaults 
should be good enough for now.  I would leave them alone, unless you 
definitely hear too much noise coming from one or both.


Small fans at high RPM can be very shrill -- e.g. the spectra has a lot 
of high frequency energy.  I use 3.5" HDD mobile racks with two 30mm 
fans each (StarTech DRW115SAT).  When I install four in a computer, it 
sounds like a B-52!
