So just to be fair this is NOT a Debian specific issue as I run several distros 
including Debian and Windows10. I have a recently built DIY computer that is 
making a LOUD squealing sound. I thought of fan bearings at first and I tried 
individually stopping each fan to see if the noise stopped one was bad on the 
Enermax 360 cooler so I replaced it. That seemed to get rid of the issue, but 
after about 2 weeks it returned even louder. I checked every fan but none were 
the culprit. I have checked the graphics card fans also and they are fine. This 
only seems to leave the Enermax liquid cooler as a possible issue.

I have been on this list for MANY years and have an idea that someone here may 
have had similar issues. If so, please advise as to your solution, especially 
if the way it is mounted is of concern. Mine is mounted vertically with the 
tubes at the top going to the CPU mounting block. This is on a Ryzen 1950 CPU 
so I must have a high capacity cooler.
Thanks!!

It's not coil whine in the power supply, is it?
