The SSD thing, I posted here months ago that when I changed from a HD
to SSD, I was surprised that there is still a faint kind of metallic
tinkling sound coming from the area of the CPU heat sink when the SSD
is doing heavy work. I can't explain it, but it's there. Somehow all
those electron running around manage to generate noise.

I think I remember that discussion. I'm betting it's just thermal
expansion as the CPU heats up under load. All those metal fins expand as
they heat up and can make noise as they move through the brackets or
whatever that hold the fins together.

It's similar to the tinking sound that comes from electric baseboard
heaters when they heat up, except the CPU can heat up a lot quicker.


Maybe, but the radiator thing only lasts for a few mins, while it's
changing temps, then it stops. This seems to continue.



You could probably fix it by installing a different heat sink that has
better cooling.

No reason to fix it, you woudln't even notice it unless you went looking
for it. And it only happens with heavy SSD activity, which is rare here.
It might happen with other heavy data movement, or CPU activity, but
the SSD activity is the only place I noticed it.

You could take the SSD out of the case if your cable is long enough.
Easy enough to isolate the sound.
