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

I'm guessing assuming you don't have any (as Gene would probably say) spinning 
rust drives?  On a loud squealing sound, that would be my first suspicion (as I 
have spinning rust drives).

I keep a session of gkrellm running on the right edge of the screen, and 
one of the things it does is tell me how hot things are, and its telling 
me the hottest in a 3.7GHZ i5 is physical id 0, at 31C. A 6 core i5 is 
28C for all 6 cores, shown individually. IIRC you can have it turn the 
numbers red if it gets above 75C.

Where is it that you are running to with that birdseed?

Apologies that I have no experience, well, beyond the little "Elf
sneezes" my ASUS exhibits, but it occurred to me to ask if you have a
way to post a sample sound byte that might help someone identify
what's going on...

Just thinking out loud.. :)

PS The "Elf sneezes" turned out to be a last minute warning that the
ASUS was overheating and was about to shut down posthaste, immediately
thereafter, even. :)

Squealing issue in a liquid cooler sounds like you might have an air bubble
someplace you shouldn't?

HTH.
