nah... LLC does not fix the issue..
sure, it should not... because those noises are accompanying the change on vcore that happens while cpu is shifting back and forth between lowest multiplier and 20x multiplier...
ie going from being stepped down to full speed and so on..
I've noticed the way EIST works... which I find weird. and don't know if it works with you like this or not..
it seems that under light loads.. the cpu is shifting to full speed, then gets stepped down, then full speed again, then stepped down... etc..
it doesn't keep a constant clock...due to changing multipliers... so that means that vcore is going up and down every second on light loads... and I think that what produces the noise...
of course thats not the case with high loads, which makes the cpu constantly full speed
I concentrated on listening to the noise closely..it pretty much seems like a hdd on activity...a bad hdd which when spins makes a little squeaky whistle
this noise is both annoying and keeping me worried on the same time...
