Belt squealing/screeching past 3200rpm or so

[sloth]

I've had this on both of the KAs that have been in my car, any time I put the engine past 3200rpms or so (2800 or so if it's still kinda cold) I get a loud screeching noise from the engine..but I don't have eyes/ears in two places so I can't tell what belt/whatever this is that might be doing it.. Anyone have any ideas?

Well there's only 3 belts so inspect/tighten all of them.

Mine did the samething, replaced the belts and sound is gone.
