could be belt squeal ? Tensioner bearing ? compressor bearing squeal ? Alternator bearing , water pump …….I don't like doing this but try wd40 at each location to pinpoint it ! when it goes away you found it .

as for the high rpm ,possible tach is not reading correctly . theres a way to check ,if I remember correctly : you hold the ac fan buttons down(up/down) at the same time until the display reads 0 , then press the fan button in the middle till it shows 6 . then it will show you a number , multiply it times 25 and that's the correct rpm .
