Strange whining sound from my RX-8

Hello guys!

Troubleshooting question:
There is a high pitch whining sound after the engine warms up. It's not there on startup with cold engine.. I have tried to take the alternator and A/C compressor belts off and the sound is still there. So, what else might create this? It seems coming somewhere behind the alternator. One thing which comes to my mind and haven't tried yet is air leakage somewhere. Any other ideas?

Check the sound out here:

Any help on this problem would be greatly appreciated!

BR,

Do you have any mods?

My water pump made some pretty bad noises when it's bearing was going out.
