No cables are anywhere near fans, and none are touching vibrating parts. The sound accours even without overclocking.
When booting, as soon as the screen goes black just before the desktop comes up. It starts. Just as loud as the noise from the fans.

i have a big cooler on the CPU, so i can't get my ear close enough to the board to pinpoint the source 100% But it has the be around the CPU somewhere.
