when I move the cursor, motherboard making little buzzing noise?

[Miticm]

It happens in hackintosh environment but no such noise when running windows. It only happens when I move the mouse around, the noise is not noticeable but when it is quite and I put my ear close to the motherboard I can hear it. Can someone help or does anyone has the same problem?
my motherboard is Asus maximus vii hero, cpu is i7 4790k , cpu is msi 980 ti, running sierra 10.12.5
