So whenever my CPU gets under load, it start making a weird noise.
Video with the noise: https://www.youtube.com/watch?v=QKZWtnSRy14

It started after I took the CPU cooler and put it on again. I don't know if the noise is from the CPU or something else, though it definitely sounds like it's coming from the CPU-area.

The CPU is an I7 8700K and the Cooler is the Corsair H60

Does anyone have any idea, what it could be?
 
Solution
I think its interference as magnetic fields in coils (Coil Whine) something is doing you hear that, mostly when you're writing to HDD or doing heavy load.
Its normal.
