Hello guys,
As the title says Im having all new build but keep noticing this sound coming from the PSU. It almost feels like it's scheduled as it comes and goes or pretty even intervals and it doesn't matter if the Pc is idle or running full on.

The noise you can hear comes and goes every 1min or so. https://voca.ro/16RaYDVeuQM7

Any ideas or recommendations?
The PSU is new, no dust or anything.

What PSU is it?
Sounds like a fan noise to me.

If its new, you should be able to return to get a new one.
That's Corsair 850e gold full modular. Just wonder If anything could be done about it since would be a pain to return and wait for new one. Is it dangerous for the rig?
