I have been hearing a sound coming out of the Cooler Master 500W Bronze power supply in my new desktop pc, HP Omen 30L.
I hear the sound most times when I'm actively using the PC, like scrolling through a webpage, open a new folder, click on start menu.
Then I found out that the fan inside the psu spins and stops repeatedly for half a second causing that sound. Like I mentioned, it happens whenever I do almost anything.
Is there a way I can make it stop spinning like this? Or perhaps keep it on all the time?
I would appreciate any suggestions you can provide.

I remember that the bios was updated at some point on day 1. Could the issue be due to that? I tried to rollback from F.02 to F.01 buy it failed because it was "unable to open bios signature file."
I tried to download older bios file but it's not available on HP website. The only one I see is version "F.02 Rev.A" for HP Consumer Desktop PC BIOS Update (ROM Family SSID 8876).
