Question a faint but noticeable whizzing sound from new build

[PLSHELPMYDYINGCPU]

Problem: There is a faint whizzing noise coming from my PC but it is not clear as to when or why it occurs. For example, I was on my PC for about 5 hours today before I heard it. It occurred periodically for an hour or so and then stopped again. I've noticed it every night since the pc was built about a week ago. It definitely does not sound normal.

Here is the audio of the sound. It is kind of faint but you can hear it. It starts after a few seconds, you will immediately hear the PC fans and then after a few seconds you will notice the faint whizzing.

Really need advice on this badly so I know if or what I need to return before it's too late.

Place your PC onto the desk or table, remove the side cover and start it.

Initially, see if you can locate the sound that way. If not, GENTLY use your finger to stop each fan for a moment, or even just slow it down to see if the sound changes. If the cooler (Graphics card?) and case fans are not it, consider the power supply but DO NOT stick anything inside your power supply.

Aside from that there is very little able to make such a noise outside a hard drive, if installed, or a pump.

The issue with checking for the sound is that it happens very randomly. Today it has not occurred a single time and I've been using the PC for several hours, I don't know how to trigger it either :\

In this (hardware) case I would be willing to bet that the noise is your pump. They do make a small noise even when working normally. Of course, having the rad and pump installed in the correct orientation can less it - point being that your pump needs not be the high point of the system for air bubbles to get trapped.

My own system seems to work in correlation with the fish tank to create an odd noise while sitting at a certain spot at my desk. It has to do with the air pump and apparently some harmonic thing.

" that your pump needs not be the high point of the system for air bubbles to get trapped." I've heard of this before but I never understood what it meant. My radiator is top mounted and the pump is just curved from the left to the CPU, what does high pint of the system mean?

You mentioned they make noise regardless, Audio recording sound normal to you? My previous PC had a much smaller corsair water cooler and never made such a noise.

With your radiator top mounted, it will be the high spot for air bubbles.

Take an empty bottle and fill it mostly with water. Put a cap on. Holding it normally the bubble will be at the top, of course. In the case that you install your pump where the air bubble can be inside it instead of in the radiator it can cause it not to prime, not to cool properly, or make more noise if not all those things.

There are some good videos on the proper installation of an AIO on YT and the like.

This is 100% just pump noise from the AIO. You could try setting the pump to "Quiet "mode" in the control software, but aside from that you're kinda out of luck with the Corsair coolers when it comes to changing the pump speed beyond that.
