[SOLVED] Noisy pump(?)

[realSRK]

Hi, I've experienced a noise coming from my pc lately but I cannot identify its source. My guess is that it's from the pump, I've already submitted a ticket to NZXT. I've recorded a video of it here:

I have confirmed that the noise isn't a HDD or a fan.
My PC:
I7 9700K
ASUS ROG Z390-F
ASUS RTX 2070 Turbo
NZXT X73 AIO
Corsair Vengeance RGB PRO 8GB x4
Corsair RM850x
NZXT H710 case

Thanks in advance.

Maybe you can do this?

Tried that

How do you have the radiator positioned in the chassis?
Is the pump header set to PWM mode instead of auto?

Hi, my radiator is front mounted and the pump header is set to "DC" in BIOS

Ok.
Is the tubing entering the rad from the bottom, or the top?

The top

Can you give it a 180 if the tubes aren't too short?
The purpose of vertically rotating the rad 180 degrees:
These units are not topped off with fluid, so there is air present. With the new orientation, the pump should push the stray air bubbles/pockets into the rad, after which it'll rise to the other end and get trapped there.

I'll try that and let you know 👍

Unfortunately it didn't seem to work 😅. I ran it like that for a good half an hour. The radiator is too big for me to put it in flipped 180 so I had to hold it there 😅.

Case closed, it was a fan after all.
I first suspected a fan because it seemed to have a lubricant leak, I changed it, yet it still made the noise so I assumed it was something with the pump. Then I curiously checked the fans again and, to my surprise I changed the wrong fan.
Sorry for wasting your time 😅👍

The problem part was found within a short period of time, as well as being easily replaceable, so it's all good.

Set the pump header for PWM. Nzxt uses a variable speed pump, it slows down if it's not needed. Prolongs the pump life and runs quieter. Cam will adjust the pump speeds automatically.
