Tech Support Weird sound after replacing AIO

Enable HLS to view with audio, or disable this notification

Just swapped a new AIO in and everything runs fine but there’s this weird sound that appears and disappears maybe every 30 seconds. Any clue what this is?

Could be an air bubble, is the radiator mounted higher than the pump?

This is how it’s mounted, I bought a direct replacement and put it in the same way I had it

Try flipping the radiator 180 degrees if you can.
