Ticking noise from AIO pump?

Hi, After about two month of purchasing a Kraken AIO its started to make a consistent "ticking" noise, when I lay my PC on its side it stops until I put it right side up again, I have a video of the noise below, any help or suggestions would be great. Hoping the noise is noticeable on the video.

 
I had one of the original krakens about 5 years ago, that went back with a rattley pump. Make sure the fan/pump header its plugged into is set to 100% in bios, if not run it at 100 for a while and if the problem persists send it back.
 
I think there might be air in the loop.

I had a Slient Loop which is made by Asustek (they make many AIO coolers - probably made yours as well), which made the same noise. It stopped making the noise after a couple of years. A couple more years later, when rebooting my PC, it would thermal throttle my CPU (down of the MHz), but the temp would still climb till 100C and shut down. The only way to fix, was to go into bios and shake my PC a little, till the temp started dropping. Eventually, that didn't even work, so I got a new cooler (a Noctua tower cooler). Its been fine since.
 
To me it sounds like air trapped in the impeller. Stop all the fans, one by one to see if its not them. Try to move your radiator completely above the pump so the air has a chance to go there(while the AIO is on). If it works, consider mounting the radiator in the top position permanently, if you can't, try to mount it where it is now, but with the tubing at the bottom of the radiator, so the air gathers on top.
 
That sound is like what air bubbles could sound.
But what I can gather from video's limited view, unless you have one of the few rotated insides cases, block/pump would appear to be below radiator.
And in that situation air should gather in radiator rising the odds for pump having real issue.
