Just concluding this thread. So spoke with Corsair Support and they suggested the noise was indeed indicative of premature pump failure vs. air. I RMA'd the AIO, received and installed a new one tonight and its whisper quiet. So lesson for anyone else who may stumble upon this thread with the same issue - the noise in the video is not what air sounds like - its a faulty/damaged pump!

Thanks c-attack for the help. The noise is actually very consistent - suspecting its a bad pump. Opened a ticket. Will keep this thread posted on the end result - just in case someone else stumbles upon this with a similar issue in the future!

lol yes ive seen the infamous gamer nexus video. My rad is front mounted, with the rad significantly higher than the pump. It is not a mounting issue.

Thanks c-attack. So i bend the tubes as advised, and rotated my case pretty much 80 degrees back, so the tubes were straight up. Ran it in extreme for 10min, and tried cycling between extreme/quiet for a few minutes. Still no resolution to the noise. Starting to think it must be a pump issue as i cant imagine how any air would still be trapped in there after that exercise. Any additional thoughts?

Hi Corsair community, I recently purchased and installed a h150i elite capellix in my new build. All was working great for about a week, and then all of a sudden i am hearing this loud noise in quiet mode. The noise is less audible in extreme mode. Thinking this may be an air bubble, i have tried cycling between quiet and extreme at 10sec intervals, i have tried tilting the case back and fourth while in extreme mode, and no luck whatsoever. Is this indeed air, or is it a pump malfunction? Here is a link where you can hear the noise:

Thanks c-attack, this is an excellently informative answer. This is exactly the type of info I was looking for and youve helped me settle on a decision Ive been debating for a long time! Based on your explanation, I think Ill go ahead with the 4000x (i prefer a smaller form factor), with an H150i front mounted and 3 exhaust fans (1 rear, 2 top). Sounds like that should work well. Thanks a million!

Thanks c-attack. I guess my next question would be then, if i go H150i mounted in the front as intake, and two top 120's and a rear 120 as exhaust, how would the thermals be? Im worried about blowing the hot air from the radiator into the case, and also worried about the airflow in general through the rad with the glass front of the 4000x. Am i in general just better off going 5000x with 360mm rad top mounted, 6 intakes in front and side and 1 rear exhaust? Im not a fan of the 5000x due to the enormous size, but i guess if thats my best option?

bumping this, as still trying to figure out if i can top mount an H115i Capellix with a Dark Hero VIII, Trident Z Neo, or will RAM clearance be an issue? Im pretty sure the DIMMs on the Dark Hero VIII are lower than standard, no?

Hey Hivemind, Need some advice; I'm working on a new build. Specs as follows: Chassis: 4000x CPU: Ryzen 5950x Mobo: ROG Crosshair VIII Dark Hero Ram: 32 Gb Trident Z Neo CPU Cooler: Ideally I would love to top mount the H115i Plat or similar 280mm AIO The Question: I know the RAM slots are a bit lower on the VIII Dark Hero. Does anyone know if Ill have enough clearance in this case to get a 280 mm AIO top mounted? 240 mm wont cut it for this CPU, and i dont want to front mount the AIO, as the case already has pretty poor airflow, and that will make it even worse. Any suggestions are greatly appreciated!
