Bubbles trapped in AIO pump

[AEGOG]

Hello, I've had this AIO cooler since i first built my current rig almost a year ago now ( Bought it on ebay ). At first it did not have any problems, but after a few months it suddenly started making rattling noise coming from the pump.

 

I did some research on it and found out that it Was bubbles trapped inside the pump itself that were making this noise. The radiator has always been the highest point of the AIO but the bubbles were still trapped in the pump.

 

Today i bought a new PC case and this time i mounted the Radiator on the top of THe case ( Last time it could not fit on the top so i had it on the front of the case ) and thought that would fix the noise, But it did not. I've tried tilting the pc sideways to help the bubbles out of the pump, it works for a few minutes but the problem still remains. I've also tried disassembling the radiator and rotating it around to help it move bubbles, but that did not Work either.

 

The AIO itself is working perfectly i'd say. Pretty low temps on my i5 10600K, but the noise is killing me.

 

Is there anything else I can try, or should i just buy a new AIO?

This is the position it was before

I would chuck it and buy a new one. 

 

If you bought it on ebay used then it's not worth the risk.

Doesn't sound like bubbles.  Sounds more like the bearings have taken a dump.  There is a way to remove air/gas that could be trapped in the system but it requires opening the hose at the highest point and letting the air/gas escape while the system is running.  You can work on the fluid system in your computer just like you can work the radiator system in your automobile.  To remove bubbles/air trapped inside the hoses/radiator in your car, remove the radiator cap before starting the automobile and let the car run for a bit while the fluid is circulated thru the system.  The pump will move the bubbles/fluid thru the system until the bubble reach the highest point and that point is where the radiator cap has been removed allowing the bubbles to escape.  The same process can be applied to the system in your computer.  It just takes a little more effort because the computer system does not have a radiator cap so one must be installed first.

"Bought it on EBay" is all I needed to know... yes, replace it ASAP. Meantime regularly backup your data.
