Awful loud rattling sound from CoolerMaster liquid lite pro

I have had my pc from PCS for almost 12 months now, the AIO started making a very loud rattling sound, directly on the block over the CPU.

I have tried looking for troubleshooting online and did find some useful tips, the sound completely disappears after I sit it on its side or almost upside down, but the sound comes back after about 2 minutes.

HELP!

Kind Regards

Can you post your full specs?


It sounds like it might be a failure of the AIO pump, which does happen occasionally.

Yes sure, spec below.

Processor (CPU)
AMD Ryzen 5 5600X Six Core CPU (3.7GHz-4.6GHz/35MB CACHE/AM4)
Motherboard
ASUS® STRIX B550-F GAMING (DDR4, USB 3.2, 6Gb/s) - ARGB Ready!
Memory (RAM)
16GB Corsair VENGEANCE RGB PRO DDR4 3200MHz (2 x 8GB)
Graphics Card

1st M.2 SSD Drive
1TB INTEL® 665p M.2 NVMe PCIe SSD (up to 2000MB/sR | 1925MB/sW)

As my PC is running idle I've checked the CPU temperate and it is 30c consistently, the sound disappears if I turn it upside down or try and gently tip it side to side, it sounds perfect for 1-2 minutes and then back to a loud clicking sound

Thanks!

And under load? (Run something like Prime95 to put your CPU under 100% use.)

Could you post a photo (or ideally a video with the noise in question) of the inside of your system? In particular, it would be good to see how the radiator is mounted and how the tubes connecting it to the CPU plate are configured.
