@MeFor3 Not much beyond what I noted above: To rule out a trapped bubble, dismount the cooler and hold it so that the CPU block is the lowest point and the hoses are oritented up toward the rad. Shake it to dislodge any bubbles from the block. Orient the rad so that any bubbles in it will go...

@Paperdoc in the end I went the RMA route. As part of the RMA Deepcool support asked me to destroy the LT720 and send them proof of destruction instead of returning it, so I was able to drain the liquid from the cooler. In the liquid, I found a small flake of plastic. Not a bubble after all...

@Paperdoc Seems it may have been a bubble after all - running from boot on its side and then tilting the computer so that the IO ports to the cooling block were pointing 45 degree upwards while keeping the edge of the radiator above the block and shaking (gently) caused an audible release of...

Your logic is the same as mine at first, but a few things make me question this: 1. The radiator is mounted above the block, so the block is the lowest point in the loop and should be easily able to shed a bubble. 2. Tilting the computer around as no impact on the noise. I would expect at least...

I just built a computer and I have a worrying issue. The PC boots normally and is almost completely silent at first. At some point, usually between 2 and 60 minutes after boot, a very loud buzzing noise starts to happen. Using a stethoscope, I have narrowed it down to the CPU cooler block that...
