AIO crackling noise

[zasker55]

Hey,

I put my new rig together on Monday using a Coller Master ML240 AIO, it's doing the job fine however, the AIO now has a 'crackling'. I've had a look on google and it would seem to be air bubbles, a few videos suggest shaking it and that the noise should lessen after being on for a while but I'm curious is there a way to bleed it or any other ways to stop this as neither has helped.

Yup... But is there any suggestions for getting this noise to stop? 

It's not exactly a soothing sound.

if you havent had it for long you could return it if not then you could shake it vigorously till the air is purged to the top

Nope, you can't bleed an AIO (unless if its a particular unit with a fill port). Just shaking the hell out of it to move the bubbles in the pump to the rad is the way to go. Ideally have the radiator higher than the pump so it'll have reason to stay there.

I take it from what you're saying that the air is trapped in the pump itself? - So, I've tried elevating the front of the case so the radiator is higher still, which has actually decreased the noise, so given a few hours it may remedy the problem (hopefully). If not I'll shake it I assume shaking it I need to take the AIO out of the rig, or can I just shake the rig?

If you don't have any mechanical drives, I would say its okay to shake your rig. Otherwise unmount the AIO and the shake the pump part of it alone. Or as you say, you can wait to see if they would naturally dislodge.

So far the noise has pretty much stopped, whilst it's been tilted. Rather than tempting fate, I'm going to leave it alone now and see how it is in the morning. Hopefully, I don't need to shake it.

Update... 

I tried rotating the rad so the pipes were at the bottom, however, this didn't work. I've took the unit out of the rig and gave it a good shake and it seems to be working a-ok.
