Question Cool Master ML240L bubble noises issue

[lavazza]

Hello,

I have been using this Cool Master ML240L for 18 months and since some days it has become very noisy. Noise of little bubbles inside the pump. I don't know why it happened suddenly, the PC has not been open nor moved at all.

If I tilt the tower on a side, the sound stops, than it comes back some minutes later.

If any of you has had that problem and solved it, so I'll be gratefull if you share your experience before I send the product back to the support.

Thank you

it is recommended in your water loop to have radiator as highest point otherwise air bubbles may get trapped in your pump
doesnt really matter if its aio or not
