Corsair H75 air bubbles?

[phate101101]

just built a new system and I'm hearing what I think are air bubbles in the H75 (with 4690K), sounds like water trickling like a leaky tap (can't find any leaks!)

Should I be worried?
Anything I can do to remove the bubbles?

I had a H50 previously and never experienced this :/

*just to note if it matters I'm using a silverstone raven rv02 case so the cooler is at a 90 degree angle, could that cause issues?

@Mod I guess I should have posted this in the watercooling section, can it be moved please?

How long has it been running? I've found it can take a couple of days to fully settle down.

Only about an hour, I was thinking that too though still a bit unsettling (pardon the pun!)

I have a H75 too. After about 5 hours mine stoped the trickling sound. It now only occasionaly does it at startup for about 3 seconds
