[SOLVED] Water pump making a sizzling/crackling sound

[northx]

I moved my case around to take out an HDD which required the pc to be on its side. After finishing and booting up I heard a nasty sizzling/crackling sound coming from my aio water pump. I assume it’s air bubbles. Is this normal and will it go away on its own? The pump has been completely quiet before I did this. It’s a Corsair h100i Pro.

I would assume it's air bubbles as well.
I have something similar happen....and yes....they did go away.
...but perhaps there is a way you can purge the air so you don't have to wait? I'm not familiar with that setup....but perhaps there is some sort of an air bleed?

Have the similar setup, and it is an issue with their particular coolers. Mine did this when i first booted it for about a day or so, just air bubbles in the pump.
