AIO water pump makes bubbly sounds

I have an Eisbaer LT OCOOL (I think is what it is called) 360mm AIO and today I cleaned by PC out. This involved turning and rotating my PC a lot etc. I put fresh thermal paste on so I disconnected the AIO pump from the AIO pump header on my motherboard, put fresh paste on and then reconnected the pump and mounted the block onto the CPU nice and tight.

Now it is making bubbly noises from the pump and is "idling" on the desktop writing this at 51c (5800X3D). The bubbling noise is a lot quieter but is still there. I am pretty sure my PC was a lot cooler than this before.

Have I damaged the pump? Does it just need to settle?

What position is the radiator mounted ?

Would slowly move the case around so any air can move to the radiator , I believe you can refill/top up that model.

So hot that. I'm idle 26c on my 5800X3D, which the CPU package on my corsair h100i LCD reports. I've had no heating on and windows open, but still even in summer never seen it above 34 - 35c Idle.

It's mounted at the top. Yes it looks like it has a pipe connection that can be undone by the user. Do I need to bleed it?

probably an air bubble inside the pump, running the pump at 100% for a few minutes should sort it out

Not really you would need to replace the air with fluid , just try to move the air upto the radiator for know and then you tinker whenever.
