Thanks, I will try some more to get the noise to go away when I get home from work. I havent done any rocking like a baby lol, just gently tipped it in different angles to see if the sound changes, it gets much worse and seems like it even stutters, and the opposite on it's back, runs seemingly perfect. So yeah I'll try some more when I can. The hoses come out the sides of the radiator and pump, it is mounted on the roof of the case arcing in an L shape down to the pump. It is a H100i Platinum SE, I can perhaps get some information off the sticker on the radiator too if I end up taking the radiator off again. Thanks for your advice, I shall let you know how it goes :)

Hi, I am fairly new to building PCs and very new to water cooling, I recently finished a build however when I turn the system on, the water pump is making a constant gurgling as if it has trapped air, when I tip the system horizontally the noise goes away to near dead silence, when I return it vertically it gurgles again. I have ran the system for about 5-6h and it hasn't cleared itself I have taken the whole AIO out and shaken it, had the hoses straight, still the same. Can I get some help please
