I got the PC back from PC today (my previous thread: https://forums.overclockers.co.uk/threads/gpu-water-block-leaked-again.18768555 ) I noticed that the water reservoir was loose and seemed to be dripping liquid. So I tightened it back up and the dripping stopped. Now I've noticed some bubbles in the system. I can see the bubbles in the tubes and also some smaller bubbles in the reservoir that float to the top. Will the bubbles work their way out or do I need to do something? I'm a novice when it comes to water cooling loops. Thanks for any advice guys.
