Hello guys!

So I yesterday I finished my water cooling loop and I filled her up and did the leak test and bleeding out the air bubbles. However the system was so loud and there were hundreds of bubbles! I was sure there was a leak somewhere but I couldn't find one.

Finally I decided to add more water in the resivouir and the pump imidiealty quite down and the bubbles nearly went away all together and everything is running fine.

However I am a bit concerned if by letting the pump run with so much air in the loop, if I have potentially shortened its life? I know its bad to let the pump run dry and I of course took the most precautions to make sure that didn't happen .

Please let me know! Thanks!
