I am on a Ryzen 5 build on a b550 motherboard. That might explain it, but i think mine is just faulty.
On the pump front, I had the pump spin dry for longer without it beeping or anything. So I decided to try it out under water again it magically worked now....
Guess running it dry for a bit fixed it? This is the old pump btw, the new one doesn't even spin dry. It might be DOA. due to a different issue but annoyingly gave the same warning message...
On the disconnecting from pc issue, I couldn't get the old unit to connect to my pc at all, no matter what i did. I tried the new one on the same internal USB header and it worked great.
So to fix all my issues i needed the pump of the old unit and the control part of the new one....Had to buy two to get a fully working one
I wonder if i could send back the new control unit and old pump somehow....
Now if only all the RGBs would work... the Ultitube ring and connected aqua computer cpu block should have rgv,,, I even daisy chained them together but they have only ever worked sporadically...
I think I shouldn't get greedy and be happy with my computer being usable again.
