I managed to get all the air bubbles out of the system but still can't get the pump to flow more than 160lph. It's connected to a regular power connection.
I have the same issue. 160lph is all it will output on setting 5. It's not enough to fill the CPU cooling block before it drains out the other side. I can't really run it this way because the CPU block isn't full. I'm wondering if it's defective.
