What is AIO pump?

What Is an AIO Pump? On most AIO liquid coolers, the pump is the part that you connect to the CPU. The pump is responsible for pushing the liquid through the radiator. When it comes to any liquid cooling setup, the pump is the heart of the system. This is especially true for a closed-loop system.

How do I reset my water pump?

Hold the reset lever in the start position until the pressure builds up and the gauge reads over 40 PSI; then let it return to the AUTO position. The pump should now run on its own and continue until the pressure reaches the cut out setting, (usually between 50 – 60 PSI), and then shut off.

Why does my water stop and start?

2 Answers. If you have well water, you almost certainly have a pressure tank. The well pump runs until the pressure in the tank (and the overall system) is up to a predesignated level, then shuts off. The tank pressure then pushes water through the system until the pressure drops to a lower predetermined level.
