Here are several reasons why the corsair h100i v2 pump may keep making noise.

1. High pressure in the pump

The pump is essential in releasing pressure from the brakes. Also, it maintains the pressure of the Cooler pump to make it function as required. Sometimes, the pressure may increase, resulting in the valve failing. Once the pressure increases, there is an emission of loud noise. The noise may improve with time, and the only way to solve the issue is to reduce the pressure.

2. Blocked pump

Another reason why the pump may emit noise is the accumulation of dirt. Once the pump is clogged, there is too much noise. First, check the pump’s condition and try unclogging using a thin brush.

4. Bad shims

If the shims are in poor condition resulting in metal-to-metal contact with the gears while driving and in the process, there is too much noise emission. The metal-to-metal connection requires an expert to solve the issue immediately since they know how to handle the metals to bring the pump to correct functioning.

5. Loose screws

The common reason your pump may keep making noise is due to loose screws holding the pump in position. If the screws become loose, the pump may keep swaying from side to side while driving, resulting in the emission of loud noise that irritates a lot.
