One of the most important components of any watercooling system is the circulation pump which is tasked with moving coolant throughout your loop. Without it your cooling system cannot function, components may fail and hardware enthusiasts will be said. Another important component that is often considered optional by many cooling enthusiasts is the coolant reservoir. This small tank holds excess coolant and makes filling your loop considerably easier.

Normally these two components are installed separately however by combining them you not only make installation easier but reduce the chance of leaks and airbubbles given the fewer hose connections.

In this review I'll be looking at the Thermaltake Pacific PR22-D5 pump reservoir combo. The PR22 comes with the Thermaltake Silent Kit pump cover that is claimed to reduces noise by 10% and makes the bottom part of the combo look really good.
