Thermaltake Pacific PR22-D5 Reservoir Pump Combo Liquid Cooling System

The Thermaltake CL-W082-PL00BL-A is a reservoir and pump combination designed for builders who want a clean, reliable liquid-cooling loop without piecing the two parts together separately. Branded as the Pacific PR22-D5, it pairs a 300 ml clear acrylic reservoir with the well-known D5 pump, giving a single unit that saves space and reduces potential leak points inside a custom PC.

The reservoir uses POM for the end caps and PMMA for the tube, creating a housing that is both clear enough to show coolant color and strong enough to withstand daily vibration and heat. A pipe wall of 6 mm resists pressures up to 50 PSI, and the top cap seals against twin rubber washers so you can tip or mount the unit horizontally without worrying about drips. Two standard G1/4 in. ports accept the fittings you already own from the Thermaltake Pacific series or any other parts that follow the same thread.

At the heart of the combo, the D5 motor pushes coolant at up to 1135 L/hr and can lift fluid 15 ft, which is more than enough head pressure for large multi-radiator loops. A manual knob on the pump base lets you pick one of five speed settings, so you can run the pump quietly during everyday tasks and dial it up when you launch a game or a stress test.

Because the pump and reservoir share a single mounting bracket, installation is straightforward. Slip the bracket onto a 120 mm fan location, tuck the combo next to a front radiator, or lay it flat along the bottom of a case that supports horizontal mounting. Overclockers, gamers who color-match coolant with their build theme, and workstation users who need stable temperatures during long CPU or GPU renders will all find the PR22-D5 a solid foundation for a dependable cooling loop.
