Thermaltake Pacific PR22-D5 Plus D5 Pump/Reservoir Combo - RGB Control

Our review of the Thermaltake Pacific PR22-D5 Plus finds it aimed squarely at PC water-cooling enthusiasts who want a compact, high-performance pump/reservoir that also serves as a lighting centerpiece. The single biggest reason to consider this unit is the combination of a D5-class pump performance and a 300 ml reservoir with 12 separately controllable RGB LEDs, which lets builders balance strong flow with visual customization. It is best for custom loop builders who value quiet operation and configurable lighting and are comfortable with careful installation and occasional maintenance.

Key Features

• Integrated D5 pump: Delivers up to 1135 L/h flow for strong coolant circulation in demanding loops.
• 12 addressable RGB LEDs: Provide precise lighting control to match system themes with 16.8 million color options.
• Five speed control: Adjustable pump speeds let users prioritize quiet operation or maximum flow depending on needs.
• POM and PMMA construction: Durable plastics offer a clear display and a robust body that resists common loop chemicals.
• Anti-vibration mounting: Includes brackets to reduce noise transfer and keep the pump running quietly in most installs.

Who It's For

The Pacific PR22-D5 Plus is best for PC builders who run mid to large custom loops and want both high flow rates and a showpiece reservoir with addressable RGB. It suits users who appreciate quiet pumps and the flexibility of five-speed control and are prepared to manage fittings carefully during installation.

It is less appropriate for users seeking a maintenance-free or ultra-compact solution; those who require absolute long-term reliability without occasional part replacement, or who are uncomfortable troubleshooting leakage, may prefer simpler sealed pump units or alternative brands with different service records.

Pros & Cons

Pros

• Strong flow rate and lift make it effective in larger loops that need reliable circulation.
• Addressable RGB and clear PMMA reservoir create a striking visual focal point for a build.
• Five-speed control and anti-vibration mounts let builders tune noise versus performance.

Cons

• Some users report mixed installation effort and occasional leakage, so careful assembly and inspection are required.
• There are customer concerns about long-term durability under continuous heavy use.

Our Verdict

The Pacific PR22-D5 Plus is a compelling choice for custom loop builders who want strong flow, fine pump control and addressable lighting in one integrated unit. It offers good value for those who prioritize performance and looks, but prospective buyers should accept that careful installation and attention to long-term maintenance are part of the trade-off.

Frequently Asked Questions

Is the pump loud?
Most users experience quiet operation, especially at lower speeds thanks to anti-vibration mounting, but noise can increase at higher pump settings.

Can it handle large loops?
Yes; the 1135 L/h flow and 15 ft head make it suitable for mid to large custom cooling loops.

Are there common reliability issues?
Some customers report units failing after extended continuous use and occasional leakage reports, so routine checks and proper installation are advised.
