What customers say
This premium radiator is highly regarded by experienced builders for its exceptional performance and superior build quality. The innovative X-Flow design is a standout feature, significantly simplifying complex tubing runs, especially in compact systems. Users confirm the 'P' series delivers excellent thermal dissipation, often surpassing comparable units. The matte black finish provides a professional, high-end aesthetic that integrates well into enthusiast builds. While the price reflects its top tier status, customers generally agree the specialized functionality, clean routing benefits, and cooling power justify the investment. It is viewed as a best in class component for those prioritizing simplified plumbing and strong thermal headroom.
Know before you buy
The X-Flow design allows coolant to enter one end of the radiator and exit from the opposite end, rather than looping back to the same side. This simplifies tubing runs and reduces the amount of hose or hardline needed to complete your custom loop.
This radiator features eight G1/4" ports, providing significant flexibility for your loop configuration. You can choose the most convenient inlet and outlet points for your specific case layout, while the remaining ports can be used for drain valves, temperature sensors, or air bleeding.
The 44mm thickness is considered a mid-range profile. While it offers excellent cooling performance, you should verify that your case has sufficient clearance for both the radiator and your chosen fans to avoid interference with motherboard components or RAM.
An 18 FPI (fins per inch) density is engineered to strike a balance between thermal dissipation and airflow resistance. It performs efficiently with a wide range of fan speeds, meaning you don't need extremely high-static pressure fans to achieve effective cooling.
As with any custom loop component, you should flush the radiator with distilled water before installation to remove any manufacturing residue. Additionally, ensure you use a high-quality coolant with anti-corrosive inhibitors to maintain the integrity of the copper fins and brass chambers over time.
