Know before you buy
Because this radiator is 58mm thick, you must ensure your case has enough clearance for both the radiator and your fans. Always check your case manufacturer's specifications for radiator support, specifically accounting for the total thickness of the radiator plus 25mm for standard fans.
This radiator features an 18 FPI (fins per inch) density, which performs best when paired with high-static pressure fans. It is specifically engineered to excel in high-airflow scenarios, so using fans capable of pushing air through the thicker core will yield the best thermal results.
The multiport configuration provides significant flexibility for tube routing, allowing you to choose the most efficient path for your loop. Having extra ports also makes the maintenance process much easier, as you can dedicate one port specifically for a drain valve.
No, the radiator is designed with sixteen 2mm wide copper tubes to minimize flow restriction. This ensures that your pump does not have to work excessively hard to circulate coolant, which helps maintain pump longevity.
While this radiator contains aluminum in its end caps, the internal water-contacting parts are copper. To prevent galvanic corrosion, you should avoid mixing aluminum components in your water cooling loop and stick to copper, brass, or nickel-plated components.
