Know before you buy
The XFlow design features a cross-flow tank configuration, which allows coolant to enter one side and exit the other. This setup often simplifies loop routing and can improve flow rates compared to traditional U-turn radiator designs.
Yes, it is designed for 360mm mounts, but you should verify your case clearance. With a thickness of 30mm, it is relatively slim and compatible with most mid-tower and full-tower cases that support 360mm radiators.
Yes, the radiator uses industry-standard G 1/4" threaded ports, making it compatible with the vast majority of aftermarket compression and barb fittings available on the market.
It is optimized for versatility. The 16 FPI (fins per inch) count is balanced to provide excellent thermal dissipation even with low-noise, low-RPM fans, while still scaling well if you choose to use high-speed fans.
Because the radiator is made of copper, it is highly resistant to corrosion. However, you should always use a high-quality coolant with anti-corrosive inhibitors to maintain the health of your entire loop and prevent galvanic corrosion if other metals are present.
The radiator uses standard M4 mounting threads. Most radiator mounting screws included with cases or fan kits are compatible, but always ensure your screws are the correct length to avoid damaging the radiator fins.
