Know before you buy
The XR5 420 V2 measures 450mm x 140mm x 30mm. Before purchasing, ensure your case supports a 420mm radiator and has enough clearance for the 140mm width, as many standard cases are designed for 120mm-based radiators.
No. This radiator is constructed from copper and brass, so it must only be used in a loop with other copper or brass components to prevent galvanic corrosion.
This radiator uses standard G1/4" BSPP threads, which are the industry standard for custom water cooling. You can use any standard G1/4" fitting compatible with your tubing type.
The 30mm thickness is a slim profile designed for broad case compatibility while maintaining high thermal efficiency. It uses a dual-fin arrangement and 25-micron fins to maximize surface area, ensuring excellent heat dissipation even in tighter spaces.
Yes, the radiator is designed with flexible mounting points on both sides, allowing you to install fans on both the front and back for a push-pull configuration to increase airflow.
Yes, the unit includes integrated screw protection plates located under the mounting holes. These prevent you from accidentally driving a fan screw too deep and puncturing the radiator core.
