Compact Cross-Flow Radiator for 120 mm Fans

The Darkside Cross-Flow Dual LPX240 is a 240 mm radiator built for two 120 mm fans in a cross-flow layout. Its reduced thickness and width target compact builds where clearance around memory modules and other components is tight. The unit is new and includes mounting screws.

Cross-Flow Layout and Slim Profile Change Routing

Cross-flow configuration places inlet and outlet ports at opposite ends, simplifying tube runs in small cases. Irregular side tanks improve coolant flow while shrinking the overall footprint. UNC 6-32 threads on both sides allow push-pull fan mounting when space permits.

27.5 mm Thickness Decides Fit in Tight Builds

At 27.5 mm thick the radiator fits where standard models cannot, making this dimension the primary filter for compatibility. The 150 mL capacity and 17 FPI core support both low-noise and high-performance fans. Two G1/4 ports accept any standard fitting.

Questions about this item

How often should I flush the LPX240 radiator to maintain its cross-flow core?

Flush the loop once a year with distilled water or a mild coolant cleaner; the 17 FPI fins trap particles, so regular cleaning keeps flow through the 150 mL capacity consistent.

What thermal limit appears first when the 240 mm radiator runs at full load for hours?

The 27.5 mm thick core and 17 FPI density saturate first; coolant temperature rises until the two 120 mm fans can reject no more heat through the slim profile.

How loud and hot does the LPX240 get with two 120 mm fans spinning all day?

Noise and heat depend entirely on the 120x120x25 mm fans you choose; the radiator itself adds no sound, and its cross-flow tanks spread warmth evenly across the 291 mm length.
