Corsair CX-9031001-WW Hydro X XR5 140mm Radiator

The Corsair Hydro X Series XR5 140mm radiator is engineered for custom liquid cooling enthusiasts who need a compact, high-quality heat exchanger for their loop. At its core is a copper radiator with 25-micron-thick cooling fins, delivering a high surface area for thermal transfer that outperforms aluminum alternatives. The 30mm radiator thickness strikes a practical balance — slim enough to fit in tight case locations while still providing meaningful cooling headroom, whether paired with quiet low-RPM fans or high-airflow models.

Installation is made straightforward by integrated fan screw guides that ensure proper alignment on both sides of the radiator, along with screw protection plates that prevent accidental damage to the fins. The exterior features a durable polyurethane coating in a clean black finish that complements most build aesthetics. With standard G1/4" threaded ports, the XR5 140mm integrates seamlessly with Corsair's Hydro X ecosystem and most third-party fittings. This radiator is particularly well suited as a secondary unit in a multi-radiator loop, or as a primary cooler for lower-TDP components where space is at a premium.
