When does water cooling make sense?

ROG Ryujin III 240

Cooler than Cool

Go cooler than cool with the ROG Ryujin III. Its roomy 3.5-inch LCD screen displays live system stats or your custom artwork and animated GIFs. Underneath, an embedded fan upgraded with Axial-tech improves motherboard VRM thermals by up to 35 Celsius, and an 8th Gen Asetek pump and coldplate combine to deliver even lower CPU temperatures. Liquid is piped in through generously long braided tubing and chilled by a higher capacity radiator and two famously quiet 120 mm Noctua fans.
