For 240 mm AIO builds

The ASUS ROG Ryujin 240 is a closed-loop liquid cooler built around a 240 mm aluminium radiator and two 120 mm Noctua industrial PWM fans. It targets enthusiasts who want a pre-filled unit with an integrated 1.77 inch colour OLED panel and addressable RGB lighting for real-time system stats and custom animations.

Mounting and noise notes

The pump block measures 100.00 x 100.00 x 70.00 mm and includes pre-applied thermal compound, so installation starts by fitting the supplied brackets for the chosen socket. An embedded microfan inside the housing blows air toward the VRM and M.2 area, while FanXpert software lets the 450–2000 RPM fans run as low as 29.7 dBA under light loads.

Socket compatibility decides fit

The cooler supports Intel LGA 2066, 2011-3, 2011, 1700, 1366 and 115x plus AMD AM4 and TR4, although the TR4 bracket ships with the CPU package rather than the cooler box. Builders using LGA 1700 should verify they have the correct bracket before starting, as the extra hardware is not included in every retail pack.
