ROG Ryuo 240 liquid cooler

The ASUS ROG Ryuo 240 is an all-in-one liquid cooler built for desktop CPUs. It targets builders who want a 240 mm radiator with an integrated 1.77-inch OLED panel for live stats or custom graphics. The pump block fits a wide range of Intel and AMD sockets including LGA 1700 and AM4. Two 120 mm PWM fans and pre-applied thermal compound are included.

Practical limits of a 240 mm AIO

A 240 mm radiator can only dissipate the heat its surface area and two 120 mm fans allow. The supplied fans run between 800 and 2500 RPM, delivering 80.95 CFM at up to 37.6 dBA. Cooling capacity is bounded by case airflow, ambient temperature and the processor's actual heat output. The OLED and RGB features require a USB header and compatible software.

Copper cold plate with LGA 1700 support

The pump block uses a copper cold plate measuring 80.00 x 80.00 x 45.00 mm. Mounting hardware covers Intel LGA 2066, 2011-3, 2011, 1700, 1366, 1156, 1155, 1151-2, 1151, 1150 and AMD TR4 plus AM4. Extra LGA 1700 brackets are not in the box and must be obtained separately.

Questions about this item

Should I choose the 240 mm radiator or a different size for my case?

This model only comes with a 240 mm radiator measuring 272 x 121 x 27 mm, so verify your case supports that exact length and thickness before buying.

What does the 1.77 inch OLED panel actually show while the PC is running?

The LiveDash OLED displays real-time CPU temperature, fan speeds, pump RPM and custom images or animations you upload through the ASUS LiveDash software.

Which fan header standard do the two 120 mm fans use and what speed range do they cover?

Both fans connect via 4-pin PWM headers and run between 800 and 2500 RPM with a maximum airflow of 80.95 CFM and 37.6 dBA noise.
