240 mm AIO liquid CPU cooler

The ASUS ROG STRIX LC II 240 is an all-in-one liquid cooler with a 240 mm aluminium radiator and two 120 mm PWM fans. A seventh-generation Asetek pump runs from 840 rpm for quiet operation. It fits Intel LGA 1700, 1200, 115x, 1366, 2011, 2011-3 and 2066 sockets plus AMD AM4 and TR4 platforms. Addressable RGB lighting on the pump head is controlled via the included USB cable.

Suits builders with supported Intel or AMD sockets

This cooler serves systems using any of the listed Intel LGA or AMD AM4 and TR4 sockets. The 380 mm sleeved tubing reaches most mainstream chassis layouts. Builders whose motherboard uses a socket not listed here will need a different cooler. The package includes mounting hardware for every supported platform, a Y-cable for the two fans and pre-applied thermal compound.

272 x 121 x 27 mm radiator footprint

The radiator measures 272 mm long, 121 mm wide and 27 mm thick, so the mounting area in your case must accommodate those dimensions. Two 120 mm fans push up to 80.95 CFM at 2500 rpm with a noise level of 37.6 dB(A). If the available space is smaller than the radiator size, this unit will not fit.

Questions about this item

Does this cooler include the mounting brackets for an Intel LGA 1700 motherboard?

Yes, the accessory pack supplies Intel LGA 1700 brackets alongside LGA 1200, 115x, 2066, 2011, 2011-3 and 1366 hardware.

Will the 272 mm radiator and 380 mm tubes fit inside a mid-tower case built for 240 mm AIOs?

The radiator measures 272 x 121 x 27 mm and tubes are 380 mm long, matching standard 240 mm mounting holes used on current mid-tower chassis.

How can I confirm the seventh-gen Asetek pump is running at its 840 rpm minimum after installation?

Connect the USB cable to the motherboard, open the ASUS control software, and read the live pump-speed value; it should show 840 rpm or higher at idle.
