ASUS TUF Gaming LC II 240 ARGB Liquid CPU Cooler: features, specs, fit

The ASUS TUF Gaming LC II 240 ARGB is an all-in-one (AIO) liquid CPU cooler with a 240 mm radiator and two 120 mm fans. It moves heat from a processor into a liquid loop that is sealed at the factory and needs no filling or maintenance by the user, then releases it through the radiator. This page covers how that design works, what ASUS lists and what to confirm for your own build.

How an all-in-one cooler works

A pump sits in the block that rests on the processor. It circulates liquid through tubing to the radiator, where the fans pull air across thin fins and carry the heat out of the case. Compared with a typical air cooler, an AIO moves the heavy part away from the motherboard and can free up room around the memory slots. It also needs a place in the case to mount the radiator, usually at the front, top or rear.

The "240" in the name refers to the radiator length. It holds two 120 mm fans side by side. In general, a larger radiator has more surface area to shed heat, which can help with sustained loads on a powerful processor.

Fans and lighting

ASUS describes the two TUF Gaming 120 mm radiator fans as having brighter Gen2 ARGB lighting and grooved fins that it says improve airflow and reduce noise. ARGB means each LED is individually addressable, so effects can vary across the fan. The lighting works with Aura Sync, so it can be matched to other compatible components. You will need a motherboard header for ARGB, and a controller or software for effects, so check your board's connectors.

Tubing and build

The cooler uses reinforced, encased 400 mm tubing. ASUS says this adds durability and helps with housing compatibility. Tube length matters in smaller cases, because the tubes need to reach from the CPU block to wherever the radiator mounts without being pulled tight or kinked. The listed package size is 4.7 x 4.7 x 1.0 in, and the weight is about 3.1 lb (1.4 kg).

Socket support

ASUS lists support for Intel LGA 1700, 1200 and 115x, and for AMD AM5 and AM4. That covers a wide span of desktop platforms, from recent Intel and AMD chips to older ones. The brand also says it is suited to TUF Gaming motherboards, which it describes as the focus of the build, though the cooler is not limited to them.

Setting it up

Installation typically involves attaching the correct mounting bracket for your socket, fitting the fans to the radiator, mounting the radiator in the case, then securing the block to the CPU with thermal paste. Follow the manual and the case maker's guidance, and check that the pump and fan cables reach the right headers.

Who it suits

A 240 mm AIO fits builders who want quieter, cooler operation than a stock cooler offers, who have a case with a 240 mm radiator mount, and who like the look of a lit-up build.

What to check before you buy

• Case: confirm it supports a 240 mm radiator and has the clearance for the fans plus radiator thickness.
• Socket: confirm that your processor's socket is on the supported list.
• Tubing: make sure the 400 mm tubes can reach your planned radiator position.
• Headers: check for a pump header, fan headers and an ARGB header on your motherboard.
• Memory and graphics clearance: check that the radiator will not collide with tall RAM or a large graphics card.
• Thermal paste and mounting parts: confirm what is in the box for your socket.
