240 mm liquid cooler for mainstream CPUs

This all-in-one cooler targets builders who want closed-loop liquid cooling on mainstream Intel and AMD platforms. The copper cold plate and aluminium radiator cover sockets from LGA 1150 through LGA 2066 and AMD AM2 to TR4. Two 120 mm fans provide airflow across the 274×120×27 mm radiator. It suits users who prefer a single integrated unit over custom loops.

ARGB lighting and PWM control

Addressable RGB LEDs on the water block and fans synchronise through a 3-pin ARGB header and Shenguang Sync software. A 4-pin PWM interface lets the motherboard vary fan speed between 900 and 1800 RPM based on CPU temperature. The pump runs at 12 V and 250 mA. These connections replace manual switches and fixed-speed operation.

68.04 CFM airflow with 33.16 dB noise

At maximum speed the dual fans move 68.04 CFM across the 240 mm radiator while producing 33.16 dB of noise. The 380 mm tubing length fits most mid-tower cases. The cooler handles typical gaming and productivity loads on compatible sockets. It runs out of headroom on heavily overclocked high-core-count CPUs that exceed the radiator’s dissipation capacity.

Questions about this item

Will the 27 mm thick 240 mm radiator need any coolant top-up or pump service later?

The loop is sealed at the factory and uses a 12 V pump rated at 250 mA, so no coolant refill or pump maintenance is required during normal life.

What thermal limit appears first when the 900-1800 RPM fans run continuously at high load?

The 274×120×27 mm aluminum radiator and 68.04 CFM airflow set the ceiling; once the coolant saturates, temperatures rise regardless of fan speed.

How loud and hot do the two 120 mm ARGB fans get during all-day operation?

At maximum 1800 RPM the fans produce 33.16 dB noise; PWM control lowers speed and sound when the CPU is cooler, and the 12 V pump adds minimal extra heat.
