240 mm ARGB liquid cooler for overclocked CPUs

The be quiet! Light Loop 240mm White is a closed-loop liquid cooler built for heavily overclocked systems. It mounts on AMD Socket AM4, AM5 and Intel LGA 1150, 1151, 1155, 1200, 1700 and 1851 platforms. Forty-eight addressable RGB LEDs illuminate the cooling block and both fans for a coordinated light show.

Two 120 mm PWM fans and an integrated ARGB-PWM hub

Two Light Wings LX 120 mm PWM high-speed fans in white push air through the 240 mm radiator. Each fan carries 16 LEDs and nine airflow-optimised blades that reduce turbulence. The included hub consolidates ARGB and PWM cables so the motherboard sees a single connection for lighting and speed control.

Sustained cooling under peak CPU loads

The loop delivers impressively high cooling power that keeps temperatures low during extended periods of peak CPU performance. Fan curves can be tuned via PWM for quieter operation when the load eases. Builders who need a larger radiator or a different socket not listed here should look at other models.

商品問答

What is the radiator length that limits case clearance for the Light Loop 240mm?

The radiator is 240 mm long and uses two 120 mm fan slots, so your case must support a 240 mm radiator with 120 mm fans.

How many ARGB LEDs are in the cooling block and fans, and do they add noticeable heat?

The block and two Light Wings LX fans contain 48 ARGB LEDs in total; LED heat output is negligible and does not affect coolant temperature.

Which CPU socket mounting hardware is included with the BW021 cooler?

The package includes brackets for AMD AM4, AM5 and Intel LGA 1150, 1151, 1155, 1200, 1700 and 1851 sockets.
