Frequently Asked Questions

Which CPU sockets does the be quiet! Light Loop 240mm support?

The product listing used here does not state socket compatibility. Check be quiet!'s official spec sheet for the current list of supported Intel and AMD sockets before you buy.

How many LEDs does the Light Loop 240mm have, and can I change the colors?

There are 48 LEDs in total. Each of the two Light Wings LX 120mm fans has 16, and the rest are in the lit cooling block. Colors and effects are set through your motherboard's ARGB header, which connects through the included ARGB-PWM-Hub.

How many fans and RGB devices can the included hub control?

The ARGB-PWM-Hub syncs up to 6 PWM fans and 6 ARGB components. It needs only one PWM header and one ARGB header on the motherboard. You can mount it with adhesive tape or with screw holes that match a 2.5-inch SSD mount.

Is the pump loud?

be quiet! uses a progressive IC in the pump motor to reduce switching noise and keep pump noise low. The fans' nine airflow-optimized blades are also designed to reduce the turbulence that causes noise.

Will the Light Loop 240mm fit in my case?

Your case needs a 240mm radiator mount, meaning two 120mm fan positions side by side, on the top, front or side. Radiator and tube dimensions are not listed here, so check be quiet!'s spec sheet against your case's radiator clearance.
