PURE LOOP 3 LX 240mm AIO cooler

The be quiet! PURE LOOP 3 LX 240mm is a new all-in-one liquid cooler built for heavily overclocked consumer CPUs. It uses a 240mm radiator with two 140mm Light Wings LX PWM high-speed fans. A state-of-the-art PWM pump with a 6-pole motor keeps vibration to a minimum. An easy-access refill port simplifies long-term maintenance.

Suits overclocked CPUs; not for compact cases

This cooler suits builders running heavily overclocked processors on supported AMD AM4, AM5 or Intel LGA 1150, 1151, 1155, 1200, 1700 and 1851 sockets. The ARGB block includes ten lighting foils for customisation. Builders needing a smaller radiator for restricted chassis space should look at other form factors.

240mm radiator with dual 140mm fans

The single specification that decides fit is the 240mm radiator paired with two 140mm fan slots. This physical size determines whether the unit fits your case and clears motherboard components. Verify your chassis supports a 240mm mounting location before purchase.

Questions about this item

How loud and hot do the 140 mm Light Wings LX fans and PWM pump get under continuous load?

The 6-pole PWM pump is designed to minimise vibration, and the two 140 mm Light Wings LX fans use funnel-shaped outlets for efficient airflow, keeping noise and heat low during extended operation.

Which CPU socket and mounting hardware must already be present for the BW030 block to install?

The cooler supports AMD AM4, AM5 and Intel LGA 1150, 1151, 1155, 1200, 1700 and 1851 sockets, so the matching motherboard and retention kit must be in place.

Will the 240 mm radiator and ARGB block fit alongside older LGA 1150 or AM4 components in a standard case?

The 240 mm radiator uses two 140 mm fan slots and the block includes 10 lighting foils; clearance depends on case dimensions and motherboard layout around the supported sockets.
