EK Nucleus AIO CR240 Lux D-RGB

This 240 mm all-in-one liquid cooler targets builders who want a ready-to-run thermal solution with addressable RGB styling. It fits current Intel LGA 1700 and AMD AM5 platforms alongside a wide range of older sockets. The closed loop arrives pre-filled and includes two 120 mm FPT fans for immediate installation.

Verify socket and case clearance before ordering

Confirm your motherboard uses one of the listed Intel LGA 1150, 1151, 1155, 1156, 1200, 1700, 2011, 2011-v3 or 2066 sockets or AMD AM4 and AM5 sockets. Ensure the chassis can accommodate a 240 mm radiator with two 120 mm fan slots and that the pump block dimensions of 82.3 x 69.2 x 61.6 mm do not interfere with nearby components.

Thermals, noise and power draw in normal use

The pump runs at 3100 RPM ± 10 % while the FPT fans operate between 550 and 2300 RPM ± 10 %, scaling speed with CPU temperature. Aluminium radiator and low-evaporation rubber tubing with nylon sleeve maintain coolant integrity. Addressable RGB lighting on the pump top and fans draws minimal power from the motherboard header.

Questions about this item

What comes in the box and do I need to buy anything extra to mount it on an LGA 1700 or AM5 motherboard?

The package includes the CR240 Lux D-RGB unit, two EK-FPT 120 mm D-RGB fans, a universal mounting kit covering LGA 1700 and AM5, and a user manual. No extra parts are required for those sockets.

Should I pick the 240 mm radiator version or is there a larger capacity option listed?

This model is the 240 mm radiator version with two 120 mm fan slots. The supplied facts describe only this capacity; no larger radiator option is mentioned for this product.

What does the 3100 RPM pump speed mean for actual CPU temperatures?

The pump runs at 3100 RPM ± 10 % and the fans spin between 550 and 2300 RPM, delivering high static pressure through the aluminium radiator to move heat away from modern Intel and AMD processors efficiently.
