Noctua NL-LC1-24 240 mm Liquid CPU Cooler, Brown / Beige

The Noctua NL-LC1-24 240mm all-in-one (AIO) liquid cooler is designed to manage desktop processor temperatures. A copper CU1100 base plate absorbs heat, transferring it directly to the circulating liquid loop. Two 120 mm fans force air through the aluminum radiator to dissipate thermal energy. Maximum airflow is 63.15 cubic feet per minute, with a static pressure of 3.14 mmH2O. Noise levels peak at 22.5 dB at 1800 RPM. An included NL-PNA1 absorber isolates pump vibration to keep acoustic levels low. Standard 4-pin PWM connectors allow the motherboard to adjust operating speeds based on system load.

The 400 mm woven EPDM tubes connect the radiator to the pump block. Internal 12.5 mm tubing diameters ensure consistent fluid flow regardless of the case layout. This model omits RGB lighting and built-in displays in favour of a traditional brown aesthetic. SecuFirm2+ mounting hardware secures the cold plate to Intel LGA1700, LGA1851, AMD AM4, and AM5 sockets. The unit includes all necessary installation hardware, including a Torx T20 screwdriver and vibration dampeners. Supplied NT-H2 thermal compound and a protective paste guard ensure proper contact with the processor.

Key Features:

• Ceramic pump bearing: ensures mechanical reliability within the sealed liquid chamber.
• Sterrox liquid-crystal polymer construction: reinforces the included NF-A12x25 G2 fans against deformation and resonance.
• Zero RPM minimum speed capability: allows the fans to stop completely during idle workloads for silent operation.
• 30 mm radiator thickness: fits inside standard dual-fan case mounts without obstructing motherboard components.
• 1608 g total system weight: reflects the dense copper base and the volume of coolant circulating in the loop.
• Included NA-SC1 3-way splitter cable: combines the pump and fan connections to operate from a single motherboard header.
