Noctua Enters Liquid Cooling With NL-LC1 Series
Noctua’s NL-LC1 series is a new all-in-one liquid cooling solution that combines a closed-loop CPU water cooler, integrated pump, and radiator-mounted fans, aiming to deliver quiet, reliable thermal performance for modern processors while preserving the brand’s focus on low noise, build quality, and long-term support. After more than two decades building its reputation on air coolers and fans, Noctua is breaking tradition and entering the AIO space with the NL-LC1 line. According to Wccftech, the company will offer three models, with the 240mm version priced at €219, the 360mm at €249, and the 420mm at €279. All three use Noctua’s NF-A12x25 G2 or NF-A14x25 G2 fans and arrive with a six-year warranty, positioning the Noctua AIO cooler range as a premium, low-noise option against established liquid cooling brands.
Sizes, Fans, and Pump Technology: 240mm, 360mm, 420mm
The NL-LC1 family targets mainstream to high-end builds with three radiator sizes: 240mm, 360mm, and 420mm. The 240mm and 360mm units use 120mm NF-A12x25 G2 fans, while the 420mm model steps up to 140mm NF-A14x25 G2 fans, addressing cases that support larger radiators and slower-spinning fans. Noctua pairs these with Asetek’s Emma (G8) V2 pump platform, which features a redesigned impeller and 3-phase motor to cut vibration harmonics, coil whine, and resonance. Pump control is handled via an analogue PWM controller tuned for stability and long-term durability instead of a software-dependent approach. Users can pick from three pump-speed profiles—quiet, balanced, and manual—to fine-tune the performance-to-noise ratio. Together, these elements create a liquid cooling solution that aims to match high-end thermal performance while maintaining Noctua’s trademark acoustic focus.
Noise-Reduction Design and Optional Auxiliary Fan
While many CPU water cooler designs struggle with pump noise and tonal hum, Noctua’s first AIO focuses strongly on acoustics. The Emma V2 pump is wrapped in a triple-layer housing that works as a noise absorber, acting as both soundproofing and tuned-mass damper to reduce airborne and structural vibrations. Fan speed offset logic helps avoid beat-frequency hum when multiple fans are running at similar speeds, smoothing overall acoustic output. Radiators use a non-louvred fin design to keep air impedance low and reduce dust build-up over time. For systems with hot VRMs, RAM, or M.2 SSDs, Noctua will sell the NL-ACF1, an 80mm auxiliary fan that magnetically snaps onto NL-LC1 units. Its custom frame uses the Coanda effect to pull more air outwards around the socket area, adding targeted cooling without sacrificing the AIO’s quiet profile.
Next-Gen Heatsinks and Thermosiphon Research
Noctua’s Computex presence is not limited to the NL-LC1 Noctua AIO cooler range. The company also showed a next-generation NH-L12 low-profile heatsink for AMD AM5 systems, now with six heatpipes, total height reduced to 70mm including fan, and 35mm RAM clearance. It uses the NF-A12x25 G2 fan and a revised base for better contact on AM5 and AM4, keeping air cooling competitive in compact builds. For workstations, Noctua presented a dual-tower design with seven heatpipes and a large baseplate ready for future AMD Threadripper and Intel workstation sockets, combined with NF-A14x25r G2 and NF-A12x25 G2 fans. Alongside these, the company discussed ongoing thermosiphon development as an alternative passive liquid cooling concept, suggesting future products that may bridge the gap between traditional air coolers and pump-driven liquid cooling solution designs.
Carbice Thermal Pad and What NL-LC1 Means for Noctua
Beyond coolers, Noctua is collaborating with Carbice on the NT-CP1 carbon nanotube thermal pad for AM5 and AM4. This pad targets users who want long-term consistency without the maintenance of conventional thermal paste. It resists dry-out, pump-out, and cracking, and is said to improve through thermal cycling rather than degrade, making it a logical partner for long-lived coolers such as the NL-LC1 series. Noctua is also exploring Intel-focused versions of the pad. Together with the upcoming PRIME TX PSUs and thermosiphon work, these moves show Noctua widening its ecosystem around cooling reliability, not abandoning air towers. For builders weighing air versus liquid, the NL-LC1 CPU water cooler family signals that Noctua now offers a full spectrum—from refined heatsinks to quiet-focused 240mm, 360mm, and 420mm AIOs—for high-performance PCs.
