Corsair Nautilus 240 RS LCD

Manufacturer: Corsair

The Corsair Nautilus 240 RS LCD is a 240 mm all-in-one liquid CPU cooler designed for users who want effective thermal management alongside a functional built-in IPS LCD display. It ships with thermal paste included and carries a five-year warranty, reflecting a solid commitment to long-term reliability.

The cooler is equipped with two fans running on fluid dynamic bearings, capable of reaching 2100 RPM and delivering up to 72.8 CFM of airflow, while keeping audible noise between 10 dB and 36 dB depending on load. The radiator measures 275 mm in length and 125 mm in both height and width, and the unit supports a broad range of modern CPU sockets including LGA 1851, LGA 1700, AM4, and AM5. Total weight comes in at 1818 g.

Pros
  • Supports a wide range of CPU sockets including LGA 1851, LGA 1700, AM4, and AM5, covering both major platform families
  • Comes with an integrated IPS LCD display, adding a functional visual element to the cooler head
  • Fans use fluid dynamic bearings, which are associated with smoother and quieter long-term operation
  • Thermal paste is included in the box, removing the need for a separate purchase before installation
  • Noise output starts as low as 10 dB at minimum load, keeping the system quiet during light use
  • Backed by a 5-year warranty, offering extended coverage relative to many coolers in this category
Cons
  • No RGB lighting is included, which may not suit builds where lighting consistency across components matters
  • At 1818 g, the total weight is substantial and may place noticeable stress on the motherboard during transport or in certain orientations
  • Maximum noise level of 36 dB at full fan speed may be noticeable in quieter environments
  • Limited to a 240 mm radiator size, which offers less surface area for heat dissipation compared to larger radiator configurations
Who is this for?

This cooler is a solid fit for users building systems on modern Intel or AMD platforms, given its native support for LGA 1851, LGA 1700, AM4, and AM5 sockets. Those who want a clean, functional build without RGB clutter will appreciate the absence of lighting, and the inclusion of an IPS LCD display on the pump head appeals to users who want at-a-glance system readouts. The 10 dB minimum noise floor also makes it well-suited to quiet or home office environments where fan noise during light workloads is a concern.

Who is this NOT for?

Users running thermally demanding workloads that push hardware to sustained high loads may find the 240 mm radiator insufficient, as the smaller surface area limits heat dissipation capacity compared to larger radiator options. The total weight of 1818 g makes it less practical for systems that are frequently transported, where motherboard stress becomes a real concern. Additionally, builders prioritizing a fully lit, RGB-synchronized setup will need to look elsewhere, as this unit offers no lighting integration whatsoever.

Cooling:

Cooling type AIO liquid
Max fan RPM 2100 rpm
Max airflow 72.8 CFM
Number of fans 2

The Nautilus 240 RS LCD uses an AIO liquid cooling setup driven by two fans that can spin at up to 2100 RPM, generating a maximum airflow of 72.8 CFM to move heat away from the CPU efficiently.

Dimensions:

Radiator size 240 mm
Radiator height 125 mm
Radiator length 275 mm
Radiator width 125 mm

The radiator on this cooler is sized at 240 mm and measures 275 mm in length, with both the height and width coming in at 125 mm each, giving it a compact and consistent form factor suited to standard case mounting points.

General info:

CPU socket LGA 1851, LGA 1700, AM4, AM5
Audible noise (min) 10 dB
Audible noise (max) 36 dB
weight 1818 g
warranty period 5 years

This cooler is compatible with a broad range of modern CPU sockets, covering LGA 1851, LGA 1700, AM4, and AM5, making it suitable for both Intel and AMD platforms. Audible noise ranges from 10 dB at its quietest to 36 dB under full load, and the unit weighs 1818 g in total. It is backed by a 5-year warranty.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✕
Thermal paste Included
Has a display ✓
Display type IPS, LCD

The fans run on fluid dynamic bearings, and the cooler includes an IPS LCD display built in, offering a screen-based readout without requiring RGB lighting, which this unit does not feature. Thermal paste comes included in the box, so no separate purchase is needed before installation.

Final Verdict

The Corsair Nautilus 240 RS LCD presents a well-rounded AIO liquid cooling solution for builders working across both major CPU platforms, combining broad socket compatibility with a notably low noise floor and the practical addition of an integrated IPS LCD display. While its 240 mm radiator and total weight place natural limits on its suitability for the most demanding thermal scenarios or portable builds, the five-year warranty and fluid dynamic bearing fans reflect a product built with durability in mind. For users seeking a quiet, capable cooler with a functional display and no RGB distractions, the Nautilus 240 RS LCD represents a focused and well-specified choice within its category.
