Size, Lighting, and Pump Specs
Radiator size
The Corsair iCUE H100i features a 240mm radiator, while the Corsair Nautilus 360 RS uses a 360mm radiator. A larger radiator generally provides more surface area for heat dissipation. This means the Nautilus 360 RS can potentially handle higher thermal loads more effectively than the H100i. You should consider your case’s mounting space, as the 360mm unit requires a wider opening. The H100i is more compact, fitting into smaller chassis that cannot accommodate a 360mm radiator. If you have ample space, the larger radiator offers better cooling headroom. Otherwise, the 240mm option is more versatile for compact builds.
Lighting technology
Lighting differs significantly between these two models. The H100i uses RGB fans and a pump head with individually addressable LEDs. Each fan has 16 LEDs. The Nautilus 360 RS uses ARGB fans. ARGB allows for more complex color effects and streaming patterns on the fans. The H100i pump also features dynamic multi-zone RGB lighting. You control lighting via Corsair iCUE software for the H100i. The Nautilus RS fans support easy ARGB control via a compatible motherboard header. If you prefer motherboard-controlled ARGB sync, the Nautilus is better. For detailed pump lighting effects, the H100i offers more visual customization on the pump head itself.
Pump noise level
Noise is a key factor for many builders. The Nautilus 360 RS pump generates a whisper-quiet 20 dBA. This low noise level ensures the pump does not add audible hum to your system. The H100i data does not list a specific pump noise rating in decibels. It does mention a zero RPM fan mode to eliminate fan noise at low temperatures. However, the pump noise remains unknown from the provided specs. If silent operation is your priority, the Nautilus 360 RS provides a clear advantage with its documented 20 dBA pump noise. You can expect a quieter baseline operation with the Nautilus compared to the unspecified pump noise of the H100i.
Socket compatibility
Socket support varies between the two coolers. The Nautilus 360 RS explicitly supports Intel LGA 1851, LGA 1700, and AMD AM5 and AM4 sockets. This covers both current and previous generation platforms. The H100i data does not list specific socket compatibility. You must check the manual or packaging for older socket support if you choose the H100i. For new builds using the latest Intel or AMD platforms, the Nautilus 360 RS guarantees compatibility. If you are upgrading an older system, you need to verify the H100i supports your specific socket. The Nautilus offers broader, documented support for modern hardware.
Fan airflow
Airflow impacts cooling efficiency. The H100i fans deliver 63 CFM of airflow. This is a specific performance metric for the LL120 RGB fans. The Nautilus 360 RS fans use Corsair AirGuide technology and magnetic dome bearings. They provide strong airflow and high static pressure, but no specific CFM number is listed. Higher static pressure helps push air through dense radiator fins. The H100i’s 63 CFM is a measurable benchmark. The Nautilus fans are optimized for pressure, which may be more effective for radiators. Without exact CFM numbers for the Nautilus, the H100i has a quantifiable airflow advantage, while the Nautilus relies on pressure optimization.
Which Corsair AIO fits your needs
Users with large cases and high-end CPUs
The Nautilus 360 RS features a 360mm radiator, which offers more surface area for heat dissipation than the 240mm unit. Its low-noise pump operates at just 20 dBA, ensuring quiet operation. The convex cold plate with pre-applied thermal paste simplifies installation and improves contact. This larger size is ideal for demanding thermal loads.
Owners of compact cases with 240mm mounts
The iCUE H100i fits in cases that only support 240mm radiators. It uses two LL120 fans that can reach 2,200 RPM for strong airflow. The zero RPM mode stops fans completely at low temperatures to eliminate noise. Its compact 240mm size makes it a practical choice for smaller builds where space is limited.
Those wanting simple motherboard ARGB control
The Nautilus 360 RS uses RS120 ARGB fans that allow easy control via a compatible motherboard header. You can daisy-chain the fans to reduce cable clutter. This setup connects to just one 4-pin PWM header and one ARGB header. It is a clean solution for users who prefer motherboard software over additional controllers.
