The DeepCool SPARTACUS 420 AIO Liquid CPU Cooler is a 420mm all-in-one liquid cooler designed for high-end Intel and AMD builds that want both cooling performance and visual customization. It combines a 3.4-inch LCD screen with offset bracket technology optimized for Intel's latest high-core-count CPUs, and a Gen 6 pump paired with three 140mm PWM fans.

Why This Product

• 3.4-inch customizable LCD display — The integrated IPS screen offers 480×480 resolution with 16.7 million colors and modular layout blocks, updating data every second so you can monitor system metrics or display custom visuals in real time.
• Offset bracket for Intel high-core LGA1851 — The newly engineered bracket aligns with hotspots on Intel Core Ultra 9 285K and Core Ultra 7 265K CPUs, reducing temperatures by 1-3°C while maintaining full compatibility with standard Intel and AMD platforms.
• Single 10-pin connection for pump and screen — Power and signal for both pump and display run through one connector, eliminating cable clutter and simplifying installation through a compact control hub.
• Anti-leak patented valve technology — An internal pressure regulator purges excess pressure above atmospheric levels, extending cooler lifespan and reducing leak risk over time.
• Three 140mm PWM fans with hydro bearings — Each fan runs at 500-2000 RPM with a 3-phase 6-slot motor and closed-loop control, delivering 112.5 CFM of airflow while maintaining noise at or below 32.89 dB(A).

Best For / Trade-offs

Best for:

• Builders seeking RGB customization and real-time system monitoring via a built-in screen
• Intel Core Ultra 9 285K and Core Ultra 7 265K users who benefit from the offset bracket's 1-3°C temperature advantage
• High-end setups prioritizing cable management and single-connection pump control
• Users valuing quiet operation; fans run at or below 32.89 dB(A) across the full speed range

Trade-offs:

• Compact cases or builds without 420mm radiator space
• Builders indifferent to LCD displays or those seeking a simpler, no-screen cooler design
• Budget-conscious builds; this cooler's premium feature set commands a higher price point

Description

SPARTACUS 420 is DeepCool's latest generation of liquid coolers featuring an advanced customizable LCD screen. Personalize your build with modular layouts and dynamic visuals on the 3.4" IPS screen. Equipped with an upgraded Gen 6 pump and high-performance fans, it ensures exceptional cooling efficiency and quiet operation.

A Form that Speaks
With a precision-crafted design and refined metal finish, SPARTACUS 420 reflects DeepCool's commitment to modern aesthetics and build quality. The pump cap attaches magnetically for easy removal, and precision pogo pin contacts ensure a stable and reliable connection.

Vividly Fluid 3.4" LCD
A 3.4" IPS display opens a new screen experience, featuring 480×480 resolution and support for 16.7 million colors. Content is structured in modular blocks, enabling a flexible visual layout tailored to individual preferences. Data updates every second and supports multiple layout sizes.

Single Connection, Total Control
The unique 10-pin connector integrates power and signal for both pump and screen, eliminating cable clutter with a single, streamlined connection. Control is centralized through a compact hub, allowing independent adjustment of fan speeds and ARGB lighting per channel, with magnetic and screw mounting options for flexible installation.

Precision Cooling Alignment
SPARTACUS 420 features a newly engineered offset bracket optimized for Intel 24- or 20-core LGA1851 CPUs (such as the Core Ultra 9 285K or Core Ultra 7 265K). By offsetting the cold plate upward, it aligns precisely with the CPU's hotspot and reduces temperatures by 1-3°C. Other Intel and AMD platforms remain fully supported with standard mounting hardware.

Rear-Lock Mounting
The rear-mounted locking system allows front-side installation without screws, streamlining the process and resulting in a cleaner build.

Anti-Leak Technology
The SPARTACUS liquid coolers feature DeepCool's patented Anti-Leak Technology. The internal valve regulates pressure and purges it when internal pressure exceeds atmospheric pressure, extending the cooler's lifespan and reducing the risk of leaks.

SPARTACUS 420 is equipped with three 30mm-thick 140mm PWM fans built with PPS for enhanced structural stability at high speeds. Each fan integrates a precision 3-phase 6-slot 4-pole motor with closed-loop control to maintain strong airflow and responsive performance. Hydro bearings support smooth, reliable operation over the long term.
