DEEPCOOL Spartacus 420 420mm CPU Liquid Cooler ( Black ) ( With LCD Display )

The Deepcool Spartacus 420 is a 420mm all-in-one liquid CPU cooler built for enthusiast-grade systems that demand both sustained thermal performance and a visually expressive build. At its heart sits a sixth-generation pump running a 3-phase, 6-slot, 4-pole motor with Field Oriented Control (FOC), spinning between 2,500 and 3,400 RPM via a 4-pin PWM connector. The enlarged copper cold plate and refined microfin geometry are engineered to dissipate up to 350 W of heat, covering the thermal demands of Intel Core Ultra 9 285K and Core Ultra 7 265K as well as the full AMD Ryzen lineup on AM4 and AM5. Three 30mm-thick 140mm fans constructed from PPS plastic each integrate their own 3-phase 6-slot 4-pole closed-loop motor, spinning between 500 and 2,000 RPM with a zero-RPM mode at PWM duty cycles below 5%. Each fan delivers up to 112.5 CFM of airflow at 4.15 mmAq static pressure while remaining at or below 32.89 dB(A). Hydro bearings keep friction and operating noise to a minimum over the long term, and all fans connect via 4-pin PWM headers. The pump head houses a 3.4-inch IPS LCD panel running at 480×480 resolution with 16.7 million colours, 750 nits brightness, and a 30 Hz refresh rate. The Deepcool DeepCreative software lets you configure the display in modular block layouts—monitor CPU temperature, frequency, usage, and pump speed in real time, or play images, animated GIFs, or MP4 video. Zen Mode automatically reduces update frequency under heavy system load to protect performance headroom. An ARGB LED system (5 VDC, 3-pin +5V-D-G) adds per-channel addressable lighting. A single 10-pin connector routes power and signal for both pump and display, reducing cable clutter. The compact hub manages fan speed and ARGB output independently per channel and supports magnetic or screw mounting. The magnetic pump cap allows easy removal, while precision pogo-pin contacts maintain a reliable electrical connection. A newly engineered offset bracket for LGA1851 platforms aligns the cold plate with the CPU hotspot on 24- or 20-core Intel processors, reportedly reducing temperatures by 1–3°C versus a centred mount (vendor claim; not independently verified). Deepcool's patented Anti-Leak Technology uses an internal valve to regulate and purge pressure when it exceeds atmospheric levels, extending cooler service life. Socket compatibility spans Intel LGA1851, LGA1700, LGA1200, LGA1151, LGA1150, and LGA1155, plus AMD AM5 and AM4—covering Intel Core i3 through i9, Core Ultra 5/7/9, and AMD Ryzen 3 through Ryzen 9. The unit carries a 5-year warranty.
