Deepcool Spartacus 420 CPU Liquid Cooler With LCD Display

The DeepCool Spartacus 420 is a high-performance 420mm all-in-one CPU liquid cooler designed for enthusiast and workstation builds that demand serious thermal headroom and a striking visual presence. At the heart of the cooler sits a sixth-generation pump built around a 3-phase, 6-slot, 4-pole motor with Field-Oriented Control (FOC), operating across a PWM-adjustable speed range of 2,500 to 3,400 RPM (±10%). An expanded copper cold plate with refined microfin geometry pushes the cooler’s rated heat dissipation capacity to 350W, making it well-suited for high-core-count processors such as the Intel Core Ultra 9 285K or AMD Ryzen 9 series. The pump head incorporates a 3.4-inch IPS LCD display running at 480×480 resolution with 16.7 million colors, a 30 Hz refresh rate, and a peak brightness of 750 nits. The display is managed through DeepCool’s DeepCreative software, which organises content in modular blocks — users can show live CPU temperature, usage, clock frequency, GPU power draw, network speeds, RAM utilisation, or custom media including images, GIFs, and MP4 videos. A Zen Mode reduces display update frequency under heavy system loads to keep resource overhead minimal. Three 140×140×30 mm PWM fans — constructed from PPS polymer for rigidity at high speeds — deliver up to 112.5 CFM of airflow at up to 2,000 RPM (±10%), with a noise ceiling of ≤32.89 dB(A) and a static pressure rating of 4.15 mmAq. Each fan uses a hydro bearing for long-term reliability. A 10-pin single connector integrates power and signal for both pump and display, while a centralised hub allows per-channel fan speed and ARGB lighting adjustment. Addressable RGB LEDs run on a 3-pin (+5V-D-G) connector at 5 VDC. A newly engineered offset bracket specifically optimises cold-plate alignment for Intel LGA1851 CPUs with 24- or 20-core die layouts (e.g., Core Ultra 9 285K, Core Ultra 7 265K), reportedly reducing temperatures by 1–3°C on those platforms. All other supported sockets — LGA1700, LGA1200, LGA1151, LGA1150, LGA1155, AM5, and AM4 — are served by standard mounting hardware. DeepCool’s patented Anti-Leak Technology uses an internal valve to regulate and release pressure when it exceeds atmospheric levels, extending operational lifespan. The pump cap attaches magnetically with pogo-pin contacts for tool-free removal and a stable signal path. The rear-lock mounting system enables front-side installation without front screws, simplifying cable management.
