The Deepcool SPARTACUS 420 RGB is a 420mm liquid CPU cooler designed to deliver premium thermal performance for demanding gaming rigs and workstation builds. With a large 420mm aluminum radiator, it provides powerful heat dissipation to help keep high-end processors under control during long rendering sessions, intensive multitasking, and sustained gaming workloads. If you want a cooler that balances strong cooling capacity with modern aesthetics, this model’s Addressable RGB lighting and motherboard synchronization support make it a practical choice for clean, customizable builds.
At the heart of the SPARTACUS 420 is its 420mm aluminum radiator, engineered for efficient heat transfer. The included fans are rated for an airflow of 112.5 CFM and an air pressure of up to 4.15 mmAq, which together support better airflow performance inside larger PC cases. This combination is especially helpful when your system has multiple heat sources—such as a high-TDP CPU paired with a powerful graphics card—because it helps maintain lower CPU temperatures and more consistent performance under load.
The cooler comes with three 140mm PWM fans that support automatic speed control via a 4-pin PWM connector. Fan speeds range from 500 to 2000 RPM, allowing the system to ramp up cooling when needed and reduce fan activity during lighter workloads. A key advantage is the 0 RPM mode during low workloads, which can significantly improve silent operation by stopping the fans when cooling demand is minimal—useful for everyday tasks, office work, and late-night gaming sessions where noise matters.
Noise levels are specified up to 32.89 dB(A), making the SPARTACUS 420 a strong option for users who want effective cooling without excessive sound. The fans use hydro bearing technology, which is built for long-lasting durability and smooth performance over time. For buyers planning to keep their PC for years, hydro bearing fans are a sensible match because they are designed to maintain consistent operation while reducing the likelihood of performance degradation that can occur with less robust bearing designs.
Efficient coolant circulation is supported by a pump operating between 2500 and 3400 RPM. This pump range helps ensure reliable thermal transfer from the CPU to the radiator, which is important for maintaining stable temperatures during heavy workloads. Compared to simpler cooling setups, a liquid cooler like this typically provides better heat management for high-performance processors, especially when paired with a case that supports a 420mm radiator installation.
The SPARTACUS 420 RGB features Addressable RGB lighting that creates vibrant, customizable effects. Lighting can be synced through the 3-pin 5V ARGB connector, making it easier to coordinate your cooler’s visuals with compatible motherboard lighting ecosystems. This is ideal for users building a themed setup—such as a clean white build, a dark minimalist setup, or a fully RGB-accented gaming station—while keeping cable management and control straightforward.
The cooler includes 465mm tubing, offering flexible installation options inside large PC cases. This extra length can help route lines more comfortably, reduce strain during mounting, and support cleaner internal cable management. Before purchase, ensure your case supports a 420mm radiator layout and that you have appropriate clearance for the radiator and fan stack.
Deepcool includes a 1-year warranty for product support and reliability. For customers in Bangladesh, the cooler is available through Tech Land BD, with authentic product support and trusted warranty service, along with competitive pricing and fast delivery across the country.
