Product Details
Take your thermal management and custom rig aesthetics to the extreme with the GAMDIAS CHIONE M4-420 AIO Liquid CPU Cooler. Engineered specifically to handle the high heat loads of top-tier Intel and AMD desktop processors, this 420mm liquid cooler pairs an oversized 32mm thick radiator with a patented low-vibration in-line PWM pump.
At the center of your system, the CHIONE M4 features a 360-degree rotatable water block housing a 2.1-inch real-time LCD display. Paired with the dedicated CHIONE CAST LITE software, it displays vital system statistics—including real-time CPU temperatures, pump RPMs, and fan speeds—so you can monitor performance at a single glance.
Key Features
Real-Time 2.1" LCD Display
Keep track of your system hardware status instantly. The 2.1" LCD screen displays live CPU temperatures, fan RPM, and pump speed scales. Temperature units (°C/°F) and layout settings are easily customizable using CHIONE CAST LITE software.
360° Rotatable Water Block
Orient your tubing and display exactly how you want. The water block can be rotated 360 degrees, allowing clean alignment and optimal display visibility regardless of motherboard orientation or tube routing.
High-Density 32mm Radiator Architecture
Built with a 25% to 40% increase in fin thickness and density compared to standard liquid coolers, the 32mm thick aluminum radiator provides a significantly larger surface area to dissipate thermal energy quickly.
Patented In-Line PWM Pump (Up to 5400 RPM)
By integrating the high-speed PWM pump directly in-line with the tubing, the CHIONE M4 delivers strong liquid flow while reducing direct vibration on the CPU socket, ensuring silent operation and extended component lifespan.
High-Performance 140mm ARGB PWM Fans
Three 140mm hydraulic bearing fans deliver massive airflow (up to 90 CFM) while keeping noise levels low (11-29 dBA). Equipped with standard 3-pin 5V ARGB connectors, lighting can be easily synced through major motherboard ARGB software.
Durable Nylon-Braided Teflon Tubing
Features 450mm extended Teflon tubing wrapped in flexible nylon-braided sleeves. The extra length accommodates mounting in large full-tower dual-chamber chassis with zero tube kinks or fluid evaporation concerns.
