Gamdias Chione E4-420 Liquid Cooler - Black / Hydraulic PWM Fans / Dual Infinite Mirror / Real-time Digital Display / Patented PWM Pump / Motherboard Sync ARGB / CHIONE E4-420

The Gamdias Chione E4-420 Liquid Cooling System uses advanced hydraulic PWM fans and a patented PWM pump to hold a CPU in safe operating temperatures through long gaming marathons. Its substantial radiator size is what gives it that headroom. A dual infinity mirror surrounds a real-time digital display of system performance, and ARGB lighting synchronises with the motherboard.

The CHIONE E4-420 Series is available in black and white. Cooling comes from a patented PWM pump running at 4600 RPM alongside three 140mm ARGB PWM fans, backed by a digital display set within dual infinity mirrors showing real-time CPU temperature and fan speed. The 140mm fan size lets the cooler move air at lower rotational speeds than 120mm equivalents.

The digital display sits inside the water block and reports real-time CPU temperature and fan speed, so system health is checked by looking at the machine rather than opening software. Two RGB infinity mirrors surround the display and give it depth behind a side panel. On a large cooler the block is the visual centre of the build, so what it shows matters twice over.

The CHIONE E4-420 WH places its patented 4600 RPM PWM pump on the side of the radiator, which minimises bracket vibration and extends the unit's lifespan while still delivering elite performance. Its detachable chamber simplifies fan installation, a real advantage on a radiator this size where working room is scarce once the cooler is in the case.

The PWM fans operate between 450 and 1800 RPM and push airflow up to 100.28 CFM with superior static air pressure. The low 450 RPM end of that range is what keeps the system quiet during light use, while the top end is there for sustained load. Hydraulic bearing fans handle the work, pairing PWM control with customisable RGB lighting.

Cabling on the Chione E4-420 runs through a hidden routing mechanism designed into the cooler, keeping fan and lighting leads off the visible side of the build. A 420mm radiator carries a lot of cables by definition, so having them routed at the source removes the largest single cable-management job in the assembly.

Thirty pre-set lighting effects are switchable through the provided switch connector or a dedicated case LED button, so lighting is controllable without installing anything. Connecting the cooler to a motherboard with a 5V 3-Pin addressable RGB header hands control over to the board for synchronised, personalised effects across every component in the system.

The CHIONE E4-420 WH uses ZEUS CAST software for real-time monitoring, letting you choose what the block displays. Modes include CPU temperature, temperature alerts and fan speed RPM data, so the display can run as a live readout or as a threshold warning. Alerts are the mode worth setting up, because they catch a cooling problem before performance drops.

The CHIONE E4 Series installs on both Intel and AMD platforms, with LGA 1700 and AM5 sockets covered by the universal mounting kits supplied in the box. Socket support decides whether a cooler is even usable on a given board, so having current Intel and AMD mounts included means the installation does not stall waiting on a separate bracket.
