High-performance 420 mm AIO cooler

The Glacier One 420D30 X2 is an all-in-one liquid CPU cooler built for gamers and PC enthusiasts who push high-end processors under sustained loads. It supports Intel LGA 115x, 1200, 1700 and 1851 sockets as well as AMD AM4 and AM5 platforms. A large copper base and fin array transfer heat into the 456 x 138.5 x 27 mm aluminum radiator. Three 140 mm D30 fans deliver up to 71.93 CFM each across a 250 to 1800 RPM range.

Interconnecting D30 fans and VRM-focused pump cover

The three D30-140 fans lock together into a single 420 mm frame so only one cable carries both D-RGB lighting and PWM signals, reducing cable clutter behind the motherboard tray. The Evolv X2 aluminum pump cover houses an integrated fan that directs airflow toward nearby VRM heatsinks and M.2 slots. Pump speed runs at 3100 RPM with a ceramic bearing rated at 20 dBA, while fan noise peaks at 29.5 dBA. Tubing uses CIIR rubber with black braided sleeves and measures 400 mm long with a 12.5 mm outside diameter.

Single-cable D-RGB and fan control

A unified cable links the pump, the integrated VRM fan and the three radiator fans, so lighting effects and speed curves are managed through one motherboard header or controller. The package includes mounting hardware for every listed Intel and AMD socket, thermal compound and the interconnect brackets that join the fans into the single frame. No additional software suite is required beyond standard motherboard RGB and fan utilities.
