Valkyrie Jarn 360mm ARGB All-in-One CPU Cooler - Black (VK-AIOJR360B)

The Valkyrie Jarn 360 CPU Liquid Cooler is engineered for high-performance systems that demand maximum thermal headroom and bold ARGB styling. Designed to handle CPUs up to 300W TDP, this 360 mm all-in-one liquid cooler combines a reliable PWM-controlled pump, an extended aluminum radiator, and three high-airflow Valkyrie V12 A-RGB fans to deliver powerful and consistent cooling for demanding gaming and workstation builds.

At its core is a PWM-controlled pump operating between 8002400 RPM ±10% at 12V, ensuring responsive cooling performance while maintaining low noise levels. The pump housing measures 83 × 78.6 × 58 mm and is paired with 425 mm FEP tubing for flexible installation in larger cases. The tubing is reinforced with a corrugated braided sleeve for durability and a clean, premium appearance.

The 379 × 120 × 27 mm aluminum radiator provides increased surface area for improved heat dissipation, making it ideal for high-core-count CPUs and heavy workloads. It is equipped with three Valkyrie V12 A-RGB 120 mm fans operating between 8001850 RPM ±10%. Each fan delivers up to 75 CFM (127.42 m³/h) of airflow with 2.23 mmHO static pressure, ensuring strong airflow through dense radiator fins. Maximum noise levels are rated at 34 dBA, and Fluid Dynamic Bearings ensure long-term reliability and smooth operation.

The cooler connects via a standard 3-pin 5V A-RGB header for synchronized lighting control and 4-pin PWM connectors for precise pump and fan speed management.

Backed by a 5-year international warranty, the Valkyrie Jarn 360 delivers serious cooling capacity, modern lighting, and long-term reliability for performance-focused PC builds.
