Bykski Durable 4x80mm 2U Server AIO Liquid CPU Cooler For ARM S5000C 64 - Continuous Usage

This Bykski Durable 4x80mm Server AIO Liquid CPU Cooler is purpose-built for ARM S5000C 64 platforms, delivering reliable thermal performance for continuous, 24/7 operation. The compact 4x80mm radiator paired with a high-efficiency pump and sealed loop design ensures stable CPU temperatures under sustained, high-core workloads typical of server and workstation environments. Its robust construction and low-maintenance AIO architecture make it ideal for dense racks or small-form server chassis where space and airflow are constrained.
A high-flow microfin waterblock maximizes heat transfer from large surfaces, while the 4x80mm radiator optimizes airflow in front-to-back server layouts. The closed-loop design ships pre-filled and pre-bled for straightforward installation and dependable operation, minimizing downtime and service intervals.
