What is Server CPU/GPU Waterblock?

A server CPU/GPU waterblock is a specialized liquid cooling component used in data centers, AI clusters, and high-performance servers. It transfers heat directly from processors through a precision-machined copper or nickel-plated cold plate with microchannels that allow coolant to flow and carry heat away. It can also be applied to standard CPUs and GPUs in consumer systems.
 
Compared with consumer waterblocks, server-grade designs focus on 24/7 reliability, high thermal efficiency, and compatibility with dense rack environments, ensuring stable operation under heavy workloads while reducing overall energy consumption.
 
At Kingka Tech, we leverage decades of thermal management expertise and advanced CNC machining to deliver customized server waterblocks for enterprise applications, ensuring both high performance and long-term reliability.
