NVIDIA GB200 & GB300 Liquid Cooling Kit: Production-Ready Thermal Management for AI Servers

Figure 1 – NVIDIA GB200 and GB300 cooling unit architecture: cold plates, manifolds, inlet/outlet, and quick-disconnect couplings.

As AI computing power continues to increase, thermal management for NVIDIA GB200 and GB300 platforms has become a critical challenge for system designers and data center engineers. Higher power density means heat can no longer be handled by air cooling alone — and every component in the liquid cooling loop must be engineered, validated, and delivered as a matched system.

NVIDIA’s GB300 NVL72, for example, is a rack-scale, fully liquid-cooled architecture that integrates 72 Blackwell Ultra GPUs and 36 Grace CPUs into a single platform. To help customers shorten development cycles, ALVC has launched standardized liquid cooling kits for the NVIDIA GB200 and GB300 platforms.

Why GB200 / GB300 Liquid Cooling Kits Matter

Developing a liquid cooling solution from scratch is slow and risky: each component must be designed, prototyped, tested, and integrated — often over many months. A standardized, production-ready kit removes that burden. The complete cooling kit includes:

• 💧 GPU cold plates
• 💧 CPU cold plates
• 💧 Coolant manifold
• 💧 Inlet & outlet water tubes
• 💧 Quick disconnect couplings (QDCs)

Built for GB200 and GB300 Platforms

Our GB200 and GB300 cooling kits are tailored to each platform’s cooling architecture. As shown in Figure 1, the GB300 cooling unit scales up with additional cold plates and manifolds compared with GB200 — matching the higher thermal load of Blackwell Ultra systems while keeping a consistent, validated design approach across the two generations.

Because the kits are standardized, all components are matched and validated together, eliminating the compatibility headaches that come from mixing components from different suppliers.

Already in Mass Production

Unlike developing a liquid cooling system from scratch, our standard GB200 / GB300 cooling kits are already validated for production, helping customers significantly reduce:

• ⏱️ R&D and testing time
• 💰 Development and validation costs
• 🔄 Repeated design iterations
• 📦 Supply chain complexity

Ready to Install & Use

The standardized kit allows customers to move directly to system integration and testing, without spending months developing every thermal component individually. From prototype validation to volume deployment, the path to a cooled, running AI server is dramatically shorter.

Prototype & Small-Quantity Orders Supported

Whether you need a few sets for prototype development, engineering validation, or initial testing — or larger quantities for production — we can support your requirements with the same validated kit design at any stage of your project.

Who Should Use These Kits

These kits are ideal for teams working on:

• NVIDIA GB200 / GB300 liquid cooling
• AI servers and GPU clusters
• Data center thermal management
• High-performance computing (HPC) systems

If you are working on NVIDIA GB200 / GB300 liquid cooling, AI servers, data center thermal management, GPU cooling, or high-performance computing (HPC), contact us for technical specs, samples, or a quote. Looking for a ready-to-use GB200 / GB300 cooling solution? Let’s discuss your requirements.

GB200 / GB300 Liquid Cooling Kit FAQs

What does the ALVC GB200 / GB300 liquid cooling kit include?

Each kit includes GPU cold plates, CPU cold plates, a coolant manifold, inlet & outlet water tubes, and quick disconnect couplings (QDCs) — a complete liquid cooling loop designed for the target platform.

What is the difference between the GB200 and GB300 kits?

The GB300 cooling unit scales up the cooling architecture with additional cold plates and manifolds to handle the higher thermal load of Blackwell Ultra systems, while both kits follow the same validated, standardized design approach.

Are the kits mass-production ready?

Yes. The GB200 and GB300 kits are already validated for production, helping customers significantly reduce R&D time, validation costs, repeated iterations and supply chain complexity.

Do you support prototypes and small quantities?

Yes. We support prototype development, engineering validation, initial testing, and larger production quantities with the same validated kit design.

Can ALVC customize the cooling kit?

We can adapt the standardized kits to your system requirements, and we also develop customized liquid cold plates and manifolds for battery, energy storage and power-electronics applications.
