We’ve reached a point where managing heat isn’t just a technical detail, it’s a core business decision. Cooling today is about economics, sustainability, and survival in a world where AI workloads are scaling faster than the infrastructure designed to support them.

Immersion cooling often comes up in these conversations and it works incredibly well – in the right places, for the right reasons.

Where immersion shines

Immersion cooling isn’t a silver bullet, but it solves some specific, ever-growing problems that traditional air and even direct liquid cooling can’t always handle alone.

When we talk about raw performance, immersion helps keep silicon running at stable temperatures, no matter how intense the workload. That consistency matters not just for peak performance, but for predictable, reliable throughput over time.

Then there’s performance per watt, which is where immersion really starts to pull ahead. When you remove the overhead of chillers, CRAC units, and complex airflow management, the entire system becomes leaner.

Less energy wasted on fans and air handling means more power devoted to actual compute, all while consuming zero water.

As to the cost, it depends on what you’re measuring. Immersion offers significant long-term advantages, though it may require a slightly higher initial investment.

But if you widen the lens to consider the total cost of ownership – including energy, space, service routines, and hardware longevity, that’s when immersion proves to be the more efficient and cost effective choice.

Not every rack has to look like it belongs in a hyperscaler’s data center, but for HPC and AI organizations pushing the limits of what a traditional rack can do, immersion offers a path to squeeze more out of everything. That includes CPU compute, flash storage, GPU all fit into less space with increased performance, reliability and scalability.

There’s also operational simplicity. With immersion, you remove moving parts like fans and unnecessary components. It’s quieter, simpler and more reliable – issues usually caused by dust, vibration, or environmental factors.

Hardware refresh cycles and future-proofing

Running hardware cooler and more consistently is extending the lifespan of the servers. In practice, we have gathered more than six years of data resulting in lower failure rates.

Looking ahead, future-proofing is a major consideration. As GPUs and AI accelerators evolve, power densities are only going to increase. Organizations who adopt immersion today aren’t just solving current needs, they’re buying for the future.

Can different cooling methods coexist?

Absolutely. Direct Liquid Cooling (DLC) and immersion cooling can, and likely will, coexist in large-scale AI infrastructure.

Immersion is a strong fit for homogenous, high-density deployments that aim to maximize compute density and deliver stronger long-term ROI.

DLC makes sense for more complex infrastructure such as the Nvidia GB200-300. Managing mixed environments means thinking about how to balance immersion tanks, cold plates, and air cooled legacy gear in the same footprint.

Retrofitting without downtime

One of the biggest concerns we hear from operators is: “How do I retrofit my air-cooled infrastructure without risking downtime?” Some of the real-world challenges we’ve seen include:

• Physical space constraints in legacy data centers
• Power and plumbing not designed for liquid systems
• Warranty concerns for hardware in non-standard environments
• The learning curve for operational teams who’ve only worked with air

And yet, there are solutions emerging. Modular immersion tanks, for example, allow operators to convert specific workloads to immersion without overhauling an entire data hall. Colocation providers are starting to build immersion-ready suites. Hardware manufacturers are partnering with cooling vendors to ensure certification and warranty support.

Will immersion become the default?

For immersion to become mainstream, we need more buy-in from the entire ecosystem. That includes GPU and chip manufacturers building for immersion from the start, not as an afterthought. It means developing global standards and certifications so operators can deploy immersion with confidence.

We currently support three-year warranties for hardware in immersion, but the broader industry needs to align on this if adoption is going to scale.

Whether it’s building infrastructure, selling solutions, or supporting customers, we help people figure out what makes sense for their workloads, their budgets, and their long-term goals.

Eventually, cooling isn’t just about lowering temperatures. It’s about keeping businesses running smarter, longer, and more sustainably.
