Inside JetCool's Dell PowerEdge XE7745 Cooling Server

Adding more compute without overwhelming power and cooling systems is a familiar challenge for data centre operators.

Demand for GPU-heavy workloads is on the rise, and these companies are looking beyond traditional air cooling to increase rack density while keeping existing facilities in service.

JetCool is aiming to address this with the launch of a liquid-cooled version of the Dell PowerEdge XE7745 server.

The company has packaged the server, liquid cooling, rack infrastructure and lifecycle services into a single deployment backed by one warranty, with the system delivered factory-tested and ready for installation.

It is designed to reduce the complexity that often comes with introducing liquid cooling, while providing a single point of accountability across deployment, commissioning and ongoing maintenance.

A packaged approach to liquid cooling

The liquid-cooled Dell PowerEdge XE7745 is built for AI, high performance computing (HPC) and GPU-accelerated workloads.

The platform supports dual fifth generation AMD EPYC processors alongside as many as eight NVIDIA RTX PRO 6000 Blackwell GPUs, creating a dense compute platform for demanding applications.

To manage the heat generated by those components, JetCool uses its SmartPlate direct-to-chip liquid cooling technology.

Instead of relying on air moving through the chassis, the system removes heat directly from the processor and GPU surfaces, allowing sustained workloads of up to 8kW per server.

According to JetCool, the cooling design reduces CPU temperatures by as much as 7% and GPU temperatures by up to 11%, helping systems maintain performance under heavy computational loads without thermal throttling.

The company also says the configuration cuts total server power consumption by as much as 30% by reducing fan speeds by up to 70% and fan power by as much as 50%.

Acoustic output is also lowered by up to 23dB, reducing perceived server noise by around 80%.

By moving heat away from the chips more efficiently, the system also frees rack-level cooling and power capacity.

That gives operators the opportunity to increase compute density within their existing data centre footprint rather than expanding into new facilities.

"Scaling next-generation AI demands a leap forward in compute density, but the real key to success is bringing that power online quickly, safely and efficiently," says Bernie Malouin, Founder of JetCool and Vice President at Flex.

"By delivering the Dell PowerEdge XE7745 as a fully integrated, liquid-cooled system backed by end-to-end services, we're taking the risk out of high-density deployments.

"We're giving operators a reliable path to get peak performance out of their hardware while keeping their existing facility running predictably."

Designed for existing facilities

One of the barriers to liquid cooling adoption is the work required to integrate new infrastructure into operational data centres.

JetCool says its system is designed to minimise that disruption through low-flow operation, enabling organisations to replace lower-density servers without requiring changes to existing facility water loops.

Customers receive physical racks, mounting hardware, coolant distribution units (CDUs), manifolds and fluid distribution equipment as part of a complete rack-level assembly. By shipping the platform as a factory-tested system, JetCool aims to shorten installation times and reduce deployment risk.

The company also combines commissioning, deployment support and ongoing maintenance into the same offering, with unified warranty coverage spanning both the server and the cooling environment.

Simplifying procurement and operations

Organisations are looking for integrated solutions, instead of following the fragmented process of assembling hardware, cooling systems and support contracts from multiple suppliers.

JetCool's offering brings together server hardware, liquid cooling, supporting infrastructure, lifecycle services and warranty coverage under a single contract.

This essentially means that one supplier is responsible for system configuration, delivery and ongoing support.

The solution is also backed by Flex's manufacturing, supply chain and global service capabilities, allowing deployments to be delivered consistently across multiple sites and regions.

By combining Dell's PowerEdge XE7745 platform with factory-integrated cooling and deployment services, JetCool is positioning the technology as an integrated operational upgrade, easing the process so that customers do not have to integrate themselves.
