Overview
This direct-liquid-cooled build of the Supermicro 8U HGX H100 platform routes coolant over all eight SXM5 GPUs and the NVSwitches to sustain peak clocks while reducing data-center cooling power. Nexus Compute specifies the cooling loops and CDU integration, validates the system, and warranty-backs it through authorized Supermicro channels.
Who This Solution Is For
Business Benefits
Lower cooling power
Direct-to-chip liquid cooling can cut data-center cooling energy by up to roughly 40% versus air at equivalent density.
Sustained peak clocks
Liquid blocks hold GPU and NVSwitch temperatures down so the node maintains performance under continuous load.
Integrated and validated
We coordinate manifold, CDU, and leak-checked loop integration so the node arrives ready to commission.
Typical Business Use Cases
Continuous high-utilization model training
High-density GPU racks in constrained facilities
Sustainability-driven AI infrastructure builds
Liquid-cooled cluster nodes
Industry Applications
Technical Overview
The platform mounts the NVIDIA HGX H100 8-GPU SXM5 baseboard with four dual-GPU cold plates plus a liquid-cooled NVSwitch block across four coolant loops. Dual Intel Xeon Scalable CPUs and up to 8TB DDR5 sit in the 8U chassis with PCIe Gen5 fabric slots and Titanium redundant power.

Frequently Asked Questions
Do we need a CDU or facility water?
These nodes connect to a rack or row coolant distribution unit; we help specify the CDU and confirm whether facility water or a closed loop fits your site.
Why choose liquid over the air-cooled version?
Liquid cooling lowers cooling energy and sustains peak GPU clocks under continuous load, which matters most for dense racks and long training runs.
Is servicing more complex?
Loops are quick-disconnect and leak-checked before shipment; we document maintenance procedures so your team can service nodes safely.
