Overview
This liquid-cooled HGX A100 node sustains full eight-GPU SXM4 80GB performance with direct-to-chip cooling for dense, thermally-constrained data centers. Nexus Compute specifies, configures, burns-in, and warranty-backs the system through authorized channels for continuous training duty.
Who This Solution Is For
Business Benefits
Sustained peak performance
Direct-to-chip liquid cooling holds clocks under continuous load, avoiding the throttling air cooling can incur.
Higher rack density
Liquid cooling consolidates more GPU compute per rack while controlling acoustics and hot-aisle heat.
Improved power efficiency
Lower cooling overhead and reduced fan power improve total facility energy efficiency at scale.
Typical Business Use Cases
Continuous foundation-model training runs
High-density GPU rack consolidation
Sustained HPC and simulation campaigns
Thermally-constrained data-center deployments

Frequently Asked Questions
What cooling infrastructure does this require?
It uses a direct-to-chip liquid loop and connects to a coolant distribution unit or facility water; we confirm CDU, flow, and rack requirements during specification.
How does it differ from the air-cooled HGX node?
Both use the same 8-GPU SXM4 80GB baseboard, but liquid cooling sustains higher clocks under continuous load and enables denser, quieter racks.
Is liquid cooling worth it for our workloads?
If you run GPUs near full load for long periods or need high rack density, liquid cooling reduces throttling and cooling overhead; we help weigh the trade-off.
