Beyond air cooling

AI racks have outgrown air

AI racks have outgrown air

Today’s GPU servers pack more heat into each rack than fans and raised floors were designed to move. When cooling falls behind, hardware throttles and capacity sits unused.

Liquid carries heat away far more efficiently than air. ASpeed AI Power liquid cooling systems let AI racks run at the densities they were built for.

Why liquid cooling

More compute in the same footprint

More compute in the same footprint

More compute in the same footprint

Higher rack density

Support more compute in the same footprint.

Full performance

Keep GPUs below throttling temperatures under sustained load.

Lower cooling energy

Use less power for cooling than equivalent air systems, leaving more for compute.

Future-ready

Prepare your facility for next-generation hardware that requires liquid cooling.
