Cooling and thermal management
High-density AI hardware generates heat that air cooling can no longer remove efficiently. Liquid cooling has moved from niche to mainstream for frontier AI deployments.
Key facts
- Direct-to-chip liquid cooling and immersion cooling are increasingly standard for dense AI racks.
- Cooling efficiency directly affects energy use and therefore the operating cost of AI.
- Retrofitting existing air-cooled data centers for liquid cooling is costly and slow.
- Thermal limits, not just electrical ones, now influence how much compute can be packed into a given space.
Where it bottlenecks
Liquid-cooling supply chains (cold plates, coolant distribution, manifolds) are young and a practical constraint on rapid build-out.
