Google, TCS, and the physics of air-cooling a large data centre | Explained
Google and Tata Consultancy Services examined the feasibility of cooling a one‑gigawatt data centre using only air. Their analysis shows that pure air‑cooling would require massive airflow and would significantly reduce performance and energy efficiency, making it largely impractical. By contrast, liquid‑cooling systems involve higher initial capital outlay but deliver better thermal management and lower operating costs.
