That's liquid cooling, a cooling technology used in data centers which helps to improve power and cost efficiency. "As air cooling is approaching the limit of its cooling capacity, the importance of liquid cooling is getting increasingly more pronounced … liquid cooling [is] becoming a must-have for GB200," said the bank. Nomura estimates the liquid cooling penetration rate in Nvidia's AI servers is set to rise from 8% in 2024 to 43% in 2025, and 47% in 2026. Liquid cooling systems are the solution to "power shortage pressures" in data centers, Morgan Stanley said in a previous report . Against that backdrop, Jefferies is bullish on four Asian stocks it says will be "key beneficiaries" of the liquid cooling trend.
