AI data center boom lifts Weltrend fan-control chip sales 64%

Weltrend's 64% surge in fan-control chip sales reflects the deepening reliance of global AI data centers on advanced thermal management solutions. Technologically, this growth fuels demand for upstream MCUs and sensors, while pushing downstream server vendors to optimize cooling architectures. From a compliance standpoint, tightening U.S. export controls are likely to increase operational costs and force supply chain reconfigurations, especially for critical materials. Competitively, TSMC, MediaTek, and others may accelerate investments in AI-related cooling chips to capture market share in both edge and data center segments. Over the next 12–24 months, as AI compute clusters expand, cooling systems will become a core bottleneck in infrastructure development, driving sustained growth in related chips. Firms with localized manufacturing capabilities will gain strategic advantages in this evolving landscape.
