Solid-state micro-cooling targets data center hotspots
Data Center Knowledge: Where Solid-State Micro-Cooling Fits in Data Centers
Solid-state micro-cooling could help data centers reduce hotspots in SSDs and other subsystems that liquid cooling and system fans don't fully reach.
Get smart on it
Solid-state micro-cooling is a technology that uses silicon chips to generate directed airflow through tiny channels, without rotating blades or bearings. It addresses a gap in current data center cooling systems: while liquid cooling focuses on high-power components like CPUs and GPUs, other heat-producing parts such as SSDs and memory can develop localized hotspots that reduce performance and reliability. The technology is designed to be embedded inside subsystems where traditional fans and cold plates cannot effectively reach, serving as a complement to existing rack and server-level cooling rather than a replacement. For mainstream data center processors, liquid-based micro-channels may eventually prove more effective than air-based cooling due to power density constraints, though air-based micro-cooling is seen as more viable for edge AI systems with lower thermal envelopes and tighter space constraints.

Data center backlash is uniting America
If there's one issue that seems to activate all kinds of voters in 2026, it's data centers. The rapid buildout of these massive server storage facilities - and the infrastructure construction and expenses that come with them - has sparked local opposition in communities across the country and become a major issue in many congressional and gubernatorial campaigns. At the same time, tech money has been pouring into many of these races. Leading the Future, a super PAC backed by ve
