Lenovo has introduced a concept laptop that replaces traditional fans with 'AirJet' cooling chips, allowing for a thinner and lighter design.

Lenovo debuted the AeroBlade concept laptop at Lenovo Innovation World '26 in Berlin on Sept. 3. The device utilizes four solid-state cooling chips developed by Frore Systems to manage heat, eliminating the need for conventional fans or heat sinks. This technology allows the laptop to maintain a slim profile while potentially supporting high-performance tasks like on-device artificial intelligence.

How the Cooling Technology Works

The laptop uses AirJet Mini chips, which contain membranes that vibrate at ultrasonic frequencies. This process creates 2,000 pascals of back pressure, forcing air through internal jets at speeds of approximately 124 miles per hour. This high-velocity airflow removes heat from the CPU and GPU before expelling it through rear vents. Each chip can remove 7.5 watts of heat, with the four-chip configuration totaling 30 watts of heat removal.

Design and Performance Specifications

The AeroBlade measures less than 0.39 inches thick and weighs 1.8 pounds. In comparison, standard 14-inch laptops typically weigh between 2.2 and 2.86 pounds. The cooling system operates at 21 decibels at peak power, which is described as being as quiet as a whisper. While the AirJet technology was previously used in a mini PC in 2023, the AeroBlade is the first fully operational laptop to feature it.

Future Implications for AI Laptops

Lenovo and Frore Systems suggest this cooling method could support future high-end laptops designed for local AI processing. Running large language models or AI agents locally requires significant power and cooling, which often leads to performance throttling in machines using passive heat sinks. The AeroBlade remains a concept model, and Lenovo has not announced a release date for production-ready versions.
