Lenovo has demonstrated a concept laptop that replaces conventional fans and heat sinks with tiny solid-state cooling chips. Called AeroBlade, the 14-inch laptop uses four AirJet Mini chips developed by Frore Systems to remove heat while keeping the machine exceptionally thin, light, and quiet, tells Live Science.
Each AirJet Mini measures 41.5 × 27 × 2.65 millimeters and weighs just 9 grams. Instead of rotating fan blades, the chip contains tiny membranes that vibrate at ultrasonic frequencies. These vibrations generate 2,000 pascals of back pressure, forcing ambient air through microscopic internal jets at about 200 kilometers per hour. The air flows across a copper base layer, carries heat away from the CPU and GPU, and exits through vents near the laptop’s rear hinge.
Eliminating bulky cooling components helps AeroBlade measure less than 10 millimeters thick and weigh only 830 grams. By comparison, similarly sized laptops can measure around 12 millimeters at their thinnest, while lightweight 14-inch models typically weigh between 1 and 1.3 kilograms.
The technology could become particularly useful as manufacturers bring more demanding AI workloads directly onto laptops. Running large language models and AI agents locally requires powerful GPUs that generate substantial heat. Conventional fans can manage these thermal loads but add noise and occupy valuable internal space. Passive heat sinks avoid fan noise but can lead to performance throttling when processors become too hot.
Frore says each AirJet Mini can remove 7.5 watts of heat while producing only 21 decibels of noise at peak power. Four chips provide about 30 watts of cooling capacity, comparable with conventional laptop cooling systems. Their back pressure is also roughly 10 times that of typical laptop fans.
AeroBlade is the first fully operational laptop to integrate AirJet technology. However, it remains a concept, and Lenovo has not announced when commercial laptops using the cooling system might become available.
