11 mm, 816 Grams: Lenovo Shows Off Fanless Laptop Concept

    “Lenovo” showcased its “Project AeroBlade” laptop concept, which operates without a conventional fan, at “IFA 2026.” Based on a “ThinkBook,” the model fits an active cooling system into a thinner and lighter chassis. Although the device resembles an ordinary business laptop, its main innovation is the cooling system inside. The company has not yet announced when the concept will go on sale.    The system, called “Active Flow,” uses 4 small “AirJet” modules developed by “Frore Systems” instead of conventional fans. These modules use ultrasonic vibrations to draw cool air into the chassis and expel hot air. Each module is just 2.7 mm thick and is approximately the size of a mobile processor. According to the manufacturer’s calculations, “AirJet” produces 10 times more suction pressure than a conventional laptop fan. This is the first demonstration of these modules in a working laptop.    The 14-inch concept is just 11 mm thick and weighs 1.8 pounds, or approximately 816 grams. “Lenovo” used 4 “AirJet” modules to perform the work typically done by 2 fans. Thanks to the powerful airflow, there is no need for air-intake openings on the bottom of the chassis. Air enters only through a narrow opening along the laptop’s rear edge and exits through the same area. As a result, the bottom panel looks completely smooth.    The “ThinkBook” on display ran on a 17 W “Intel Core Ultra 7 Lunar Lake” processor. The concept aims to enable more powerful processors to operate in thin and light laptops. Conventional fanless models require either a lower-power processor or limits on processor speed to reduce heat. “Active Flow,” however, creates active airflow inside the chassis while retaining the advantage of silent operation.    During the test, the “AirJet” modules could not be heard, and the vibrations they produced could not be felt. The lack of moving parts in the system could extend the device’s lifespan because conventional fans collect dust and can fail over time. “Lenovo” has not announced when a finished product will be released. “Frore Systems” has also not disclosed whether it is working with other manufacturers. The modules can be placed in different areas of the motherboard, but doing so requires redesigning the laptop’s internal layout.
