Lenovo's AirJet-Powered Concept Laptop Ditches Fans for a Slimmer, Quieter Design

Lenovo unveiled a concept laptop at IFA Berlin 2026 that uses Frore Systems' AirJet modules to cool the processor without traditional fans. The system generates high-pressure air streams to dissipate heat, enabling a chassis just 10 millimeters thick and weighing 1.8 pounds. Lenovo says the technology could lead to larger batteries and quieter operation in future high-performance laptops.

The AirJet modules draw ambient air from inside the chassis and accelerate it to roughly 124 miles per hour, generating pressure that disrupts the thermal boundary layer on the processor's copper heat spreader. This allows heat to escape through the rear without the bulky vent arrays typical of conventional laptops. Lenovo's implementation embeds four modules along the motherboard's top edge, and the company claims the system matches traditional fans in power consumption while resisting debris and water.

The concept's 20-watt thermal ceiling suggests it targets ultraportables rather than gaming machines, though Frore's higher-capacity AirJet Pro could extend the approach. Lenovo emphasized the sample's stability and maturity, and the company's history of
