New laptop ditches noisy fans and heat sinks for tiny 'cooling chips' — it's much thinner and lighter than you'd expect

Lenovo has introduced a concept laptop called AeroBlade that utilizes high-speed air to cool its processor, instead of traditional fans or heat sinks. This innovative cooling system is powered by a tiny computer chip that is small enough to fit between your fingers. The AeroBlade features four low-power cooling chips, which are solid-state and active, meaning they have no moving parts and actively use a cooling mechanism to create back pressure, forcing ambient air through tiny internal jets onto a copper base layer at high speeds.

These chips contain tiny membranes that vibrate at ultrasonic frequencies to expel hot air from the laptop's central processing unit and graphics processing units, before being expelled from vents at the rear hinge. Lenovo unveiled the AeroBlade at Lenovo Innovation World 26 in Berlin, held from September 3 to 8, 2026. The laptop is much thinner and lighter than similar devices, measuring less than 0.39 inches thick and weighing only 1.8 pounds.

Compared to other laptops with 14-inch screens, which are typically considered light if they weigh between 2.2 to 2.86 pounds, the AeroBlade stands out as a rare example of a lightweight laptop. Lenovo and Frore Systems, the companies behind the technology, aim to use this cooling method to accommodate the growing demand for powerful on-device artificial intelligence in future laptops.
