Tired of your laptop's noisy fans? Technology for fanless cooling may soon make you at peace.

An innovative new cooling solution could lead to the demise of the laptop fan if it really is as efficient as its creators suggest. San Jose-based Frore Systems (opens in a new tab) has developed a revolutionary new "cooling chip" that could be implemented to provide excellent — and near-silent — cooling for everything from the best ultrabooks to the best VR headsets.

This is also not passive cooling; Despite the lack of fans, these chips (called "AirJet") provide active airflow by vibrating superthin membranes inside the chip at ultrasonic frequencies to generate air currents. A name is nothing if it is not appropriate.

This process provides cooling by drawing cooler air through small vents on the top surface of the chip and then flowing it through a narrow chamber on the bottom where it comes into contact with the heat dissipation plate. The heatsink absorbs heat from the cooled component (such as the copper heatpipes attached to most laptop processors) and dissipates it with an internal AirJet airflow, drawing warm exhaust air from one end of the chip.

A small step for laptop fans

Even the best laptops can have problems with fan drone under heavy load (aside from the iconic fanless MacBook Air, of course), and Frore System's solution is said to be able to eliminate the problem entirely.

The technology – which comes in two variants, the AirJet Mini and the larger but more powerful AirJet Pro – is said to significantly outperform conventional laptop fans thanks to massively increased air pressure generated by a small chamber inside the 2.8mm thick chip.

According to its creators, the AirJet operates at 21 dBA. This is quieter than a human whisper, approaching the lower layers of human hearing; for reference, the average laptop fan sits above 40 dBA, while normal speech sits around 65 dBA. The chip also only requires a small amount of power, just one Watt for the AirJet Mini.

Frore Systems also claims to have equipped a passively cooled Arm-based laptop with four AirJet Mini units and found that the processor could run at full turbo frequency without issue - while using the existing passive cooling system resulted in frequent drops to lower frequencies.

Frore System is currently working with Intel and its laptop partners to (hopefully) deliver a new AirJet-cooled laptop by the end of 2023, but don't get too excited; this is new technology, and CNX Software (opens in new tab) noted that Frore has previously said that this advanced technology will come with "competitive" pricing, so we can probably expect it to appear exclusively on high-end devices at first.
