So that the reduced thickness of the MacBook Air (both the 13 and 15 inch) was reached, it was necessary to remove the laptop’s fan, unlike the Pro models, as well as desktop Macs.
Therefore, even compared to machines that have the same processor, the MacBook Air has a slightly lower performance in times of greater demand, causing a decrease in processor power so that the laptop’s temperature does not rise too much.
With that in mind, the Frore Systems created the AirJet, a device capable of dissipating heat from the Mac, making a MacBook Air with an M2 processor have performance equivalent to that of the 13″ Pro model with the same chip (which has a fan). However, creation is not a fan: it works through vibrations in membranes that create pressure so that hot air leaves the computer, using the speakers as exhaust fans and modifying the structure of the machine near the hinges.
The device is what the company called solid state active cooling chip. An important difference compared to a conventional fan is the small thickness (2.8 mm) as well as the compact size (27.5×41.5 mm). The device also makes less noise than the MacBook Pro’s fan.
With AirJet installed, a 15″ MacBook Air achieved basically the same result as a MacBook Pro with an M2 chip in Cinebench R23. Without the device, the number was 7% smaller (8.238 points once morest 8.720), due to the Mac’s performance and temperature control. With the additional cooling, performance was able to maintain its maximum level even when performing a heavier task, as well as maintaining it for longer when multitasking.
The bad news is that the AirJet is not — yet, at least — a product produced on a large scale and aimed at the end consumer. It is not being sold and, even if it were, the task of inserting it into the computer would not be the simplest, considering the difficulty of modifying the inside of an Apple computer.
In any case, Frore stated that Apple’s adoption of this technology, including in other Mac models, might free up internal space — since the AirJet is much smaller than a fan —, allowing, for example, the increase in battery capacity . More tests would be necessary, however, to prove the viability of this hypothesis.
As highlighted by The Verge, there is a concern regarding power consumption: three AirJets, for example, consumed more than 5W of power from the MacBook’s USB-C port. The company, however, said that a mini version of the chip is already in mass production and has been tested in webcams, lamps and other devices.
