Apple MacBook Air shows performance upgrade with silent AirJet cooling

Back in December 2022, Frore Systems announced the AirJet and AirJet Pro, an innovative cooling system that transports air out of the case using almost silent ultrasonic vibrations instead of conventional fans. AirJet Pro is designed to cool processors with a power loss of up to 28 watts.

After the demonstrations of AirJet in a 64 TB SSD and a mini PC, the manufacturer has now finally demonstrated the cooling system in a laptop, as reported by PCWorld and The Verge. Specifically, Frore Systems packs three AirJet Minis into a 15-inch MacBook Air. This means the Apple M2 should theoretically achieve similar performance values in the thin notebook without a fan as in the 13-inch MacBook Pro, in which Apple installs a fan. As benchmark tests show, the cooling system makes a noticeable difference: the frame rate in Shadow of the Tomb Raider drops to 22 fps without cooling, but with AirJet Mini the MacBook Air achieves 27 fps under continuous load.

In Cinebench R23, the multi-thread performance increases by 4.7%, while the notebook remains practically silent, unlike the 13-inch MacBook Pro, whose fans can get up to 49 dB loud under continuous load, even if 35 dB is rarely exceeded in practice. The MacBook Air still remains 11.5 millimeters thin with the AirJet Mini, but Frore Systems had to remove the speakers and the WLAN antenna to make room for the cooling system. Hence, if Apple were to implement such a system, the internal layout of the MacBook Air would have to be be adjusted.
