CTOnews.com, Nov. 28-Apple's 15-inch MacBook Air doesn't have a fan, but uses a passive radiator to derive heat from the M2 chip. If the notebook uses an active cooling scheme, can the performance be further improved? Frore Systems installed a unique solid-state active cooling system in this laptop and conducted a number of benchmark tests with impressive results.

Frore Systems is a $116 million startup whose flagship product is AirJet Mini, an almost silent cooling solution that uses piezoelectric cooling chips that Frore claims to outperform fans. Inside the AirJet is a tiny diaphragm that vibrates at ultrasonic frequency, sucking air into the air intake at the top of the AirJet and then ejecting it in the form of a high-speed pulsed jet through the bottom.

According to The Verge, the benchmark initially showed that the 15-inch MacBook Air with AirJet Mini was only slightly better than the standard MacBook Air, but as the test went on, the modified laptop began to take a big lead as the fanless MacBook Air turned on frequency reduction to lower the temperature. When using the Cinebench R23 test, the normal MacBook Air multicore score dropped sharply after a few repetitions-from 8775 for AirJet to 8380 without AirJet.

Despite its small size, the 2.8mm thick AirJet is difficult to fit into MacBook Air's thin fuselage. Frore had to remove 0.3mm from the lid of its laptop to create enough space for the airflow system and remove speakers, Wi-Fi antennas and internal keyboard connectors in the process. For most of us, buying a MacBook Pro with a fan is definitely a better choice.

CTOnews.com noted that another issue that was not addressed in the test was the impact of the system on battery life. Frore said that when the AirJet Mini chip is correctly integrated into the laptop, it only needs an extra 1 watt of power to run, and the system consumes only 0.1W or 0.2W of power when idle, and the AirJet Mini itself will only be turned on when needed.

Frore says AirJet Mini is already in mass production and is developing larger and smaller versions.
