Since the MacBook Air doesn’t have a fan for the SoC, its performance will throttle down during processor-intensive work to maintain a proper operating temperature. The M2 13-inch MacBook Pro, on the other hand, has a fan that expels excessive heat so the chip can keep chugging along.<\/p>\n

The AirJet is what Frore calls a “solid-state active cooling chip” that measures 27.5 by 41.5 by 2.8 mm, a lot smaller and thinner than a typical computer fan. It’s so thin that Frore was able to take an M2 15-inch MacBook Air and fit a set of AirJet chips inside the laptop. AirJet can keep the MacBook Air temperature at a proper level so the chip doesn’t have to throttle down. Using the Cinebench R23 benchmark, an off-the-shelf M2 MacBook Air was 7 percent slower than the M2 MacBook Pro. But the modified M2 MacBook Air with an AirJet setup matched the Cinebench score of the MacBook Pro.<\/p>\n<\/blockquote>\n
