Tech journalists and YouTube reviewers who got their hands on the new M2 Macbook Air voiced concerns about the overheating machine. Part of the problem comes from the M2 MacBook Air lacking fans or heat pipes, despite housing the same powerful M2 chip as the Macbook Pro.

The Verge loved the new industrial design of the M2 MacBook Air but was concerned about the heat throttling performance. The publications review puts it this way: “[…] the M2 Air is noticeably slower than the MacBook Pro M2, which has a thicker chassis and a fan to help keep the chip cool under long-running heavy workloads, like a 30-minute Cinebench 23 multi-core benchmark.” The review also mentioned the throttling that occurs to “keep its speeds capped in an effort to keep temperatures manageable” and that the bottom of the laptop still got “considerably warm” during these tests.

Endgadget was overall impressed with the new MacBook Air but warned that thermal throttling can slow the computer during more intense workloads, saying, “All of my testing made it clear that the MacBook Air is just as fast as the 13-inch Pro for most tasks. It even hit the same 30 fps average in Shadow of the Tomb Raider‘s benchmark, which means the game would actually be playable on a crazy thin ultraportable. But you’ll have to live with a bit of slowdown if you’re doing more complex work, like video editing or 3D rendering.”

Reviewers overall were blown away by the redesigned MacBook Air, which brings it more in line with Apple’s new vision of hardware. The boxy, industrial design edges and the brilliant screen were praised a lot by reviewers. But every single reviewer mentioned thermal throttling issues.
