Fanless AirJet cooler experiment boosts MacBook Air to match MacBook Pro's performance

Engineers from Frore Systems have integrated the company's innovative solid-state AirJet cooling system, which provides impressive cooling capabilities despite a lack of moving parts, into an M2-based Apple MacBook Air. With proper cooling, the relatively inexpensive laptop matched the performance of a more expensive MacBook Pro based on the same processor.

The lack of a fan is probably one of the main advantages of Apple's MacBook Air over its more performant siblings, but it also puts the laptop at a disadvantage. Fanless cooling doesn't have moving parts (which is a plus), but it also cannot properly cool down Apple's M1 or M2 processor under high loads, which is why a 13-inch MacBook Air powered by M1 or M2 system-on-chip is slower than 13-inch MacBook Pro based on the same SoC. However, making a MacBook Air run as fast as a 13-inch MacBook Pro is now possible.

    Since the Airjet still needs to move air through itself to work, those passages must be very small, doesn't seem like it would take much dust to block it..I wonder how easy it is to blow it out?

    apple's always been form over function.

    They could of easily made them run cool just choose not to.

    The product can sit directly on a cpu so it moves air through itself, practically on top of the cpu/chip. The inlet and outlet are so small and the pressure is so high that dust doesn't build up, and the power usage and noise are lower. It's very cool tech that uses an odd vibrating film system to produce the airflow.

    It's basically a fan without a heat pipe or sink, instead directly attached to the cpu.

    Edit: FYI in this case they didn't do any of that, so this is a very generic tacked on just test of the thing. In a system designed for it the airjet could be directly mounted or mounted on top of a heatsink if you want to use multiples. The direct mount sounds much more interesting to me.

    How much power do these fans take however?

    Mini is ~1W consumed/~5W dissipated and the Pro is ~1.75W consumed/~10W dissipated (this is per unit). This test was with 3x Minis so ~3W of power consumption. I'm not sure how this compares to the fan in the MBP as I couldn't find any specs, but Steam Deck fan as an example uses ~2.5W max.
