Chips to Replace Fans

Beyond fans: AirJet’s radical CPU cooling chips can double laptop performance

Solid State Active Cooling Could Revolutionize Thermals (16m21s video)

Supposedly appearing in some laptops by late 2023. The second generation of the product could be used in smartphones, some of which use fans.

    Because of the high back pressure, he said, the intake holes can be covered with an IP68 waterproof/dustproof material, allowing a laptop maker to prevent dust and other particles from coating the inside of a laptop.

    Is that "can" an euphemism for "must" here? Or can this stuff actually handle the dust/dirt levels in normal environments (note there are two "normals" depending on whether you include smokers or not)?

      It's a good question. Why aren't such materials used with normal fans, because they "suck"? Maybe the higher pressure created by these chips makes it more viable.

      If dust does get in, just call it planned obsolescence.

      Eliminating vents on the bottom does seem like a real benefit though.

        I asked a person I know who works on this sort of design and his reaction was equally skeptical. There is a lot of marketing fluff in that article and handwaving behind hypothetical statements or incomplete pictures. But one thing they pointed out is that according to their figures, that fan creates 1750 Pa at an unspecified location. To truly harness that pressure, it will have to be ducted or have a partition between the high side and low side. Either way, instead of static pressure against the enclosure it will feel a dynamic pressure with a distinct differential and flow. Furthermore, the natural flow in the case would be to come in at the seams, through the cooler, and out, which means that a ducted situation would basically pump the water into one of the most sensitive parts of the machine. This tech might accomplish what they are saying, but there are a lot of "ifs" and "coulds" to figure out first that this doesn't even begin to address.

          Hopefully, their claims will be tested by the end of 2023, if it comes to ultrabooks around then. But I don't think both Intel and AMD would be singing the praises of this company if they were full of hot air.

            Sure they would. Their incentive is to make their processors look fast. If the processor can run for longer while automatically overclocked, then it is faster with zero effort for the processor designers. What happens to the waste heat after it is conducted away isn't their problem. What happens if the initiative by AirJet fails isn't their problem. They've literally got nothing to lose and everything to gain by making their chips faster for the cost equivalent of a rounding error in their accounting.

      It's a "can" [youtube.com] which obviously translates to "should".

    Does this generate loud ultrasound?

    Chips will sit there in dead silence. No more clapping and cheering to reinforce your ego. Just one more example of machines replacing people.
