Quiet, ultrathin AirJet solid state active cooling chips could replace fans

I would have two laptops side by side, with motherboards exposed running some benchmark, and prove that my cooling solution could move more heat, be quieter, be smaller, or some combination of those things.
The fact it is demo'ed just as a fan is in my mind suspicious.
Perhaps a mostly-sealed case with liquid cooling solution where the radiator is outside of the case would be more optimum.

No, the claim is 200 kph. He also said it's about 120 miles per hour.
Common modern usage of "solid state" in electronics seems to be synoymous with "no moving parts", not solid as opposed to liquid/gas.
Vibration is kind of an edge case though, so I'm not really sure. There's an expectation that solid state components don't usually fail mechanically or need maintenance in that department. I wonder what the lifetime is for this type of vibrating component?
I like a nice big chunk of metal! it ain't sexy, but its quiet and reliable.
All cooling is just moving heat from one place to another. There's no other way to cool anything.
With Intel parts you can run them with no cooler, they'll just throttle to maintain 100 °C by default (exactly like in laptops). Not every motherboard allows this though, some will start beeping angrily when PROCHOT is asserted or reset.
With Ryzens it depends, the chiplet ones can't do it, because the IOD power consumption exceeds what the IHS can dissipate without a cooler, so no matter what the CPU power management does, it will always eventually shut off. If you're in OC mode, it will do so at 115 °C. The APUs can probably do it, they'll probably be faster than Intel because they're more efficient.
CPUs without an IHS just explode though.
Of course, who knows if all these things are true, but this is a shallow dismissal.
So both will happily stay at CPU melting point.
They say that - "The Mini can dissipate up to 5 Watts of heat, while the larger Pro models can dissipate up to 10 Watts." which is definitely not enough to run performance laptops on sustained load.
>"but this is a shallow dismissal."
See the above. I think it is not dismissal that is shallow.
As for what they plan to have in the future - it will be believable when they show how they're going to achieve it
Traditional fans and heatsinks have no problem dissipating 100's of watts. Wake me up when this contraption will do the same.
>"high velocity air hitting the cooling surface vertically at high speed is much more efficient at removing heat than low speed blowers"
Except that traditional blowers operate on immense surface are hence dwarf the efficiency of this gizmo. Anyways we do not have to agree. The future will tell. Wake me up in a year.
