Ventiva's ICE9 thermal management system uses the movement of ionized particles to generate airflow without any moving parts.

This looks like an amazing solution for cooling VR headsets.

I'd love to see this on full fan sizes too - 80mm to 140mm

Maybe soon we'll have some good ARM handheld, but it may work fine enough for x86.

My rog ally gets freaking hot, and is uncomfortable. Maybe a solution like this would do a better job.

Do you know what ionized air attracts? dust
Do you know what clogs these ionizers up? dust
Do you know what sensitive electronic devices don't like? ionized air.

There is a reason ionized air purifiers fell out of favor compared to good old filters.

It almost looks like a planar magnetic headphone driver. They move air to make sound, so maybe similar tech?

Ozone production too. From what I've read of their pre-release material, they have somehow figured out a way to prevent dust build up and ozone production. Too good to be true? Probably, but we will soon find out

I don't get it ... so they run a heat pipe from the processor to the ventiva thingy.

The Ventiva® active thermal management solution, ICE®, is a ground breaking advance over the previous cooling technologies used in electronic devices.

But they also recommend a standby fan for turbo mode?
So the 40w capacity is really twenty?
Seems ... marginal.

What about potential health concerns with that cooling device?
After all, it's based on ionization of air molecules. Is there proof that all ionized molecules get de-ionized before leaving the chassis of the laptop?

The level of ozone produced would be so small so as to be irrelevant. I doubt it's harmful levels even if you're sniffing it with your nose right on the exhaust.

Major retailers and brands still carry ionic air purifiers. These things are way larger and produce significantly more ionized air and ozone, yet they are still sold.

Major brands like Ionic Pro, and Honeywell Quietclean to name a few.

That's all nice and fine, but I would love to see some numerical evidence. The ionizing air purifiers have to follow rules and laws (e.g. 0.05 ppm ozone levels indoors), and usually, you don't sit 8 hours right in front of them.
An air-ionizer that is in your laptop that you sit in front of it for many hours a day (maybe at some 40 cm distance from the exhaust) and directly breathing the air that comes out of it, has the potential for some serious direct air pollution. That's why real-world testing trumps theory.
Just to be clear: I wish you are right and would be delighted to see this innovative cooling mechanism is entirely safe to use.
But you know the old saying; better safe than sorry. That's why I would wish to see some independent tests on this.

I expect to read more about how it work but not a single word till the end.

A long time ago, I once used a ionizing air purifier. Don't remember why, but I came to the conclusion it was better for rooms with nobody in them than for rooms with people in them. Also, they weren't silent, but close to it.

It's construction looks similar to Plasma Channel's ionic plasma thruster on YouTube.

From what I can see it is nearly identical if not identical in terms of working theory just a different form factor. Both are designed to move air so the only difference between a fan and thruster is how much air and how hard it can push.

It really makes me wonder what they got a patent on and if that patent will actually hold up.

Naming it after Vonnegut's world-ending ice polymorph certainly casts a bit of an ill omen over their tech 🤔
