Silverstone demonstrates pumpless liquid cooler at Computex

[Vanth]

Silverstone invited me over to their booth at Computex Taipei, where something hidden away in one of their cases caught my eye: a closed-loop CPU cooler without a pump. Normally such a cooler would have a small pump above the CPU, but this cooler simply has liquid pipes connecting straight to a metal heat-dissipating block.
The way this cooler works is through a special type of evaporative liquid, which flows through the pipes when it absorbs heat from the CPU block. The liquid is capable of providing similar cooling power to traditional coolant when paired with Silverstone's radiator, so the pumpless solution doesn't impact performance.
What's even better is that by removing the pump, there's barely any noise emitted by the system, especially when paired with a passive radiator. Silverstone love their quiet products, which is why they've spent time thinking of ways to reduce the noise of liquid cooling solutions such as this.
Unfortunately Silverstone tells me this pumpless cooler is just a prototype that's unlikely to come to the market at this stage. The company says this type of closed-loop cooler is very expensive to produce, and it's unlikely consumers would be willing to pay the extra cash just to remove the pump.

As a watercooling aficionado, I am quite excited about this. They say it's expensive, but I'd be willing to pay for a noiseless, utterly cooled-down machine. What are your thoughts about this?

The concept isn't much different than heat pipes used for air coolers. They are not confident in bringing it into the market now is probably because it does not have the flow rate of a pump, severely crippling its performance against other AIO watercooling and provide no benefits over air cooling. Plus, does this evaporative liquid work better (in terms of how much heat it can carry) than the liquid currently used in ones with a pump?

I would be very interested if they've managed to address the possible issues after more years of R&D. As of right now, I think it will be too expensive, performs worse than an AIO with pump and only performs as well as air coolers.

I knew that looked familiar.. https://www.youtube.com/watch?v=XT9IzD94ATg
Except that video is a year old from last year. If they have no intent to release it on the market then they need to stop teasing us with it year after year.

u need a better condenser then a radiator.

It wont work... because those rads were not designed to have air pockets.
Also i see a problem when temps raises too high, and pressure forms.

Pumpless AIO cooler certainly would be nice. The pump on my H100i just started making ticking noise last week. Scared the hell out of me because I thought my hard drive was going bad, but it turns out it's just the H100i. Now I have to go through the hassle of RMA'ing it. And to make it more annoying it's not on my CPU, it's cooling my R290 so I'll have to put stock cooling back on 290 which involves more than a dozen little screws... sigh...
