[TPU] SilverStone Tundra TD04 "Pump-less" Liquid CPU Cooler

[Accursed Entity]

From TechPowerUp article: "SilverStone Shows off Tundra TD04 "Pump-less" Liquid CPU Cooler"

Among the swarm of all-in-one liquid CPU cooling solutions SilverStone, the one that stood out is its Tundra TD04. It's what the company claims is a "pump-less" liquid CPU cooler. It features a high-performance CPU water block that looks more like the DIY blocks you'd find in expensive liquid cooling setups; plumbed directly to the 240 x 120 mm radiator+reservoir assembly. We're not quite sure how circulation happens, or whether it's convectional of some sort. SilverStone claims the cooler can handle thermal loads of up to 200W.

Ok, this got my curiosity, I had to share it with you guys. I wonder how exactly will this work, I'm not an expert in this area so forgive me if there's a simple answer to that. I guess the heat will drive the circulation somehow? This have been done before? Please share your opinion and/or your insight of how this might work.

so it kinda works like a traditional heat sink with heat pipes where the heat makes the liquid in the pipes rise up to the top where the fans will be cooling the fins?

 

I don't know how that would work with so much more liquid in the tubes compared to a heat pipe but i guess if there selling it its gotta work

Yeah, that's my thought as well, I'm intrigued... I'd love to see how it performs in real-world usage.

I really don't think convection would be sufficient to drive the liquid through the system. Wouldn't the coolant also have to be able to contain far higher temperatures than they would be able to in a standard AIO, considering the predictably low flow-rate?

It work like this:

 

Cpu heats the water in the block, this means that the density of the water in the block is lower than the density of the water in the res and pipes. So the denser cold water drops down while the less dense hotter water rises up. This causes circulation in the system, this effect is called the thermosiphon effect (passave heat exchange based on natural convection). This works similarly to a solar collector and geyser.

Silverstone had something like this at last years Computex. It works by using a liquid that has a low boiling point, the liquid vaporizes when it touches the CPU waterblock and travels upwards as a gas, when it hits the radiator, the gas condenses back into a liquid and flows down the tube, starting the cycle again. No pump needed since the system circulates based on the phase change of the substance.

SO it's essentially a big fancy heat pipe

Yup

thats awesome cant wait to see some performance numbers out

I like all in ones but the pump in most of them seem to be load, if this preforms well it will be a winner in my books

That's awesome, thanks for the info guys, can't wait to see some benchmarks with it.

So, 200W? It couldn't handle the highest end GPUs, but you could theoretically use a few of these to make a good properly silent PC. Not sure why you would want to, but whatever.

This isn't very new, i remember seeing this a couple of months ago, but it was then just some "look at me!" thing. Never heard something from it again, until now

(can't remember where i saw it)

You'd still need fans on the Rad.

 

I don't see the point in this really. If you're buying an AIO where the pump is either too loud or fails a lot, you're buying the wrong AIO

Well, maybe the point is not just the silence, a pump can fail(I know is not that common) but this won't have a pump so technically more durability? I may be talking nonsense thou... feel free to correct me.

This. Fans are easy to replace.
