Editor's Note: While Computex took place last week and all of the news announcements are behind us, we're still sorting through hundreds of in-person meetings and demonstrations, picking out just a few more of the most interesting items we saw up close.
Water cooling has gained a lot of popularity recently, but one of the bigger problems people keep running into is water pumps that break. If that's not an issue, cheaper water pumps are also often quite noisy, defeating the purpose of cooling your system with water.
SilverStone showed its new TD04 pumpless liquid cooler at Computex 2014. This unit is a 240 mm water cooling unit that plainly doesn't have a pump. The only parts include the water block, clear tubing, radiator, and the fans. The unit is filled not with water, but with a liquid with a very low evaporation point. As a result, it feels cool to the touch, yet the water keeps bubbling inside the loop, which looks quite magical. SilverStone won't reveal what liquid the unit is filled with.
Cooling power is not one of the TD04's strong points though, as it is rated at a maximum TDP of 200 W. The idea behind this cooler is not to break new ground with cooling power, but rather to create a system that is pretty much perfectly silent, assuming you use the right fans, of course.
Hopefully, we'll know more about this product as time goes by. We'd really love to test something like this to see if it is a viable option for long-term use. Do note that the unit is still a prototype, so it might never actually reach the market.

The hot fluid rises and forces the colder fluid down. You can break the laws of physics, should be pretty reliable as long as the fluid moves quickly (perhaps the hotter it gets the faster it moves as well).
Would be pretty awesome to have a computer cooled by a lava lamp, must be said.
I think it may have more to do with other companies trying to replicate what SilverStone has done. ; )
Now what IS interesting is that this technology has been around for awhile, but not in a closed loop like they are showing (at least I haven't seen it). In an open loop, you can simply use evaporation to move the liquid and generally your heat source (or your block) would need to be higher then the radiator. But like firefoxx04 said, they might be using the same principle as a Block Heater although in reverse as that concept attempts to keep the engine warmer in a colder environment.
Can't wait to see some testing done.
chances are it's 70% ethanol or something. which would make sense since ethanol has a MUCH lower specific heat than water
Ford's Ecoboost turbocharging system doesn't need idling before shutting off because the coolant flows through the system without a pump too.
Heatpipe technology can fluid (coolant?) in it that flows with the same concept.
I'm rather curious what thermal currents could do in a normal system using water, where the cooling tower is positioned higher in elevation, with the inlet on the low portion of the radiator and the return line on the higher portion of the radiator. Like the positioning of a passive solar water heating system.
And...why isn't this product on the market yet?
A "block heater" on a car, is nothing but a heating element that's inserted into the block. This idea is completely different.
@Danwat1234 - Thermostat is usually on the outlet ("hot" side), but doesn't have to be. There are designs where the thermostat is placed in the inlet ("cold" side).
