Danamics liquid metal-based LM10 CPU cooler

Denmark-based Danamics has developed its first product, and it looks pretty special. The LM10 is a liquid metal based CPU cooler that combines liquid metal with an electromagnetic pump. It is claimed to be the world’s best performing air-cooler and have cooling capabilities that exceed those of most water-cooling systems.
Cooling of semiconductor hot-spots has developed into a demanding task. In recent years the high power density of microchips has increased rapidly, thereby increasing temperature and temperature non -uniformity on die and across chips. The drive for extremely low thermal resistance if further accelerated by the trend towards smaller system enclosures which has made the cooling task even more difficult. This gives the cooling companies a new challenge. To create cooling devices that is reliable, efficient and compact. Danamics does all of those.

Danamics got a lot of attention a while back when stories started to go around that it had a new kind of CPU cooling in development. It was said that Danamics had been able to harvest the power of liquid metal. Not much information could be found on the website, until now. Danamics has updated it with what it calls the worlds first commercially available liquid metal based CPU cooler - Danamics LM10. Danamics mentions two key characteristics when describing the pump: the unique electromagnetic pump with its patent pending multi-string design and the liquid metal with its superior thermo physical characteristics.

An electromagnetic pump has the advantage that it has no moving parts and emits no noise or even the slightest vibration. Danamics says that it's new multi-string electromagnetic pump eliminates the need for a high current requirement and delivers a high flow with minimal current input. The mere size of the pump also makes it very flexible and it could be used even for laptops.

The liquid metal is a key component in Danamics cooling systems. Liquid metal has two major advantages when cooling high power density heat sources:
  • Firstly it has superior thermo physical properties that decrease temperature - and temperature non–uniformity - on die and across chips.
  • Secondly the electrical properties of the liquid metal enables efficient, reliable and ultra compact electromagnetic pumping without the use of moving parts, shafts, seals, etc.Liquid Metal has numerous key advantages compared to competing technologies, such as water-cooling or traditional air cooling. The most important ones are:

Ultimate performance

Danamics LM10 is the world’s best performing air-cooler. By utilizing the unique properties of liquid metal, the cooler has the lowest thermal resistance of any air-cooler in the market. The cooling capabilities exceeds most watercoolers in a single device.

Easy mounting

Compared to competing solutions, the Danamics LM10 is a true all-in-one product. There are no external housings, large reservoirs or bulky radiators. With liquid metal cooling you have true performance in a compact, self-contained unit. This makes mounting a breeze and the Danamics LM10 cooler can be mounted in minutes.

No moving parts

The superior liquid metal brings another advantage besides its efficiency. The properties of liquid metal make the use of an electromagnetic pump possible. Danamics’ patent pending multi-string pump delivers high flow combined with a very low power-draw of less than 1W.

No noise and no vibration

Compared to watercooling pumps, the electromagnetic pump used in Danamics LM10 cooler has numerous benefits. It is hermetically sealed and has no moving parts, which means that no noise or vibration is added to the system from the electromagnetic pump. Also the pump is orientation independent, which ensures maximum flexibility for users and system integrators.

Innovative technology

Danamics LM10 is built from the ground up using innovative technology. The combination of liquid metal and an electromagnetic pump is all new in commercial cooling devices, bringing true high-tech to your desktop.
