An improved liquid cooling system for the Microsoft Surface Pro 4.

The 'hybrid liquid cooling' solution allows a better heat distribution, making the SP4 feel a bit cooler.
When running CPU intensive tasks, generated heat can be important for computers. On Microsoft Surface Pro 3 tablet, the heat, contacting with a copper heat pipe filled with water is transformed into vapor. Although effective, the heat remains concentrated in a particular area of the device.


In Surface Pro 4, Microsoft has improved the liquid cooling system.  Two liquid-filled heat pipes pull thermal energy from the processor. The vapor is diverted in two directions inside the SP4 to condense back into  liquid: one to the fan, and the other to a copper plate that sits under the kickstand.


The technology allows a better heat distribution, making the SP4 feel a bit cooler. Apparently, a similar system will be used in  Lumia 950 and 950XL mobile devices.
