Computing power increases rapidly in accordance to Moore's Law, the model that has accurately predicted that the number of transistors in a microprocessor doubles every 18 months. Today we have billions of transistors in our machines consuming an incredible amount of power per unit of area. So much, that the heat generated per unit of area of a CPU die is several times that of a hot plate, and even gets within the realm of heat generated by a nuclear reactor when overclocked.
To combat the heat, Asetek have produced a water cooling system for notebooks. It combines heatsinks attached to the GPU(s) and CPU through water channels, ensuring that each component can be cooled effectively. The advantage to this setup is that every heatsink dissipates heat for the entire system, rather than their respective part. It's also a lot quieter than traditional air based cooling systems in gaming machines.
Asetek demoed this new tech inside an Alienware M18x, with claims that they were able to successfully overclock the Intel i7-2920XM from 3.5GHz to 4.4GHz, and the AMD HD7990 GPU to 800MHz from 680MHz. The final result was a 23% higher 3DMark Vantage score. You can see the details of the setup in Asetek's demo video below.
The system is similar to the closed loop pre-assembled kits found on the desktop market, where Asetek already dominate. If you've got an Intel, Antec or Corsair branded water cooling kit, chances are that it's a rebranded Asetek system.
We expect that this tech will become popular in bulky enthusiast machines where portability and battery longevity isn't a major concern.
