Asetek liquid cools a laptop -

While liquid cooling is seen as the domain of gaming rigs which cost more than Alexander the Great's bar bill, Asetek has been working out a way of making the technology more portable.

There are a lot of advantages. The biggest is that you do not need loads of fans which are so noisy they make Twilight fans look like Trapist monks.

Asetek  has built a prototype liquid cooling system for an Alienware M18x gaming laptop. Normally one of those will turn your groin to cinders as they run things like Intel Core i7 at 3.5 Ghz, along with a dual AMD Radeon HD 6990M graphics card.

A laptop running that sort of rig needs two or three separate cooling systems, with a fan and a heat sink for each CPU.

Asetek's big idea is to create a liquid cooling system that circulates through every part of the laptop that needs active cooling. It means that the laptop can even be overclocked without going the way of the Witch in the Wizard of Oz. The laptop still needed fans but they did not need to go like the clappers and were a little quieter.

Although the system is compact, it certainly is going to take up a lot of space and so being shoved under the bonnet of a cheap and cheerful laptop is unlikely.
