I'm wondering what the next step will be for the cooling systems within laptops? There's varying ways too cool a desktop computer most of which involve a fan of some kind, with differing power and sizes but asside from a fan again of various power and size there's no alternative way of cooling a laptop. Or is there? I'm running the new Retina Pro and thanks to the altered design of the fans it runs silent during easy loads even during light multi tasking you can't hear a thing, however of course it kicks into turbo when extra cooling is needed. This is a great improvement but on a conventional cooling system, what could replace the fan or work with it to provide enough cooling to keep temperatures at mid range levels during a heavy load? |

As far as efficiency the only replacement to Fans is the Liquid coolers... then again, they use fans on their radiators. On another note of efficiency, making the processors more efficient would help. If they put more energy into the work and less into heat dissipation then fans would not have to work so hard. The curse of our technology, nothings 100% efficient. I will say Intel's Ivy Bridge greatly helped in cutting the power they used... or at least I think they did. |

Whether you blow it away or transfer it to another medium to be carried away there will always be a need for the heat to be physically transported away from the components. This simply cannot be achieved by a 'no moving parts' system. There will always be a motor and a fan somewhere! There really aren't any great efficiency savings to be made. By definition, any electrical circuit, be it carved onto a chip or created from standard components must modulate and direct current. This requires resistance and resistance produces heat. It's inescapable. |

well there much better ways of cooling a laptop then a fan, a fan and heatsink is just smaller, lighter and cheaper. this is all hypothetical as i dont think these exist. the alternatives would make it bulky and heavy, passive cooling would be an option, turning the base into a big passive cooler, using heatpipes through the laptop connecting all the components like chipsets, memory, GPU, HDD etc (because you have to remember that it's not only the CPU that creates heat, removing the airflow would cause everything else to overheat and die quickly) and venting off the heat through a large passive cooler. you could also go with water cooling like this, but it would be more efficient way of cooling if the passive cooler was the back of the screen, but might cause issues with the screen getting too hot and dieing, but the water pupes could be routed to the screen onto a large passive cooler. this would also be a risk for leaks and such, and make it even heavier. |
