Another Water-Cooling System For Laptops

Posted by timothy on from the don't-spill-anything-now dept.

big writes "NEC has developed the world's first slim sized water-cooling module for notebooks. It uses a piezoelectric pump driving method. This water cooling-module enables a highly advanced, slim sized, notebook PC with minimal operating noise." Toshiba has been working on water cooling in laptops at least as far back as the year 2000.

  1. OK, more efficient at cooling than a fan. by hashish · · Score: 5, Insightful

    But with laptops getting smaller and lighter, who wants a heavier bulkier machine that can run faster. Better off using a desktop if that's the way you want to go.

    Did you wet yourself, or did your laptop spring a leak?

    Secretary tells help desk, "I just spilled coffee on my boss's keyboard. What should I do?" Help desk pilot fish decides, "What the heck, it's just a $35 keyboard. Have her disconnect it and wash it out in the sink. If that doesn't work, we'll replace it." Next call is from her enraged boss: "Who the hell told my secretary to put my new $4,000 laptop in the sink and run water all over it?"

  5. I have a better solution. by robogun · · Score: 5, Interesting

    If heat is an issue, instead of attaching a huge tank to the side of a ghee-whiz watercooled notebook, why not build one using *underclocked* cpus and air cooling. Or use the crusoe. I don't know about NEC, but my personal preference is that my laptop be portable.

    It seems to me manufacturers think everybody wants one with desktop CPUs drawing 20 amps, just so they can say Lookie, my laptop runs at 2.8 ghz!!!!

    Run Crusoe, it's cool in more ways than one.

  6. Laptops - the spoilt kid in computing... by jkrise · · Score: 5, Insightful

    More attention that warranted seems to be the issue with laptops these days. So long as laptops run Windoze, what's earth-shatteringly different between different models? The true worth of laptops could be about $400 (what HP offered Thailand). Anything much above that is just waste of money.

    Rather than cooling, why not work towards standardizatrion on laptops. The power supply for these gizmos range from 8.6V AC to 33.4V DC. Power supply connectors come in all fancy pinouts and crazy designs.

    The lesser the laptops, the better it is for the environment. laptops break down more often thsan desktops (13.5 times more often actually) and are often ir-reparable, or too cost prohibitive. It's time there was legislation requiring standards on all laptops - those that didn't conform ought to be banned outright. This is a classic case of capitalism screwing global interests for a few dollars more.

    Hey NEC, we said we wanted laptops that are more PORTABLE, not more POTABLE...

  9. Just use a Mac for a Laptop (1/4th the heat) by Anonymous Coward · · Score: 5, Informative

    Forget water cooling.... Just use a Mac for a Laptop (1/4th the heat) for the same workload.

    Or even far more than 1/4th when doing benchmarks such as the open source RC5 cypto benchmark in which a Mac with a G4 in a laptop totally crushes intel offerings, not merely from its barrel shifter and not merely from a couple altivec instructions, but overall.

    Macs conserve batteries. Some older mac powerbooks allow you to run os 9.2.2 permitting virtual memory to be DISABLED saving more electricity from not needing drives spinning.

    Even a commmon 1998 powerbook mac could play an 130 minute dvd on one heavily used older battery, while no intel latptop in 1998 could play a 130 minute dvd without having to swap batteries at least once, I seem to recall.

    Most mac powerbooks never need to have their internal emergency fans kick on, even while crunching hard core mathematical benchmarks on warm days.

  10. Re:Truth Serum by FatPaulie · · Score: 5, Informative

    These three "selling points" to me just stress how prone to failure this product can be. I read it as follows:

    1. The water pressure sucks. 2. The thing is pain to put together 3. And the water will evaporate in a New York minute.

    Guess the writer was given some heavy truth serum before he wrote this one up.

    Read the article again, and you'll find that the author (this looks very much like it was Babelfished from Japanese source material BTW) makes those 3 statements about conventional cooling systems, not NEC's new laptop cooling system.

    The cooling system made by NEC has a small, high-pressure pump, the tank, pump, and CPU attached areas are NOT inter-connected, and no large tank installation is required.
