  30. Makes sense only if seriously upgradable by heironymouscoward · · Score: 2, Insightful

    The case is very cool (metaphorically) but looks like it will cost somewhat more than the innards of the PC. In that case, I would hope that it'd last at least 5-10 years, meaning several upgrades. Given that motherboard changes seem to make this pretty much impossible, I would rather buy a cheap case and stick the whole thing in a separate room.

    For notebooks, this looks like a good technology: notebooks cost more anyhow and you can't really stick them away in a room somewhere. Plus, most notebooks really suffer from heating issues, and an on-off fan tends to be more annoying than a constant hum.

    But best of all would be a way to turn excess heat back into power. Heatpumps of some kind?

    Just an idea...

    Instead of blowing air around, putting hoses in your computer or using heat-pipes, would it be possible to submerge the whole motherboard and hard-drive in some non-electricity-conducting liquid? De-ionized water???

  32. Fanless = dust free? by slim · · Score: 4, Interesting

    Correct me if I'm wrong, but if there's no air-cooling going on whatsoever, does that mean the case can be completely sealed against dust?

    I'm sure inhaling the dust that collects in computer cases is a health hazard, if you do it often enough.

    OK, this is the complete text translated (and I have to add, this guy gets *pretty* emotional about this case, and uses a lot of colloquialisms).

    Zalman fan-less PC

    Preamble:

    Finally, never-ending silence in the box. It took a long time for a product like this to be produced for the mass market. The manufacturer likely will be swamped by the large number of pre-orders. While its technical specs already convince us on paper, we are waiting for the first samples and pricing information. But one thing should be clear right away: The price will be way below any self-made constructions, since Zalman is known to specialize on uncompromising mass production. 6 heat pipes for the CPU and two more for the graphics card, as well as 10 for the hard disk should keep the system optimally cool. Let's look forward to it, and start saying good-bye to all these fans and noise makers right now. I hope it's christmas soon :-)

    Well, what more can I say, the cream of the crop. It brings tears to my eyes. More heat pipes (18 of them!!) and cooling elements than you ever wanted.

    Silence in its perfected form, since this is a completely closed case. The first PC case where also optical drives can be de-coupled and their noise dampened.

    More is not technically feasible!

    More silent is not possible!

    From october on, this case will be available at www.alternate.de

    So, start saving now!

    And of course, I'll keep at it. (I guess the author means he'll post updates)

    I can neither speak nor read German. However, I can make sound judgments based on detailed pictures. I know a great deal about computer cooling systems. The detailed pictures are provided, so I will share my opinion.

    The surface area of the pipe is significantly diminished compared to other similarly designed systems. This leads me to believe that there will be much more "air heat". Fortunately, this shouldn't affect the circuitry.

    Another difference I picked up on immediately is the use of motor oil as the cooling fluid. This will mean that the entire chassis will be at least 5 pounds heavier. Not a big concern for most.

    The final aspect I will comment on is the use of "induction through aerodynamics". I will only say that you better have your air conditioner blowing toward the computer, or better yet, a small fan.

    Preliminarily, I give it a B-. I do hold out hope that it is better than the pictures show it to be.

    Whilst I like the case it's a bit pricey. In fact it costs 3 times as much as the lasty base unit I bought.

    You can achieve a quiet PC for much less cash. I bought:
    A Big HSF with 80mm temp controlled fan (normally runs at 200rpm).
    A Fortron PSU with 120mm fan.
    2 temp controlled case fans which run at 1300rpm

    For about $100 you can make your machine so quiet you can barely tell it's on.

    [uhm "(un)endliche Ruhe im Karton" means so much more though :-)].

    This refers to "peace/quiet [Ruhe] in the case/box".

    [ "Ja naturlich bleibe ich am Ball ..." ???]

    "Naturally I remain on the ball" - "On the ball" is a colloquialism that means "attentive" or "vigilant".

    It makes you feel all soddy inside [ "Da bekomme ich feuchte Augen"].

    "My eyes [Augen] get moist", i.e. "I am emotionally/spritually moved".

    You don't really need to go this far to achieve silence. At least, not for sufficiently small values of silence.

    Check out the new Apple G5's cooling system. It uses a ton of ultra-quiet fans instead, moving high-volume low-speed air over the components. It puts out 35dbA, which is less than even a fairly quiet laptop fan these days.

    Now, admittedly the cooling technology isn't as creative, but considering that for $670 more than the estimated cost of the case alone here, you get a nice IBM 970 processor, hard-drive, OSX, and a lot of other goodies, that's really not a bad trade-off.

    And yes, I took the high end of the estimated case cost ($1100) and the cheapest G5 ($1770). But still.

    Heat pipes generally don't contain water but some other kind of solvent which is specific to the temperature range they want the pipe to work at. Generally it's not particularly conductive, but a bit flammable, not that there is enough heat to ignite it in a PC. Leaks would also tend to be slow and could be picked up by a rise in temperature.

  40. Re:More silent is not possible? by Apogee · · Score: 2, Informative

    Actually, as shown on the spec sheet pdf which somebody else in this thread linked to, the box uses a "No-Fan Power Supply" employing "MPPT technology and the HSC method" ... in brief, heat from the PSU seems to be transferred to the case shell, which acts as heat sink.

  42. Re:nothing in nature is instataneous? by HardCase · · Score: 2, Informative
    I think it all depends on how you quantify an 'instant', i.e. how many fractions of a second is it?


    In context with the post to which you are replying, "instant" would mean zero delay from one event to the next, that is, zero fractions of a second.


    If there is a delay, any delay, even the tiniest fraction of a second, then it's not instantaneous. Maybe it's "almost instantaneous".


    I realize that I am straying somewhat off topic here, but to give an example, the memory modules that I design, simulate and test have a transmission delay of something on the order of half a nanosecond from a register to the memory device. That's .0000000005 second (5x10^-10). Is that instantaneous? Not in my case. That's a significant amount of time because when all is said and done, by the time a memory cycle is finished, I may only have 50 to 100 picoseconds of time left over.


    The long and the short? "Instantaneous" means zero delay between one event and the next. "Almost instantaneous" is something else.
