  1. Re:Straight up once again by eander315 · · Score: 1 · on Corsair Demos Easy Watercooling PC Rig
    There are functional reasons for the vertical placement of incoming and outgoing lines on a waterblock. Generally they are situated that way to avoid tight, flow-reducing turns. This is particularly important in designs that rely on jet impingement (like the Little River Storm G5) to cool the CPU. In these designs, the incoming water is directed forcibly onto a small central area of the waterblock base located directly above the CPU die. Typically the outgoing line will be off-center, and in some cases there are two outgoing lines.

    It wouldn't be that difficult to make a waterblock that fit in a 1U rackmount space, but the cooling efficiency would be greatly reduced due to flow restriction. A design similar to the Danger Den Maze 4 GPU block would be the most likely candidate, IMHO. There are people working on this already, and discussions about it can be found in the ProCooling forums.

    But, really, all of those fan and water and air-conditioning based cooling options are just really good ways to make your office or computer area really friggin' loud.

    You didn't read the article, did you? Stirling Coolers (and I assume Pulse Tube Coolers) make very little noise due to the need for minimal friction. No air is actually moved by the engine (although there is a Helium working fluid sealed inside the engine) so there's no blowing noise, either. The largest concern is vibration, but such vibrations would be no more than existing fans.

    And hey, how can you not like something that can make instant liquid nitrogen? (Look at the frost on the right end of this picture) I think I'll get one of these and start producing my own rocket fuel. ;-)

    And for the serious overclockers, we have low powered cryogenics coming down the pipeline. It turns out that Intel is considering the possibility of using Pulse Tube Coolers for the next generation of thermal management. (Hey Intel, you think that over 100 watts might be just a *smidge* much for a processor?)

    While there's something to be said for this step being rather extreme, it might lead to the development of cryogenic computers. These futuristic processors could utilize super-conducting transistors and wires to improve performance and eliminate waste heat.

    Kind of a weird thought, but there you have it. :-)

    Personally, I'd like to see Stirling or Pulse Tube Coolers replacing existing phase-change air conditioners. In the name of "energy efficiency", you can't buy a decent apartment AC and are forced to deal with putting one in every room. Stirling engines could provide better cooling for less energy! Now if we could just get the buggers mass produced to bring down the cost...

    But if you're naive about the net and you go online maybe once a month...then you're a raw piece of meat in a pool full of sharks.

    I am one of those naive that really don't have a clue what hardware review sites to trust. My comfort is that I am probably far from alone, in this matter.

    To assist me and other naives(sp?), please join this silly poll and review the following sites (regarding credibility) with a scale ranging from 1 to 10, where 1 is "No credibility at all" and 10 is "Perfect credibility, these guys wouldn't post a biased review for world domination":

    If you know only a few of them, give your opinion on those.

    Maybe someone with the right facilities could set up an independent poll?

  6. Re:Antifreeze by Firethorn · · Score: 2, Informative · on Water Cooling With A Car Radiator

    Antifreeze may be the cheap solution, as many people have some left over for their car, but it's not ideal. I've read that Glycol only has about a third of the heat transfer ability of water. Thus the idea of the "water wetter" type products. You don't really need the glycol, you need the anti-bacterial and anti-corrosion treatments. So they made a product that contained them, along with something that reduces surface tension (better cooling).

    This site has some advice

    But I'll say that I know that antifreeze has anti-biological properties. And if you use it, you can probably leave it alone for alot longer than a year as long as you have a resevoir and keep it topped off. My antifreeze is good for five years in my car.

  7. Re:The answer you didn't wanna hear but may save t by timma · · Score: 1 · on Tom's Guide to Water Cooling

    If it helps, I run ALL the big fans (cpu + 3 case) @ 7v instead of 12v in my PC tower which makes it quite a lot quieter - with no overheating problems. Not sure how hard this is with a MAC, if the fans are powered off molex connectors very easy. see http://www.procooling.com/articles/html/quiet_fans _-_power_control_met.shtml for details. (I'm in no way affiliated with the website). Bear in mind though that I live in England which is a cold country! If your machine room/office/whatever gets hot, I wouldn't bother.
