Vapochilled Pentium 4 System At 3.3GHz

SpinnerBait writes "Overclocking the Personal Computer has gotten considerably more elegant over the past few years and there is now an entire industry dedicated to it. One of the latest innovations is super cooling processors down to sub zero temperatures with standard vapor phase refrigeration, in an effort to allow clock speeds to crank far beyond manufacturer specifications. This article takes a look at the Asetek Vapochill, a Vapor Phase Refrigerated PC Case, that chilled a 2.8GHz Pentium 4 down to -7C and allows it to run stable in a workstation environment at 3.3GHz and beyond."

  1. More dollars than sense? by traskjd · · Score: 5, Interesting

    At such high speeds do you really want to spend heaps in order to go faster? I thought the general feeling was that people aren't finding much need for much faster processors. Like most /. readers I haven't read the article yet however I have seen these cases advertised and they cost a bomb. Without doing a price check it might almost be cheaper to buy several lower spec pcs if you want the overall power (say for the seti programme or cancer curing stuff). Just my 0.02c What do you think?

      You hit it on the head. 99% of the people who are doing overclocking like this aren't doing it on professional systems or work systems. And yeah, the price / speed ratio for doing something this complex is terrible. It's just the same as people who like to deck out their cars and tweak them to within an inch of their lives, etc. It's TOTALLY a status symbol within some nerd cliques.

      OTOH, some overclocking is very easy, and can add a lot of value. The first K7 chip I had, a 600MHz Duron was capable of being overclocked to ~860 MHz with the default cooler. That was good.

      The worst part is they only got this thing up to 3.3Ghz, that's 500 extra Mhz.

      Quite a lot of work, money, and mess for 17% more CPU performance. In a month or two they can probably just buy an official 3.3Ghz chip.

      Not only that, but if they actually want to spend money, they can just go out and build multiprocessor systems. Yes, yes, not everything is multithreaded, but I think it gets you a heck of a lot more than a 17% performance gain on average. And it won't catch fire if you spring a hose! Overclocking was origionally for the cheap buggers who figured out they could buy a slower chip for $$$ - $50, instead of a faster chip for $$$, but you could make them run the same. Now it's all about the $$$ - $50 for the chip, + $$$ for the cooling system.

      On the other hand, it's a hobby. And probably a fun one. Like tricking out cars, or BASE jumping from higher hights... It's not about the sense, it's about the numbers, beating your personal bests, and quite possibly the cool noise this system would make when running. Just to say you did something a lot of other people haven't.

    Is the gain really worth it anymore? I still have an old 1ghz laptop. I use an ancient 333mhz desktop. My server is an extinct 133mhz. I'm all for the "I'll do it because I CAN" attitude, but wasn't overclocking originally for serious benifit? Like 100 - 133mhz? Thats a 33% increase. 2.8 - 3.3 is only about 2%.

  6. adding processors? by FaRuvius · · Score: 4, Insightful

    at this price point, shouldn't people be thinking about adding additional processors, instead of overclocking 1 processor?
    That seems like the better path to follow from a price, performance, and stability standpoint.

  8. stupid overclocking and case modding frenzy by chamenos · · Score: 5, Interesting

    gone are the days when overclocking was actually an economically viable option to get more performance out of your system for what you pay. these days, overclocking is almost no different from case modding, in that its just for posers to make themselves feel better and have something to show-off.

    and is it a good sign that slashdot is continually posting articles pertaining to both case modding and overclocking "breakthroughs"? yes, they overclocked the system to 3.3ghz, but most likely in a few months intel is going to release processors that are just as fast, if not faster. see the pointlessness?

    its like posting on article on slashdot about a breakthrough in man-powered vehicles, about how 200 people got together to push a car to more than 200km/h (i refuse to use miles/hour). yea sure, that was fast but is it a breakthrough? currently, the approach to overclocking processors is to up the voltage so the processor can function at a higher clock speed reliably, and then find some way to cool it down sufficiently so it doens't overheat. so they got it colder this time, and faster, via the exact same approach thousands of overclockers have been using all the while.

    is this really news-worthy on slashdot?

  9. heatpipe by goombah99 · · Score: 4, Interesting
    How come no one seems to be using heatpipe technology to cool things? THis would seem to me the natural way to extend the cooling range of passive systems. It probably wont ever have the massive effects like these acively chilled systesm but it would cheaper than thus more worth while.

    the idea is simple. on top of the chip one places a vertical tube with the same crossection as the chip. The tub is filled with alcohol or propane or freon or other low boiling point liquid. The sides to the tall(!) tube are lines with air-cooled heatsinks.

    when the liquid boils then the (VERY LARGE) heat of varorization is extracted from the liquid. the expelled gas molecule rapidly transferes its energy to other gas molecules and then distibutes that over then entire face of the heatpipe which condences the gas back to liquid.

    the processor can never warmer than the boilingpoint of the liquid. the average cooling capacity is determeined by the requirment that the cooling rate of the heatsinks equal the heat input rate on average. One of the nice things about this as opposed to a fan or refregeration system is that although the average heat load is the same, the peak heat load can be as high as you want. the liquid has almost infinite reserve cooling capacity up until it boils dry. Thus the temperature of the processor fluctuates less than any fan cooled or refrigerated system.

    So what is the heat load capacity. It should be the significantly larger than any refrigerated system with the same area of heat sink!!!
