  1. for the money by NotAnotherReboot · · Score: 4, Interesting

    It seems to me like it'd be a better idea to build a system that isn't quite the highest end, and don't buy expensive overclocking equipment. Then, when it seems to be getting a little slow, buy a new processor that will likely be faster than anything you could have overclocked for the same or less money. Sure it sounds cool to say you have an ultra high clocked system, but in 6 months when there's faster non-overclocked, who's laughing?

      Depends on the productivity all that over clocked processor did for me. If I was able to run vi at 2Gigahertz while everyone else was coding at 1.5Gigahertz then I would have produced 25% more code than them. Over the course of 6 months or more that could be a lot of code.

      Its all about economics of scale and if I am going to get 25% more code write because of over clocking than I am far more profitable that the next guy period.

  5. Beware of bad advice! by uncle+isaac · · Score: 4, Informative
    Thermal compound is optional and isn?t required. If you?re going to use thermal compound, I suggest you scrape off the thermal pad on the bottom of the Volcano 7. We suggest the use of Artic Silver II which is one of the best thermal compound solutions available. This can be found for $8.50 from our friends at Heatsink Factory as well.

    A few weeks ago, I finished putting together a shiny new Athlon XP 1900+ for my son, and was very disappointed to see that heatsink grease is indeed necessary on the newer processors. The CPU and power supply fan worked just fine, the heatsink was in very close contact with the CPU, but there was no grease. What happened when I turned it on nearly made me cry: the CPU overheated within minutes of seeing the KDE desktop on this new system, and I was out $200 for a new CPU.

    I learned my lesson the hard way: don't try to skimp on thermal grease, especially on the new Athlons. They run hotter than ever now and you're risking your system's life if you don't take the proper precautions.

      What is meant by this is that replacing the thermal pad with thermal compund is optional. You definatly need a thermal conductor between the heatsink and the proc. That's just common sense.

      You are basically saying that the thermal threshold went undetected by the cpu and the chip fried instead of the system trapping to the shutdown code. Wow! Was it running Linux or Winblows?

    3. Re:Beware of bad advice! by markmoss · · Score: 3, Informative

      It was Linux (KDE), but this is probably hardware, not OS related. AFAIK, shutdowns due to thermal thresholds being exceeded are done by the hardware alone, with no input to the OS. (This does give you a shutdown without proper preparation by the OS, requiring a file system check when started up again, but if your box waited for Windoze shutdown the CPU would fry for sure...) Or does anyone know different?

      The newest Intel CPU's will detect overheating and either shut themselves down (P3) or throttle back the clock rate (P4); it's not an OS function. Athlons have a built-in temperature sensor, but depend on motherboard circuitry to act when the temperature rises. And until quite recently (when a hobbyist magazine demonstrated Athlons melting down when the heatsink fell off), the circuitry recommended by AMD didn't react quickly enough to save a chip that wasn't thermally connected to a heatsink. (At least not where 800MHz+ systems are concerned; older, slower CPU's just didn't heat up that fast.)

      Read the last sentence of the article. It's very clear that they didn't build it - rather, they just culled through product listings of items that had decibel quotes. When a "review" tells me that the finished product "should" produce less than 30 decibels, they've completely wasted my time. This was nothing more than the journalistic equivalent of a high school book report.

  7. I like the noise. by dbCooper0 · · Score: 4, Funny
    That way - I can tell when a fan is failing well before the situation is critical - there's nothing like the noise from 3 or four boxen in close proximity, and to hear the HDs (two to four per box) as they recalibrate, seemingly from old age. Surround-Sound in a natural occurrence...

    And the fans - (one to two per processor) complement this ambience with a critical indicator to health - ie: they usually start making a hell of a racket when starting to fail - along with the power supplies' fans. Time to start checking things out before your sense of smell takes over!

    Of course, your mileage may vary.

    Yes, and it's dirt cheap and easy.

    1 - build a wooden case that allows you to slide the computer into it with about 2 inches of space all around. insulate the box with sonex. or hospital bed padding (same stuff, and loads cheaper.) make the door out of plexiglass, 2 layers spaced about 1/4 inch apart and not parallel to each other (I.E. a slant on the inside pane.

    on the back you add 2 ducts, one high, and one low. duct these with dryer vent outside the room and place a blower on the out vent, a small filter on the in vent ( the in must be in the building, the out can be vented outside.)

    Voila, 100% silent PC god enought for a recording both (well that's what we use in our sound booth. the equipment registers no sound change at the microphones with the computers in the box on or off. or with the blower on or off. and a human cant tell either.)

  9. Re:Noise Schmoize by Barbarian · · Score: 4, Interesting

    Yes, you just need to add noise-dampening panels to the sides of the case.

    A lot of the noise you hear when the case is closed is the case resonating at the 1/2, 1 and 2 * wavelengths of the sound coming off of the cooling equipment (the fans tend to put off white noise of many wavelengths).

    You just gotta make sure you aren't obstructing the airflow. I'm going to do this myself, and on my case, you can put panels on the left and right, top and bottom without obstructing airflow. Front and back have to remain unblocked, although the front is possible to do too if room is left where the built-in vent areas are. Worse designed cases may make this impossible.

    The stuff I'm going to use goes for about $4 per square foot, and is about 1/4 inch thick.

    If you can't get this type of noise-reducing panel from your local computer retailer, go to a hardware store and get drop ceiling tile, as thin as possible (preferably 1/4 inch if they make it), cut it to size, and glue it into your panels.

  10. Quiet CPUs by kcbrown · · Score: 4, Interesting
    While the Athlon is far and away a better deal than the P4, there's one thing the P4 has in spades over the Athlon: it does exactly the right thing when it overheats -- it steps down its speed.

    Now, most people aren't going to care about this but those who are trying to build a quiet PC are -- if you put a P4 in your system you could conceivably cool it passively and take the performance hit. I don't know how much of a performance hit you'd get by cooling passively versus actively but the video on Tom's Hardware about what happens when you remove the heatsink from various processors shows the framerate of Quake III returning to something close to the original just by reattaching the heatsink to the P4...and the fan isn't running on it at the time. Of course, that's probably because the heatsink itself is cool and will warm up significantly after being attached to the CPU for a while.

    My question is this: what heatsinks exist out there that are designed for passive cooling purposes? I'm sure the design of such heatsinks differs significantly from those designed to accomodate a fan.
