Beginning Of the End For PC Noise 494

Posted by Hemos from the ah-the-quiet-machine dept.
An anonymous reader writes "If you work around computers a lot you are probably pretty tired of the noise they produce. The cutting down on computer noise has grown from the pet-peeve of a few people to a major segment of the hardware industry. If you are looking to cut down on noise there are a lot of ways to go, but one of the easiest and most effect is to upgrade to a silent power supply. This guide goes over and tests the four most popular ones on the market right now." A few years back, I had also written a piece about making silent machine as well. Any other hints from people?

So even though the first keyboards were silent, it became 'standard' to make keyboards have the clicks. The mouse just followed suit.

      I have a bit of hearing loss, and the noise a computer makes tends to garble any kind of conversation. I tried for years to get a relatively quiet yet powerful computer, and finally decided to physically move the bloody computer away from my ears.

      I purchased a Cybex Longview from http://home.hiwaay.net/~redwood/kvm/ [hiwaay.net], put my machine in a room off of my garage, and ran some STP between it and the recreation room. Unshielded is supposed to work, but the line ran past some flourescent lighting, so I became paranoid and bought Shielded Twisted Pair cabling.

      That took care of the KVM (1280 x 1024 works just fine on my 22" screen). For sound, I use a Terk product that transmits audio signals over phone lines, and ran a dedicated phone cord for this. There's a bit of hiss if I crank up the volume when nothing's playing, but if a game or other program is actually feeding the system, it's fine. The Terk feeds a 2.1 Klipsch speaker set.

      I stayed away from wireless solutions because my Siemens 2.4GHz phone system had / caused problems with most transmitter arrangements; this included the Terk wireless sound transmitter, as well as an older Turtle Beach sound transmitter set. After all, I am running a STP cable already, so running a dedicated phone cord isn't a big deal.

      Overall, it works great; the only noise I pick up is a bit of hiss if I don't keep the speaker volume low, and that goes away when I actually play music or games.

      There are a couple flaws. The biggest pain is when I need to swap CDs in the machine; Virtual CD programs can help here, but if you are making ISOs or burning disks, it's time to do a few laps about the house. The other pain is when I want to use USB; then I have to run into the other room to load / install the device. Also, you better be using a DB-15 video connection; I know of no inexpensive KVM extender that can handle DVI (I am looking, but most appear to be too near the $1000 mark for my taste).

      Total pricing was about $250 for the Longview, $50 for the cabling, and about $75ish for the Terk box. Sounds expensive, but A) it's still in the high end water cooling price range, and B) it is truly silent, with no dangers of liquid leaks. I've been using this setup for over 3 years now, and feel my money's been well spent.

    One thing that most people overlook is how tight their case is. If your tower is made of metal of any kind, make sure to eliminate any room for the walls to rattle or vibrate and that will cut down on noise by great leaps and bounds. Also, I try not to have my tower on a metal surface, because the vibrations also cause more noise than most people give credit to, or at least get some kind of boots under the machine.

    Anything short of this and you're doing to noise what we do to heat, moving the problem elsewhere. You could [for example] pump ice cold water over the heatsinks and keep the pump outside, in the basement, etc...

    But that's just moving the problem elsewhere and not really solving it.

    The solution is more scalable computing or appropriate choices. There is no reason, for example, why the P4 idles at 400Mhz and the AMD64 at 1Ghz other than the design can only scale so far. This matters a bit more in laptops where every mW counts.

    but one of the easiest and most effect is to upgrade to a silent power supply

    It has been years since I've used a PC where the power supply was a significant contributor to the noise, and even the bargain basement ones are pretty well behaved these days. Not only are power supplies generally pretty quiet, but the noise they do make is the gentle sound of airflow.

    Instead the low hanging fruit in aggravating noise are the hard drive, especially as rotational speeds increase (bringing the pitch to more and more irritating levels), optical media drives (though only when in use), and CPU fans. A quick up-and-comer in the ranks of audio assaulters are video cards, some of which come with ridiculously loud cooling contraptions.

    I've had a lot of cases and computers in my day. And the best thing for getting a quieter computer is bigger fans. Bigger fans have to spin at less rpms to push the same amount of air as a smaller fan. Less rpms means less noise.

    The real key here is not to go crazy with the cooling/overclocking. Giant heat sinks with crazy fast fans are loud as all hell. And often the default fan that comes with the CPU is sufficient.

    If you want more cooling than you need for overclocking the only real way to stay quiet is water cooling.

    But my recommendation is always to just run hardware at speed, default cpu fan, big intake and big exhaust fan running at lowest speed. You wont even know it's there.

    You need to defeat two major factors: fan noise and hard drive noise.

    Fan noise:
    -Buy good silent CPU fan (Zalman, etc)
    -Buy silent case & mainboard fans.
    -Have motherboard that can regulate fan speeds depending on temperature.
    -Power supply noise: it's the easiest part - buy better power supply that has no noise ($30 here make a world of diffrence).

    Harddrive noise:
    -Harddrive itself may be noisy, depending on speed/model, etc. Nothing you can do about it (except buy another).
    -Harddrive noise resonated in case: Solution is hard drives monuts on rubber pads- reduce noise, but not as much as advertised.

    Case is very important. Cases starting from $100 are more silent then average cases.
    Case can be temperature efficient and noise efficient.
    - Case temperature design: more expensive cases have better design/materials to keep system cooler. Means less FAN noise.

      Laptops run very quietly and consume very little power. Why can't they start putting some of this technology back into desktops?

    I recently built a computer for home (AMD64), and was disappointed in the noise level. It was still better than the noisy monster before it, but I've been working on getting it quieter.
    • Antec Sonata case with very quiet PSU, full fan control and vibration reduction for the drives
    • Zalman flower CPU fan
    • Zalman northbridge heatsink.

    My biggest problems now are the CD-ROM and the hard drives- I was kind of surprised to find the video card fan (ASUS GeForce 6600) is literally slient even under heavy load. I'm debating if the hard drive silencing enclosures are worth it- you can still tell the thing is on if you're within 5 feet, but unless the CD-ROM spins up you tune out the noise in a few seconds.

    I'd love to see a benchmark of "Quietest PC for a given performance level".

  • A small noise cancellation thingy that you can stick into the computer case and plug into a normal PC power plug such as a HD plug. I'd buy it!

  • To be honest, I've endured quite some time my ThermalTake Vulcano running at about 40-50Db thinking "the loader the cooler, and more hardcore / OC-abilities", accepting the soothing jetengine like produced whitenoise.

    But where I work they delivered new Dells, running extremely silent. After getting a PC in for repair and also having this contrast with my "hardcore Thermal Take" I went to investigate on silent Coolers, and they are en effect really quiet these days... (AMD Athlon, temps haven't been an issu

  • I find it's the best way to keep the computer quiet (but then the AC becomes the nosiest thing there :)). With an AC you won't need all the case fans, you can run your cpu fan at a lower speed and your powersupply fan (if it's intelligent can also run low speed)

    I had this problem. Loud PC, small apartment. Made it hard to leave on all the time downloading, um, updates...yeah, downloading updates.

    Anyway, before I decided to plunk down some serious $$$ on quiet power supply, case fans, new case etc., I figured I'd give quieting the thing down one more shot with just what I had on hand. Turns out, I could disable both of the loud as hell case fans. The overall case temp. went up several degrees, but the CPU and MB sensors only went up a couple. PC has been running 24/7 for almost 2 months that way now, during the hottest part of the year.

    One of my biggest pet peeves is HD whine.
    I usually have 4+ (up to 9 sometimes) pc's running here and among the fan noise, the HD whine is far louder and far more annoying. I am in the process of building a sound proof area in my office for the pc's.

    I moved all the pc's into a double wide closet and brought out my connections through a 16 port KVM to my desk. Next step is to install sliding glass patio doors on the closet so I can see inside and get inside to access them. I installed a QUIET bathroom type vent in the ceiling of the closet to exhaust the heat up into the attic. When done my noise AND heat problem will be almost nil.. I know it will work because I tested it by closing the original wooden doors. I just want the glass doors so I can see status lights and the like..

    Pretty cheap to do when compared to replacing all the PSU's and fans with water cooling stuff. The price of one set of sliding glass doors is about the same as one water cooled PSU.. When you are talking about quite a few of them like I am, it's an easy choice to make.

  • But I did put some work into it as well. There are two fans in my case, the PSU 120mm fan, and the 120mm fan that blows air through the radiator of my watercooling system.
    I am running an AMD64 3700+ that barely reaches 30C, even when the ambient temperature is 35C and the CPU is at 100%.
    My whole case is padded on the inside with asphalt/foam mats, which reduces the noise considerably. This does increase the case temperature, but the water cooling takes care of that effectively.

    The secret to reducing computer noise is to start by targetting the loudest component in the system. Quite often, that isn't the PSU, but the CPU fan. CPU fans tend to be smaller, but run at high speed so make much more noise than larger PSU fans.

    So, carefully stop each fan in your system in turn to see which makes the most noise. You will be able to tell becuase you will notice a big difference in sound when you stop the loudest one, while the others will make very little difference. Find a way to quieten it, and the repeat the process.

    My system is water cooled, and has three fans. Two are 92mm Panaflos running at 4.5V, which are inaudiable. The third is a 120mm PSU fan, which also cools the water, which I can hear and is the loudest thing in my system. With the window open, the system is totally silent, without it is just audiable.
