    now if they could only make something for a set of rack-mounts.......

    I have moved my very noisy server into a kitchen closet that previously held a small refrigerator. So it has a power outlet and is well ventilated. No more noise in the bedroom (at least from the server ;-). And buying wireless LAN equipment to connect the server to my laptop costs less than the quiet case in the article.

    I would think that the fleece would reduce heat transfer. The noise is a big plus, but isn't there some way to get quiter without losing heat transer. In our apartment all the computers run hot. And some reach dangerous levels periodicly. I woyuld also think that the felt or fleece could also blaok airflow if your not careful also hurting heat transfer.

    I've found the noise from the Athlon 1800+ in my bedroom to be quite soothing in the amount of white noise it creates in the background.

    I did a little somewhat unscientific case study on the white noise it generated a few months back. I started shutting the box down at night while I was in bed. It turned out after 1 week of shutting it down to get rid of the noise that I actually had a harder time getting to sleep, and often woke up in the middle of the night. Within a few nights of leaving it on all night and day again I was back to sleeping like a baby.

    With a baby on the way I'm tempted to set up a computer in the baby's room, not only so I have something to do at 4AM in the morning between feeding/changing, but also as an introduction of white noise into the room. I guess I'll see how well this works, maybe it'll be as soothing his mother's voice.

    I've been running a reliable water cooled setup (including many moves, dropping upside down, upgrades, etc) for over 6 months now. It works great. I have install details [nyx.net] written up for anyone who's interested. The noise went from deafening to a mild hum.

    I'm currently gathering pieces for a passive watercooled setup (no fans) that handles cooling the video, system chip and processor. The power supply fan will be removed and replaced with a low-voltage 120mm top-mounted fan that runs silently with good airflow (for HD cooling as well).

    Rather than mount the radiator inside the case, the radiator will be top mounted with a custom lexan mount. This moves the heat outside the system (closed box). In addition, the inside will be sound deadened with leftover Dynamat Extreme [dynamat.com] from my car stereo install. This should result in a cool looking, silent machine, with no compromises. It isn't going to be cheap though.

    rack sound reduction is very very easy. I have a set of six racks that are nice and quiet, the air conditioning coming from the ceiling for us humans is louder.

    First, you MUST have racks with doors on front and back, second you must have a plenum on the bottom of the rack and the AC drop in the top (or my raised computer room floor with a Libert unit in the other room feeding the floor with cold air, vent out the top back to the AC unit) We placed car audio damping material (Dynamat) on the solid doors and sides, and ther front smoked plexi door is left normal.

    with the doors closed (Oh add felt around the doors for a sound seal) you can barely hear the 14 servers screaming along (anyone notice hoe ML530 fans sould like jet's taking off?)

    What about the Apple Cube? No noise came out of that sucker!

    I tried 3 types of "quiet" fans and sound absorbtion padding and what worked the best is a Zalman flower cooler. They are about $28 with a speed adjustment control included. With my Athlon XP 1800, I was able to reduce the speed to the minimum with only a 4C hit on temperature from my ultra fast CPU fan I had originally. Now the next source of noise is the fan on my video card!

    Go ahead and ignore the numerous studies indicating that white noise can help you sleep.

    A perfectly quiet room is not conducive to a good night's sleep - you wind up being woken by small noises, such as the house creaking, wind blowing through trees, the HVAC system coming on and turning off, etc. White noise gives a higher base noise level that makes these events less noticeable because they're not such an abrupt change from what's in the room otherwise.

    did you get to sleep before you had a computer?

    Most people leave a fan running in the room - not only does it generate white noise, but it helps air circulation and keeps the temperature more stable.

    These guys [uci.edu] seem to claim the noise is good for you! I quote the bit of interest for the guys to busy to read the whole thing.

    A recent advancement in technology that is becoming widely used in psychological counseling and health service settings is the random noise generator. These devices, similar to the size and configuration of a smoke detector and/or an air purification device, emit a wide frequency band described as "white" or "pink noise." Adjusted to a relatively low level, these can be effectively utilized in the spaces in which the client interaction occurs to mask undesirable environmental sounds without negatively impacting the client interactions by being intrusive in nature.

    AFAIK the noise from a fan is pretty close to white.

    Seems that in medicine though there are always conflicting studies so I expect to be presented with the opposite result in a case study.

    Seeing this post I just remembered that research is going into subjects such as noise cancellation and the like. Doing a bit of googling I quickly hit upon this faq [erols.com] on Active Noise Control.

    Seems to me that this technology would be ideally suited to solve the problem of noisy computers.

    I'd love to see Creative, for example, releasing some new hardware/drivers to help out in this area!

    In the meantime, maybe I'll get myself a pair of these [nct-active.com].

The Force is what holds everything together. It has its dark side, and it has its light side. It's sort of like cosmic duct tape.
