Silencing a Hard Drive Using Household Items

Reader Justblair recommends his blog entry detailing how he made a hard drive silencer for a pittance. "This article demonstrates a very easy-to-make hard drive silencer that not only outperforms most commercially available devices, but is cheaper to implement as well. Requiring very little in fabrication skills, it is an ideal addition to a media PC or HTPC. It may even suit you if your head is aching after many hours of being whined at by your hard drive."

      that's when i discovered that the noise was actually coming from the cooling funnel that sits over the CPU. the large (~90mm) exhaust fan that's attached to it was causing the plastic funnel to vibrate. i guess the hinges on the cooling funnel wore down or loosened over time so that the entire funnel unit can vibrate much more.

      I can't remember which case it is, but it should be difficult to spot from would be myth box builders.

      As someone pointed out above, it is the direct metal to metal connection from the noisy drive to the case that transfers most of the sound and the case often works as sort of an acoustic amplifier, much the way the horn on an old gramophone does, especially if some part of the case (usually one of the side panels) resonates at some (sub)harmonic of the frequency at which one of the drives is vibrating.

      In the past, I've actually solved drive vibration noise problems by the simple expedient of taking a 3.5" HD and wrapping it in enough plush carpet remnants to that it will fit snugly into a 5.25" drive bay. This will also muffle the whine of spinning disks and moving heads to some extent -- usually a lot, in my experience.

      If you look at many (most?) hard drives you will see a little hole with what looks like a filter of some sort beneath it. It is there for a reason, namely pressure changes due to weather or relocation of the drive from one altitude to another. When attempting to stifle hard drive noise, you do not want to seal this venturi by covering it with tape or a gel pack attached tighly enough to prevent the drive from "breathing"; a horrible analogy, I know, but the only better one I can think of is that the drive uses that heavily filtered venturi to equalize its internal air pressure to that of its environment much the way your ears pop (especially if you yawn) when the pressure in an airplane, tram, cable car, elevator, etc. changes significantly as you move up or down.

      Cooling fans, especially if you use a lot of them instead of more esoteric means of preventing CPUs, GPUs, and high-performance HDs from overheating, tend to make a lot of noise. Most stock cooling fans are really cheap and don't have terribly great bearings or advanced blade designs. It is often worth it to pay more for high end fans which are designed to move air efficiently (which implies more silently, if you think about it -- the energy wasted making a lot of noise is wasted energy). Blowing the dust off the fan blades every few months will make the fans quieter, too.

      Some of the Miniscribe and Microscience SCSI drives I've had in the past ran *VERY*hot...I mean hot enough that they were uncomfortable to hold for very long while or just after they'd been busy for awhile. IRRC, it was the pair of old (brand new and state-of-the-art at the time) 9GB 10,000RPM Miniscribe drives I had in one machine that died of head crashes due to heat death. An engineer I had reason to believe told me that in order to cram 10GB of capacity onto what was then a very fast SCSI drive, Miniscribe had to use platters that were so large that their edges were almost rubbing the inside of the drive case. Apparently, Miniscribe didn't take thermal expansion into consideration and one many of these drives the platters would expand enough that their edges scrapped against the inside of the drive case, creating a fine dust which would eventually find its way between the heads and the platter surfaces, causing a head crash.

      While I can't verify that explanation, it fits what I observed. One of the pair of drives was mounted directly over the other and it was from that drive I heard the distinct sounds and noticed the erratic drive performance that precede a lot of head crashes. The at drive died first in a very noisy way (I'd been making frequent made backups of both since I first heard the strange whining sounds), followed a couple of weeks later by the drive below it. The lower drive exhibited the same failure mode but died rather suddenly, unlike the upper drive which went though noisy death throes for many weeks.

      That stands to reason as the lower drive's waste heat was rising and thus increasing the temperature of the drive above it. The upper drive was used as a "data" drive while the lower one held the WinNT OS and all the software programs.

      I suppose the problem was partly my fault because I did nothing special to keep the drives cool since I had no idea they tended to run so much hotter than the lower performance drives I'd been using up to that point. Adding an extra case fan or even just a better case fan and separating the drives by an open bay might have kept them running for a long time instead of about a year or so.

      I can say one thing for sure: the sound of a 10,000RPM head crash is truly annoying, almost agonizing, especially when combined with the noise from another one that is imminent.

    Whilst I could do without the constant whine of the drive spinning, I actually like that I can hear the heads doing their thing because you can use it as another way to monitor what my system is doing. If the hdd starts making lots of noise when I don't expect it to, I want to know whats going on.

      That's a UI design issue. If there was an on-screen indication that "things are happening" or even a "magic keystroke" that overrides the normal gui and pop in and out of some kind of general system activity display in all cases where the kernel isn't frozen, then you wouldn't need to rely on design flaws of other systems to give you the necessary feedback.

      But since that doesn't really exist, at least not conveniently, I've also used the HDD noise as a valuable diagnostic tool. Now, if only I'd bought better PSU and CPU fans, I'd be able to actually hear it without straining...

  8. The catch is by Kupfernigk · · Score: 4, Interesting
    Hard drives are designed for air cooling, not conduction. That's why those little circuit boards are exposed on the outside of the drive. (Conduction cooled circuit boards do exist, especially in military systems, where expensive machined conduction plates are bonded to the upper surface, but you won't find those in commercial electronics.) Putting a gel pack on the circuit board may cool some components adequately while leaving others uncooled.

    There is a reason why Apple uses (used to use) FEA programs to design the cooling systems of their computers, and it is not marketing. In the good old days, you often found bad engineering practices in cheap PCs - such as the hard drive being screwed wrong side down to the chassis - and it was then not unusual for them to work OK as a desktop but fail quickly if used as a server, because the HDD was now actually doing some work.

      Hard drives are designed for air cooling, not conduction.

      I wouldn't say that at all. HDDs aren't designed to be completely conduction cooled, but the conduction part of it is, actually, quite important. My HDD certainly saw a serious temperature increase when I suspension mounted it, even though airflow wasn't affected.

      That was fairly easy to resolve by aiming the nearest fan more directly at it, rather than only slight incidental/perpendicular airflow.

      Suspension mounting, in combination with setting acoustic management (see hdparm) made the hard drive damn near completely silent, and it isn't going to die in less than a year due to the lack of airflow.

      That's why those little circuit boards are exposed on the outside of the drive.

      The vast majority of the heat generated by a HDD, however, is from the motor, and that most certainly is bound directly to the drive body, where the heat can be conducted away quite easily by contact with the steel case. That can make the difference between overheating, or not.

    I simply cut some pipe insulation foam in halves, and rolled both parts around the disk, one near the front side, one near the rear side. I used some electric wire around the foam to hold it in place. Now my 3"5 disk fits perfectly in a 5"25 slot in front of the case's fan, and the foam's thickness prevents it from moving. I can't hear it *at all* now, eventhough it's a SCSI 15k rpm, because the noise from the motor normally conducts through the metal and the fixations only.

    It requires very little material, skills and time to do this, and the disk can be
    extracted at any moment without hassle.
