SPCR is starting a project to explore solutions for electronic whining noise from video cards, motherboards, power supplies and other computer components. We seek participation from our community. You can help by donating products exhibiting high pitched noise that bothers you. We will examine these products and try to determine the sources and reasons for the noise, then explore different ways to eliminate or reduce the noise.

Send us only products that you don't mind ever seeing again. The product could become inoperative in the course of our investigations and end up in recycling. On the other hand, if we succeed in reducing or eliminating the noise, we will let you know and give you the option of paying for the shipping to get the now-quieter unit back for you to use and enjoy.

For the sake of relevance and usefulness, please donate only products that are not older than ~2 yrs. Higher power/efficiency devices are most interesting, because in general, these are the kinds of products that seem to exhibit more electronic noise, more often; they generally tend to be newer. If you have any doubts or questions about whether the product(s) you're thinking of donating for the project are suitable, please post your queries here.

The results of this project will be published as an article, documenting our experiences, and hopefully, a how-to DIY guide on how to reduce or eliminate electronic noise in these computer components. Target completion date is 6~8 weeks, but this depends a lot on your responses. We certainly will not have enough data/experience with fewer than ~20 samples; this is my arbitrary minimum number for article/guide publication.

Local contributors may drop their whining components off directly. For details, please contact me by email -- mikec at silentpcreview dot com

I have an OCZ Z series 550W power supply which whine at medium-high loads; I can loan it for these experiments, since it is in spare status. I live in New Westminster, so I can drop it off personally. As contact: use the board PM or e-mail.

I don't have any spare parts yet, but would probably donate a bit if you'd be looking into the high pitched whining noice of the Seasonic X power supplies.

If you're still accepting samples I may have a Corsair Builder CX430 (v1) that has pretty bad coil whine when plugged in with the system off. As far as I know, the more recent V2 also has the same problem.

This initiative has seen such a lackluster response that it has to be considered dead. No interest, no point.

Sorry - no whiny spare hardware here.

This would have been a cool project.

Too bad, though I think it was some 6-7 years since last I had a problem at home with a whining system component. I suspect the power lines around here are simply too good to induce the problem by putting the little extra stress on otherwise good components. I part time in a store and mostly notice that kind of noise from low budget laptops nowadays.

Damn... if only I lived closer... Like... on the same continent

I want to say bravo to Mike for coming up with this project.

I haven't had any whistling/whining electronics in some time (touch wood), and most of that was associated with CRTs. I do remember reading some where about whining SSDs and other cases of PSU coil whine being induced by SSDs.

Needless to say, I eagerly await your results.

Are you interested at all in mouses? I ahve a couple logitech mouses that produce a high frequency whine that aggravates my tinnitus.

This aught to be very interesting. SPCR might identify patterns of noise generation that have been and are being overlooked by manufacturers... just because they present themselves in what appears to be an erratic manner.

Three things you could investigate:

1) Any Core i7 (possibly i5) with C-state support enabled -- specifically, C-state transitioning between C3/C6.

On every Core i7 system I have (one HP laptop (not sure which rev/stepping), and one desktop (i7-2600K, rev D2 / stepping 7)), I have to turn this feature off, simply because the transition between the two CPU sleep states is audible. Yeah, even within a Fractal Design R3 case I can still hear the CPU transitioning between the two. I solve the problem on my laptop using ThrottleStop (since the HP system BIOS offers no way to disable C3/C6), and I solve the problem on my desktop using the system BIOS. Lenovo laptops (which I also use at work) have the same problem, but offer the disable feature via the BIOS.

I should note this noise isn't audible to a lot of people, but is to some others. In fact, at work (where my laptop is) most of my colleagues can't hear the noise. There's only one other than me who can hear it -- and only after I pointed it out to him and asked him to listen closely (he's also a musician, heh). Now it drives him just as crazy as it does me.

Here's a Youtube video which exhibits the problem. Just search Google for "Core i7 c3 c6 high pitch" and you'll find lots of hits.

This is a pretty well-known problem, but it's also pretty low-level. Good luck on getting this one fixed; will require getting past a lot of red tape with Intel.

2) The infamous "siren" coming from PSUs when using tools like ATITool "spinning cube".

Happens with ATI cards or nVidia cards.

Supposedly MSI was one of the companies who addressed this problem, but I own a MSI N560GTX-TI Twin Frozr II and it has this issue. PSU is a Corsair Professional Series Gold AX850. Same happened using an Antec PSU.

So it seems to me that MSI at one time cared about this problem, fixed it (yay!), but then forgot it was occurring and now we're back at square one. What's amusing is that the GTX 200 series came out in roughly 2008/2009, and it's now 2012. So in only a few years they forgot.

They aren't the only one either. Google for something like "video card frequency noise" and be amazed.

3) Logitech mice.

I have been tracking this problem with their mice since 2004, and finally in 2011 a hardware engineer (just a random guy off the Internet) contacted me and told me what the problem was, as well as the details/harmonics involving why it happens. The issue is caused by ceramic capacitors. Simply replacing them with tantalum caps solves the problem. This issue has also begun to affect certain models of Microsoft mice.

I would LOVE if you would really drill Logitech on this one, hard core. As I said, I've been trying to get it solved for EIGHT YEARS.

Finally, and I'm going to bold this, because so many people respond to posts of mine like this with "I have Product X and I don't hear what you're talking about": it all depends on the level of sensitivity of one's hearing. I happen to have extremely sensitive ears and quite a large frequency range is audible to me (a colleague of mine used a software tone generator to generate frequencies of pulse/square waves to see where my limit was -- it's something like 8-9kHz higher than the average person). So please do not state something ignorant like the above. This ignorance is exactly why these products emit noise to begin with: the person designing them and the persons QA'ing have normal or sub-par hearing.

Thanks.

Shoot - I knew I should have kept my noisy components instead of getting rid of them ASAP.

I sign koitsu's statement on sensitivity, and can attest to the Logitech mouse whine problem. I've heard it too, and it's not pleasant. If I come across any samples, I'll be sure to send them SPCR's way.

Any chance of reviving this project? I'm wondering if it would be possible to at least compile a list of configurations that whine from the forum and see what patterns emerge. I'm seeing some anecdotal reports of whining video cards or PSUs here and there on the forum, but it's scattered.

Ok, I just shut off speedstep and C1 whatever in the BIOS! That fixed it! No more headache!

By the way; very sad for the "other" environment (not my ears environment that is) that power reduction produces high frequency noise!

It's the fact that the power consumption changes rapidly many times in a short interval, as CPUs can go to sleep and wake up very quickly. In some power supplies this leads to whines and buzzes.

No, it's the speedstep transform to lowvolt that causes it (when you put the CPU under load the noise dissappears and it definetly comes from the CPU or really near the CPU and not the PSU)... I'm not talking about buzzing, but high pitch/freqency sqeaking like dog whistle.

Few hear this because they have "bad" hearing and case + fan muffles it.

I run my PC with the case open and with a super silent CPU fan, also hearing is a bit too god...
