Pretty much as the title says it I have this laptop for about months, and this annoying low frequency sound started like a month ago. After reading a bit on the internet im pretty sure that it is coil whine, its coming from the WASD area of the laptop and it is annoying af. I sent the laptop to a repair center and after 2 weeks they returned It to me with changed fans and motherboard, and guess what It is there no matter if the laptop is plugged in or not, I also have the latest version of bios - Any ideas how to proceed from nowshould I just send It again and spam asus support with emails or what is the best option to do?
So nobody with ROG laptop has experienced a coil whine? You have already done what would have been suggested to do, return laptop for repair.
I believe the only recourse you now have, is demand your money back. Good Luck. Nope, never had a laptop with coil whine, you are the first time Ive heard of it. I have the GGV and I also have the coil whine nonstop. I run the laptop in silent mode to reduce it so that I don't hear it anymore unless I put my ears over the keyboard.
The faster the CPU, and the more the turbo is active, the higher the coil whine. I put my ears over the Alienware 17R2 that I have and I also hear it but it's very faint. My wife's Dell laptop also has it but also very faint. This and MSI laptops have it loud. Sometimes, the coil whine goes away though. I am unsure of the cause.

Change language. Install Steam. I know this isn't really the right forum to ask, but I thought I'd ask anyway. So I have this fairly loud high-pitched buzzing sound coming from around the CPU area of my motherboard. It is more of an electric kind of sound than a mechanical one. Interestingly, the buzzing stops when I perform intensive tasks, such as gaming, and even moving the mouse around a bit causes the noise to become quieter. It's nothing to do with my CPU fan as I have replaced it recently and the sound persists.
Also, it's not my GPU as I also recently replaced it for an unrelated reason and I still have the buzzing. I'm not ruling out my power supply, but I'm fairly sure the sound is coming from my motherboard.
FAQ: Coil Whine
Is this sound dangerous and does it indicate a dying component? I can't tell how long the buzzing has been going on, but I only really took notice of it recently. Any help would be greatly appreciated. Showing 1 - 15 of 46 comments.
If you're worried about it and you know it's the motherboard, contact the manufacturer before the warranty runs out. They may replace it. Use it against your ear to detect the location. Is it the PSU? The fans? The CPU?Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles.
Everything you need to know about coil whine
Most of the time our AC adapters and power supplies tend to be quiet, but what does it mean when one makes a whining noise? Should you be concerned? Photo courtesy of Bart Everson Flickr. SuperUser reader Rishat Muhametshin wants to know why some of his AC adapters and power supplies make a whining noise:.
However, I often hear a whining noise from some of these power supplies. This happens most often when they are not connected to a device or otherwise in use, and stop making noise when I connect a device that is not fully charged.
Why do some AC adapters and power supplies make this whining noise? Why do some not make this noise? Is there anything that I can do to suppress it? First up, DragonLord:. Most power conversion devices contains coils, such as transformers or inductors. These components use electromagnetism to convert AC main power to low-voltage DC power.
The varying magnetic fields generated by these components can cause them to physically vibrate at high frequency, resulting in a high-pitched noise.
Most modern AC adapters are switched-mode power supplies. The internal switching frequency of an SMPS is typically low when unloaded and increases with a load up to a certain point depending on the design. The no-load frequency is often low enough to be within the human hearing range. Together, these can lead to audible noise especially in cheaper units which fail to suppress this noise. Under a load, a properly functioning SMPS should operate at a frequency well above the human hearing range, typically 50 KHz or higher although some older designs operate at 33 kHz.
However, the same noise can occur under a load with a poorly designed or defective power supply as the coils may vibrate under electrical stress at a sub-harmonic frequency. The glue helps reduce the vibration and noise the coils generate during normal operation. Of course, this means that a user can apply glue onto coils using a glue gun to suppress coil whine—and yes, people have done this successfully with PC motherboards, graphics cards, and power supplies.
However, you generally cannot do this easily on small wall chargers of the sort you mentioned without risking damage to the charger or exposure to potentially dangerous voltages. In conclusion, a whining noise is not necessarily a sign of trouble in cheaper wall chargers when they are unloaded. However, a computer PSU or laptop charger that generates coil noise, especially when under a load, may be defective and you may want to consider replacing it.
More information on coil noise can be found in this Wikipedia article. As the magnetic field increases and decreases generally about a thousand times a secondthe force of the field causes the dimensions of the coil to change slightly, and this vibration leads to a whining sound.
Even the wires on a printed circuit board can whine slightly under the right circumstances. Have something to add to the explanation? Sound off in the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

When you hear a high-pitched sound from your computer, there's no reason to assume that your computer is toast, that your hard drive is about to die, or anything like that.
In fact, this high-pitched noise is really nothing more than an annoyance. Coil whine is a high-pitched sound some devices inside the computer case can create under certain situations. This hiss or squeal resembles a dull, boiling teapot sound, only usually much quieter. These coils in your computer have an electrical current passing through them, one that normally fluctuates, which is what the coil is there for: to try to stabilize the current to provide a more regular stream of power.
When the electrical current is increased to a certain point, the magnetic field around the coil can cause it to vibrate, which produces the whiny sound. Not only is the loudness of the whine dependent on the person hearing it, it also matters how much electricity is moving through the wiring and, of course, the distance the computer is from your ears!
Another way is to use a benchmark tool to test specific hardware and then, again, listen for when the noise is actually produced. If you're having troubles, you might need to hold a straw from your ear next to various components in your computer to help isolate the sound. Just please be careful when you do this!
However, be careful to not confuse other noises — like pops, rattles, or clicks — for high-pitched sounds and just assume it's coil whine and walk away without addressing it. For example, a squealing noise might at first seem like coil whine but it could actually be noise from the hard drive pointing to a failing HDD, and another sound might more accurately be a sign of a rapidly overheating power supply.
Even if the noise isn't coil whine, it doesn't mean that whatever it is is causing a problem. For example, if your computer makes a noise each time you're doing something like burning a movie to a disc or ripping music from a CD, that's just the optical disc drive — it's normal to hear the disc spin.
In other words, it's important to listen for the distinct hissing that most likely means the problem is with a vibrating coil, in which case it can be called coil whine and you can address it as such. You might even experience a high-pitched noise when the computer is off!
This is most likely an issue with the power supply. Something you can try in that situation is replacing the power cord with one that features a ferrite bead. There are multiple things you can try to reduce the effects of coil whine, from addressing the wiring directly to buying or building a computer made specifically to absorb noise, but those are the more drastic solutions.
Move your computer further away from you! This will obviously only be beneficial to people who have their computer on their desk, right next to them all the time.
Put it on a piece of wood or a lower shelf on your desk, if you have one. Blow out your computer. Open the case and use canned air to remove dust and other grime from any fans and other equipment. When these components, especially fans, collect enough dust that it slows down how they work, it can force them to run faster to make up for it, which is going to demand more power and thus produce more noise like coil whine.Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles.
On a pure technical level, coil whine refers to an undesirable noise emitted by an electronic component vibrating as power runs through an electrical cable. In bad cases, you can actually hear the pitch of the coil whine change as the GPU draws more or less power, and the electrical frequency across various components shifts.
It might be particularly noticeable when running a 3D game or high-intensity graphics application. Coil whine can be especially noticeable—not to mention frustrating! Coil whine is really nothing to be concerned about.My 91yr Grandpa Meets Google
The fixes for the problem, therefore, are going to be physical in nature. You have a few options.
Dampen it. If your PC is making too much noise, trap it inside the case.
What is Coil Whine?
Different PC enclosures have different audio properties, and some manufacturers make their cases specifically to dampen sound and vibration. Generally speaking, a case with more dampening material, like high-density foam or fabric, will be better than bare steel or aluminum at hiding noise levels. Keep in mind that moving your entire PC to a new case is a time-consuming processbut not a particularly difficult one if you already know how to swap out a graphics card or RAM.
Replace it. If you can pinpoint which part is causing the whine you could just replace it. Unfortunately, coil whine alone might not be enough for your graphics card or power supply maker to accept a warranty replacement —and it may not be worth hundreds of dollars for you to replace the part.

Skip to content.You turn on your PC, start up a particularly taxing program, and then—you hear it. A high-pitched sound emanating from somewhere as if your ears are ringing. You're not going crazy, it's coil whine, and it can come from a number of components in your computer. Coil whine, as Linus from Techquickie's YouTube channel explains, is a phenomenon found in a lot of technology today, but especially in video cards. It usually occurs when a component is working really hard and begins to vibrate, emitting a high-pitched noise in the process.
This is pretty common when playing games as they tax your video card the most for substantial lengths of time. Additionally, games or other graphic intensive software will tax your video card at different levels, causing a variety of high pitched sounds to occur.
If you're playing or working with speakers or certain kinds of headphones, it could become pretty annoying. What can you do?
Well, the unfortunate truth is that once you've got it, you can't really get rid of it. Your best bet is to prevent it in the first place by reading reviews and researching which products tend to have the most coil whine. So before you jump into buying that delicious new video card, be sure to check that it doesn't also come with some distracting coil whine on the side. The A. Shop Subscribe. Read on.

My Ti an evga FTW card also had some coil whine, but the fans were also a lot louder when gaming on that card so I wouldn't hear it much unless it was a menu running at like fps or something like that.
My 's fans are far far quieter than my Ti, but that means I can hear some faint coil whine in games now most notably Witcher 3 which I hit around fps on.
Anyway I guess I'm asking for any suggestions on how to reduce the coil whine, or should I just exchange it? I may try a new PSU, mine is a Corsair which I think are supposed to be pretty good still, but it's also kinda old so I figured it's worth a try. I may also try insulating the sound from my case a bit, I have a corsair cube case and the dust filters on the top and front of the case are pretty open, I ordered some foam sheets to see if they would block sound a little more without messing with the airflow too much.
Does anyone have recommendations for power supplies to try? From looking around it seems like Corsair and Seasonic are still popular companies, I was hoping there was a newer company putting out really high quality stuff like PC Power and Cooling used to do but it didn't seem like it.
VirtualLarry Lifer. Aug 25, 47, 4, I must be extremely lucky, or perhaps, my ears just aren't sensitive to those frequencies anymore, because I have yet to actually really experience any "Coil whine", either GPU VRM-based, or mobo VRM-based technically, it's the coils, not the solid-state VRM parts.
Or maybe, I just choose cards with solid chokes, and whatnot. I also run fans around the apt. Edit: So, I guess, I'm sorry that you're experiencing this. I have no experience with the issue, so have nothing to suggest. Other than maybe get some silicon "goop" and try to stabilize the coils with it, maybe?
I'll have to check out the video card to see what kind of inductors are on there, I'm pretty positive it's my video card since the noise disappears when I exit a game.
Honestly it's not too bad, my PC is so quiet now that it's just more noticeable than with my previous card. RetroZombie Senior member.
