System High Pitched Noise

[stan92]

hi all, I just built a gaming rig for myself, and ive noticed that i can hear a high pitched whining noise, I've located the sound to be coming from the CPU area. Can anyone please help me? I have a sound clip on my computer that i recorded with my phone. I can email it to anyone that may be able to help (if needed).

What motherboard are you using? It sound like coil whine to me.

[Samdb]

It's most likely coil whine, there is unfortunately nothing you can do about this.

[tp95112]

Are you using a stock heatsink thats probably why

[Overl0rd]

Yeah, most likely coil whine. You can try RMA'ing it if it's really obnoxious.

I know this sounds bad but i bought a second hand ASUS P8H61 M LE USB3 motherboard when i built this rig a few weeks ago, which worked for a few weeks but sometimes the computer wouldn't turn on, then eventually i had no display and keyboard and mouse. I just bought a new ASUS P8H61MX USB3 motherboard brand new and it works perfectly apart from i can still hear this whine. I probably should add that the sound sometimes gets louder when I'm in a game (not at loading screens) only when rendering/using furmark to benchmark.

Ive also pulled my power supply out and ran the computer with it out of case, and their was no noise coming from the power supply. Same with my ATI HD7770 i pulled that out and the noise was still their.

[stan92]

Yes im using the stock intel cpu cooler.

Coil whine ususally gets louder the more stress you put on certain components. You say the whine comes from the CPu area, so I am assuming the whine gets louder the more stress the CPU power delivery is under

Does the whining sound like the graphics card in this video? If so, try to RMA the thing if it's really that bothersome for you.

so your saying the VRM has capacitor coil whine? even though this motherboard is brand new?

Unfortunatly that is possible. Coil whine is a normal part of some products and is not considered a fault.

[stan92]

wow so probably as this and my previous motherboard is a 'cheaper motherboard' as its only a p8 h61 not a z77 board they all may have coil whine as they are cheapish? also should i be worried about the vrm whining?

The cheapness factor does play a apart, but not 100%. I have worked with high-end x79 boards that had terrible coil whine aswell. 

No, coil whine is normal. The only thing it is is annoying.

0s4x : that coil whine is changing in pitch and loudness whereas myne is steady and then in game sometimes gets louder but once it goes up either louder or changes frequency it stays like that until i either alt tab or quit the game.
 

 

Volbet : ok  thanks also anyone know why my old board ended up not giving power to mouse keyboard and monitor?

If it was used you should try and clear the CMOS. Also the board could have been faulty, but it doesn't sound like it

[stan92]

did clear cmos and done nothing, all the fans and leds were working though... i find it very bad luck that ive had two motherboards both with coil whine (in a row)  :(

[stan92]

how common is VRM coil whine?

[Volbet]

how common is VRM coil whine?

It is not that uncommon. You do encounter it on some graphics cards and on some motherboards. I have even tried having a NIC that coil whinned. Unfortuantly manufactures sometimes cheapen out on the power delivery componants and then they produce coil whine. 

[stan92]

ok so about 50% of the time manufacturers (in this case ASUS) stinge on the cpu power delivery. Also is it true that some people cannot hear it?

As people age their hearing usually degrades. this means they have a smaller field of sound frequencys they can react on. Short answer: Yes, some people might not be able to hear it, since the sound is high in frequency

[stan92]

ok, thanks, so could we say that approximately 50% of the time manufacturers (in this case ASUS) 'stinge' on their cpu power delivery causing interference/coil whine even on new boards?

[stan92]

?

I don't know of an exact percentage. I always recommend looking up reviews of computer part before buying them. This is so you can avoid things like coil whine or bad power delivery. You also have to consider that motherboards consists of a lot of different chips manufactured by different companies. An Asus board might contain chips from Marvell, Foxconn and Realtek just to name a few. Also the componants that make up the power delivery is most likely not made by Asus, it's only the overall design that is made by them.

[stan92]

Ok. So approximately from what you have observed with motherboards (mainly asus) how much percent would you say had bad power delivery?
