Coil whine issue - Not solved - tried 4 different PSU's

[markel00000f]

Hey forum.
I am new to this forum, i registered since i couldnt manage to get the problem fixed by talking to the reseller or to swedish forums.

I have tried these different PSU:s:


Corsair TX 650w
XFX Pro Series 850w
Fractal Design Newton r2 1000w
Cougar CM 1000w


And i've got this horrible coil whine whenever i run a benchmarking program,
starting a game and comes to the menu screen, and also when the fps is high. I got the problem fixed by turning v-sync on, but since im using crossfire and since i've always played without v-sync (and wants to keep on doing it)
this is not an acceptable solution for me.


I have also tried to change keyboard, mice and also switched to a SSD hard drive instead of the old mechanic ones, and the problem is still there.

I have also switched graphic cards from:

GT 240
GTX 470
GTX 470 (another one)
6870
6870 BE

And the problem has been there with all these different graphics card.

I have also tried the computer at friends houses to see if the problem was in the connection into the computer, but no, sampe problem no matter where i run it from. I have also tried to run it outside the case and in a different case and the problem is still there. I have also changed the memory sticks.

The only thing i havent changed is the motherboard, but is it really that big of a chance that the motherboard is causing all this?

This is my rig for the moment:


i5 760
6870 BE
4GB ram (Corsair)
Cougar CM 1000w
GA-P55a-Ud4



If i ever find a solution to this problem i will personally give the guy who helps me fixes this a gift, the gift is my steam account with Black ops, MW2 and some other really cool games (which i dont like to play anymore).


Thanks for any answers that can help me and have a great day.

I'm not sure exactly what you mean by "coil whine," but have you opened the case while the machine is running to check whether the fan on your CPU cooler is making the noise?

Hope that helps.

In the same vein as the "CPU fan", go into bios and just set all the fans to max cooling under any circumstance (In other words whatever the bios calls it). This is just make absolutely sure that it is not some fan, any fan.

Just go to Youtube and search for coil whine and you see.
For example;

0:50 on this video, for example.

It's a hig buzzing noise, and yes, it's the PSU making the noice, and yes, the machine is opened and i've also taken out the psu from it and yes, 100 % the PSU.

Read my reply to Harvey.
It's not any fans, it comes from the PSU.

You didn't say whether you've tried a different PSU or another in the other case. If it's the same, and the whine happens under load, it could be caused by internal arcing or shorting in some component in the PSU, such as a transformer, inductor, capacitor or the PSU's fan motor.

I have tried all four different PSU:s both in the case, in another case and outside the case, such as in different houses.

And therefore, how come the problem isnt fixed by changing between 4 different PSU's, such as 4 different graphic cards?

And yes, the problem comes whenever i have v-sync off and running a game, or in the game menu.

And yes, the sound is exactly the same in all of the 4 different PSU's.

I can not believe that I had 4 different PSU's making this noise--


This leads to my next question, can this issue be fixed by changing motherboard?

 

[markel00000f]

have also noticed i have to have C-state support off because otherwise i can hear coil whine everytime i newly start the computer and when its not under heavily load, so
there is another reason to switch mobo, or what do you say?

r c1/c3 state support and EIS is the options i cant have ON, and have to turn them off to not hear the coil whine during NOT heavily loading.

So, switch mobo perhaps?


And the graphic cards has been changed, and from what I can hear the noise is coming from the PSU, same noise from all four different PSU's, and same noise from all 4 different graphic cards.


So is changing mobo maybe the solution ?

I'm an electronic design engineer, and I can't believe it, either.

If that's the only component you haven't changed, yet, that sounds like an extrapolation of Sherlock Holmes' maxim:

When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

The only way to find out is to test the theory. It would be nice if you could use another copy of the same board so you could use the installation on your hard drive.

Read my latest reply, dont want to spam replies but read the latest one i writted about c-state support...

Do you want an engraved invitation to change the motherboard? Listen to Sherlock (Harvey, I had the EXACT same thought after reading the OP ). Since that's pretty much the only thing you haven't tried, why are you NOT trying it?

I had the same issue with Core is/750, Gigabyte P55 UDR3, Corsair TX 650, EVGA GTX 460 1GB.

My CPU was mildy OC'd (160 bclk) and the PSU would WHINE LOUDLY in WOW and moving the mouse cursor made the PSU whine, too.

Setting the CPU to stock would mostly fix the issue. I wasn't happy with that. On a whim, I flashed the BIOS because the new version "Improved turbo compatibility" and I knew then and there that my CPU hitting turbo in WOW was causing the PSU to WHINE.

The BIOS flash fixed the PSU whine 100%. Can't hear the mouse now, either. I don't have turbo now, but I've got the CPU set to 3.4 GHz and all is silent on the PSU front. Even in WoW.

Try flashing the BIOS starting with the most recent and working backwards until the PSU stops complaining.

 

[Tsavo]

Also, I tried all the other fixes like disabling C1E and EIST. Those did nothing for me.

If you switch motherboards to test, be sure it's a different manufacturer (i.e. no gigabyte).

Also, are you getting "mouse whine" as well? Logitech mouse?

I have tried ALL different BIOS versions now, F10 to F15 and same problems with all.

I will try with a new motherboard, not from gigabyte, from MSI.
The P55A-G55.


and no mouse whine.

 

[Rifter]

I would change the mobo. You already changed everything else so why not.

sounds like some bad grounding going on. i had this one motherboard it outputs sound (radio) to the speakers when its idle very lightly. move the speakers to any other machine and dead quiet. the sound card is built in. i figure a cap or something has leaked out and done some sort of damage.

The facilities that makes these boards have giant pincushion devices that can test in a second every component and locate the fault. obviously this precision costs alot but i'd just rma the component that seems to cause it.


Have you tried a puresine power supply on battery or a double-conversion (SMT apc) ? just to make sure you don't have dirty power. Standby ups allow dirty power through even on high sensitivity and modified square wave is really dirty too.

I'd borrow a friends double conversion (or take it to your buddy who works in a noc its all double converted or flywheel clean power).

 

[markel00000f]

The electricion is fine, my dad works like a what do u call it, electrician man?
well, if the new motherboard im gonna pick up in 1 hour does not solve the issue, then i have tried everything. what then? Im pretty sure the most people can have v-sync off and dont get the coil whine, so why do i get it even though i change out everythng``?

 

[markel00000f]

Tried with new motherboard now, no change.


What now?
I have switched all parts in the computer and i have also tried in different houses to make sure its not a electricity problem.

 

[deimos3428]

1. If you have speakers, try removing them from your system to see if there is any effect. Could be a grounding loop or some other output that just sounds like coil whine.

2. Form a cone out of a sheet of paper and use it to attempt to isolate the source of the whine. If you know exactly where the sound is coming from, that's usually the component you need to replace.

3. Other than that, you seem to have enough spare parts to build another computer in its entirety...sometimes it's easier to just rebuild from the ground up. Get it functional, then steal parts from the whiny one until it starts acting up.

 

[markel00000f]

Hey.
I just tried one game.


In the menu i had like 350 fps and in the game i had like 60-80


This time it didnt whine at all.
seems like it starts to whine when it gets up to 1000 fps...


and like i said, i have switched graphic cards, from gt 240 to gtx 470 to another gtx 470 to a 6870 to another 6870
and PSU's from corsair tx 650w to xfx 850w to fractal design 1000w and now cougar cm 1000w.

now it said poff and then it were all dead
