EVGA GTX780 Coil Whine

Can anyone advise a better PSU than the Seasonic Platinum 860W to remove the Coil whine with my card?

I had Coil whine infrequently with 3DMark11. Overclockers were great with replacing my new Seasonic P860W. But the replacement now whines more, still infrequently, but with Valley this time and no 3DMark11.

I am blaming the PSU as my old Seasonic X560W didn't whine.

I've always used Seasonic so unsure as to try a third time, leave with it, or change to another brand?

Set up: i7-4770K, 16gb G.Skill Trident X, Asus Z87 Pro, EVGA GTX780 ACX and Seasonic Platinum 860W
 
Anyone?

Also can anyone advise the difference btween the GPU coil whine and the fan noises some of the ACX cards have. Difficult to tell on videos.

Coils will sound like a "frizzing to squeal" noise possibly more when the Fps are high in games menus etc

Don't know ACX fans but fans will alter the "problem noise" as you vary the fan speed.....use something to manually do this.

Noise is vibration , bigger things are going to be a deeper (lower frequency) sound that little things...good thing to remember when tracking down noise ;)
 
Thank you for the replies
I plan on trying the manual fan speed control later this week.
I also plan to change the card to see if that resolves it.
If not I'll have change the PSU again.
Might need to move from Seasonic to another brand maybe?

Seasonic makes most of the other brands high end PSU's :D

Just record the noise and post a link and I will tell you what it is ;)

The mic is on the camera/phone stick it near the source of the noise, dont keep moving it :D

That Rattling is a fan clipping a shroud ;)
But take the case cover off and get a better recording :D

oddly enough it doesn't make that sound as often with the lid off.
But I'll try get better recording

There is your answer, the cover is pushing a wire or something into a fan :rolleyes:

The Key evidence was overlooked ! :D

Post a couple of pictures with the covers off and we will narrow it down.
 
If its coil whine changing psu will not help... trust me. Don't waste anymore time or money buying new power supplies.


If its coming from the fans then I've read some complaints on the evga forum about some issue at a certain percentage with the ACX cooler. Test all fan speed % in evga precision to check if this is the cause.

There are no wires near the GPU either side.
I am thinking either Coil whine or Fan noises with the ACX cans as some others have reported on EVGA forum.
It could be repeated at the end of 3DMark11 first test with first PSU or towards the end of Valley with the second PSU. Oddly enough since change of PSU it happens more with Valley now and hardly with 3DMark11 anymore. Most commonly, infrequent and unpredictable as it is, it happens at the end of the Valley benchmark cycle where the results page shows.

I've listened to Coil whine and mine sounds louder and more screechy I think.
And with the lid off it is harder to demonstrate although it does happen. If it is the fan noise at certain rpms/temps then that would explain it as temps wouldn't reach as high.

I have a new card coming to replace the current one. I suppose that will help a lot to diagnose cause. But I will be manually revving the fans to see if I can repeat sound at will.
 
You are wasting a lot of time and money by the sound of it, just take the panels off and do another video showing around the inside of the case etc..

the noise on the second video was not coil whine, it was a slow running fan rubbing....does the new psu thermostatically control PSU fan and turn it off ?

Heres my build

PSU is the hybrid Seasonic Platinum 860W
I use in Hybrid mode. So, yes to your question

Looked at a few of the pictures, I can only see a ribbon cable across the PSU Fan, tell you what though, I don't think that ACX cooler was the best choice for that little case, it's all going to get very hot in there.

Just post that video with the top off, coil whine is not going to be so temperature linked..Fan noise is !

I can confirm that the sound is heard at 78% fan speed. Seen with Precision X on screen display fan speed percentage running Valley. Anything below and above no sound.

I tried to replicate manually. Got close to something resembling the sound at 77/78%. Not exact but close. I suspect in actual function the sound is illicit when the fan passes through 78% either way.

So the fan noise it is!

P.S. I chose the ACX as it was the best performing. Didn't think much beyond that TBH :)

It's called resonance, a product of fan balance and it's mounting design etc..

That type of cooler has no place in a little HTPC case because you just can't get the enough airflow through the case to feed its fans with cool air and extract that used heated air quick enough. If the card was running the fans at 78% I can only imagine what the temps were :eek: (they don't normally go over 35/40% until the cards are over 80c !
Personally I never run electronics over 60c if I can possibly help it.
 
I just read a couple of pages of your build log on the link you posted.... I just could not read past the bit where you Used "auto overclock" on the cpu and it was running at 100C !!!

You are a member here now so I would suggest you read and ask around these forums if you need help with cases and setups etc. etc..
