How to quickly & easily fix coil-whine(coil choke noise)

[lexluthermiester]

Anyhow, can someone confirm the glue I've listed is good for the job, or can recommend to me the best glue possible? Thanks.

Where in the world are you? If you're Stateside, Harbor Freight's generic super glue is perfect.

WOW a reply from the master himself, I'm honoured.

Completely the opposite, sadly..

EU? Or did you mean South America? Either way, the "SuperGlue" branded tubes will also work perfectly. Even the CrazyGlue brand will work as long as you get the liquid. Stay away from the gel form.

Oh, so is this to say that the one I currently bought is not a viable option? Damn.

It looked good with the high flow it stated, as I read 'wicking' was an essential part.

Show us a picture or link and I'll give you a thumbs up or down.

If what you have states high-flow, you're very likely going to be ok.

I'm familiar with that brand, good stuff, you're golden!

Holy shit that's a huge relief to hear, thank you so much. I'll certainly be sharing my results when I receive the new unit, ASSUMING it'll have Coil Whine, ha.

Few questions however, I'm not sure if it's just because I've used some cheap chinese glue or something, but most of the time when I use the stuff that I buy from a discount store, the glue becomes white and flakey at times?

Is that because it's just not quality stuff, or did I accidentally buy the gel version? It seemed quite runny and liquid-like?

Also, how certain is it that this glue I've purchased can withstand the temperatures the VRM pumps out? Example 100*C and the heat cycling?

Is it safe to say even if the glue does deteriorate, it's not anything to worry about given it's non conductive, and it'll simply be a clean n' reapply situation in the distant future?

Would it have been better to buy an electrical varnish instead? Can't imagine that'd actually wick into places as effectively though..

That is a curing thing. Not sure what causes it, but it's just surface crystallization thing. It has no effect on the viability or functionality of the glue. My theory is it's an over-oxidation effect due to variations in the formulation at the factory, but that just a theory.

No, and it won't. Tried it years ago. Never succeeded with it. It would be great if it did, but sadly...

Makes total sense yes, crystalisation which is making it look white and cloudy. Definitely wanted more quality stuff though like the Zap Glue I just received. Thank you again so much for all this! Can't wait to give it a go.

OFCOURSE... I wondered why when I store my superglue in a ziplock bag and toss it in the fridge, the bag kept getting all frosty and mottled white.

So the simple answer is to just park the project next to a gentle blowing fan. Too easy.

Excellent article! There are a few things there I didn't know about the subject.

For the application being employed on GPU's, it's really not an issue and will not affect the outcome.

Well, it would be nice to make it look discreet, almost non existant.. for warranty purposes. ';d

 

[Simone]

Well, everything came early.. just to clarify what exactly am I gluing, just to be sure..?

Um, can you attach them directly to your post? Not seeing anything. Imgur isn't a great image hosting site..

@Wolverine2349
unless you remove all paint down to bare metal of the psu, there is no "ground" connection to the pc case by touching,
so using silicon/rubber pads isnt an issue.

Yes, my monitor supports G-Sync and it's always enabled. I only turn it off when I do benchmarks.

dad gum. just did an rtx demo and have horrible LF coil whine while synced 60.
but it only happens with DLSS enabled.

Hey Lex, I apologise. Will this do?

 

[lexluthermiester]

Ah yes, that'll do and here you go. The rows you highlighted are important, however in laptops the board chokes can be the problem as well.

 

[Simone]

Thanks Lex, what about here? This is the opposite side of the motherboard.. if I am correct, the CPU on left, and the GPU on right.

Those are capacitors, not choke coils. They will produce no noise at all.

Thought so. Just making sure. Thanks. Welp.. time to put the board back olol ;d

At least I discovered there’s NOT any coils there. :3

 

[Shrek]

Just for fun, not to contradict anyone, but it seems some capacitors can be noisy.

Why does acoustic noise occur in ceramic capacitors, and does this have any effect on reliability? | Capacitors FAQ | Murata Manufacturing Co., Ltd.

Shit.. it's true. Hopefully only the ceramic ones.. I DO SWEAR though when I took the bottom off my laptop, it STILL sounded louder coming through the keyboard side and not the open side where the heatsink and everything was visible.

COULD still be those stupid chip capacitors.

Once everything dries, going to test and see if it is fixed. It is curing quite slowly. I put a gentle fan on it to try avoid the crystalisation.

The wicking certainly did happen though wow. I added the glue to one side, and I watched closely, eventually it started coming out the other side from under the chip. Hopefully it climbed in and filled voids, too.

Can't wait.
