Note: Tested in RDR2 1440p High-Ultra settings. So same load on both, same testing times.
Sorry for the mess under my desk, I have very hairy legs lol.

I had some StP leftover and decided to stick it to the glass side panel cuz my foot toes always hit the glass when I'm stretching(kind of just to be sure measure), after sticking the leftover and removing a LianLi stock fan the noise dropped even further from 40 to 37-38dB as you can see in the video.

I could not make a video of them side by side, Vegas Pro crashed every single time when trying to preview the videos( I did not realise I recorded at 4K60).
youtube somehow managed to fk up the quality and display the videos as shorts.

Well, this is wrong...almost every vibration is making a sin wave in the medium (air)...so it makes a sound.

Come on dude! Are you even paying attention to what YOU say?

I said "vibration is NOT sound." Then you say that is wrong by claiming vibration is making a sin (sic) wave in the air so it makes a sound.

If something "makes" a sound, that does NOT mean it "is" sound.

If I clap my hands together, that makes a sound. Does that mean my hands are sound? Of course not.

When a tuning fork vibrates, is the tuning fork "sound"? NO!!!! It vibrates, bangs into air molecules during the process and it is those air molecules banging into the tuning fork making the sound, just like my hands clapping does.

If that tuning fork is in a vacuum, there is no sound. Why? because there are no air molecules to bang against.

Hello again, sorry for not responding for a few days. I came back to this thread after struggling to dampen the sound of my case. I used an Apple Watch Series 9 (which has a built-in decibel meter that's said to be pretty accurate) to measure the decibels before and after, and the results were quite surprising. Before, the readings were 42-44 dB, and now they've dropped to as low as 38, with a maximum of 41. Most of the time, the average is around 40 dB. Note that the tests were done in gaming(RDR2 1440p High-ultra settings). In idle, it sits around 37-38dB, sometimes even drops to 36 and that's with Arctic P12, I can't wait to get my hands on a P12 Max. Since dB use logarithmic scale, after my calculations, the improvement is roughly 37 to 60%(perceived by the human ear). Well worth it.

I used StP Biplast with a thickness of 10mm (it costs about $30-35 in my country) and some StP anti-squeak(1-2$) tape for sealing. My GPU temperature rose by 1°C, but the tradeoff is definitely worth it. I can upload some videos showing the before and after if you guys want.

Awesome... I've had a bit of success with stuffing my case with all kinds of foam, but I didn't try sound-dampening specific foam. I've plugged up all the openings though and the gaps between the GPU backplate and waterblock, but now this gives me another idea. I will get some sound dampening foam and encase the entire GPU in it, leaving holes only for the power cable and the water tubing. Will update in a few days.

 

[bobogdan625]

You should really try StP, it has sound-dampening foam for every frequency level(low, medium, high and in between them) and it's not that expensive, a sheet of 1000x750mm should be enough for a ATX chasis.

That noise seems to be fairly steady. Have you tried to localize it to determine what part of the card, or ideally, what part it's coming from?

 

[bobogdan625]

It's 100% GPU's fault, and it's the underside of it, not the chokes under the backplate. I though of buying a riser cable and mounting the GPU vertically to identify it easier but I think I'll just give up, this card is cursed and I don't want to fk around with it anymore. I'll just sell it and buy a green team GPU.

I meant what part on the card itself. Sorry, I should have been more specific.

but I think I'll just give up, this card is cursed and I don't want to fk around with it anymore. I'll just sell it and buy a green team GPU.

It's a crap-shoot either way.

 

[ad1]

If only it were so easy... my green team GPU makes yours sound like a gentle whisper. I think it's more related to the AIB and their board design and chosen components. My MSI 4090 is completely unacceptable, but I've read that newer versions are quieter. I think I'll try to stick to products with a reference board design in the future (leaning towards PNY) - I don't care about raising power limits when I'm actually running it undervolted.

 

[bobogdan625]

No one on YouTube says that AMD GPUs don't undervolt as effectively and easily as NVIDIA GPUs. I don't think it's related to the AIB; mine is a PowerColor Fighter model, which is the lowest-end option available. MSI makes good quality GPUs (except for the Ventus series). I remember watching a comparison video of the 4090 LC between the Asus 4090 Matrix and the 4090 Suprim X Liquid, and the Asus had much quieter coil whine. The temperatures were pretty equal, if I recall correctly (it was a video from Optimum). Maybe you drew the short straw; have you checked how other MSI 4090 users cope with the whine?

On Sunday, I will visit a friend who has a Focus GX850 Gold PSU. Maybe with that PSU, the coil whine on this fker will drown out completely.

Meanwhile I ordered an Arctic LF3 240mm to lower even more the CPU temperatures and maybe I can mount the old AIO on the GPU. I'm a lil bit afraid cuz of the hotspot temperatures, I don't remember exactly what hotspot measured? Was it the highest temperature of the die or was it the highest temperature on every sensor on the entire card?

Come on dude! Are you even paying attention to what YOU say?

I said "vibration is NOT sound." Then you say that is wrong by claiming vibration is making a sin (sic) wave in the air so it makes a sound.

I am not going to correct all the wrongs in previous & this post...part of it is OK, but part of it is total non-understanding...but your understanding of physics is poor! Just poor.

 

[lexluthermiester]

Gentlemen, this bickering needs to end here or the mods will be asked to intercede. Thank You.

EDIT: Nothing personal, we're getting off topic and the personal jabs are something we want to avoid.

 

[bobogdan625]

I'm back again. I did the red mod (that's supposedly what it's called), hooked up a 240mm AIO to it, and while playing RDR2 for an hour, I maxed out at 43°C on the edge, 52°C on the hotspot, and the memory reached a maximum of 82°C, if anyone reads and is thinking of buying Arctic TP3, just go ahead and buy it, it's really easy to work with it, it molds like the surface beneath it, filling any gaps and it's quite sticky too. The LF3 that I ordered is amazing, and the P12 Max (I got the better FDB version) really extracts the last bit of performance from the cooler. I'm getting 44°C on a 7600X(5425MHz @1.23V) while idling and 52-55°C during gaming. It feels like a dream come true—really quiet, without compromising on temperature.

Hi! I have a Radeon RX 6800 Red Dragon from PowerColor and it has some intense coil whine just like the card in this video. https://www.youtube.com/shorts/wvH8w48suVY

I'm wondering what would be an appropriate amount of glue to order for my card with a just couple dozen coils, I already have a 10 ml bottle of Loctite 290 but I'm not sure that is enough. There are reasonably priced Loctite glues in 20g bottles sold locally to me. Narrowed them down to 401, 402, 406 and 416 as those have a <120°C ratings. So I'd need to pick between those if I needed extra.

Attached an image with coils highlighted, not sure if anything else should be glued too. Perhaps the electrolytic capacitors, Aris from Hardware Busters mentioned those can also create noise in this video at 5:15

 

[lexluthermiester]

I already have a 10 ml bottle of Loctite 290 but I'm not sure that is enough.

That is a threadlocking compound and for metals only. See below.

LOCTITE® 290

LOCITE 290 is a medium/high strength, wicking grade threadlocking adhesive that is ideal for locking preassembled fasteners.

www.henkel-adhesives.com

Ideally, if you're going to stick with the Loctite brand, use the Loctite 411 CA glue as it's wicking action is ideal in this kind of application. The wicking action is an important aspect of the process, as such it's important to get the correct type of CA glue.

LOCTITE® 411

LOCTITE® 411 is a clear/colorless, high-viscosity instant adhesive. This general purpose, gap-filling adhesive is suitable for bonding elastomers, plastics, and metals. It is a toughened adhesive, which exhibits excellent peel strength and added heat resistance. Fixture time occurs in seconds...

As for how much to apply, follow the instructions in the first post of this thread and you'll be good. You don't want to use too much, but enough to fill any gaps.

Your highlighted photo shows all the right parts for that board. You got it exactly right.

BTW, Welcome to TPU!


NOTE to everyone:
Updated the original post with some additional info.

 

[austindroppon]

I will definitely get the 411. And the reason I suggested 290 is because it was mentioned in an earlier post (#903) with "wicking grade". I'm very glad you've clarified that, thank you for the reply!

Bought the XG27ACS (Asus monitor, 1440p, 180hz) since I saw recommendations for it.
However, it has a strange coil whine situation. It makes loud beeps (not from speakers, there are none) when switching inputs, and it has a low whine when in sleep/standby mode. I could possibly live with the intermittent former, but have had it plugged in to a switched socket to prevent the latter.
The particularly strange element is that the coil whine seems to entirely go away when it is charging something from the usb-c port. Is there some way I can use this to my advantage? It’s rather annoying to have to disable monitor sleep and have it waste electricity, or turn it off manually. Would be nice if I could discharge the electricity somehow. I thought about a usb-c power bank with led lights powered off it but that seemed a bit much.
Could still return it sometime in the next couple weeks, but monitors are such a dice roll. Who knows what problem the next one I get has.

If that was mine, I would return it and get a different brand or model. It's not like a GPU where the chances of getting one that doesn't whine are low. Most monitors don't whine.

 

[lexluthermiester]

Um, most cards don't whine, but chances of finding one that does is not zero, thus this thread. It's very rare for a display to do it however.

Personally, I don't recall ever hearing a display whine, except for older CRT monitors and their flybacks at 15KHz - obviously, that was back in the day, before Led Zeppelin, Pink Floyd, high-speed cooling fans in transmitters power amps, and military jet engines nearly destroyed my upper-end hearing!

Hallo zusammen, @ALL: Info (24.03.2024) Danke euch allen für die Informationen hier im Thread. Sucht ihr speziell Infos zu einer Karte, sind unten entsprechende Beiträge hinterlegt. (steht rechts oben, dieser ist #1) Curtains Closed - wir haben über 1000 Samples, ich klinke mich jetzt aus. Wenn...

I guess it was an exaggeration when I wrote most whine, but I'd say a fair chunk does. I've seen posts from someone going through like 10 4090's trying to find one that doesn't whine, only to end up keeping the one that whines the least. My point is the same, finding a monitor that doesn't whine should be so easy that you shouldn't end up keeping a whining one if you can return it.

 

[Ando]

I've ordered the MAG 274QRF QD E2 to replace it. I contacted the seller about a return but they have yet to respond, despite claiming to do so within 24 hours :/
I may end up just giving it away or selling it myself. Lesson learned to buy direct from amazon or a more reputable seller.

I agree this doesn't seem to be a usual issue for monitors. It seems to be an issue with this particular monitor, not just my panel, since I found 2 separate reviews mentioning it. They only mention the loud input change sound, and indicate they don't hear it in standby like I do. It is much quieter, so they may not have noticed it (I'm pretty sensitive to this sort of thing). Or I just got a particularly bad unit. Either way, buyer beware for this monitor.

965 out how many millions that have been made? I'm not saying it doesn't happen, because it does, thus this thread. But it's not as common as people think. I'm going to leave it at that thought.

 

[Bill_Bright]

I'll say this then leave it at that.

The 965 samples in that link is the number of samples (cards) evaluated. It is not the number of samples that whined - meaning the number is even lower than 965.Also, it seems they are including "squeaks" and "rattles" in those numbers meaning the number of cards with coils that whine is lower still.

I guess it was an exaggeration when I wrote most whine, but I'd say a fair chunk does.

Fair chunk? Yeah, that sure is an objective number that accurately defines the problem.

Exaggeration? I'd say blown totally out of proportion! And I quickly add, that is NOT pointing fingers at you specifically. But rather at wannabe IT journalists who fail to do their due diligence in researching the extent of problems, and simply parrot reports.

But it's not as common as people think.

Right. The problem is, like so many things, one person reports a problem in a post on the Internet. Five people repeat that one report of that problem. Then five more repeat those 5 repeated reports. Now you have 25 repeats of the single report. Before long, it is 125, then 625, then 3,125. And in some cases, that's just in the first hour (minutes??) after the initial report!

Another example I like to use is Toyotas in similar scenarios. If you walk into a Toyota service center, you will see "a fair chunk" of Toyotas in need of service. Does that mean most Toyotas are always in need of maintenance and Toyotas are lousy cars? Of course not.

The truth is, most coils have the potential to whine. HOWEVER, whether that is audible or not is dependent on many factors, including construction and mounting but perhaps most importantly, the frequency at which they whine. Today's latest PSUs "switch" at much higher frequencies well above the hearing range of us mere humans. And I note the trend is in increasing that switching frequency as it results in better regulation of the output.

Higher frequencies in switching PSUs also allows for smaller components. You are much more likely to hear a murder hornet buzzing around your head than a gnat.

I didn't actually read that article. I was quoting the comment. No worries. Of course, to your point, that further supports the notion that it is uncommon.

Excellent point. Most choke coils do have some level of naturally occurring vibrational resonance to them...

[ad1]

It's not even an article, it's a survey which ran for 1.5 years on a popular German forum. The results are summarized in some tables in the first post. It's not wanna-be IT journalists, it's forum members sharing their experiences with their 40-series GPUs.

For example...
MSI Suprim X 4090 cards, 33/45 owners reported annoying whine or rattle.
ASUS TUF 4080, 18/18 owners reported annoying whine or rattle.
In contrast, Zotac 4090 AMP Extreme AIRO cards, only 4/48 reported annoying whine/rattle.

You guys make it sound like you'd have to be extremely unlucky to get a whining GPU, but actually, if you have an MSI Suprim X 4090 or an ASUS TUF 4080 manufactured around the time that this survey ran, I think you'd have to be pretty lucky to get one that DOESN'T whine.

But yes, my statement was in fact an exaggeration and blown out of proportion, I should not have overgeneralized and made the claim that most GPUs whine.
