Ah yes, the 7-slot graphics card.

ME: thinks it going to be super quiet Coil Whine: REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

Let the fan sit out side the case like a Hot Rod engine.

I've never seen a dude smile so much.... You go dude! I wish my wife would look at me the way you look at this Graphics Card Mod.

That 3 fan version sounds like a jet engine, but those temps are ridiculous.

can you do this again with a 2080ti???? i want to see turbo boost use it and maybe highest OC possible

6:55 Wow I can finally play X-Plane with realistic sound!

Just imagine the overclocking possibilities to this monstruos mod.

"In a quiet environment" Im sorry, my gpu fan is too loud..

One slight note with this Gpu heatsinks aren’t only cooling the processor die They also cool the memory, power delivery, etc especially with modern, and hotter and more performance based cards Otherwise this is pretty great

"This is a super power-hungry card that has a tdp of 250W" Me sitting here thinking about the 3090's tdp of 400W

Surprised LTT hasn't done this already

His accent and voice somehow makes the video even better

First time watching a video on your channel and I loved it and this was 2 years ago! subscribed! :D

I love the videos. ... not a stupid face made, not one thing done in the name of grandstanding for subs.... just informative well thought, well spoken ideas. Bravo

Now mount a GPU fan on the CPU!

Would be nice if you could arrange all components (PSU, GPU, RAM, CPU, etc) in a line. A solid row of heat sinks and fans, so that the computer case is effectively a tube. It would be interesting to see

One of the best tech channels. Every part of your videos are always so skillfully produced and presented. I especially like the audio. It almost feels like an asmr video :D Anyway, this crazy cooling experiment is something i've always wondered myself

That is very efficient man. Respect for the mod :)

I loove how thorough and scientific you are. You even included the room tone. Amazing. Thanks for the videos!

2018 edition Released in 2017 Using hardware from 2015

Inductor/choke/coil related noise is an artifact of air surrounding the coil being excited with a beat frequency of the DC to DC POL supplies. I've seen sealed coils which have epoxy/silicon applied to the coil which isolates the air from excitation. Another "trick" is to be sure your fans are mechanically isolated from the mounting points. Putting a shim of foam rubber between the two surfaces is a nice solution. I've even seen mounting screws replaced with rubber pegs such that the rigid attachment, too, can float a bit. If you listen to a fan suspended on rubber bands in open air they are surprisingly quiet. It is often the transfer of mechanical vibration onto a large radiation surfce (think Klipsch speakers) that is the source of the annoyance. --- Alternatively to this hood ornament approach is to construct your own liquid cooling loops. These need not be rigid bent copper tubing. The only thing that needs to be metal is the heat pad affixed to the GPU chip and of course the radiators. If you look at Chinese sources like banggood.com you will find all the bits sold separately to do this. Collecting all the heat and transferring out to a very large radiator with a very large push / pull serrated edge fan (which is very quiet and can move at slower RPM's) is a simple and elegant solution. As it is connected by hoses it really need not be co-resident in the enclosure. Of course this is for a permanent installation and not for your rig where you expect to change configuration a dozen times a year. Cheers!

Hahah the end, I ramble on just like that when I'm stoned and talking about tech. I was hoping to see some OC numbers. Loved the Vid. Stay safe

I love that you are getting sponsored equipment.

Can't hear the silence through my tinnitus. :(

U have kept improving drastically!!? Awesome work Matt

You seemed very optimistic about this and this is a great video. It's really cool, I wish I had some knowledge so I could try something similar.

I saw Noctua fans and I clicked.

My god that coil whine is BAD.

Awesome video, thank you for taking the time to share with us.

I salute to such pioneers of experimenting! Endorsed and subscribed!

Manufacturers please send your stuff to DIY perks as he does much more interesting things with them than most tech bloggers.....

PLEASE NOCTUA make for us GPU's

Im tempting to do this, since temperature really bugging me off. And the aesthetics look isnt my priority. Great idea sir 👍

bruh that's a wild experiment keep up the good work

I like the experiment, the CNC milled heatsink bracket looks like a really elegant solution. The water cooling market has grown so much in the last few years that it's relatively easy to build a custom loop. My first water cooled PC was a challenge because water blocks, fittings, radiators, and pumps were pretty basic and it was essentially up to you to make them fit. Nowadays, though, most modern cases have built-in support for water cooling, and there are so many fittings, extensions, brackets, and adapters that you can just buy a bunch of parts off the shelf and slap a loop together in an afternoon. Not unlike building the PC itself.

I love your vids, and wish you would upload more, but I understand you have other things going on.

Great! thanks, I know, I never will do such thing, but I love to see this kind of experiments!

Beautiful, I dreamt of making a machine like this without a cabinet. Big fan lovely build

Wow dude, your production quality is getting so good. Not that its ever been bad. Great video

To remove the coil whine you will have to fix the offending coils. First you locate them. It shouldn't be too hard by ear, but peessing down on the component hard with your finger should make it shut up. Next you have to minimize the vibrations. You can either pot the coil or replace it. To pot the coil you desolder it and put it in epoxy potting compound in a vacuum chamber. There's a quite ingenious $20 vacuum chamber video on youtube. This could be a great project on its own. The guy makes the vacuum chamber out of a glass jar he puts on a wooden cutting board. He drills the vacuum line in the wood! The gasket is made by pouring silicon under a ring of rubber he cut out around the circumference of the jar. Another option is to find a replacement coil. You send it to an electronics engineer with a good RLC bridge who gives you the specs and you find a similar coil with the largest possible physical dimensions. Or smallest. Try a few, they're not expensive. Maybe you can buy ones already potted. Note that this has a higher chance of burning down your card but also if you figure out what coil to buy then the viewers will find it easier to follow this (as they just need to buy the part at eg mouser). Finally the coil might be whining because it transfers transients that it doesn't have to. Try bypassing it with low esr capacitors. The circuit should be like this: coil - 0.01 ohm resistor - capacitor bank - electronic load (gpu chip etc). The capacitor bank should have an ESR of less than 0.001 ohms up to 40 kHz, which is not easily covered by one capacitor, so you will need to get multiple, and get them characterised with an ESR vs freq curve that does at least ~5 points per octave. A datasheet only does 1-2 points TOTAL over full freq range so you need to do this measurement yourself. You need a goodish bridge for that (it'll cost upwards of 1000€ so find someone who has one with that capability, or build one out of an audio interface and bridge circuit). I would advise you to try two coolers. One on the backside of the graphics card. You will not believe it but in my silent pc builds this made a noticeable difference on a cpu - using just a small cooler - so a gpu should be even better since there is no socket inbeteeen. Use one of those rubber ish thermal conductive mats to mount the backside cooler. I think you should see a drop of 5-10 degrees at least. And make sure the card is vertical, so no hot air is trapped underneath. That can make a huge difference. Use an equally large cooler for the backside to give it the same kind of chance of functioning as the front side cooler. Finally, i think the heatspreader you left on the card might be keeping it warm.

Nice mod! Congratulations for an excellent video and comparison. Loved it!

That naked ITX rig looks awesome. :-o Maybe you could create a case based on your test rig?

Great job !First time first. Amazing content.

About stopping the "Coil Whine", you can cover the effected component (s) with RTV Silicon, or look at the part# and purchase a new one. Proceed at your own risk, and don't try it, if you can't solder well.

Great video! interesting use of a giant CPU cooler on a tiny little GPU lol it looks awesome.

I did it. Thanks for great idea. I bought cheap cooler for one old graphics card. Now my temps are little above ambient with only case airflow. Great idea!

I also hope motherboard manufacturers experiment with the PCI-E socket orientations and angles for small form factors :) I would love to see the card and mainboard side by side and two stacks of heatsinks. That way you could possibly have two big heatsinks as your side panel off the shelf ;D

You should try Thermal Grizzly Conductornaut! And get a PWM mini adapter you can hook up to the GPU and can set a manual curve! Also mind sharing the bracket design for NH-D14 pls? Now this would be interesting to test on a Vega 64 card 🤔

I just LOVE your videos! Happy Valentine's day! :)

Wow, what a GREAT PRESENTATION and video creation!

Its been 5 years since u uploaded this video and m imagining how rtx 4090 can be cooled using this method 😂. 4090’s already have a big chunk of heatsink on it.

Was a beautiful mod. Thanks my friend, I will try this soon. Take care.

I know the video is like 2 years old... but putting an awesome cooler on a graphics card... I love you

Thanks this is a serious channel and nobody would scream at the background room-tone part.😆

@DIYPerks The Coil Whine can me mitigated by using thermal pads on the inductors and power delivery. The pads work as sound and vibration absorbers from the components. That is one of the reasons why card manufacturers use them instead of thermal paste/glue. Now I will warn you this method will not get rid of "all" of the coil whine but it should reduce it enough to where it will be "mostly" inaudible.

When I first build my PC recently I was surprised how loud coil whine is on cards. I don't have a screechy loud whine, but it is definitely audible, more so than the fans themselves. It's in particular noisey on full load (high clock speed) and full power draw. EVGA RTX 2070 Super. Runs at 1930-1880Mhz. At the spec sheet base clock of 1605 it would be completely inaudible.

Just discovered your channel and I have to say, I would love to see the follow up to this! The mini-ITX build with the chamber on top for air cooling sounds really creative. I just watched a video on JayzTwoCents that uses a modular mini-ITX case that might just be perfect for something like this. The Louqe Ghost S1 MkII was the case he used, but you can put multiple modular sections on top to make a section large enough for the CPU cooler graphics card chamber, which just seems like it would be awesome!

inspiring bro,i liked this work very much if i find cheap parts i want to try it ! silence is impoertant thing :D

1:01 Vega 64 is smiling. ;)

Enjoyed it, thanks

I think I can use my mini fridge as a case for my next build, lol "cat mic" aside, quite a nice test, very thorough. I get that most people won't do this, but the fact that this dude is thorough, made this a super enjoyable video

I was pleased buy your wonderful professionalism in testing, 100% clear 100% understood thanks

Great video! Could you show us VRM temps before and after changes?

What a great mod and video! You should design your own case. And try selling those CNC mounts on Etsy or something.

Thank you! I've also constructed one myself now. Additionally, it serves the purpose of warming my hands as I can direct the warm air wherever I need it.

I really like the setup and it works very well. As for the fan noise I think it might be the pwm drive frequency from the video card fan speed controller and its within audible range.

5:25 How about having the 3rd fan on the top blowing the warm air up and away?

The coil whine can be reduced or even eliminated with epoxy, just make sure it doesnt conduct electricity.

You are one of the best channels on YT.

Why i like your videos? = Clean voice = Good explanation = Great Quality of videos Very informative and good channel

Even overclocking can reduce coil whine. Typically simply changing power usage can improve things

i want to see the same configuration in SLI

This channel reminds me of a clear spring day

very detailed explanation. very informative.

4:33 we finally discovered cold fusion is possible xDDDD

1:41 The perfect form-factor. Please make a video for building a case in that size :)

Great video, I was looking a doing something just like this.

Experimento fantástico! fiquei impressionado. Obrigado pelo vídeo.

I broke my cheapo GT640 fan a while back, fingers and blades don't go well together, anyway I thought that gpu was destined for the bin, wasn't going to buy another fan for it, but decided to keep it just in case. So anyway fast forward and I needed a graphics card to power a basic screen for a server box, didn't need anything special, dug out the gt640, and guess what a standard clip on Intel CPU fan fitted perfectly on the MSI GT640 heatsink. Perfect!

Make a video about how you have that motherboard mounted to the power supply for that test bench. I think more people would be interested then you think.

You got an instant like after I saw your testbench. #BRILLIANT

I watched it some time ago, just rewatched it, and would like to like it again.

Great stuff! Perhaps try the PCI-E extender cable and mount the GPU in a baffled case to cut out the coil whine frequencies?

I can imagine the sag when installed horizontally into a case

New sub from South Africa :)

You are a hardware artist, awesome skills.

Not even 3 minutes in and I love this video already. How have I not come across this channel?? Edit: Holy shit this video is already 2 years old :O +1!

So it's settled then, put a nh-d14/15 on everything to make it cooler. Well done.

i wanna see you put this in a diy case! bling it out to look like a beautiful beast!

10 stars - best video I have seen in a long time

Using an AIO cooler will keep your temps in the low-mid 40's, and still be pretty quiet.. also much easier to mount in a case. I get though that this is pretty much a proof of concept kind of video, and I certainly dig it.

very professional thanks o7 incidentally my 980Ti runs @1400 mhz all day under 40'c custom water loop ; )

I knew it could be done but thanks to you, now I know how!

incredible video!!

Fake video, there's no sun ☀ in England ;D

Did you try taking the fans off entirely for a passive solution? I'd love to know if such a thing would even be possible on a 980ti using this method specifically.

Wow I’ve heard people talk about coil whine before I’ve never actually heard what it sounds like. I thought maybe that was the fans at first. Cool video.

summer time mining here I come, thanks for this ;)
