Great video, I have to say it feels quite good to know it's not just me experiencing the low rpm fan noise from these 4090 cards. I feel as though both fan quality/quality control has gone down the drain. I owned a Zotac 4090 Trinity OC and the first thing I noticed was the fan noise as they kicked to their minimum. After sending the card back and receiving an ASUS TUF OC, I felt the noise was much better, however at 30% there was still a noise. I finally ended settling for the MSI 4090 Suprim X. Yes, even this card has a weird noise at 30% but it is much quieter than the Zotac one. I think in my case, the one thing that doesn't help is that the rest of my PC is so quiet that any noise from the GPU's can be heard very well. I don't mind a bit of fan noise, but at 30% I feel they should be at least inaudible. I have ordered a replacement fan which should be coming next week and I will see if the set of new fans help. If not, I also ordered the Noctua shroud mod, which will allow me to replace the stock fans with Noctua fans. That will be my last resort. Whatever the case is, it seems most 4090s are using crappy fans this generation.
it would be more interesting with real vendors like asus strix, msi or evga cuz those would have better fans on paper, but at least you shown what getting cheapest 4090 is like
6:00 If the original fans spin at up to 3200 RPM, then the Bequiet fans will reach 100% fanspeed at around 50%? PMW is just telling the fans to go and spin at 1600 RPM at 50% fanspeed.
BeQuiet fans are limited to 1600 RPM with the physical switch at the fan. Had the switch been set to 3000 RPM PWM would drive them at 3000 RPM on 100% speed.
Hello! Unfortunately I don't have free time to re-adjust the 3D files. Please consider TinkerCAD and try to modify my files. It took me a while to learn the tool, but it shouldn't be too hard however. If you can't please contact me sometimes after the holidays and I will see what I can do. :)
Yeah, I have the same card and the fans while noisy, are nowhere near as bothersome to me as coil whine would be. I'm just glad it has zero coil whine.
Very nice video, Im playing with idea of doing this too but I dont own 3D printer :/ I made my research however and most GPUs have 100mm fans. Unfortunately no reputable brand like Noctua, Be Quiet or Arctic are making such sizes. They only make 92mm and then 120...
Is it possible to run fans below 1100rpm at 30%? I.e using some noctua ones? Could you connect fans to the motherboard instead? I want fans to run at something like 600RPM when not gaming
ALMOST NOT POSSIBLE , got the same card and the vga bios is set to only allow 30%. if you still need to you will need a resistor in between , noctua has them sometimes idk if you can buy them seperate
@@DexyII I managed to get the Noctua nfa12x25, running at around 1100RPM and they are silent enough for me. Running noctuas through motherboard at 30% runs them at around 600RPM, but when it's connected to the GPU it spins them up to 1100RPM. I think the GPU makes sure it's at least 1100RPM no matter what PWM signals the fans get.
I have similar fan regulation issue on Palit RTX 2080. I think card's bios regulates fans based on RPM number, not duty cycle %. So it thinks 100% must be 3500 RPM or whatever number shitty stock fans have. So at 50% it sets them to 1500+ RPM which maxes out Noctua or other quiet fans.
I also think that that is the case. Sadly BIOS development is dead so we cannot expect any improvements regardless of it still being the best gaming GPU available at this moment.
Sorry, I havent tested any other 120mm fans on this card. I guessing that Silent Wings 4 would work as PRO models ie. 50% RPM signal would run them at 1600 RPM.
Your shroud mask is nice, but it is tracking to much of hot air. You should try with open design of the shroud, or simply don't place any mask around fans!
The shroud is blocking air only between the fans. It does not cover the heat sink so the air can move freely as before. I don't think that it would make much of a difference regarding the space between the fans. In fact many stock designs are also having solid shrouds around the fans.
there could be a problem with RMAing it, some manafacturers dont accept returns if the card isnt damaged. At least in Europe (Slovakia) the stores don't do this, they give you like 2 weeks to return it.
Great work, but I think you got one of the bad ones. When the 4090s launched, I tried this card but I noticed that as soon as it came on it made more noise than my 10 case fans. After messing around and testing it it seems as though the motor is bad. There was a noise as soon as the fan got power. It did not get worse when the fans moved faster, it just did it as soon as it got power. I made a video about it th-cam.com/video/PZ9v3rgE9r0/w-d-xo.htmlsi=7eQU1LH6N0bx1wTt&t=103 I sent it to Zotac with forums full of people unhappy with this noise and Zotac said "Its fine, they all do that" So I returned mine and so did 100s of other people. TBH I would have thought they would have swapped the fan type/make, out by now.
ZOTAC's fans are just bad. My card suffers from poor bearing sound even the fans are OK in terms of generating big air pressure on high RPM. ZOTAC should use better fans or collaborate with partners (Be Quiet, Noctua, Arctic etc...) which make quality fans. Most likely the RMA numbers are low enough that nothing will happen.
@@RandomTechChannel The bearing was another issue. They used so-called "long life bearings" which they must have either not test run or gone with cheap and nasty...but they last. It's a huge shame because I thought the card was one of the better 4090s at launch.
never hear bigger bull*hit... watercooling its not cooling by standalone water... you stil need use also fans for cooling water insdie.... and all silence its based on quality and quanty of this Fans. Because quanty can improve airflow whole case and you can reduce spin of fans which reduse also noice due of speed. And also risk of failure on watercooling its also problme bc if system start leaking you can break pc... with standalone fans you just replace one of them. Water cooling have one plus its just better temps and you can put fans in other place if you dont have enought space for cooling CPU / GPU depend on size model.
@quassar89 Well... you have some valid points, but what you are failing to understand is that with custom watercooling, you can increase the eat dissipation surface as much as your case allows (with radiators), and with that, you can run the fans at their lowest settings full time, resulting in a whisper quiet PC.
This design honestly looks so clean, nicer than some actual AIB models
Thank you!

Thank you, i was planning to get this zotac card because it's cheapest rtx 4090 but lucky i saw your video
Thanks! Glad to help!
The fan rpm is based on a percentage of the original fan rpm, if the original fans would do 4000 rpm and the new ones are 2000, 50% rpm is 2000 rpm.
it would be more interesting with real vendors like asus strix, msi or evga cuz those would have better fans on paper, but at least you shown what getting cheapest 4090 is like
Temps won't be much different unless you change the pads and paste. So no surprise there.
6:00 If the original fans spin at up to 3200 RPM, then the Bequiet fans will reach 100% fanspeed at around 50%? PMW is just telling the fans to go and spin at 1600 RPM at 50% fanspeed.

Hi! I don't have enough clearance in my SFF case, Can you provide a 3D print for fan and shroud with 2 x 120mm and 1 92mm fan?

You should be gratefull your GPU does not have annoying COIL WHINE...
Coil whine can indeed be annoying if you happen to hear it.
Yeah, I have the same card and the fans while noisy, are nowhere near as bothersome to me as coil whine would be. I'm just glad it has zero coil whine.
very cool video i will do this to my next card for sure
Thanks!
Bro the stock doesnt even sound like a vacuum cleaner, more like a freaking PLANE. Hell no to Zotac.
Very nice video, Im playing with idea of doing this too but I dont own 3D printer :/
I made my research however and most GPUs have 100mm fans. Unfortunately no reputable brand like Noctua, Be Quiet or Arctic are making such sizes. They only make 92mm and then 120...
Thank you! The card on my video also uses 100mm fans. The size is great in terms of heatsink’s size.

Is this doable without outer shroud? Can we screw the fans on the smaller bottom plate?
It is doable. Please re-watch the installation process.
Can the regular Silent Wings 4 be used up to 1600rpm. 50% would be 800rpm and 30% even lower?
Sorry, I havent tested any other 120mm fans on this card. I guessing that Silent Wings 4 would work as PRO models ie. 50% RPM signal would run them at 1600 RPM.
Can you share the length of the GPU without any shroud on it please?
Unfortunately, I don't have the PCB measurements. Sorry!
could it also work on the Trinity version? Thank you
If it has the same heatsink, then yes.
Why you didn't use msi afterburner for fan curve settings ?
Unfortunately adjusting the fan curve won't solve poor fan bearing noise at fans' kick in speed.
@@RandomTechChannel okay

RMA, my zotac is silent and beating records in 3dmark
i hate zotac.
why?
u should have buyed the srix or the master card lol
that's why all my builds are watercooled.

Great Video. Zotac is garbage
Thank you!
max 1680 rpm vs max 3200 rpm lol
