You could put the fan on the CPU cooler the other side in a pull configuration. A Zotac 5090 will probably be long enough that you don't need to though.

Nvidia minimum fan speed - why does this keep happening?

Tried auto and manual on afterburner and nvidia app, no success.
Honestly it's not that loud, just a waste of my fans in my build if the GPU is louder than anything else in the system with perceivable fan noise vs near silent.
Was told to try and boot into safe mode, but unfortunately because I use a pin I end up in a loop with it where I can get back to normal windows due to it being fully offline.
Not sure what my next step will be now, as otherwise it's the least coil whine I've had on a GPU.
I've thought about it before admittedly due to ram clearance, but I decided against it due to people mentioning it has worse accoustics.
I'd probably have to try test it for space I think it'd be tight either way, I don't think the zotac is as long as some 5090s.
Have you tried just totally uninstalling afterburner? I wonder if there's just something that's stuck in the profile. I don't see why you shouldn't be getting the fan stop under 50c.
I have a pin on my PC but I don't have troubles going into safe mode, so I find that part a bit odd though?

May have found a solution for others - Uninstalled afterburner as recommended
set your monitor to 60hz and performance mode to normal in windows and nvidia control panel
then change it to your desired monitor refresh rate once booted up.

Is that because the minimum fan RPM is... 0rpm because it's idle?
Nope. I have dual monitors so its rarely in fan stop to be honest.
I just tested this with Afterburner and a Asus TUF 3060ti if I set the fan speed % to 30% it turns the fans off its only till I set it to 40% it'll bounce from 200-800 fast and occasionally drop to zero though when looking at the fans they slow down and speed up. Proberly not the best setting for long term use but mine is always left on auto.
100% fan speed is 3k rpm and 50% is around 850.

So a 92mm fan does just fit. I put it on a pretty low RPM, think it's only 500rpm at the moment, and it's dropped the temps quite a bit at idle. Will see how it goes. I've not tied it down or anything yet, it's just sat ontop of the GPU, so I can decide whether to keep it. It sure is ugly as sin having an extra fan like that, hahaha.

Why? PWM % doesn't directly nap to speed %, it's an odd interpretation I nearly commented on earlier in this thread.
It's like saying that 50% down on the throttle of a car should be 50% of its maximum speed. It's not quite that simple.
500 RPM seems unnecessarily slow, which 92mm fan are you using? I have the Thermalright TL-P9, the ARGB version is more or less the same price which should make it look a bit nicer.

Its the thermalright yea. I haven't messed with speeds if I'm honest. I just set it low because I've not really used the fan before(I don't think I've ever used 92mm fans before this, always been 120 or higher) so I don't know its noise vs speed sweet spots. I probably can set it higher without troubles. It's hard to hear the speed of it when I'm in the bios because the GPU fan seems to stay on regardless with no fan stop.
At 35% (750 RPM) it's pretty much silent, while gaming I set it at 50% as it's not loud enough to be heard over my GPU fans. While gaming my GPU fans were running about 100 RPM lower with the Thermalright fan running at 50%.
Like you, I am very sensitive to noise. I optimized my desktop (AMD 9950X, MSI 870 Pro, Asus Nvidia 3060 GPU with 2 fans) to be completely silent using FanControl and having all my fans run at very low RPM - about 350 RPM for the CPU/case fans and 660 RPM (the lowest possible value) for one of the two GPU fans which keeps the card cool enough to ensure the second one never forcibly comes on.
I was about to order a 5060Ti card just now which were announced today when I learned about the appalling high minimum RPM of ca. 1200RPM for all cards whose review I was able to find, except for the Asus 5060Ti - which however consumes 2.5 slots instead of 2 slots. I'd prefer to keep all my PCIe ports usable, so that one's out.
However, I wanted to reach out since I find your idea of strapping a Noctua fan to the backplate of the GPU truly innovative. I have never heard about anyone doing this and certainly had not considered it myself since it seems very difficult to attach. How exactly did you manage to attach the fan - and can it be removed again from the GPU without leaving a trace, or did you somehow have to glue it there?
Thanks for the great idea. Maybe I get a 5060Ti after all and use your "Noctua backplate fan mount" idea.
Sounds like a great idea. Thanks for reporting the impact it had on your temperatures which is quite considerable. How exactly did you place these cable ties, i.e. did you thread them through the exposed fins of the heat sink, or did you wrap them around the entire GPU? Also, I assume you are blowing air into the GPU (from above downwards), i.e. in the opposite direction of a normal case's air flow which typically pulls in air at the lower front and exhausts them at the top and top rear - is that right? I wonder if it would be better to change the fan's air direction so it pulls air through the GPU (i.e. aligned with the direction of the rest of the case's air flow, moving from bottom towards the top of the case, thus reducing turbulence) - though I doubt it would be easy, as this would require a very tight fit on the GPU.

I already posted a picture with the zip ties, it's pulling air up which strangely had slightly better temperatures than pushing down.

Thank you so much. Since last week my clocks were stuck at around 2500mhz 75w and 500rpm (30%) on idle.
Didn't need to uninstall afterburner and power management was already on normal in control panel, so I just set refresh to 60hz, rebooted, then reset refresh back to 120hz, and now my GPU is back to normal - 230Mhz, 28w, 0rpm on idle.
What a wierd bug, what could cause this? Only thing I can think of it installing the new 576.15 driver but not sure

Chiming in since I just switched from 4090 to 5090 and found out in Fan Control docs that NVIDIA made the horrendous decision to lock Zero Fan Mode in firmware to a certain temperature range.
In my 4090 setup I configured my fan curve in such a way that the fan stayed at 0 RPM until the GPU reached 70°C. This completely eliminated the 30% min fan speed problem, since the GPU never reached 70° while browsing or watching YouTube and stuff. But this isn't possible anymore with the firmware lock.
So I am also looking for a solution to the problem. So far placing the 92 mm fan on the backplate venting area sounds promising (fortunately the card is long enough so that the D15 doesn't interfere), but I am also afraid of negative impact to noise during higher load since the Asus Astral has a fourth fan which makes it louder instead of more silent (reviews have tested this by stopping it forcefully).
Which other solution might help here?
Could custom firmwares be expected? Or is it maybe officially planned to roll back this rubbish firmware lock?
Do people use heavily undervolted configurations for desktop use to keep the GPU cool?
Is there a list available that shows the 0 RPM threshold temperature for each AIB?

I'm in the process of returning my 5090 Solid OC for pretty much this reason. The sound of it 30% and upward kind of sucks, but it is the start/stop that drove me spare. I was able to stop it happening as much but tweaking the slope with Fan Control, but it can't be avoided 100%. Even just the start sound when beginning and ending a game sounds dreadful imo.
The worst part though is that the fans drift in and out of sync constantly doing that "whoom-whoom" effect. (the thing that the Noctua/GN video explains)
Spent days trying to offset them, but they will not hold a set speed well enough to make it matter anyway.
I have a family member who has just strapped 3x 92mm Noctua fans to their 4090 and it is in a different league. Any % you want, any curve you fancy, and so much quieter than any stock card I've heard. I'm a bit jealous, but I can't be bothered with the whole thing, especially after spending a couple of grand.
I've necro'd this post I know, but it came up while searching to see if any 5090s have fan speeds that go below 30% lol. Seems the answer is no, so hopefully whatever one I do get at least doesn't make the cat jump when it kicks in.
