Nvidia minimum fan speed - why does this keep happening?

I don't have this problem with my 4070 Ti because it doesn't draw enough power for the size of the heatsink. Browsing the web it uses 21-23w with some very infrequent spikes up to 50w, the temperature is 41c in a 21c room. When watching a 4K 60fps Youtube video it uses a steady 29w-30w and the temperature stays at 47c.

The worst case (non gaming) scenario for me is using RTX video super resolution at quality level 1 to upscale a 1080p 50fps video to 4K, this uses 43w and the temperature reaches 53c. Even in the summer the highest I've seen it get to is 57c which isn't enough for the fans to kick in. I don't have good airflow in my case either as I'm using a Define R6 with 120mm fans running at 600 RPM.

That's all the 5090FE draws as well, but the fans kick in at 50c not 60c so you get it sometimes when browsing the web or watching youtube
 
That's shocking, very poor from Zotac. I'll update this thread when I get the Vanguard.

Ok, I've been playing with the Vanguard 5090 all evening, so have tested the minimum fan speed. With the silent BIOS, the minimum ('30%') is 1,000rpm.

That's not silent, but it's still reasonably quiet. The great thing is, the temperature threshold is quite high, the fans are still off at 55 degrees. So it's unlikely they'll come on at 'no load' and it's pretty quiet at 'low load'.

I'm not sure if the Suprim has a lower minimum, but this is good enough for me for now.

Some other points:

  • Max fan speed is 3000rpm
  • At 600W, in a 20 min stress test, and in my setup, the fans peak at 1530-ish rpm. Surprisingly this isn't that loud, although I'm still adjusting case fans, so I could get it down further.
  • With the Gaming BIOS, the minimum fan speed is 1300rpm. The performance of each BIOS is the same, so there's no need to use the Gaming BIOS.
 
I was curious to see how easy this issue would be to fix if I upgraded to a 5080 as the fans randomly spinning up at a high RPM would really annoy me. I bought a cheap Thermalright 92mm TL-P9 fan for £5 and attached it to my GPU above the flow through area with a couple of cable ties. I set the fan speed at 35% (790 RPM) which is inaudible, it starts to become barely audible at around 40%.

The idle temperature while using around 20w went from 41c to 32c. Watching a 4K 60 fps Youtube video (29w) went from 47c to 35c. RTX video upscaling on a 1080p 50 fps video to 4K (43w) went from 53c to 38c. For non gaming tasks this would be comfortably below the 50c or 60c limits that the fans kick in.
 
I did some more testing on this MSI Inspire 5080. It's not really possible to even get the fans to kick in with non-gaming workloads. When it does kick in, it's at 60c/30%/1000rpm, which isn't really discernible over my case fans at ~700rpm. Even 30% drops the core temp considerably, so weirdly, lighter games result in a cooler GPU than desktop use. Fans reach about 45% with heavy gaming. The whole PC is incredibly quiet with this GPU.
 
hello, first post here.
recently i have an inno3d 5070ti with 3 fan cooler.

is there any way to replace the stock fans with others lower starting speed?

it seems that the cooler has a piede where the fans are attached (on the cover i think) but at this point i didnt found any mod.
 
i found this 3d print model

and i think the lateral screws could work with the original frame. i need to measure the distance between holes
 
My one pet peeve is my fans running at 1200rpm, if anyone has a solution let me know.

which is super annoying when the other fans in my case are sub 500RPM :D so literally silent for the most part.

Besides that really happy with the 5080FE minimal coil whine and fans don't ramp up too much either in use.

See how I feel about it, but it is annoying me when I'm not gaming, even though the fans aren't even that loud I've gone from a silent desktop PC when not gaming to one with slight noise :(

The fans run at 1200rpm all the time when not gaming?
 
I've not found a solution yet for my zotac 5090. Kinda just had to get used to the fans randomly turning on when watching youtube videos/browsing. I'm generally always wearing headphones which helps.

It's really dumb that the card has a "quiet" bios, but the lowest fan speed at 30% is still 1300-1350ish lol. It's not quiet!

Yeah, they're on for me regardless, probably something I need to turn off in bios? or afterburner perhaps?

Have you made sure you've got the "auto" button ticked on afterburner?

I dunno if it got changed but using manual controls used to stop you from being able to use the fan-stop. It's been a while since I used a manual curve in afterburner though as I've not found it necessary
 
They're off below 50c, 1200rpm is the minimum speed when they come on
The solution is what I posted before, zip tie a 92mm fan above the flow through area pulling air up and set it at a low speed.

Here's what it looks like on my 4070 Ti, it would be tidier if I had the zip ties and cable facing the other side but I have a solid side panel so it didn't matter. I'm not sure if there's anywhere to attach zip ties on a 5080 FE other than going all the way around, but you could use it without as long as you're careful when moving the case.
