Tried all sorts of experimenting to control the fans on my current 3090ti (MSI afterburner, Fan Speed Control etc) and no matter what I do I still end up with at least regular bursts (every second or so) of max fan activity that is driving me nuts. I'm running DX12, DLSS (auto), and have TLOD-300 and OLOD-200. I used to have the same settings with my Titan RTX (card before this) and the fans there were never as noisy.

So two questions - anybody else running a 3090ti happily but quietly?

And second, is the 4090 a noisy b*gger? I might replace the 3090 with a 4090 with an AIO cooler package, but I don't want to spend a whole bundle on that and end up even worse off.

GPU temp consistently no higher that about 75-80C, utilisation seems to top at about 90%.

Don't seem to have the same problems with the other sim, which is also running at maxed settings in sim and highish GPU utilisation.

Oh, and all at 4k, both sims.

Any advice/suggestions gratefully received. And I've posted this here rather than the hardware forum as it only happens with MSFS, even though the other sim is giving the GPU a workout as well.

Sounds like the GPU is working as it should. With the exception of the menu screens having your GPU utilized to its full potential or close to it especially in this sim suggests to me that everything is balanced nicely (Your also rendering MSFS in 4k so your GPU will have to push a lot more pixels is the other sim rendering in 4k?). You can upgrade your GPU to something faster if you want to lower utilization. Or if there is a cooling issue and you know what your doing you can do a clean up the fans and repaste the heatsink.

Also some GPU's have not so great cooling solutions. You didn't state the manufacturer and model of your GPU so i cant look it up for you to see if the respective cooling solution was overbuilt and should easily cool your gpu or just simply adequate and may run into issues when the dust starts to build up.

Do you limit frame rate in any way?

I find that if I run vsync off and no other frame limiter, then my gpu fans can spin up.  However, normally I limit frames and that tends to keep temps down (and fans quieter).

I forgot about that cooling option .. Thank You Mace. Yes in my personal situation my frame rate is limited to 50FPS. If the OP wants to go that route it is a viable option if the user has FPS headroom.

it has been very warm  in the UK last few days bare in mind , well in Yorkshire anyway 27c

Try 30 FPS and see if it becomes near silent. It should.

Even with GeForce RTX™ 4090 SUPRIM LIQUID 24G you will get some noise, meanwhile, you can try this for your card https://youtu.be/SIlXT32fOMk. If you go for 4090 this is also an excellent tutorial https://youtu.be/WjYH6oVb2Uw. As it was mentioned, unlimited FPS will kill all of them in MSFS2020. It's not correctly optimized.

4090 is way quieter than 3090.

Kill all of what? Graphics cards are designed to run at full welly for years. It wont do any harm at all, other than annoy you with fan noise. Search this forum. Countless threads on this. 

I had the EVGA 3090 then upgraded to the Founders Edition 4090.  I can tell you the 4090 has been significantly more quiet for me.

due to its massive nuclear cooling solution

I only run MSFS with HiFi, not communications, headphones on. I do not hear cpu nor gpu fans.

Kid's noise driving parents crazy.

 

You can setup your own fan curve in bios, bigger fans (140 mm) in your chassis will also help lower the noise, but the only way to to keep your GPU quiet is to reduce its workload, capping your frames is the best option.

High-speed running of computer fans is a clear indication of high temperatures. That will lead to premature failure of the components, shorten the life span, and eventually kill it. You are more than welcome to believe that high temperatures and high fan speeds are not an indication of a problem and are not harmful at all.

@Maxis, thanks for the reply. My card is ASUS 3090Ti TUF Gaming OC, and I don't know how that card is considered generally, but for me performance has been good, it's just the fan noise that I'm finding hard to livve with. I'm running 4k on all sims, and XP certainly seems to be getting high utilisations but a lot quieter. There is definitely some ham-fisted coding embedded in MSFS - things like the GPU racing away in the menu screen, at odd moments when sitting parked at an airport etc. It may just be "one of those things", but I'd like to resolve it if I can - I'm hardly using MSFS at the moment, the noise takes all the fun out of it for me.

Thanks guys. I was running with a 60 fps limit (although I rarely get near that with my settings), but dropping that to a 30 limit (which I can do comfortably) has no effect on the noise.

Cheers Sonny but it's done this all the time I've had it, over the last 15 months or so

Cheers LRBS, that looks interesting and I'll play with that tomorrow and see how I go

Thanks guys, that's good to know. I may yet go down that route - I would have bought one at launch time but I'd just got a new PC and the 3090 wasn't that old at the time so I demurred.  I'm not crazy about chasing FPS but I figure the 4090 has got to have a lot more headroom and ought to be pretty smooth on my system, but I was worried about the noise. The one I'm looking at uses a Corsair type AIO so that should be reasonably quiet but I did worry that a powerful card like this might be a screamer

I'm using a Corsair 7000 Airflow and the case environment itself is pretty well cooled, and frame capping doesn't seem to do it, so I'm leaning towards the 4090 at this point, I guess

Thanks everybody - appreciated.
