My MSFS2024 simrig is in a Corsair 7000D Airflow case with the side panel off, and a fan blowing onto the gpu.   Do I need to do that?  No.  Do I want to do that?  Yes, because it drops my gpu temps by about 5-10C in a typical sim session.  Could I find a more elegant solution?  Yes, if I really wanted to spend the time, I could install another fan inside the case, blowing across the gpu....but I don't really care, no one sees my case and it's under a table anyway.  I'd rather be flying.

I have another machine with a 3080ti in it and...as most 3080ti's do, it runs quite hot.  Your 3080, well, imagine if you had a ti version.  Heh.

I want my 4090 to last a while, because of the gpu prices.  Anything I can do to prolong its life, I'll do it.

The suggestion about limiting frame rate is a good one.  Limiting frame rate is the most direct correlation to heat production that I know of with a gpu.  Outside of ensuring it's getting good cooling.   Limiting framerate is even more effective than undervolting or underclocking a gpu, at least in my experience.

Me: rig on test bench, two 120mm fans mounted at each side, using fan control, good temps. FPS unlocked => GPU 99%, locked around 70%.

Any aussies?

 

Im.looking to buy a 4090 

For 2500$ AU

Is that worth it?

Its. A suprim x msi

Or do they overheat?

Not now, not 2 weeks before the release of the 5000 series!

1) ups and downs are symptoms of GPU throttling down to keep temps within specs.  sounds like overheating and inadequate cooling.

2) this "terrible" application has run for 4 years with not a single crash and restart of my pc (a lot more powerful than yours). but with good cooling.

the NVidia 3000 GPU series is known for overload power "spikes" which combined with underpowered power supply can easily crash the pc. a 1.000 watt psu and a RTX 4000 GPU can fix that.

 

Igor's lab has identified and described the problem and solutions already back in 2018:

You are seriously trying to claim MSFS2024 has "run for 4 years...".   I'm not sure you understand the OP is talking about MSFS2024 specifically.  He even stated MSFS2020 gives him no problems like this.

I am not sure you read/understand my detailed posts where I explained the difference MSFS 2024/2020 as far as increased GPU load and with it power supply crashes due to GPU load spikes are concerned.

I obviously included MSFS 2020 + MSFS 2024 period (2 +2 = 4) in which I never had a single pc crash with either simulator after I upgraded my power supply from 600 to 1.000 watt. 

if you are interested and read my posts carefully: I explained very detailed why MSFS 2024 is a whole different "game" as far as GPU loads and hence power requirements go.

I think he has understood the issue now, i.e. why the same power supply that works with MSFS 2020 now may shut off with MSFS 2024. what he calls "terrible" software is actually most advanced software in any flight simulator, called GPU programming.

Ya but in aus they are like 4200 for a 5090

‘Kin ‘ell!😔

at 14:35 time mark:

"certain games I play my system just shuts OFF. anytime a system just shuts OFF and you hear a click, ( that's a relais) that is overcurrent protection in your power supply. ... it could be transient spikes....."

Yep 

That's Australia for you.

We get shafted of everything 

Thanks Turbomax ! This is exactly what I am experiencing with my 7830X3D so tomorrow I'm off to get a hefty PSU. I couldn't figure it out. Thought it might be a thermal

protection.

 

thanks Leftseat, glad if I could help. if you are getting a new PSU I would make sure not only to get at least 1.000 Watt, but also the latest standard:

ATX 3.1 PSU  [PCIe 5.1 Compliant with 12V-2×6 Connector]

Another option to reduce fan noise is to use MSI Afterburner to limit either power or temperature to get a satisfactory outcome. You can also save it to a profile and set up a hot key to quickly switch between the two profiles as you please.

Ok, thanks again.
