I upgraded both CPU and GPU to i9-10920x and Asus 2080 TI.
the CPU is running at 96degrees C and GPU at 85C using ultra setting with slight jerking, a lot of money. They are running at 25% and 91% capacity respectively. With no overclocking.
In comparison, x-plane 11.50 pre-release #1, at max setting is running at about the same capacity,- but temp is 55C for the CPU and 72C on GPU.
Efficiency and fine tuning is still required. I hope, I hope.
Better cooling required I guess, I run and 3800x 32ddr4 3800mhz 2080ti all over clocked, sim on ultra at 5120 x 1440, gpu never gets above 70c and cpu 68c all on air cooling
Agreed, I would revisit the cooling parameters you’ve set for the CPU/GPU
I have a 2080 and have MSI Afterburner to tweak the fan curve as MSFS is the first piece of software I own that actually utilizes the GPU to 99-100%. Temps never go over 70c in my case.
I would suggest going into system BIOS on startup and seeing if the CPU cooling is set to “Perfomance Mode” or equivalent for your CPU temps. Current temps won’t hurt your hardware but might hinder performance.
Also the i9-10920x has a high TDP (165w) so a beefy cooling solution and good quality thermal interface material is a must.
EDIT The Thermal Junction of the i9-10920 is 94c so probably best to look at cooling sooner rather than later as it’s probably throttling clocks at those temps.
Perhaps you know about this stuff already. My GPU in particular is also running a bit hot. Haven’t tried dropping its voltage yet or creating a more aggressive fan profile but I noticed that in the Control Panel, Power Options, Change Advanced Settings that came with my computer, the Dell Balanced Power Plan has the fan cooling options set to “Passive.” Going to the High Performance power management plan changes the System Cooling Policy to “Active.” And the fans now crank up higher earlier on my computer and it’s now a couple of degrees C cooler when running the sim. Perhaps this setting is the first thing any true gamer changes but as 74-yearold newbie, it took me a while to figure it out.
my toaster: Controlling GPU Temperature - Checklist of Things To Do on GPU Settings, PC Case Modification?
Especially high GPU temps are often caused by insufficient airflow in the case. Are temps decreasing when you take off the side panel of your case?
Not sure if you’re asking me or the OP about taking sides off case. I read somewhere that taking sides off case can hurt more than it can help if there is an intended airflow inside that’s supposed to be channeled over various components by the case design and case sides - some components previously in a bottom to top air flow impelled by convection and interior fans (mine has a big one right near the top vents) may no longer have the benefit of air being drawn over them as much. I guess the Dell XPS 8930 SE case is so tool-free, it’s easy to take off at least one side and see if it helps. And just put it back on if it doesn’t.
Yes, of course when you have a system that is already well adjusted in terms of airflow, removing parts of the case may reduce its efficiency. However, for troubleshooting it’s always worth a shot. As you said “see if it helps. And just put it back on if it doesn’t.”
If it does help (and in my case it helped a lot), it may be time to think about getting a new case with better airflow.
If you’re overclocking it’s also always a good idea to tune fan curves.
(Btw. I was actually not adressing anyone in particular as I think these hints could help everyone who’s having problems with temperatures.)
Thank you very much for the many suggestions.
Indeed I went back as many of you suggested, to look at the cooling fans inside the case. Found one fan not turning at all and the second was factory installed in reverse, blowing in instead of out.
Now cpu and gpu are running in idle at 35C and 45C. Which is very nice. While running MSFS in Ultra at 81C and 82C respectively.
Still hotter then I wish but more reasonable. I think my i9-10920x is just a hot unit.
Thanks again
Not related to FS2020 only. My story:
I built an i5 9400F PC with Gigabyte 1660Ti OC something last November (this GPU has three fan units on it). My CPU came with the stock intel fan.
It was always very loud, revving up/down the fans. I always blamed the GPU (3 fans must make more noise than one, right).
Then I installed MSI afterburner last Wednesday and found my CPU was running 95-98 Celsius, there were one or two occasions where it reached 100 Celsius.
After quickly switching off the PC and changing pants I rushed to the nearest small PC store, got a Coolermaster Hyper 103 (a budget cooler, they only had this at the time).
I swapped the stock Intel fan with the Coolermaster and now my temps are in 50-60C, sometimes going up to 68C. The revving noise also disappeared.
I was naiive to believe that the stock Intel fan is effective, but it’s complete garbage.
Due to the accumulated heat in the PC case my GPU was also running hotter than now.
So in case someone has a stock cooler, time to throw it away.
I am running a GTX1080 and when I’m running MSFS, the GPU is at 100% and about 82 C.
But, I don’t think that is outrageous because here is how it was set from the factory.
Don’t like it… but this sim will push your GPU for sure.
Totally agree. I am always throwing away the CPU stock fan.
I have this kind of fan since years now, moving it from one CPU to the next one.
Indeed a very good cooler. I had a stock cooler on my old i5 2500K processor and it used to run at about 75-80C. Changed the thermal paste and it dropped a bit to 70-75C.
Stuck a coolermaster one on, similar to your picture, and it dropped down to about 40-45C. I was then able to overclock it quite a bit and still keep it under 60C.
My CPU is water cooled… it’s the GPU I worry about.
For the CPU, check if your chip is running at max default boost clock and if so try to put in a negative AVX offset of about 200MHz in the BIOS. MSFS makes heavy use of AVX which is pretty demanding for the CPU.
Try limiting your FPS. I get better results using the ingame limiter but others seems to prefer the nvidia limiter…
Improves more than just your gpu temp, it’s much smoother and less stutter and may also enable you to turn some settings up for better visuals.
It is a demanding game without a doubt, but I have not noticed an increase in temperature (i4790K with GF1070ti titanium).
However, I must clarify that I am dedicated to computer repair and if I can tell you something it is that many times when a certain value is exceeded, temperatures skyrocket and it is difficult to control them.
The best way is to keep the equipment clean of dust and lint internally, to have all the cables organized so that they do not interrupt the air flow and of course to use a first quality silicone grease. In my case I use the Gelid Extreme (the same for the CPU and GPU but I also change the silicone thermal pads of the video card every year.
Beyond that, it would be necessary to think that the power source does not deliver the correct values ​​under strict loads and obviously I rule out that you have overclocked your equipment.
My PC is a I7-9xxx with Nvidia 2060. My GPU is very hot, while installing Updates. Ist there any Grafic activity in backround? i wonder while the GPU runs a lot while staying in Menu!
99% of the time overheating CPU/GPU is because of bad air flow. The inside of the case shouldn’t feel hot, that’s the air used to cool your components. If your case is 10 degrees hotter than ambient and your case fans already run at 100% your components will get 10 degrees hotter too.
96°C? You need more and faster spinning fans.
And a bigger CPU cooler 
I recommend the magnetic levitating Corsair M120 and M140 fans, they can be turned on to extreme powerful settings (the big 140mm are rotating with 1850rpm, and the small 120mm ones with 2450rpm).
