So I dont understand how MSFS2020 causes my fan on GPU to go Off and On every 10 secs and temp go up so quickly. I have a R11 desktop and in AWCC I watched my GPU when I start the game jump up in temp 82° and then when I shut the game down the temp jumps back down to 65° in temp any other game I don’t have any problems with just MSFS2020. Any help would appreciated TIA

Fan(s) will come when the GPU gets hot and will slow down when the GPU cools down/has less work to do. MSFS works the GPU hard, it is going to get hot.

You could look at your fans (number of and placement) and potentially improve your cooling flow.
I added a 3080ti a few months ago and had fan noise issues, I changed the in case fans to Nuctua NF-S12A ULN and reversed the standard direction of airflow (now in through the back, out through the front) and it has worked for me.
You really need to look at the fan placement and flow in your own case and may need to experiement.
I believe MSFS puts such a strain on your GPU that it artificially aged mine. My old 1080 Ti was doing the exact same thing you describe. It was like the GPU was breathing. I logged a ticket with the manufacturer, and even though it was several years out of support they understood it was a cooling issue, and sent me a free replacement pack of cooling pads to be fitted.
I never used them in the end, and bought a 3090 instead. My best guess is that the GPU being run hot for long periods of time perhaps overheated the cooling pads, and if they get damaged they leave an airgap between the chip surface, and the heatsink.
When the temperature goes above 82 degrees the fans go in protection mode and run at 100% which makes a lot of noise.
Your thermal paste has probably dried up. Get someone who knows how to do it to re-apply thermal paste.
Also make sure you have good airflow in your case and all case fans are working.
I have not even had this computer but a year and now replacing pads etc. I don’t understand how 1 game can do all this. And to jump up and back down from temps. If I go into the AWCC in the advanced tab for the GPU and adjust down the temp and thermal then it stops?
Yes, that would be a start, and it may be enough to prevent the fans from cycling.
If fans cycling with the 2080ti temperature, check with the PC or motherboard manufacturer for instructions or apps to control fans. My PC has an external switch to run all fans at max speed all the time or “quiet mode” increasing/decreasing fan speeds as needed.
Regarding the 2080ti temperatures, my 2080ti runs at 82°C when running MSFS. According to NVIDIA, this temperature is within specifications. If the temperature rises too much (like 100°C), the card is designed to throttle back significantly and quickly to prevent card failure (and probably cause a CTD for MSFS).
more than 65 I dont see 
… 85 is in spec, but a bit hot and in throttle range… the max (gpu) is so far I know 89 C.
My 2080ti runs at about 82C as well under load. Alienware has the max temp set at 84C in the ACC. When running the sim, I use the “performance” setting in the ACC thermals settings, this reduces the temp to 78-80C. I run it in “balanced” when not using the sim resulting in temps in the 60C range.
This is a known issue with some 2000 series gfx cards. The thermal paste on the GPU is ■■■■ and dries out after a couple of years. I had to remove the heatsink on my Aorus extreme 2080ti, clean up and apply new thermal paste. After that my GPU fans no longer ramp up to insane RPM’s every few seconds. Tons of tutorials on YT on how to reapply thermal paste to your GPU’s.

how old is your card that the thermal paste is out of livetime ? 
For me there is all about ensure a good case airflow and not overclock the cards , or set utopic power limits, and on… The result of these “optimizations” are often 2fps more and lots of strange issues.

My issue was nothing to do with my case or other cooling. My 3090 works perfectly fine in the same case. The 1080Ti is quite a few years old now, and I guess the thermal transfer material had failed, causing the overheating, and “breathing” of the fans. I have the thermal pad replacements from EVGA, I just never fitted them as the 3090 turned up.
you mean your nvidia 1080ti not survived 4 years ?
I have much older cards here with no issues and my 2080ti is now also three years old, still 60 C.
We know about these horror stories related to 3090, but the older cards ? If nvidia cards have such a wide range in production quality, I no longer wonder why we see so many issue reports in forum.

Additionally to the given suggestions, look out for a guide to undervolt your GPU.
That saves some energy and reduces heat dissipation without losing any performance.
Most cards can reduce the power consumption by 10-20% resulting in a lot less heat and prolonged life of the components.
I think my 1080 may be older than that, I’m not sure. But I’m reasonably certain that MSFS made it work hard!

I totally get about just working around windows etc compared to running and playing MSFS2020. But that much of a difference? My temps will go from in the 60° to 84° just loading the game and and I watched the temp when I shut down the game and the temp jumps back to in the 60° range? This computer is only a year old?

That’s normal behavior for this card in this computer. Mine has done exactly that since it was new 3 years ago and it does exactly that today. Normal behavior and well within max parameters. Time to move on and worry about how to do a smooth landing!

I have an Aurora R9.
Same type of case….those things are pretty hot due to the less than optimal case layout.
I had to put in better fans as well as remove the HDD from the front and put in another fan there.
(Replaced it with a SSD in the bottom bay)
In AWCC I set up custom curves for the fan speeds.
Also, I had to under-volt the GPU (RTX2070 super, blower style) using MSI Afterburner.
I set up a custom fan curve for that as well because those blower type cards tend to run quite hot and noisy.
It idles at around 35C and MSFS now runs my GPU at about 65-70C
