Hmm. I noticed mine went up to 86 degrees yesterday on auto fan though it was running nice and cool when I accidentally set the fanspeed to 60% 🙂

It probably has a default auto profile designed to keep it "quiet" .

It is my understanding that bad coding, like the spike in framerates (200+) noticed while the sim is in menu or is loading a flight, can indeed be the cause of overheating.

This can and should be corrected by turning v-sync on in the control panel. But your temps are still WAY too high, we have the same CPU, and I have much cooler temps and overclocked. I would reseat the CPU block with new TIM. Check voltages and temps with software real time to see what's going on. Verify you hear a hum coming from the cooler.

I do not understand this thread!

I've been engaged in "easy" overclocking on intel processors for a very long time.  My understanding of "safe" overclocking was to test your OC and temperatures with something like HyperPi or similar load generator and then adjust your frequencies and voltages to ensure that at 100% processor utilization on every processor the measured temps were within a range YOU find acceptable.  The "old" (15-years ago) rule was to run all processors at 100% for at least 30-minutes to verify cooling was adequate.

Each OCer has his own ideas about cooling and temp limits so it is up the operator to set the correct and "safe" parameters of overclocking.

I can see no possible way to blame ASOBO or Microsoft for high processor temperatures!

I do know from hard experience that I can overheat the processors with various combinations of freq and voltage despite what ever cooling I try.

Exactly! Responsibility for overheating always is at the person that built the pc or the user.

I did the ultimate MSFS stress test right now: I started with the A320NX at the infameous 3fps Bishop Airport in Texas. CPU temp peaked at 82 Centigrade for a second or so. I have my 10700K overclocked to 5200 MHz at all cores so this is the hottest I can get it with MSFS.

Temp thing has to be an issue with the users cooling.  I just checked while loading in and capped at 61.5 on a 3700X, though it's on water, but water temp was at 33-34C.  There's definitely some weird CPU issues though.  I can load into a "smaller" airport without a lot of dense stuff going on like KSMF or KLHM and get 50-55% CPU usage when I used to get around 30.  However I can then go load into KSFO (premium deluxe version if it matters) and CPU usage is only around 35% and better FPS by up to 4 in the CRJ.  The CRJ gets 29-30 at KSMF, will get like 33 at KSFO when the systems are powered up.  So weird.

True, there is clearly something else running causing the issues or he has a hardware problem. MSFS was just the most demanding program he used which brought to his attention there was a problem. Hopefully the original poster discovers the real problem hardware or software.

It's also worth mentioning that, if MSFS takes his CPU to 100 °C, then real stress tests like Prime95 or even Cinebench would induce severe thermal throttling or crash in a few minutes.

My CPU barely gets warm and stays under 25% usually.  GPU stays > 95% but stays cool.

Same here. I have a deepcool castle 360ex AIO, plus a case with really good airflow. Surprised that his cpu is overheating when for many others it's not even going above 40%

5900X here, my first AMD.  12 cores.  Eats MSFS for lunch. 🤩

I have also seen some unusually high temps on my 5900x. Up into the 80s. Other games i get 70 to 73 max. Something is definitely not right with the sim.

My R9 5900X also goes to 80-85C in the sim. But CPU usage is highest in urban areas where the CPU has something to chew on. In desert, ocean, less complex areas the temperature sinks a little bit. But 80-85C is within normal range for AMD 5000 series.

This was pre last update. I haven't checked since.

MSFS is cooking my computer. core temps well over 100 degrees C after this last update. It made me open up my entire system and dust it out. Ive lower power management to optimal. Ive lowered settings. I really thought it was just my system but Its not and I can confirm this last update is a huge issue.

Have you guys with temp issues tried testing your CPU temps with a loop of Cinebench or OCCT (on small dataset, extreme mode, steady load)?  I get same or higher temps in those than in the sim and none of them including the sim are anywhere near max allowable temps.  If you haven't check with an outside tool you should because if you have the same problem in there then you need to rethink your cooling solution, fan profiles, etc.  

Don't get me wrong, I'm not saying there's not an issue in the sim, it's absolutely putting a higher than normal load on the CPU compared to pre-SU3.  However, if it's cooking your CPU there's mostly like a cooling issue somewhere.  Either insufficient CPU cooling hardware, dust, too high of an overclock, bad fan profile not giving enough airflow, or a combo of those.  

I always stress test my overclocks with Prime95 for 24hrs. You'll find people in overclock forums saying "but the system will never get that hot!" or, my favorite, "the CPU isn't supposed to be stressed that much!" If the CPU can run the code, it should be able to do so within its thermal limits. If it's getting too hot, that is on your cooling. Maybe the latest MSFS update has inefficient programing that isn't giving you the performance you should be getting at that CPU usage, but those temps are still on you.

My cpu has been up in the mid 80 ever since this stuttering issue happened, temp is around 50 to 60 then the CPU hits 100 percent and the stuttering start for up to a few minutes, during this time the fans roar and the cpu temp hits 80 plus,this is not a PC issue it's the Sim that's causing it,didn't happen before the bug maybe for a few seconds at times

I did.. And i found out that my mainboard was running crazy power and current numbers in PBO and causing cinebench r23 multi core to run up to 90c and the system is water cooled. Once i lowered those outrageous numbers (PPT, TDC, EDC)  to defaults the cpu (ryzen5900x) runs and boosts no problem.

As for the sim it sits in the 60s as it does when i run the cinebench r23 single core bench.. very similar temps and core usage scenario.
