Fenix A320 and very high CPU temperatures

[hvw]

Hi all,

Did this ever, or still, happen to any of you? While performing a flight with Fenix A320 the CPU is getting (over)heated to 100 Celsius? It happens to me during most of my flights with the Fenix A320. Weirdest thing is, that this only happens 95% or so of my flights. Once in a while CPU temperatures remain steady at around 83 Celsius, which is the same temperature when I use FBW's A320Neo.  

For your information, I mostly use FS2020 in combination with Fenix’ A320. Very seldom temperatures remain more or less normal (~80-85 C). I cannot pinpoint why the very high temperatures while running FS2020 don’t happen all the time, as said, 95% of the time I run into this phenomenon of overheated CPU. 

I decided to start up FS2020 with an empty Community folder but for the Fenix A320, just to make sure that nothing else could cause the issue. Even with an empty (almost) Community folder, the CPU is getting very hot. I noticed that this always happened at the same “spot”. Here is what I did to find this out.

Before starting FS2020 I rebooted the computer, I then started FS2020 and waited till the “World Map” screen was displayed. Here I selected a parking spot at an airport and then selected the Fenix A320 Airbus, original livery, no other liveries were installed. During loading of the A320 the Fenix login screen shows up for the first time, stating that Fenix is started. A few moments after this screen vanished, the temperature is going to rise, then the login screen is showing for the second time, stating Fenix is started and at that point the temperature already rose to 95 Celsius. Then I hit the “Fly” yellow button and FS2020 becomes ready to fly at the selected spot of the selected airport. Temperatures are up to 100 Celsius within a few seconds now and remain that high for the duration of the flight.  For your information, Fenix A320 is fired up with “Turn Around” as default startup panel state.

To make sure that it might be Fenix A320 that causes the above, I exchanged the Fenix A320 with FBW’s A320 in the Community folder. Repeating the startup sequence as described above, CPU’s temperature doesn’t get above 85 Celsius. 

It doesn't matter whether I am on DX12 Beta or DX11, TAA or DLSS, temperatures are rocketing sky high. Nor does it matter if I throttle back from "High" graphic settings to "Medium" or "Low". (Graphis driver is NVidia driver 522.25)

My computer is two months old now, specs in my signature, I assume it is not my hardware that's leaving me out in the cold, the heat in this case. Strange thing is, that this issue only happens with the Fenix A320.

Any of you run into this same issue?

I believe there is a bug that has been occurring with RTX cards and temp. From what I saw it was not aircraft specific but platform (MSFS & RTX). You might want to google those topic and see what you can see, and yes…the behavior you describe is not normal.

Hello,

I found numerous posts on other forums in regard to high cpu temps on the acer preditor 630 and 640.  Some people have been able to replace the cooler that acer used and have better results. Any other games or applications running hot?

Thanks for that info. But isn't it strange that this only happens with the Fenix A320? Anyway, I am going to search for this reported bug.

Nope, only Fenix A320 that's making my CPU going berserk.

I don't think there is anything wrong with the fans, though, as when I run them at double speed (awful noise) the temp is going down considerably.

Sounds like a cooling issue with that unit or case.

Yep very strange. On my older computer running 8700k my cpu temps are in the upper 50s with an occasional spike into the lower 60s. That’s with the fenix and pmdg 737s. No difference for me when using the fenix a320.

You could try to reseat the CPU cooler, and swap out the thermal paste while you're at it. 

Or buy a better cooler.

I am on a 3-month old build and have my iCue Cooler LCD set to show temps so I always see it through the case.  It stays right at 45 degrees running pretty much anything in MSFS including the Fenix.  I have never seen it go above that.

What cooler do you have for your CPU? and what is the fan configuration in your case?

You say that in the FBW your getting 85 degrees? Even that's nuts

I have an i7 12700K @ 5Ghz on all the P-Cores and my CPU temp rarely goes above 50 degrees in either the Fenix or the PMDG and I fly the Fenix a lot.

Thanks, Bob. But why only with the Fenix A320 and not even all the time? I would expect if there was a cooling problem, it would be there all the time and true for both 320's, Fenix and FBW. 

I wished I understood what they wrote in the article you pointed me, too 🙂 I'm a true hardware no-know.

I've got two left hands, what my eyes see, my hands destroy.

The Fenix probably works your PC harder than any other program  you are running, and that is when it overheats. I googled your model of PC and came up with several CPU overheat threads, so I am guessing that may be an issue. Is it still in warranty, if so, I would contact the manufacturer.

Thanks. I unfortunately haven't got a clue on tech data for the coolers. There are 4 fans in the case, one for the CPU, one for the GPU, one in the front part of the case and one in the back.

I will call them, but it still puzzles me why every now and then the Fenix runs fine (temp-wise) on this PC. I'd assume it would overheat all the time with the Fenix. But I will contact them and see what the've got to say.
