Well,

no, it's not what ya think - not a girl, not that great addon, but actually my old 960 GPU installed in my new desktop which was built for a new generation of MFS and XP.

I have been experiencing a huge increase in T of the GPU, and accompanying fan speed ... This happens as soon as I start MFS, and is specially intense along a normal flight.

I have lowered the graphics settings, but the "problem" persists.

Before, when I was running MFS in the old desktop, with an old i5 2500 , the GPU was never under "stress".

Top T reaches 75+ ºC !!! Wow that's as hot as I was ever able to see it reach.

Using the dev console to monitor FPS and CPU / GPU stress I see that while the CPU is normal is at, say, 9% use, the GPU OTOH is used to the limits...

My new rig is based on AMD technology, Ryzen 5 5600 X 6 core, I have 32 GB top RAM, and a 1TB MVme PCI-e SSD "disk"...

Any suggestions on ow to throttle the GPU ?

I use the MSI afterburner for tweaking the fan speed. With it I can specify a curve the fan speed will follow.

But if your GPU is on 100% all the time this will not help.

Is there enough air in your rig? You can try to run MSFS with your rig open and see if the GPU runs cooler.

I have managed to lower T by setting limits to FPS in both Nvidia Control panel and MFS.

I set max FPS in NCP to 30, in MFS the same + VSync... I recall somewhere I should be using 60 ( ? ).

My monitor is a vanilla HP HDMI @ 60 Hz

I also have an older gen GPU - GTX980Ti. I set VSync on and 30 FPS in the sim and don't touch any settings in the NCP. You don't need to. Excellent performance and GPU is not under stress. All settings on High, not Ultra.

Is there a reason why you think 75C is bad?  Sounds normal to me.

Every temperature <85°C under load of GPU is normal and OK. So there does not exist any problem.

It is, most modern GPUs won't let you burn them out anyways - they'll thermal throttle far in advance of that.

1. The 960 might need new thermal paste and pads

2. High GPU utilization is typical of MSFS, and starts already in the menus

3. 75C is not high for a GPU. 85C is normal. 

4. The reason you're seeing higher GPU temps now with the R5 compared to the old i5 is that previously your i5 might have been holding the GPU back. The CPU is now not the bottleneck, the GPU is.

honestly, I dont think anyone thought that.  wrong type of forum.

The hot girl could have been an airplane, though.

Most likely.

Often the thermal solution on a GPU is poor from new and only gets worse with time.

If you really want to keep the 960 consider:

• redoing the thermal paste with something like grizzly or NH2 (NOT liquid metal)
• under-volting the GPU a smidgeon
• ramping up the fan profile a bit

Capping your frames really helps to keep your GPU temps down also, especially if you have the settings cranked up. I cap mine at 45 FPS and it keeps my GPU around 70c even with the settings close to Ultra at 1440p.

Well guys, thank you all for the suggestions.

Maybe I wasn't really aligned with reality in thinking that 71 - 75 ºC are too high vales, when I see 100% use in my GPU on the monitoring tools, but I've been told by Alexis it is actually pretty much acceptable and normal.

My aim is to upgrade to some modern / fancy GPU, but for the time being this 960 is still doing it's job rather nicely. It was a top card when I bought it some years ago :)

I used the capping to control T and it works. 

.) At first I used the Nvidia Control Panel ( NCP ) 3D profile capping, by setting max FOS to 60, then 30... but I returned the value to default no capping;

.) Also in NCP, instead of using the "High Performance" setting I downgraded it to "Optimal Performance";

.) In MFS I set max FPS to 30 and enabled VSync. I recall there's some trick regarding this, namely that the FPS max setting could be a bit above 30 when enabling VSync, but I wasn't sure, so, it is set that way.

Altogether it worked acceptably :-)

 

If you're unsure about re-applying thermal compound, at the very least consider giving the cooling fins a good blast with compressed air while holding the fans stationary.  May be a lot of dust in there on an older GPU.  My old 960 ran about 25 degrees cooler after new compound and a good clean out.  It had been throttling something terrible in P3D some years back until realised what was happening from graphs in MSI afterburner (CPU utilitisation, versus temp etc).

Very happy now with GTX 1660Ti upgrade in this older box to gain a bit more longevity.
