I lock my 4090 at 36 FPS and with FG it gets to 72 (half my 144 refresh rate). I just try to get the smoothest performance without taxing my system, because otherwise the fans are louder, the heat is worse, power usage is more, etc. No value to higher FPS than you can actually see.

Unlocking the frame rate makes the PC work harder.
Harder work means more heat.
There must be better things to waste almost four minutes on.

thanks man, I made that video, appreicate the anger too lol

There are those amongst us, including me, who benefit from being reminded about such things. 

appreciate the kind words, thanks for watching , Pilot Pete

I enable g-sync and v-sync in the nvidia control panel so fps never exceeds the 165hz monitor refresh on any game. Saves a lot of wasted noise, power, and heat.

In fs2024 I also lock frames to 40 with 2x FG (80 fps) The sim just runs smoother that way.

me too...

No one is mocking the thread, not even me.
The 3 minutes and 45 second long video explaining that a device that works harder may well become warmer
is arguably not rocket science.
That's all.

then don't watch ... wow, a revalation.... My goal. Help only one person. So I did just that when i made the video

Oh please, not this urban legend again...

I have had my system pumping out 130 fps with fans blazing and temps rising, and yes technically it is “slightly better” than 72 fps (fg both), but definitely in my case not moving the needle nearly enough to justify the downsides.

I didn't, but I admire your motive.

Well, this is a completely differnt justification to the «more than one can see» statement above, no? 😉 I absolutely agree with this second statement, this is also the reason I limit my FPS to the exact same number.

This is worth a look - https://getfancontrol.com/

Pacifies my system a treat.

One of the best programs I have ever used, and it's free... The UI makes it simple and inutitive to use.

Being able to control case fans by a combination of GPU and CPU temp is the best feature.

Been using this for a couple of years now. Excellent free app that lets you control fan cooling to the teenth.

I guess. Technically i can barely see a difference and at 72 fps my system is already butter smooth. Diminished returns after that.

Not seeing the point of the video, except the obvious?

Similarly, I find when I shutdown MSFS on my PC (and after I shut down my PC altogether), the GPU and CPU temperatures seem to go down.  Shocking, right?!
