some time ago a problem appeared, I use Windows 11 and Mac OS in these OS the video cards overheat in the task manager it does not show that the video card is loaded but in the program for the video card it shows 100% load on video card number 2, in Mac OS the video cards are also loaded. I do not know where to start looking for this problem, Windows is completely reinstalled. I will be very grateful if you write some advice
 
Is the GPU running a load, or just has an elevated temperature? Also, got anything interesting plugged in, like an 8K monitor?

Under macOS -> Activity Monitor -> Window -> GPU History (or Command-4)

This will show processing load for each GPU. I don't know how to do this under Windows.

If it's just elevated temps on GPU #2, with no corresponding load, then the heatsink grease probably needs redoing on GPU #2. If it is dried out grease, I'd redo it on both GPUs, and maybe even the CPU. Assuming it's the factory grease, all three are the same age.
