I've recently been streaming poker -- 4 to 5 hours at a time.
When I first started, my graphics system was the on-board video.
While streaming, and playing several tables, the GPU would be running at 100%, the CPU likewise, and temperatures would get so high the computer would shut down.
I recently purchased a used MSI GTX 960 graphics card and after a few days messing about, it is now installed and working.
What an education.
At the 15 hour mark I sit down, do a few emails etc.
I start streaming at the 12-hour mark. As the temperature rises to near 80C, you can see that the clock trace goes flat -- this is the Intel i7 processor's "thermal throttling" -- it slows itself down to prevent overheating and damage. You can see that the CPU load (orange) never reaches 100%, and the GPU load (brown) ticks along at about 40 -- with a few spikes. The fan speeds do what is expected. What was NOT expected was the GPU fans not coming on at all until the GPU reached 60C.
Ambient temperature seems important. Look at the slow fall in temperature from the left-hand edge to the point where I start to use the computer.
Here is the graph that the notes refer to:
