Say we're in the middle of the summer and your GPU is mining away happily, and you want your target temperature to be 70C. You can tweak MSI Afterburner/trixx til the line graph is close enough that it's about 70c while you just tell the OP's program what temperature to be at, and adjust fan as necessary (We'll assume you need 60% fan speed for this).
Now it's winter and much colder. Your trixx has the same graph, and now your GPU is at 60C, likely at a lower RPM than in summer. OP's program will still have the GPU targeted at 70C, and the fan needs even less RPM than trixx to achieve the target temperature, so it's kind of smart when it comes to different ambient temperatures.
See, ssateneth was a smart guy, very, absolutely. ^_^
Anybody skill of program or debug or analyze who will say: The program didn't call any API of NET or Internet, it's safe enough.
If you still wary about it, don't run it with wallet in the same machine.
I get nothing until somebody pay me for custom. wish somebody post feedback of it.
