RE: Aurora R4 and GTX 690 pinging when running GPU stress programs. I guess the GPU is telling me that it is overheating? I believe I bought this Aurora R4 in late 2011., so it's about 5 years old.
Yes you can also hear the pinging through the headphones. I am running the latest BIOS (A11). I ran 3D Mark 11 Basic version and the temps got as follows: GPU0 - 174 degrees F. & GPU1 read 170 degrees F. It takes no time to start pinging once you stress the GPU.
