I have a new Ultrawide Monitor AW3418DW and my old graphics card did not have any display port outputs. So I purchased a GTX2070 Super. My system is: Asus MB P8P67Deluxe with 17 2600k air cooled. 750watt power supply. I installed the GPU no problem, install the latest drivers and booted up. All worked well until I tried to game. A couple of tries on a few games proceeded to shut down my system with no warning. It automatically rebooted to my desktop. I downloaded CPUID? and I think it showed the temp at idle of my 4 cores in the 30-40 C range with a high around 50. Sorry I don't know how to read the graph. I tried the games again and had the same result. Airflow should not be the issue since my case is completely open and sitting on my desk. My problem is: How do I know if I have a overheating problem, and is it the OC graphics card or my CPU? I'm on the verge of taking the GPU back because all these games ran perfectly fine with this CPU and a dual monitor setup before I installed the GPU. Any thoughts?
