Precision M7520 overheating

I received this new from dell about 2 weeks ago. They have agreed to replace it with a new machine. I have a few questions that perhaps others here can answer. I did some serious video encoding with the machine and the fans kicked on and all went well. I go and play a very simple MS game and give it 15 min and it does a warning saying "Shutting Down" and shuts down. Event log says its a thermal shutdown. What I have noticed is that the fans are at a normal state.. not at all wound up, just doing a slow idle.
I'm wondering what is overheating? Could it be the onboard intel graphics chip? does it not have a thermal sensor to jack the fans up? Any ideas would be helpful.

This is the even data:


EventData
ThermalZoneDeviceInstanceLength 43
ThermalZoneDeviceInstance Intel(R) Dynamic Platform Thermal Framework
ShutdownTime 2017-08-30T05:04:03.613974400Z

sorry for the double files.. they are the same.. I didnt see where they had attached so I tried again then just pasted the event in.

 

This machine should not be able to get hot enough to trigger a thermal shutdown, no matter how you load it. You need to contact Dell and have them repaste the CPU (and GPU?) or just have them send you a new unit if it is new.

You can use a tool like SpeedFan to monitor the temperatures while you are running your encoding job. It is safe for the CPU to reach mid 80's or low 90's (Celsius), but if it is pushing near/over 100 then that is a problem with the system cooling.

 

Dell has agreed to replace the system. It just bothers me than I perhaps did something wrong and it will happen with my new one. It's odd the fans dont kick on high before the event happens.

 

Maybe it gets hot too fast for the fans to even kick on? Or it could just be defective
