Can you show photo of inside view of the system?as you can see from the first image, the CPU fan is already at full blast (3400RPM), so hopefully that can also help determine what has failed.
posted as requested and THANK YOU for your ideas!!!Can you show photo of inside view of the system?
I'd suspect cpu cooler to be insufficient for the system (or improperly installed or broken).
Does your system have any intake fans too?
Can't see them in the photo.
