I built this PC about 6 years ago. I have never overclocked it. Recently when playing video games (mostly the Division 2) I have been receiving temperature warnings about the CPU. My cpu temps after about an hour of playing rises to between 65-70C. However, my V-Core 1 temp is very high at the same time, between 70-75C. I replaced the CPU thermal paste, I use Arctic Silver Ceramique. Still no temperature drop. My case is well ventilated with 2 front fans drawing air in, 1 bottom fan drawing air in, 2 top fans exhausting air out and 1 rear fan exhausting air. PSU draws air from bottom of case and exhausts. I am unsure whether the CPU is the problem or if the Motherboard is dying? Could it be anything else?
