i have had my pc for 3 years about to be 4 and i just started noticing problems on it 2 weeks ago or 3, i have done everything by buying high grade thermal paste, refilling coolant pumps, and making sure there is air flow through it, though the pumps work they do not do anything to help as the cpu just rises to 115 C within 2 minutes if it started at 40 C, the only problems i have noticed is that whenever i am in BIOS the CPU FAN 1 is N/A but I am unsure, any help?
