recently i've been lagging on CS:GO my ping fluctuates from 30 to around 70 but it's usually around 30. I checked my cpu temp and it goes to 72 or 80 when i play. Is my cpu the problem?
Even for core temps that is pretty high for gaming. If the case temp of the chip is that high, then you may be throttling. List system specs and software used to monitor temps please.
