Games live GTA (open world type of games in general) put a lot of stress on the CPU of your computer. If your CPU is overheating, its heat sink may not be seated correctly or its thermal paste may be improperly applied. You should start by cleaning of all dust and maybe try running the PC with open case. If temperatures are still too high, next step should be to replace thermal paste, heatsink (with a bigger one) and even the CPU fan if you have doubts about it's cooling abilities. Also keep in mind, that if you have overclocked components they will put out more heat and should consider a cooling upgrade in general (even a water cooling system in some cases). Hope this was helpful, Citizen_WD
