When I purchased this PC about 3 years ago, it had Windows 10 Pro version 1803. When the next version was available, I updated and then tried to play The Sims. That was the first time my PC had ever had problems with the fan revving and getting real hot while playing. I did some research and saw that others TS4 simmers were having the exact same issue after updating Windows 10. So, I reverted to the 1803 version and the fan revving and overheating stopped. All this time I have played just fine. Zero problems. I postponed updating Windows hoping that the situation would eventually resolve.
