A gaming PC dumps 400 to 700 watts of heat into your room. In an apartment with no central AC that heat has nowhere to go. Fans make you feel cooler but do not actually cool a room. The real solutions are a window exhaust fan, a portable AC, or a ductless mini split. Solved from real experience cooling 55 GPUs in South Florida.
The room your PC sits in matters as much as the cooler on your CPU. Every cooling component inside your case is trying to transfer heat into the surrounding air. If that air is already hot, your coolers run out of thermal headroom fast. Fans alone moved 95-degree air slightly faster. A window AC helped but cycled on and off causing GPU temperatures to follow. A ductless mini split running continuously combined with a whole-house exhaust window fan was the only setup that produced stable temperatures under sustained load. Read the full comparison.
