The wife thinks I am crazy. I ran a 4" dryer vent from the basement window to the case fan on the side of my PC. Due to the high humidity over night, I pull the vent out of the window and let it draw a mixture of room air and outside air.

If you used pvc piping, instead of the flexible stuff, your cooling would be more efficient. what you could do is install ball valves to close the flow from the basement, and another to open to the air in your room too.
