More effective, install intake fan or open the door w a fan next to it???

As the title reads, i am having heat issues and i have a 90cfm exhaust fan. I also have a 50cfm exhaust fan, that i was thinking of cutting into the room, so the natural garage air can be pumped into my room. or should i prop the door open with a fan blowing into the room?? i also have one oscalating fan blowing over the ladies and another fan blowing at my light.

what do you all think will work better and control my heat. is 90cfm adaquete? i have a 4x4 x 6(height) foot room.

Thanks

garage air is musky as it is. But try it rather then leaving the door open and exposing light.

well where i want to put the intake, there is a vent cut into the house so it would bring fresh air into the garage and then into the fan and then in the room. i understand what your saying, it will still have some garage stagnet air but its cheaper than air condition.
