I live in Canada where it can get down to -10C during winter, would it be theoretically possible to use air ducts to direct cold air from outside right into my PC's intake fans? It's just an idea I thought of, I'm not actually planning on doing this.

Edit: I know that condensation can cause water to build up (since the hot water vapour inside the PC could be condensed by the intake of cold air), but can condensation possibly be avoided if I did something like this - tubes directing air straight from the fans to the CPU and GPU?
