I would put the tank in your computer room where it's warmer. I wouldn't worry too much about the noise. When I had glass tanks, they were in my game room and Battlefield gets pretty loud at times Never saw that it effected the snakes. Just make sure that you have hides for them so they can do their thing.

Also, you might want to close the top with foil so the heat doesn't escape as much. Here's a good thread on how to setup a glass tank:
