Hi, I know it's not a bright idea to keep the screen closed when you're gaming on the 13" MBP and you're using it's screen as the primary one, but when you're using an external monitor is it a good idea to keep the screen closed? Will there be overheating on epic levels? I say this because whenever I play games for extended amounts of time (with the screen open) I fear that my home will burn down because of the fan noise and heat of the notebook around the area above the function keys. For aesthetic purposes I would like to keep the screen closed but I'm not sure what would result from this. Thanks!
