Been gaming and just taken a look at the air flow at the back of the laptop (g73), on the right vent (looking towards the monitor) im getting good airflow, lots a hot air coming out :), while in the left i don't seem to be getting any, is this normal?

I'd also like to know which vent is for which component (cpu or gpu) and also, what are the safe operating temps for both as well.

Any help will be appreciated.
