2012 mbp non-retina - how does it ventilate?

[Voodoofreak]

I can't find any "normal" outlets for heat on this notebook. Where is the heat dissipating from? I'm wondering if I would ever need to do air dusting cleaning of the fans.

air comes in from the left side where your usb and other ports are and comes out the back where the screen hinge is.

also i clean the fans with canned air every year or so.
