>>51043873Unless you have a case which is completely air tight except for the fans then all your diagrams and explanations about how this aircooling, or that aircooling, works is nothing but rubbish. The majority of the cool air will be pulled in by the inlet fans but some air will get in through the air vents and cracks. On the exhaust side hot air will escape through the fans and other vents and cracks. A computer really only needs two fans and that is the cpu cooling fan and one exhaust fan. All other schematics are utter nonsense
