So, a lot of folks on here hate on modders. Apple engineering can be improved. Note I am not including a photo of the hacked up bottom case of my MBP Early 2011. Its a rough draft and another bottom case has been sent out for laser cuts. Here some good stuff for you. First SS is with vents and system managed fans. Second SS is no vents and system managed fan. Third is vents and sensor managed fans. See the differences? OMG BUT THE AIRFLOW OVER DA MOTHERBAORD! See the drops there too? Yeah. Us modders? We win.
