what about the idea to replace the internal speakers, most of us who want sound use external speakers anyway , so replacing the speakers with 2 fans which then would sit at the perfect place ,would make more sense then some fans underneath
but a bigger exit slot for the air would help too , as someone pointed it out already , hot air is rising and this tiny slot looks nice , but restricts airflow there is a reason why some other manufacturers of AIO systems have many many openings for hot air to get out/cool air coming in ,
design is one thing and apple tries to make a compromise to keep a slim clean look at the back which hardly anybody sees once the iMac is on a desk and the rear is facing a wall
but never mind , this discussion is as old as the first iMac G5, but apple has a idea of a case design and sticks to it, they fitted intels in the iMac G5 case and hey heat wasn't much of a issue any more , so the conclusion for apple was to make the case even slimmer, because less heat means longer liftime of the components , not ideal if you want to sell new computers if the old ones last and do the job, its not in apples interest when the imac last longer then apple care , you are supposed to buy a new one , so they have to find the middle way of long life and still convince you to buy a new one , not a easy task if your old iMac still does happily whatever you throw at it
i personally would love to see a convection cooled iMac again , just like my iMac G3 , no fans needed running since 10 years no breakdowns , still usable for browsing , emailing , watching dvd's , some photoshop and even playing some old OS9 games , and there is no heat issue , 10 years running is a sign that it was possible to build a iMac that lasts without needing apple care , but not good for profits
i understand nobody would buy today a crt , ok fit a lcd ,but please a matte one and make the whole iMac then convection cooled, all thats needed would be a case design that makes room for heatsinks that are up to the job ,without having fans to rev up when the computer is in use, positive side effect less components, less aluminium due to ventilation holes and cheaper , which should be in apples interest
