I've been searching a bit regarding airflow mods to the current style mini. It seems like the popular thing to do is to raise the machine up a bit, or remove the bottom cover entirely and sit it ontop of a large quiet fan. I've also seen the mod where the machine sits ontop of a peice of foam to act as a filter. Those all seem effective, but a bit overkill for my needs. I've been thinking more along the lines of just modifying the plastic cover to increase the airflow (look to be about $35 after shipping for a spare). Or just rigging up some sort of plate that integrates a filter for the intake and a block off for the rear section of the base. Mini location is vertical (power supply up) along the side of a cabinet with a book end as a support to keep stable. Temps and rpms don't change wether it is flush against the surface or spaced 1/2"+. There is a 1000+ rpm drop on the fan when base plate is entirely removed at full load. But this obviously disrupts the intended design of the airflow through the machine. I want to maintain the factory airflow path, just reduce the restriction. Has anybody done so and had positive results? Numbers: Base i7 2012 model. Bunch of ram, extra internal drive, 94 deg c 3500ish rpm encoding with base 94 deg c <2500 rpm encoding without base.
