Simagic Alpha Mini Cooling Shroud
thingiverse
Not the most refined design but in my testing so far, it did help drop temps by about 10-11 deg. C. Intended for use on Alpha Mini bases that are fastened from the bottom (will not work if the simagic side mounts are used and may not work well with front mounts as the airflow will likely be restricted) Intended for a single 120mm USB PC Fan (I used an AC Infinity Multifan S3 fan which you can get on Amazon). For mounting the fan to the shroud, you can tap M4 threads into the holes on the mounting flange and use M4 screws (which is what I did), or you can use similar sized self-tapping screws.
