KKSB odroid HC4 80mm Fan mount

thingiverse

The KKSB case for the Odroid HC4 cannot receive a fan by default, I created this model to add a 2cm thick 80mm fan on top of the case by replacing the top cover. temperatures are way lower, idle CPU temp decreased from more than 60C to 40C, my 2 3"1/2 disks lowered from 50 to 35C. I installed the fan so that it pushes the air from the top to the lower in order less dust is entering the NAS, but you can use it in the reverse direction which is maybe more conventional, cpu will then receive 'fresh air'. My random 80mm pwm fan is turning at ~700rpm with very few noise and no vibrations. this is one of my first creation with Freecad so please be indulgent.
