Round Desk Fan for 120mm PC fan

thingiverse

I built a silent fan enclosure for my office to house a 120mm cooling unit quietly. The design is rounded to conceal the PC fan, which would otherwise be unsightly. The fit is as tight as possible given the fan's size. A 20dB fan with 50cfm airflow was chosen for its low noise level and gentle air flow. It's almost inaudible and provides a soft breeze. For the stand, I used a polished 8mm steel rod left over from another project. A similar material like wood or bamboo would work well due to the fan's lightweight design. A printable rod is included as an alternative option. The large rings have an outside diameter of 175mm.
