Inline 4 inch Booster Fan using 120mm CPU Fans
cults3d
This was designed as an inline booster fan replacement, purchased after finding the original fan excessively noisy in my office space. I sought out a more silent solution that wouldn't break the bank. It utilizes four 120mm 12VDC CPU fans. The CFM is comparable to the booster fan I replaced, but the pressure falls short. Nevertheless, it ventilates my resin printer decently while being significantly quieter. Required Hardware: * Four 120mm CPU Fans * One 12VDC power supply (ensure you calculate the required power for the four fans) * Sixteen 8-32x1.5" machine screws * Sixteen 8-32 nuts with washers The "Nut Gasket" models have a recessed cutout for the nut, making it easy to install everything with just a screwdriver. Once all pieces are assembled, I used duct tape to seal all seams and gaps.
