Niwa growsystem - Noctua 120mm fan mount

cults3d

Made for Niwa growsystem(Niwa One). The Niwa originally comes with a 80mm fan. I think the fan was too noisy for living room. So I made this 120 mm noctua fan mount. I used Noctua NF-S12A ULN 120mm. 120mm fan is the biggest fan that you can fit in the space available. The mount directly replaces the original fan mount without the need to modify the plastic. To have the 120mm connected you need to cut the original cables to the 80mm fan and solder on the new fan. I used one of the cables included with the Noctua fan (extension cable). I soldered on the plug so you can replace the fan without soldering later. I used shrink tubes over every solder points. Noctua fan comes with some rubber fittings. these can be used to mount the fan without screws to the holes in this custom fanmount. The original 80mm fan cable is color coded red and black. Where red is 12v+ and black is negative. Please look at noctua documentation on color coding of their cables. it differes if it's a 3 pin fan or a 4 pin fan.https://noctua.at/en/what-pin-configuration-do-noctua-12v-fans-use
