Description

Hi, the site stop to work as a shop, if you are interest, you can find the model here: CGTrader Shop https://www.cgtrader.com/sgabo...

This is a conversion kit for 120mm PC fans. The kit was born from an idea that proved to be very effective. This design has been tested on two 3.84 watt and 6 watt fans with doubling of pressure. Obviously the fan flow is halved. Equally obvious that the faster the rotor turns, the more pressure and flow is produced. I suggest using fans of 3 watts or more.

Dimensions supported by the kit 

  • The kit is made for an engine diameter between these: 36,37,38,39,40,41,42 mm 
  • The maximum height of the motor is 23 mm

In this video the assembly of the kit is shown and then the test is shown with a few calculations.

The design is optimized to be printed with 0.4mm nozzle

Among the files you will find two covers, the "cover-plus05" adds 0.5mm of space in height if you have not been very precise in installing the impeller. Or in case your motor moves too high.

I added rings with a thickness of 0.5 - 1 - 1.5 mm, but if the thickness you need is different, you can make a resize on the Z axis with the slicer to get the thickness you need.

Suggest print option for the impeller:

  • Wall 0,8mm
  • Top/buttom 0,8-1mm
  • infill 10%
  • support only touch bed and angle over 70% (you need have support only for the hole)

Normal radial fans have a dead zone of 20-25% which does not produce pressure, with this design there is no longer a dead zone and the whole fan is used to generate pressure. Not only that, more explanations in this video:

In this other video the first comparison test with a 6 watt fan.
