Description
This is a slim mount for a 92mm fan on the back of your Rigol DHO800/900-series oscilloscope. It reduces the noise compared to the internal fan significantly and even lowers the temperatures by a few degrees. This made a huge difference in noise comfort for me.
The mount was designed to use the least amount of material and have a good ground clearance, even when the stand is tilted.
Please note that the original internal fan needs to be removed for this to work. Of course this will void the warranty, so do this at your own risk.
Required Material
- 1x Noctua NF-A9 FLX fan (around $20)
- 4x M4x10mm screws (for the VESA mount)
- If you want the protective grille, you need 4x standard fan mount screws (in addition to the 4 you've received with the Noctua)
Build Instructions
- Print the mount (was around 1h15 on a MK4S)
- Do the post-processing (see below, takes 2 minutes)
- Open up the oscilloscope (4 screws)
- Remove the internal fan (3 screws plus it is connected via a small plug to the board)
- Mount the fan into the printed mount with the 4 fan screws. Add the grille on top if needed.
- Cut off the plug on the end of the Noctua.
- Cut the original fan's cable and solder the red and black wire to the Noctua's cable (don't forget to add heat shrink tubing first)
- Plug in the cable onto the board.
- Close up the Rigol.
- Power up and enjoy the silence.
Recommended Print Settings
- Material: PLA
- Layer height: 0.2mm
- Infill: 15% or more
- Generate Support Material: ON
- Orientation: Back face (the one where it will touch the Rigol) down on the bed
Choose a nice grey color to match the Rigol's housing color - I've used white as I didn't have anything else.
Post Processing
As the fan mount holes are countersunk, there's a small gap with an overhang. This is why the model needs to be printed with supports. These supports need to be removed (just 4 very small pieces that cover the fan holes). Just use a sharp plier or similar to remove them. I've only tested this with PLA where it takes less then 2 minutes.
