Fan Mount Adapter for Rigol DHO800 Oscilloscope (92mm Be Quiet! Fan)

The adapter helps improve airflow and device cooling under prolonged use or high ambient temperature. Designed to be installed without modifying the oscilloscope — it uses existing screw points and aligns with the stock vent grid.

Fan installation is straightforward using standard 92mm mount points. The plate is printed in PLA, PETG, or ABS — depending on the thermal demands of your environment.

Print Settings:

Material: PLA, PETG, or ABS

Layer height: 0.2 mm

Infill: 20–30%

Assembly Instructions:

Unscrew the two original screws on the rear vent of the Rigol oscilloscope.

Align the adapter plate holes with the device's vent frame.

Mount the fan to the adapter using 92mm screw holes.

Reattach the whole assembly to the oscilloscope using M3x10 screws (or reuse originals).

Note on Fan Wiring and Installation:

The original built-in fan inside the Rigol DHO800 oscilloscope is removed during this modification. Its power cable is carefully desoldered (or disconnected, depending on the model) and re-soldered to the newly installed external 92mm fan.

This allows the new fan to operate using the oscilloscope’s original fan power supply, ensuring automatic control based on internal temperature regulation.

⚠ Important: This modification requires basic soldering skills and voids the warranty. Proceed at your own risk.
