Adapter Plate for Mounting a Fan to the Back Panel of the Rigol DHO800 Oscilloscope

This is a custom adapter plate designed to securely mount a cooling fan to the rear ventilation area of the Rigol DHO800 series oscilloscope. The plate allows you to attach a 92mm "be quiet!" fan (or similar) directly onto the oscilloscope's rear panel, improving airflow and helping maintain optimal internal temperatures during extended use.

The adapter plate is 3D-printed and aligns with the oscilloscope's existing vent slots, ensuring minimal airflow obstruction. It is mounted using the original screws or small bolts, and the fan is fixed to the plate via standard 92mm mounting holes.

This modification is useful for users who operate their oscilloscope in warm environments or under heavy usage, where additional cooling can improve reliability and lifespan.
