Introduction
Thank you for purchasing this upgrade board. In this short guide I will go
through the main steps of how to install the board, so lets begin!

arising from the installation or use of this upgrade product for your Prusa
printer, including, but not limited to, direct, indirect, incidental,
punitive, and consequential damages. The user assumes all responsibility and

Prerequisites
No soldering is required for this installation; it’s a simple plug-and-play
process 🙂 Before you start, ensure you have the fan upgrade board in hand.
Installation
Note : Ensure the device is powered off during installation to prevent any potential damage.
- Start by unscrewing the lid of the Rambo board to reveal the internals (Figure 1).
- Unplug the fan from its connector, marked within the white oval in Figure 1.
- Connect the fan upgrade board to the Rambo’s side, ensuring that the wire colors match the labels on the board (black to black, red to red, yellow to yellow) as shown in Figure 2.
- Connect the fan to the upgrade board, again aligning the text on the board with the correct cable, as illustrated in Figure 3.
- Once connected, tuck the board away in the available space within the case (Figure 4). Be cautious not to pierce the shrink tube covering the board as it could lead to short circuits!
Adjusting Fan Speed
To adjust the fan speed, use a small screwdriver to rotate the potentiometer
located as illustrated in Figure 5. Rotating it clockwise increases the speed,
while counterclockwise rotation decreases it. Avoid reducing the speed too
much, as it may lead to clogging. Gradually adjust the speed until you reach a
desirable noise level. You are now done with the installation, enjoy the
silence.
