WARNING: It is essential to have previously installed Braiins OS+ on your miner, or any other software that can reduce the performance of your machine. This measure is crucial because, in order to reduce noise, we will install less powerful fans that can dissipate less heat.

WARNING: First of all, before starting, make sure you have unplugged your miner to avoid any risk of electrocution.

First, remove the 6 screws on the side of the case that hold it closed. Once the screws are removed, carefully open the case to remove the plastic protection covering the components.

Next, it's time to remove the original fan, taking care not to damage the other components. To do this, remove the screws that hold it in place and gently peel off the white glue surrounding the connector. It is important to proceed with care to avoid damaging the wires or connectors.

Once the original fan is removed, you will notice that the connectors of the new Noctua fan do not match those of the original fan. Indeed, the new fan has 3 wires, including a yellow wire that allows for speed control. However, this wire will not be used in this specific case. To connect the new fan, it is therefore recommended to use a special adapter. However, it is essential to note that this adapter can sometimes be challenging to locate.

If you do not have this adapter, you can still proceed to connect the new fan using an electrician's sugar. To do this, you will need to cut the cables of the old and new fans.

For the new fan, use a cutter to carefully cut the contours of the main sheath at 1 cm, without cutting the sheaths of the cables underneath.

Then, by pulling the main sheath downwards, cut the sheaths of the red and black cables in the same way as before. And cut the yellow cable flush.

On the old fan, it is more delicate to cut the main sheath without damaging the sheaths of the red and black wires. For this, we used a needle that we slid between the main sheath and the red and black wires.

Once the red and black wires are exposed, cut the sheaths carefully to avoid damaging the electrical wires.

Then, connect the cables with a sugar, the black wire with the black, and the red wire with the red. You can also add electrical tape.

Once the connection is made, it's time to install the new Noctua fan with the grille and the old screws. The new screws in the box will be reused later. Ensure it is placed in the correct orientation. You will notice an arrow on one side of the fan, indicating the direction of airflow. It is important to position the fan so that this arrow points towards the inside of the case. Then reconnect the fan.

Optional: If you are knowledgeable in electricity, you can directly add a female 5.5mm jack connector to the 12V power output, which will power the Vonet Wi-Fi bridge directly. However, if you are unsure of your electrical skills, it is best to use the USB connector with a smartphone-type charger to avoid any risk of short circuit or electrical damage.

Once the connections are made, place the plastic cover over the case plastic and not inside.

Finally, put the case cover back in place and screw the 6 screws on the sides to hold everything in place. And there you have it, your power supply case is now equipped with a new fan.
