¶ How to handle noise from the auxiliary fan?
-
Check if the fan blades are tangled with waste filaments:
- Turn off the fan power to ensure safety.
- Carefully inspect the fan blades to see if there are any printing waste filaments or other foreign objects tangled or stuck between the blades.
- If there are filaments found, use tools (such as tweezers or pliers) to carefully remove them without damaging the blades.
-
Check if the fan blades are intact:
- After removing all foreign objects, check if the blades have any cracks, breaks, or bends.
- If the blades are damaged, this could be the cause of the noise. Damaged blades may need to be replaced.
If the noise still exists after these two steps, consider the following additional checks:
-
Check the fan bearings:
- Worn or damaged bearings can also cause noise. Check if the bearings need lubrication or replacement.
-
Check the fan balance:
- If the weight distribution of the blades is uneven, it may generate noise when rotating. Check if the blades are balanced and make necessary adjustments.
-
Check the fan installation:
- Ensure that the fan is securely installed and there are no loose parts, as these can also cause noise.
¶ How to handle reduced wind force from the auxiliary fan?
-
Power off:
Make sure the fan is completely powered off before any cleaning to ensure safety.
-
Use a soft brush:
Use a soft brush (such as a paintbrush or a special electronic device cleaning brush) to gently brush off the dust on the blades. Avoid using a hard brush as it may damage the blades.
-
Use compressed air:
If the dust is stubborn, compressed air can be used to blow away the dust. Make sure not to use too high pressure to avoid damaging the blades.
-
Clean the fan frame:
In addition to the blades, the fan frame and motor parts may also accumulate dust. Wipe these areas with a soft cloth.
¶ How to handle the auxiliary fan not spinning?
According to your instructions, here are the steps to handle the noise from the auxiliary fan:
-
Check the motherboard fan connector:
- Ensure that the fan power cable is correctly plugged into the fan header on the motherboard.
- Check if there are any signs of looseness or poor contact at the connector.
- If the connector is found to be damaged, it may be necessary to replace the connector or motherboard.
-
Dismantle the auxiliary fan:
- Carefully dismantle the auxiliary fan with the power off.
- Check the fan power cable and connection points to make sure there are no breaks or damage.
-
Check the internal structure:
- Open the fan casing and check for any signs of damage or broken wires inside.
- Check if the blades are intact, the bearings are normal, and the motor is functioning properly.
-
Problem with the fan itself:
- If no obvious problems are found in the internal inspection, but the noise still exists, it may be a problem with the fan itself.
- Consider replacing a new fan, especially if the fan has been used for a long time.
