¶ Issue Description
Common Issue Descriptions:
- The power supply has a very loud grinding noise
- The fan in the power supply has begun making a loud noise, and it sounds like something is rattling around inside.
¶ Symptoms
- Unusual loud noise
¶ Possible Causes
- The rear fan of the power supply is malfunctioning, causing an unusual noise.
- The internal fan of the power supply is faulty, resulting in an unusual noise.
¶ Troubleshooting Steps
¶ 1. Turn off the power, remove the four screws securing the backplate of the power supply
Tools required: H1.5 hex key
¶ 2. Gently pull out the backplate without fully removing it.
¶ 3. Disconnect the wiring of the rear fan.
¶ 4. Reattach the backplate, turn on the power, and check if the unusual noise is gone.
¶ Solutions
¶ 1. Replace the small rear fan.
If the noise stops after disconnecting the rear fan, it means the loud noise was coming from the small rear fan of the power supply. Please reach out to Snapmaker Support to get a replacement fan.
¶ 2. Replace the power supply.
If the noise continues after disconnecting the rear fan, it’s likely due to the internal fan of the power supply. Since replacing the internal fan can be challenging, please contact Snapmaker Support to get a new power supply or internal power unit.
Note: If it’s confirmed that the unusual noise is caused by the internal fan of the power supply and you have experience with replacements and feel comfortable doing so, you can purchase an internal fan for the SM 2.0 power supply, which uses a 6012 fan. Here’s an Amazon link for your reference:
This procedure carries a risk of electric shock, so it should only be done after disconnecting the power. We don’t recommend attempting this unless you’re an electrician or a professional.
